                            2000-2G Pass Through Trust
                     Pass Through Certificates, Series 2000-2G

                                  ------------

   This prospectus supplement relates to class G pass through certificates to
be issued by a pass through trust that we will form. Each pass through
certificate represents an ownership interest in the property held by the trust.
The proceeds of this financing will be used to partially finance twenty (20)
Airbus aircraft. The certificates do not represent interests in or obligations
of US Airways or any of our affiliates.

   Interest related to the certificates will be paid semiannually, on each
February 5 and August 5, beginning August 5, 2000. Principal payments related
to the certificates are expected to be paid on February 5 and August 5 in
scheduled years, beginning on August 5, 2003. The certificates will not be
listed on any national securities exchange.

   Bayerische Landesbank Girozentrale will provide a liquidity facility for the
certificates in an amount sufficient to make three semiannual interest payments
if the pass through trust does not have enough funds to make those interest
payments.

   MBIA Insurance Corporation will issue a financial guaranty insurance policy
to support the payment of interest on the certificates when due and the payment
of the outstanding balance on the certificates due on the final maturity date
for the certificates and under certain other circumstances as described in this
prospectus supplement.

                                 [MBIA LOGO]

   Investing in the certificates involves risks. See "Risk Factors" beginning
on page S-20.

   Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved these securities or determined if this
prospectus is truthful or complete. Any representation to the contrary is a
criminal offense.

                         PROSPECTUS SUPPLEMENT SUMMARY

   This summary highlights selected information from this prospectus supplement
and the prospectus, and may not contain all the information that is important
to you. For more complete information about the certificates or us, you should
read this entire prospectus supplement and the prospectus, as well as the
materials filed with the SEC that are considered to be part of the prospectus.
See "Incorporation of Certain Documents by Reference" in the prospectus.

The Offering

   This supplement describes our offering of pass through certificates to help
finance or refinance aircraft that we will own or lease.

   This supplement first describes the pass through certificates and the pass
through trust that will issue the pass through certificates. It also describes
the various agreements relating to the certificates. This prospectus supplement
then describes the secured promissory notes that the pass through trust will
acquire and, in the case of promissory notes secured by aircraft leased to us,
the owner trusts that will issue those secured promissory notes.

Certificates

   Pass through certificates are securities that evidence an ownership interest
in a pass through trust. The holders of the certificates issued by the pass
through trust will be the beneficiaries of the trust. A certificateholder's
beneficial interest in the pass through trust will be a pro rata interest in
the property of the trust equal to the ratio of the aggregate face amount of
all of the certificates owned by the holder to the aggregate face amount of all
of the certificates issued by the trust. Class G certificates will be issued by
the 2000-2G pass through trust and will represent beneficial interests only in
the 2000-2G pass through trust.

   As described in this prospectus supplement, the certificates are entitled to
the benefits of a liquidity facility provided by Bayerische Landesbank
Girozentrale. The liquidity facility is a revolving credit agreement that will
provide the pass through trustee with an additional source of funds to make up
to three consecutive scheduled semiannual interest payments relating to the
certificates. The liquidity facility may not be used to make any payment of
principal.

   The certificates are entitled to the benefits of a financial guaranty
insurance policy issued by MBIA Insurance Corporation to support the payment of
interest on the certificates when due, under certain circumstances, and the
payment of the outstanding balance on the certificates on the final maturity
date for such certificates and under certain other circumstances.

The Pass Through Trust

   We will form the 2000-2G pass through trust to issue the class G
certificates. We will form the pass through trust with State Street Bank and
Trust Company of Connecticut, National Association, as pass through trustee.

   State Street Bank and Trust Company will guarantee the performance and
obligations of State Street Bank and Trust Company of Connecticut, National
Association under the pass through trust agreement. The pass through trust will
be governed by a trust instrument that creates the trust and sets forth the
powers of the trustee and the rights of the beneficiaries. The trust instrument
for the pass through trust will consist of a basic pass through trust agreement
among US Airways, US Airways Group and the pass through trustee, and a

                                      S-2
<PAGE>

supplement to the basic pass through trust agreement. US Airways Group will not
guarantee our obligations under the pass through trust agreement or any other
agreement described in this prospectus supplement.

   This prospectus supplement describes, among other things, the property that
will be held by the pass through trust. This property will include promissory
notes secured by aircraft that we will own or lease. Payments of principal and
interest on the secured promissory notes owned by the pass through trust will
be passed through to holders of certificates, according to the terms of the
pass through trust agreement. The pass through trust also will hold other
property described in this prospectus supplement.

Secured Promissory Notes

   The secured promissory notes owned by the pass through trust may consist of
any combination of:

  .  Promissory notes issued by an owner trust and secured by an aircraft
     owned by that trust and leased to us. We refer to these types of secured
     promissory notes as leased aircraft notes.

  .  Promissory notes issued by us and secured by an aircraft owned by us. We
     refer to these types of secured promissory notes as owned aircraft
     notes.

   Leased Aircraft Notes. Leased aircraft notes will be issued by a bank, trust
company, financial institution or other entity solely in its capacity as owner
trustee in a leveraged lease transaction. In a leveraged lease transaction, one
or more entities will form an owner trust to acquire an aircraft, and that
owner trust will lease the aircraft to us. In the leasing industry, the entity
that is the beneficiary of the owner trust is referred to as an owner
participant. The owner participant will contribute a portion of the purchase
price of the aircraft to the owner trust. The transaction is called a
"leveraged" lease because the remainder of the owner trust's purchase price of
the aircraft is financed through the issuance of leased aircraft notes. Leased
aircraft notes may also be issued to refinance an aircraft previously financed
in a leveraged lease transaction or otherwise.

   The leased aircraft notes are issued under a separate indenture and security
agreement between the owner trustee and a bank, trust company, financial
institution or other entity, as loan trustee. The loan trustee under a leased
aircraft indenture will act as a trustee for the holders of the leased aircraft
notes issued under that leased aircraft indenture.

   In a leveraged lease transaction, we will pay or advance rent and other
amounts to the owner trustee in its capacity as lessor under the lease. The
owner trustee will use the rent and other amounts received by it to make
payments of principal and interest on the leased aircraft notes. The owner
trustee also will assign its rights to receive basic rent and certain other
payments to the loan trustee as security for its obligations to pay principal
of, premium, if any, and interest on the leased aircraft notes. Payments or
advances made under a lease and related agreements will at all times be
sufficient to make scheduled payments of principal of, and interest on, the
leased aircraft notes issued to finance the aircraft subject to that lease.

   We will not have any obligation to pay principal of, or interest on, the
leased aircraft notes. Holders of leased aircraft notes will not have recourse
against us for the payment of principal of, or interest on, the leased aircraft
notes.

   Owned Aircraft Notes. We may finance or refinance aircraft that we own by
issuing owned aircraft notes. Owned aircraft notes relating to an owned
aircraft will be issued under a separate indenture and security agreement
relating to that owned aircraft. Each separate indenture and security agreement
relating to owned aircraft notes will be between us and a bank, trust company,
financial institution or other entity, as loan trustee. We refer to the
indenture and security agreement entered into for the issuance of owned
aircraft notes as an owned aircraft indenture. The loan trustee under an owned
aircraft indenture will act as a trustee for the holders of the owned aircraft
notes issued under that owned aircraft indenture.

                                      S-3
<PAGE>


   Holders of owned aircraft notes will have recourse against us for payment of
principal of, and interest on, the owned aircraft notes.

   Because we often refer to owned aircraft indentures and leased aircraft
indentures together, we sometimes refer to them collectively as the indentures.

Delayed Aircraft Financing and Termination of Delivery Period

   We expect the certificates to be issued prior to the delivery of 13 of the
aircraft described in this prospectus supplement. Five of the aircraft
described in this prospectus supplement have been delivered as of the date of
this prospectus supplement and we expect two aircraft to be delivered prior to
the date of the issuance of the certificates. At first, all of the proceeds
from the sale of the certificates will be held in escrow and deposited with ABN
AMRO Bank N.V., as depositary. The depositary will hold the deposits until the
deposits are withdrawn to be used to purchase secured promissory notes or, in
the case of deposits that are not used to purchase secured promissory notes,
until returned to certificateholders. The depositary will pay interest on
amounts held as deposits as described later in this prospectus supplement.

   The escrow agent will withdraw and distribute to the holders of the
certificates any deposits remaining after the delivery period termination date.
The delivery period termination date is the earlier of (i) the date all
aircraft described in this prospectus supplement are financed, and (ii) March
1, 2001.

   Each certificateholder's interest in the corresponding deposit will be
evidenced by an escrow receipt attached to the certificate. The escrow receipts
may not be detached from the certificates, and must be transferred together
with the certificate to which it is attached and may not be transferred unless
the certificate to which it is attached also is transferred.

(1) This percentage is calculated as of February 5, 2001, the first regular
    distribution date after all aircraft are scheduled to have been delivered
    assuming the amount of principal due on that date has been paid. Regular
    distribution dates will be February 5 and August 5 of each year. In making
    this calculation, we have assumed that all aircraft financed from the
    proceeds of the sale of the certificates offered by this prospectus
    supplement will be delivered prior to February 5, 2001. We also have
    assumed that the maximum principal amount of the secured promissory notes
    described in this prospectus supplement will be issued and that the
    aggregate appraised aircraft base value will be $818,370,000 as of February
    5, 2001. The appraised base value is only an estimate of aircraft value and
    may not reflect current market conditions. See "Description of the Aircraft
    and the Appraisals--The Appraisals."
(2) The insurance policy will support the payment of interest on the
    certificates and interest on the deposits related to the escrow receipts
    attached to such certificates (in each case, when due and after taking into
    account the application of any amount received by the escrow agent as
    accrued interest on the deposits and the prior use of any available funds
    under the liquidity facility or the cash collateral account for the
    certificates) and the payment of the outstanding balance of the
    certificates due on the final maturity date for the certificates and in
    certain other circumstances as described in this prospectus supplement. The
    insurance policy will not support any payments of principal from the
    deposits relating to the escrow receipts attached to the certificates.

</TABLE>
--------
(1) The actual delivery dates for the first four A319 aircraft and the first
    A320 aircraft are set forth in this table. The delivery month for the
    remaining aircraft is the date that we expect the aircraft to be delivered
    by the manufacturer. This date may be delayed or accelerated. We have the
    option to substitute other aircraft if the delivery of any aircraft is
    expected to be delayed for more than 30 days after the month scheduled for
    delivery of that aircraft or beyond the delivery period termination date.
    The delivery period termination date is the earlier of (i) the date all
    aircraft described in this prospectus supplement are financed, and (ii)
    March 1, 2001. See "Description of the Aircraft and the Appraisals--
    Substitute Aircraft." We may take delivery of an aircraft and finance that
    aircraft under this offering up to 180 days after such delivery (or such
    longer period after such delivery as we may elect with approval from the
    rating agencies, but in any event not later than March 1, 2001).
(2) The actual principal amount of the series G secured promissory notes issued
    for any aircraft may be less than the amounts shown in this table. The
    aggregate principal amount of all the series G secured promissory notes
    will not be more than the aggregate face amount of the class G
    certificates.
(3) The appraised base value of each aircraft is the lesser of the mean and
    median base values of that aircraft as appraised by three independent
    appraisal and consulting firms. The appraised base values for the aircraft
    not yet delivered are projected values as of the month each aircraft is
    expected to be delivered by the manufacturer. The appraisals are based on
    assumptions that may not reflect current market conditions. An appraisal is
    only an estimate of value and should not be relied on as a measure of
    actual sales value at any time. See "Risk Factors--Risk Factors Relating to
    the Certificates and the Offering--Appraisals and Realizable Value of
    Aircraft."

Loan to Aircraft Value Ratios

   The following table shows the assumed aggregate loan to aircraft value
("LTV") ratios for the certificates as of February 5, 2001 and as of each
subsequent August 5, assuming the pass through trust acquires the maximum
principal amount of secured promissory notes prior to February 5, 2001. In a
default situation, the LTV ratios for secured promissory notes issued to
finance individual aircraft may be more relevant than the aggregate LTV ratios
shown below. This is because any proceeds from the sale of an aircraft or other
exercise of default remedies will not be used to cover any shortfalls on the
secured promissory notes relating to any other aircraft. See "Description of
the Secured Promissory Notes--Loan to Value Ratios of Secured Promissory
Notes." The LTV ratios for the certificates as of dates prior to February 5,
2001 are not relevant because the property of the pass through trust prior to
that date will not include all the secured promissory notes expected to be
acquired by the pass through trust. The table should not be considered a
forecast or prediction of expected or likely LTV ratios but simply a
mathematical calculation based on one set of assumptions. See "Risk Factors--
Risk Factors Relating to the Certificates and the Offering--Appraisals and
Realizable Value of Aircraft."

--------
(1) We have assumed the initial appraised value of each aircraft, determined as
    described under "--Secured Promissory Notes and the Aircraft," declines by
    3% per year for the first 15 years after the year of delivery of that
    aircraft and by 4% per year for the next 5 years. Other depreciation
    assumptions would result in important differences in the LTV ratios.
(2) The "pool balance" for the pass through trust or for the certificates
    indicates, as of any date, the portion of the original aggregate face
    amount of the certificates that has not been distributed to
    certificateholders. In calculating the outstanding pool balances, we have
    assumed that the pass through trust will acquire the maximum principal
    amount of secured promissory notes for all aircraft and that any principal
    amounts due on the Regular Distribution Dates have been paid.
(3) The LTV ratios for the certificates for each date were calculated by
    dividing (a) the expected outstanding pool balance by (b) the assumed value
    of all of the aircraft on that date based on the assumptions described
    above. The outstanding pool balances and LTV ratios may change if, among
    other things, the aggregate principal amount of the secured promissory
    notes acquired by the pass through trust is less than the maximum permitted
    under the terms of this offering, or the amortization of the secured
    promissory notes differs from the assumed amortization schedule calculated
    for purposes of this prospectus supplement.

                              Cash Flow Structure

    The following diagram illustrates the cash flow structure for payments
 on the certificates and on the secured promissory notes owned by the pass
 through trusts.



[Diagram omitted, which shows that we will pay to the loan trustee for leased
aircraft and owned aircraft (a) the lease rental payments, which are assigned by
the loan trustee, on leased aircraft and (b) the mortgage payments on owned
aircraft.  From those lease rental payments and mortgage payments, the loan
trustee will make secured promissory note payments on the series G secured
promissory notes with respect to all aircraft to the subordination agent.
Excess rental payments will be paid by the loan trustee to the lessors for
leased aircraft.  From those secured promissory note payments, the
subordination agent will pay principal, premium, if any, and interest to the
pass through trustee for the class G trust, which in turn will pay this
principal, premium, if any, and interest to the holders of class G
certificates.  The subordination agent may also receive advances, if any, and
pay reimbursements, if any, to the liquidity provider.  The subordination
agent may also receive policy drawings, if any, and pay reimbursements, if
any, to the policy provider.  The applicable depositary will make interest
payments on the deposits to the paying agent on behalf of the escrow agent.
From such interest payments, the paying agent on behalf of the escrow agent
will make payments to the holders of the class G certificates.


 --------
 (1) The Owner Trust will assign to the Loan Trustee its right to receive
     these payments and we will make these payments directly to the Loan
     Trustee.
 (2) Each aircraft leased to US Airways will be subject to a separate
     lease and a related indenture. Each owned aircraft will be subject to
     a separate indenture.
 (3) These payments from the liquidity facility cover up to three interest
     payments on the certificates of the pass through trust.
 (4) The policy covers payment of interest on and the outstanding balance
     of the certificates in the circumstances described in this prospectus
     supplement.
 (5) These payments will be made from payments on the secured promissory
     notes as supplemented by the liquidity facility and the financial
     guaranty insurance policy.
 (6) The proceeds of the public offering of the certificates initially
     will be held in escrow and deposited with the depositary. The
     depositary will hold such funds as interest-bearing deposits. The
     pass through trust will withdraw funds from the deposits to purchase
     the corresponding series of secured promissory notes from time to
     time as each aircraft is financed. The scheduled payments of interest
     on the secured promissory notes and on the deposits, taken together,
     will be sufficient to pay accrued interest on the outstanding
     certificates. The liquidity facility will not cover interest on the
     deposits. If any funds remain as deposits at the end of the delivery
     period, such funds will be withdrawn by the escrow agent and
     distributed to the holders of the certificates, together with accrued
     and unpaid interest thereon and a premium payable by US Airways,
     provided that no premium will be paid with respect to unused deposits
     attributable to the failure of an aircraft to be delivered prior to
     the end of the delivery period for any reason that was not caused by
     US Airways' fault or negligence.

Through Trustee.........  The pass through trustee will distribute all payments
                          of principal, premium, if any, and interest received
                          on the secured promissory notes held in the pass
                          through trust to the holders of the certificates.

                          The pass through trustee will distribute all
                          scheduled payments of principal and interest paid on
                          the secured promissory notes on regular distribution
                          dates.

                          The pass through trustee will distribute principal,
                          premium, if any, and interest received on the secured
                          promissory notes resulting from any early redemption
                          or purchase of those secured promissory notes on a
                          special distribution date. The pass through trustee
                          will also distribute any

                          premium that we pay in connection with the return of
                          any unused deposit. Such distribution of premium will
                          be on a special distribution date. The pass through
                          trustee will provide certificateholders with at least
                          15 days' notice prior to any special distribution.
                          Distributions by the subordination agent to the pass
                          through trustee for the benefit of the
                          certificateholders generally are subject to the
                          intercreditor agreement and subordination provisions
                          described below.

Distribution by the
Paying Agent............  The paying agent will distribute all payments of
                          interest on the deposits and any unused deposits
                          relating to the pass through trust to the holders of
                          the certificates.

Possible Issuance of
Class C Certificates....  Subject to certain conditions, we may elect to issue
                          series C secured promissory notes through the sale of
                          class C pass through trust certificates in connection
                          with the financing of any of the 20 aircraft
                          described in this prospectus supplement. The series C
                          secured promissory notes will be funded from sources
                          other than this offering and will be subordinated to
                          the series G secured promissory notes with respect to
                          the same aircraft financed by such series G secured
                          promissory notes. Any series C pass through trust
                          certificates will be issued by a newly organized pass
                          through trust and not the 2000-2G pass through trust.

                          If and when class C certificates are issued, any
                          distributions by the subordination agent to the class
                          C pass through trustee for the benefit of the class C
                          certificateholders will be subject to the
                          intercreditor provisions of the intercreditor
                          agreement described below.

                          It is a condition to the issuance of any class C
                          certificates that we receive written confirmation
                          from Standard & Poor's and Moody's that the issuance
                          of class C certificates will not result in a
                          withdrawal, suspension or downgrading of the rating
                          of the class G certificates (without regard to the
                          financial guaranty insurance policy).

                          If and when class C certificates are issued, they may
                          have the benefits of a liquidity facility, but will
                          not be entitled to the benefit of a financial
                          guaranty insurance policy.

Intercreditor             The class G pass through trustee, the subordination
Agreement...............  agent, the liquidity provider and the policy provider
                          will enter into an intercreditor agreement that
                          states how payments made on the secured promissory
                          notes, under the liquidity facilities and under the
                          insurance policy will be shared and distributed among
                          the class G pass through trustee, the liquidity
                          provider and the policy provider. The intercreditor
                          agreement also sets forth agreements among the pass
                          through trustee, the liquidity provider and the
                          policy provider relating to who will control the
                          exercise of remedies under the secured promissory
                          notes and the indentures. If class C certificates are
                          issued, the pass through trustee of the class C pass
                          through trust will become a party to the
                          Intercreditor Agreement.

                          There are no cross-default provisions in the
                          indentures or in the leases. This means that, if the
                          secured promissory notes relating to an aircraft are
                          in default and the secured promissory notes issued
                          with respect to the remaining aircraft are not in
                          default, no remedies will be exercisable with respect
                          to the remaining aircraft.

Subordination...........  Certain payments to the liquidity provider and to the
                          policy provider will be made prior to payments on all
                          or some of the certificates, as discussed under
                          "Description of the Intercreditor Agreement--Priority
                          of Distribution." If a junior class of certificates
                          are issued, the subordination provisions may permit
                          distributions to junior certificateholders after a
                          default on the secured promissory notes even if more
                          senior certificateholders have not been repaid in
                          full. The subordination provisions do not apply to
                          payments relating to the deposits or received from
                          the liquidity provider or the policy provider.

Control of Loan           As long as there is no continuing default under an
 Trustee................  indenture, the holders of a majority of the
                          outstanding principal amount of secured promissory
                          notes issued under that indenture (or the policy
                          provider under certain circumstances) will be
                          entitled to direct the loan trustee in taking action
                          under that indenture. If an indenture default is
                          continuing, the controlling party may direct the loan
                          trustee to exercise remedies, which may include
                          accelerating the secured promissory notes under that
                          indenture or foreclosing the lien on the aircraft
                          securing those secured promissory notes. In
                          exercising remedies during the nine months after the
                          earlier of (a) the acceleration of the secured
                          promissory notes issued under any indenture or (b)
                          our bankruptcy, the controlling party may not sell
                          the secured promissory notes or the aircraft subject
                          to the lien of that indenture for less than certain
                          specified minimums or modify lease rental payments
                          for that aircraft below a specified threshold.

                          The controlling party will be:

                          .  the policy provider, until the final distribution
                             of the aggregate outstanding balance of the
                             certificates, together with accrued and unpaid
                             interest, is made to the holders of the
                             certificates and no obligations owing to the
                             policy provider remain outstanding or,

                          .  if a policy provider default has occurred and is
                             continuing, then the pass through trustee, until
                             payment of final distributions to the holders of
                             the certificates, then

                          .  if any class C certificates are issued, the class
                             C pass through trustee.

                          Under certain circumstances, the liquidity provider
                          may elect to act as the controlling party, unless the
                          policy provider pays to the liquidity provider all
                          outstanding drawings, together with accrued interest
                          on such drawings, in which case, the policy provider
                          will be the controlling party (so long as no policy
                          provider default has occurred and is continuing). See
                          "Description of the Intercreditor Agreement--
                          Intercreditor Rights."

Right to Buy Class G
Certificates............  If class C certificates are issued, and we are in
                          bankruptcy or another triggering event has occurred,
                          the class C certificateholders, if any, will have the
                          right to purchase all of the class G certificates,
                          and whether or not any class C certificates are
                          issued or any such right is exercised, the policy
                          provider will thereafter have the right to purchase
                          all of the class G certificates. See "Description of
                          the Certificates--Purchase Rights of Potential Class
                          C Certificateholders and the Policy Provider."

                          The purchase price will be the outstanding balance of
                          the class G certificates plus accrued and unpaid
                          interest, plus any other amounts then due to the
                          class G certificateholders.

Liquidity Facility......  Under the liquidity facility for the pass through
                          trust, the liquidity provider will, if necessary,
                          make advances in an aggregate amount sufficient to
                          pay interest on up to three successive semiannual
                          regular distribution dates at the applicable interest
                          rate for the certificates. The liquidity facility may
                          not be used to pay any other amount relating to the
                          certificates and will not cover interest on deposits
                          held with the depositary.

                          The holders of the certificates to be issued by the
                          pass through trust will be entitled to receive and
                          keep the proceeds of advances under the liquidity
                          facility. This is because the subordination
                          provisions will not apply to the proceeds of advances
                          under the liquidity facility.

                          On receipt of each advance under the liquidity
                          facility, the subordination agent will, to the extent
                          of available funds, reimburse the liquidity provider
                          for the amount of that advance. That reimbursement
                          obligation and all interest, fees and other amounts
                          owing to the liquidity provider will rank senior to
                          the certificates in right of payment.

Insurance Policy          Under the insurance policy for the certificates, the
 Coverage...............  policy provider will honor drawings to cover:

                          .  any shortfall on any regular distribution date
                             (other than the final maturity date) in interest
                             on the certificates (and interest on the deposits
                             related to the escrow receipts attached to such
                             certificates) at the stated interest rate for the
                             certificates;

                          .  if a secured promissory note defaults in the
                             payment of principal or is accelerated, any
                             shortfall on any special distribution date between
                             (a) amounts actually available to the
                             subordination agent for distribution to the pass
                             through trustee from a disposition of that secured
                             promissory note or of its underlying collateral
                             and (b) the amount necessary for the subordination
                             agent to pay to the pass through trustee an amount
                             equal to the then outstanding principal amount of
                             that secured promissory note plus interest on that
                             amount
                             at the stated interest rate for the certificates
                             from the last regular distribution date to that
                             special distribution date;

                          .  if no payments on the certificates attributable to
                             the proceeds of the disposition of any secured
                             promissory note that has defaulted in the payment
                             of principal or has been accelerated (or the
                             disposition of its underlying collateral) are
                             received by the subordination agent for a period
                             of 18 months following the last date on which the
                             subordination agent received payment in full of
                             scheduled payments on that secured promissory
                             note, an amount equal to the then outstanding
                             principal amount of that secured promissory note
                             plus interest at the stated interest rate for the
                             certificates from the date of the last regular
                             distribution date to the special distribution date
                             on which such amounts are paid to the pass through
                             trustee; and

                          .  any shortfall on the final maturity date in the
                             final distribution (other than any unpaid premium)
                             on the certificates.

                          The policy provider has the right at the end of the
                          18-month period referred to above, so long as no
                          policy provider default has occurred and is
                          continuing, to elect instead:

                          .  to pay on the special distribution date an amount
                             equal to any shortfall in the scheduled principal
                             and interest that came due on the defaulted
                             secured promissory note (without regard to the
                             acceleration of the secured promissory note)
                             during the 18-month period (after giving effect to
                             the application of funds received from the
                             liquidity facility or the cash collateral account
                             attributable to that interest), and

                             distribution date to permit drawings under the
                             insurance policy for an amount equal to the
                             scheduled principal (without regard to any
                             acceleration thereof) and interest at the stated
                             interest rate for the certificates that were to
                             become due on the defaulted secured promissory
                             note on the related payment date until paid in
                             full.

                          After the policy provider has made such election, on
                          any business day that is a special distribution date
                          elected by the policy provider upon 20 days' notice
                          or, following either the occurrence and continuation
                          of a policy provider default or the sale or other
                          disposition of that secured promissory note or its
                          underlying collateral in connection with the exercise
                          of remedies, on any business day that is a special
                          distribution date specified by the subordination
                          agent upon 20 days' notice, in each case, the
                          subordination agent will make a policy drawing for an
                          amount equal to the then outstanding principal
                          balance of the defaulted secured promissory note and
                          accrued interest on the defaulted secured promissory
                          note at the stated interest rate for the certificates
                          from the last regular distribution date to that
                          special distribution date (after giving effect to the
                          application of funds, if any, received on that
                          special distribution date from the liquidity facility
                          or the cash collateral account attributable to
                          such interest) less any policy drawings previously
                          paid by the policy provider in respect of principal
                          on that secured promissory note.

                          In addition, regardless of whether the policy
                          provider makes the election, the policy provider
                          will, at the end of the 18-month period, endorse (if
                          not already endorsed) the insurance policy to provide
                          for the payment to the liquidity provider of interest
                          accruing on the liquidity obligations from and after
                          the end of the 18-month period as and when the
                          interest becomes due in accordance with the liquidity
                          facility.

                          Any shortfall in the amounts available to the
                          subordination agent for distribution to the holders
                          of the certificates will be calculated after the
                          application of available funds through the payment
                          priorities of the intercreditor agreement and of
                          funds received from the escrow agent, the liquidity
                          facility and the cash collateral account. The
                          insurance policy will cover only the class G
                          certificates (and interest only on the deposits
                          related to the escrow receipts attached to such
                          certificates), and will not cover any junior classes
                          of certificates, if any are issued. The proceeds of
                          any policy drawing, except as noted above, will be
                          applied only to the outstanding balance of, and
                          unpaid interest at the stated interest rate for, the
                          class G certificates (and interest on the deposits
                          related to the escrow receipts attached to such
                          certificates). The subordination agent will reimburse
                          the policy provider for any drawings, which
                          reimbursement obligation ranks junior to further
                          distributions on the class G certificates.

Escrowed Funds..........  Funds paid to the escrow agent by the
                          certificateholders will be deposited with a
                          depositary and held as deposits under a deposit
                          agreement for the pass through trust. Funds may be
                          withdrawn by the escrow agent at the direction of the
                          pass through trustee to purchase secured promissory
                          notes prior to the delivery period termination date.
                          On each regular distribution date, the depositary
                          will pay to the paying agent interest accrued on the
                          deposits relating to the pass through trust at a rate
                          equal to the interest rate for the certificates. The
                          paying agent, on behalf of the escrow agent, will pay
                          that interest to the certificateholders. The deposits
                          relating to the pass through trust and interest or
                          premium paid on or with respect to the related
                          deposits will not be subject to the subordination
                          provisions of the intercreditor agreement. Except as
                          noted in the next paragraph, the deposits cannot be
                          used to pay any other amount relating to the
                          certificates.

Unused Escrowed Funds...  We may not use all the deposits held in escrow prior
                          to the delivery period termination date. This may
                          happen because of delays in the delivery of aircraft
                          or other reasons. If any funds remain as deposits
                          with respect to the pass through trust after the
                          delivery period termination date, they will be
                          withdrawn by the escrow agent and distributed, with
                          accrued and unpaid interest, to the holders of escrow
                          receipts. The holders of escrow receipts will receive
                          at least 15 days' prior written notice of this
                          distribution. That distribution will also include a
                          premium payable by us, provided that no premium will
                          be paid on unused deposits attributable to the
                          failure of an aircraft to be delivered prior to the
                          delivery period termination date for any reason that
                          was not our fault or was not caused by our
                          negligence. See "Description of the Deposit
                          Agreements--Unused Deposits."

Obligation to Purchase
Secured Promissory        Under the note purchase agreement, the pass through
Notes...................  trustee will be obligated to purchase the series G
                          secured promissory notes issued for each aircraft.

                          We may enter into a leveraged lease financing or a
                          secured debt financing with respect to each aircraft
                          pursuant to forms of financing agreements attached to
                          the note purchase agreement.

                          In the case of a leased aircraft, the terms of the
                          financing agreements entered into may differ from the
                          forms of those agreements described in this
                          prospectus supplement because we or the owner
                          participant may request changes. However, under the
                          note purchase agreement, the terms of those financing
                          agreements must (a) contain mandatory document terms
                          that are included in the note purchase agreement with
                          only those modifications as are permitted by the note
                          purchase agreement and (b) not vary mandatory
                          economic terms that are included in the note purchase
                          agreement. In addition, we must (a) certify to the
                          pass through trustee and the policy provider that any
                          modifications to the forms of the financing
                          agreements do not materially and adversely affect the
                          certificateholders or the policy provider and (b) if
                          such agreements are modified in any material respect,
                          obtain prior written consent of the policy provider
                          and written confirmation from each rating agency that
                          the use of versions of agreements modified in any
                          material respect will not result in a withdrawal,
                          suspension or downgrading of the rating of the
                          certificates, without regard to the insurance policy.
                          The pass through trustee will not be obligated to
                          purchase secured promissory notes if, at the time of
                          issuance, we are in bankruptcy or certain other
                          specified events have occurred. See "Description of
                          the Certificates--Obligation to Purchase Secured
                          Promissory Notes."

Secured Promissory
Notes

   (a) Issuer...........  Leased Aircraft. Promissory notes secured by aircraft
                          leased by us will be issued by an owner trustee. We
                          expect that First Security Bank, National
                          Association, will be the owner trustee for all
                          aircraft that are leased to us under this prospectus
                          supplement. These secured promissory notes will not
                          be recourse to the owner trustee in its individual
                          capacity. We have an obligation to provide funds
                          under the related lease and related documents in
                          amounts sufficient to pay scheduled payments on those
                          secured promissory notes.

                          Owned Aircraft. We will be the issuer of promissory
                          notes secured by aircraft that we own.

   (b) Interest.........  The secured promissory notes held in the pass through
                          trust will accrue interest at the annual rate shown
                          on the cover page of this prospectus

                                      S-15
<PAGE>

                          supplement. Interest on the secured promissory notes
                          will be payable on February 5 and August 5 of each
                          year, commencing on August 5, 2000. Interest is
                          calculated on the basis of a 360-day year consisting
                          of twelve 30-day months.

   (c) Principal........  Principal payments on the secured promissory notes
                          are scheduled to be paid on February 5 and August 5
                          in scheduled years beginning on August 5, 2003.

  (d) Redemption and
    Purchase..........    Aircraft Event of Loss. If an aircraft under the
                          related financing agreements is lost, destroyed or
                          damaged beyond repair or other events of loss occur
                          with respect to an aircraft, all the secured
                          promissory notes issued for that aircraft will be
                          redeemed, unless we replace the aircraft under the
                          related financing agreements. This redemption price
                          will be the unpaid principal amount of those secured
                          promissory notes, together with accrued interest, but
                          without any premium.

                          Optional Redemption. The issuer of the secured
                          promissory notes for an aircraft may elect to redeem
                          the notes prior to maturity. This redemption price
                          will be the unpaid principal amount of those secured
                          promissory notes, together with accrued interest plus
                          a premium. See "Description of the Secured Promissory
                          Notes--Redemption."

                          Purchase by Owner. If an event of default under a
                          lease between us and an owner trustee occurs and is
                          continuing, the applicable owner trustee or owner
                          participant of an aircraft may elect to purchase all
                          the secured promissory notes with respect to that
                          aircraft, subject to the terms of the applicable
                          leased aircraft indenture. The purchase price will be
                          the unpaid principal amount of those secured
                          promissory notes, together with accrued interest, but
                          without any premium except under certain
                          circumstances specified in the relevant leased
                          aircraft indenture. In the case of an owned aircraft,
                          we will have no comparable right to purchase the
                          secured promissory notes.

   (e) Security.........  The secured promissory notes issued for each aircraft
                          will be secured by a security interest in that
                          aircraft and, in the case of each leased aircraft, in
                          the related owner trustee's rights under the lease
                          for that aircraft, subject to limited exceptions.

                          The secured promissory notes are not cross-
                          collateralized. This means that the secured
                          promissory notes issued for an aircraft will not be
                          secured by any other aircraft or lease. Any proceeds
                          from the sale of an aircraft or from the exercise of
                          other default remedies for an aircraft will not be
                          available to cover shortfalls with respect to any
                          other aircraft.

                          There are no cross-default provisions in the
                          indentures or in the leases. This means that if the
                          secured promissory notes issued for one aircraft are
                          in default and the secured promissory notes issued
                          for the remaining aircraft are not in default, no
                          remedies will be exercisable with respect to the
                          remaining aircraft.

Matters.................  U.S. federal income taxation. Each U.S. person
                          acquiring an interest in the certificates is required
                          to report on its federal income tax return its pro

                                  RISK FACTORS

   You should carefully read the following risk factors before purchasing any
certificates.

Risk Factors Relating to US Airways

 Leverage and Liquidity

   We have a higher proportion of debt compared to our equity capital than most
of our principal competitors. A majority of our property and equipment is
subject to liens securing indebtedness. We require substantial cash resources
in order to meet scheduled debt and lease payments and to finance day-to-day
operations. As a result, we may be less able than some of our competitors to
withstand a prolonged recession in the airline industry or respond as flexibly
to changing economic and competitive conditions.

   As of March 31, 2000, we had:

  .  $1.34 billion of cash, cash equivalents and short-term investments;

  .  a ratio of current assets to current liabilities of 0.79 to 1; and

  .  $2.86 billion of long-term debt and capital lease obligations.

   On December 10, 1999, we entered into a $250 million 364 day revolving
credit facility and a $250 million three-year revolving credit facility to
provide liquidity for our operations. The effective interest rate for borrowing
against the facilities is a floating rate based on the London Interbank Offered
Rate (LIBOR). As of March 31, 2000 we had drawn loan proceeds of $500 million
from these facilities, however, we have since then repaid the entire amount
drawn.

   Our ability to fulfill our short-term and long-term cash needs and to
service our debt obligations depends upon a variety of factors, including:

  .  the rates we pay to acquire resources vital to our operations, such as
     labor and aviation fuel;

  .  the prices we can obtain for our services;

  .  our ability to compete effectively in the market;

  .  the absence of adverse general economic changes;

  .  unit operating cost reductions; and

  .  our ability to attract new capital.

   We can give no assurances that any of these factors will produce an outcome
favorable to us. We continue to actively address our high cost structure. A
sustained reduction of unit cost is especially critical to us becoming more
competitive with airlines with lower unit operating costs and with those with
greater financial strength.

   Our parent has agreed to acquire up to 430 new Airbus aircraft, accompanying
jet engines and ancillary assets. As of June 30, 2000, we had taken delivery of
53 Airbus A320 family single-aisle aircraft and our parent had 101 Airbus A320
family single-aisle aircraft on firm order, 183 Airbus A320 family aircraft
subject to reconfirmation prior to delivery and options for 63 additional
Airbus A320 family aircraft. Of the A320 family aircraft on firm order, 37
aircraft are scheduled to be delivered during the balance of 2000 with the
remaining scheduled for delivery in 2001 to 2006, and 13 of the aircraft
scheduled for delivery between years 2002 to 2004 are subject to cancellation
with 18 months' notice and payment of a cancellation fee. We expect the new
single-aisle aircraft to replace certain aircraft that we operate. In addition,
as of June 30, 2000, we had taken delivery of five Airbus A330-300 aircraft and
our parent had five more on firm order and options for 20

                                      S-20
<PAGE>

additional Airbus widebody aircraft. Of the five firm order aircraft, two are
scheduled for delivery in the remainder of 2000, with the remaining scheduled
for delivery in 2001 to 2004. We expect to use the Airbus A330-300 aircraft
primarily in the transatlantic markets. As of March 31, 2000, the minimum
determinable payments associated with our parent's purchase agreements for
Airbus aircraft, including progress payments, payments at delivery, buyer-
furnished equipment, spares, capitalized interest, penalty payments,
cancellation fees and/or nonrefundable deposits, were estimated to be $1.85
billion for the nine months ended December 31, 2000, $1.14 billion in 2001,
$490 million in 2002, $290 million in 2003 and $504 million thereafter. Our
parent expects to assign substantially all of its rights and obligations with
respect to the purchase of the new Airbus aircraft to us.

   Our parent has entered into an agreement with CFM International, Inc. (CFM)
to purchase jet engines to power the A320 family aircraft. As part of the
agreement with CFM, an affiliate of CFM will maintain these engines under a
long-term renewable contract. Our parent has also reached an agreement in
principle with Pratt & Whitney to purchase jet engines to power the A330-300
aircraft and to provide long-term maintenance on those engines.

   We anticipate financing the acquisition of aircraft for which the purchase
rights have been assigned to us with a combination of enhanced pass through
trust certificates, other debt, leveraged leases and cash. To date, we have
used cash to purchase all of our new Airbus aircraft and completed leveraged
lease transactions or secured loan transactions for substantially all of such
aircraft soon after delivery. Because we are currently funding our parent's
purchase deposits for Airbus aircraft and because we expect our parent to
continue to assign its purchase rights to us, this financing will result in a
significant increase in our financial obligations. We currently have
commitments that we believe will provide financing for at least 25% of the
anticipated purchase price of all of our firm-order Airbus aircraft. However,
we need further financing or internally-generated funds to satisfy our capital
commitments for the balance of the aircraft purchase price and for other
aircraft-related expenditures. Other capital expenditures, such as purchases of
training simulators, aircraft parts and components, also are expected to
increase with the acquisition of the new aircraft and jet engines. There can be
no assurance that enough financing will be available for all aircraft and other
capital expenditures not covered by committed financing.

   We are currently unable to predict the full impact that the purchase of the
new aircraft will have on our future operating cash flows. We expect decreases
in some expenses as we replace several older, diverse aircraft types with
newer, more efficient aircraft. We are, however, experiencing increases in
certain expenses resulting from our growth plans, including higher ownership
costs. An economic downturn, additional government regulation, intensified
competition from lower-cost competitors or further increases in the cost of
aviation fuel or other resources vital to our operations could have a material
adverse effect on our results of operations, financial condition and future
prospects.

 Financial History

   We recorded a net loss of $211 million and net income of $67 million for the
three month periods ended March 31, 2000 and March 31, 1999, respectively. We
also recorded net income of $273 million for 1999, $559 million for 1998, $1.05
billion for 1997, $183 million for 1996 and $33 million for 1995. However, we
recorded net losses in excess of $3.2 billion on revenues of approximately
$35.9 billion from 1989 through 1994. Historically, the United States airline
industry's results have correlated with the performance of the economy. We are
unable to predict whether the favorable economic conditions of the last several
years will continue.

   In December 1999, the SEC issued Staff Accounting Bulletin No. 101, "Revenue
Recognition in Financial Statements" which provided guidance on the
recognition, presentation and disclosure of revenue in financial statements.
Although SAB 101 does not change existing accounting rules on revenue

principle. In the first quarter of 2000, we changed our method of accounting
for the sale of mileage credits in our Dividend Miles program from recognizing
revenue when credits are sold, to deferring a portion of revenue attributable
to future transportation and recognizing it as passenger revenue when the
service is provided. The remaining portion of sales proceeds will continue to
be recognized immediately as a component of other operating revenues. We
believe the new method results in a better matching of revenue with the period
in which travel services are provided. In connection with the change, we
recognized a $103 million, net of applicable income taxes, cumulative effect
charge on January 1, 2000.

   The major factors that influenced our financial performance for the first
quarter 2000 included significantly higher fuel prices, severe winter weather
along the eastern United States in January, reduced passenger traffic stemming
from the then-threatened March 25, 2000 shutdown and passenger apprehension of
flying on or around December 31, 1999 ("Y2K").

 Recent Financial Developments

   For the second quarter of 2000, we reported net income of $78 million and
operating income of $161 million on revenues of $2.4 billion. For the six
months ended June 30, 2000, we reported a net loss of $134 million and
operating income of $26 million on revenues of $4.5 billion. As noted above,
the results for the six months ended June 30, 2000 includes a $103 million
charge, net of applicable income taxes, for the cumulative effect of an
accounting change. Our financial performance for the second quarter of 2000 was
adversely affected by a number of factors including significantly higher fuel
prices, severe weather in June along the eastern United States and passenger
traffic losses due to lingering customer concerns over the then-threatened
March 25, 2000 shutdown. In addition, we continue to be under intense
competitive pressure from major carriers expanding into the East Coast region,
primarily with regional jets, as well as from low cost carriers. For additional
information, see our Current Report on Form 8-K filed with the SEC on July 19,
2000 and incorporated herein by reference in its entirety.

 Transactions with US Airways Group

   Historically, we have funded some of the activities and financing
transactions of our parent. As of March 31, 2000, our parent owed us $2.5
billion, of which $2.3 billion was not expected to be collected prior to March
31, 2001 including $2.0 billion classified as a component of stockholder's
equity. The advances primarily relate to our funding of our parent's common
stock purchase programs and for purchase deposit obligations for new flight
equipment. From January 1998, when our parent's first common stock purchase
program was authorized, through March 31, 2000, our parent had purchased a
total of 36.2 million shares of its common stock at a total cost of $1.9
billion.

 High Personnel Costs

   Our personnel costs are the largest single component of our operating costs
(approximately 37% for the three months ended March 31, 2000). Our unit
operating costs, including our personnel costs, generally are higher than those
of our competitors. We believe that we must substantially reduce our operating
cost structure to achieve sustained improved financial performance.

   In order to achieve those reduced costs, we have negotiated a series of
labor agreements based on a principle of parity. This approach provides wages
and benefits for our labor groups based on those of the same employee groups at
our four largest competitors, American Airlines, United Airlines, Northwest
Airlines and Delta Air Lines. While historically we have maintained labor
agreements which, as a whole, have been more costly than our competitors, these
parity agreements will bring our costs in line with our competitors while
providing comparable wages, benefits and work rules for our employees.

   We have achieved the following agreements with our principal labor groups:

  .  Pilots. Our pilots ratified a five year labor agreement in October 1997.
     The agreement became effective on January 1, 1998 and may be amended
     after January 1, 2003. The labor agreement

                                      S-22
<PAGE>

     includes various provisions that we believe will help address our high
     cost structure, including work rule changes and linking the compensation
     of our pilots to the compensation of pilots at several other major
     domestic air carriers. This contract also includes provisions that
     allowed us to launch our MetroJet service, our competitive response to
     low-cost, low-fare competition, and introduce regional jet aircraft on
     certain routes operated by US Airways Express.

  .  Flight Attendants. On May 1, 2000, our flight attendants, represented by
     the Association of Flight Attendants, approved a five-year labor
     contract. The contract is amendable on April 30, 2005.

  .  Fleet Service. Our fleet service employees, represented by the
     International Association of Machinists and Aerospace Workers, ratified
     an initial labor contract on April 1, 1999. The contract is amendable
     October 10, 2004.

  .  Mechanics. On October 6, 1999, our mechanics and related employees,
     represented by the International Association of Machinists and Aerospace
     Workers, ratified a new five year contract. The contract is amendable
     October 10, 2004.

  .  Passenger Service. Our passenger service employees voted to be
     represented by the Communications Workers of America on August 20, 1999
     following a court invalidation of the same union certification in May
     1999. On November 30, 1999 the membership ratified an initial agreement,
     which will first become amendable December 12, 2004.

  .  Other. Our flight dispatchers ratified a new collective bargaining
     agreement on July 29, 1999 covering approximately 198 flight
     dispatchers. The dispatchers' contract will become amendable January 31,
     2007. Our flight crew training instructors ratified a new collective
     bargaining agreement on May 3, 1999 covering approximately 152 flight
     crew training instructors. The contract is amendable May 3, 2004. Our
     simulator engineers rejected a tentative collective bargaining agreement
     on April 17, 2000. We reached another tentative agreement with this
     group of 57 employees on July 6, 2000 and we are awaiting membership
     ratification. A tentative agreement with The United Steel Workers
     covering the 106 Canadian customer service employees was ratified in
     January 2000 and became effective February 6, 2000. This contract will
     be amendable February 6, 2005.

 Geographical Concentration

   A substantial portion of our flights are to or from cities in the Eastern
United States. As of June 2000, approximately 82% of our departures were from,
and approximately 51% of our capacity, as measured by available seat miles,
was deployed within the United States east of the Mississippi River.
Accordingly, severe weather, downturns in the economy and air traffic control
problems in the Eastern United States adversely affect our results of
operations and financial condition more than they affect airlines that do not
have flights concentrated in the Eastern United States.

Risk Factors Relating to the Airline Industry

 General Industry Conditions

   The airline industry is highly competitive and susceptible to price
discounting and similar promotions. We believe that, for the foreseeable
future, demand for more profitable "business fares" will grow with the general
economy but demand for lower-profit "leisure fares," which are affected by the
general economy will remain highly price sensitive. These conditions will make
it difficult for airlines, including US Airways, to implement regular price
increases. Therefore, we believe we must reduce our cost structure in order to
ensure our long-term financial stability.

 Current Competitive Position

   Most of our operations are in competitive markets. We compete with at least
one major airline on most of our routes between major cities. We also compete
with all forms of ground transportation.

                                     S-23
<PAGE>

   Vigorous price competition exists in the airline industry. Competitors
frequently offer sharply reduced discount fares and other promotions to
increase the number of passengers during normally slack travel periods, to
generate cash flow and to increase market share in selected markets. We often
elect to match discount or promotional fares in certain markets in order to
compete in those discounted markets. We and our affiliates continue to
experience an increase in pricing pressures and competition.

 Significant Impact of Low-Cost, Low-Fare Competition

   Our foremost competitive threat is the growth of low-cost, low-fare
competition in our primary operating region, the Eastern United States. Our
primary low-cost, low-fare competition is Southwest Airlines and Delta Express.
Southwest Airlines has exhibited steady growth within the Eastern United States
since launching service at Baltimore-Washington International Airport in 1993.
In October 1996, Delta Air Lines, a major air carrier, which was itself
experiencing pressure from low-cost, low-fare competition, launched Delta
Express, its low-cost product.

   Direct competition with low-cost, low-fare competitors has typically
resulted in lower average revenue received for each mile a revenue passenger is
carried. Our Northeast United States to Florida service has been particularly
affected by low-cost, low-fare competition. We have the highest unit operating
cost, as measured by operating cost per available seat mile or cost per
available seat mile, of all major domestic air carriers. Our cost per available
seat mile was 13.39 cents for the first three months of 2000 and 12.75 cents
for the same period in 1999. In contrast, Southwest Airlines reported unit
operating costs of 7.68 cents and 7.33 cents for the corresponding periods in
2000 and 1999, respectively.

   We launched MetroJet, our competitive response to low-cost, low-fare
competition, on June 1, 1998. We believe that MetroJet is enabling us to
compete effectively against low-cost, low-fare competitors in the markets in
which MetroJet operates. We also believe that MetroJet improves the
attractiveness of our overall product line, particularly with respect to
predominately leisure markets such as service between the Northeast United
States and Florida.

 Aviation Fuel

   Aviation fuel costs represent a significant portion of our operating costs.
These costs were approximately 8% of our operating costs for 1999 and 12% of
our operating costs for the six months ended June 30, 2000. Aviation fuel costs
increased significantly in the first six months of 2000 due primarily to
average fuel prices increasing 81.5% over their prior year level. Significant
increases in aviation fuel costs could materially and adversely affect our
results of operations. Fuel prices continue to be susceptible to, among other
factors, political events and market factors that we cannot control. If a fuel
supply shortage resulting from a disruption of oil imports or other factors
occurs, higher fuel prices or curtailment of scheduled service could result.
Aviation fuel expenses increased approximately 92% during the six months ended
June 30, 2000 versus the six months ended June 30, 1999 and are expected to
continue to remain high for the remainder of 2000.

 Regulatory Matters

   We are subject to a wide range of government regulation. Changes in
government regulation can have a material impact on our results of operations
and financial condition. In recent years, for example, the Federal Aviation
Administration ("FAA") has issued or proposed mandates relating to, among other
things:

  .  flight data recorders that measure more parameters than most original
     equipment flight data recorders;

  .  cargo hold fire detection/suppression systems;

  .  ground proximity warning systems;

  .  the retirement of older aircraft;

                                      S-24
<PAGE>

  .  collision avoidance systems;

  .  airborne windshear avoidance systems;

  .  noise abatement; and

  .  increased inspections and maintenance procedures to be conducted on
     certain aircraft.

   We expect to continue to incur expenditures relating to compliance with
aging aircraft modifications and safety. In addition, several airports have
increased substantially the rates charged to airlines. The ability of airlines
to contest these increases is restricted by federal legislation, United States
Department of Transportation ("DOT") regulations and judicial decisions.

   The FAA has designated John F. Kennedy International Airport, Chicago O'Hare
International Airport, LaGuardia Airport and Washington's Ronald Reagan
Washington National Airport as "high-density traffic airports" and limited the
number of departure and arrival slots available to air carriers at those
airports. In April 2000, legislation was enacted which eliminates slot
restrictions beginning in 2001 at O'Hare and in 2007 at LaGuardia and Kennedy.

   Among other things, this legislation encourages the development of air
service to smaller communities from slot-controlled airports. In connection
with this, we have begun implementing a plan to increase service to such
communities from LaGuardia. In addition, several airlines have announced
increased regional jet service from LaGuardia to cities in the East, South and
Midwest which are currently served by us. We cannot predict the outcome of
those announced plans.

   Regional jet aircraft add a great deal of flexibility to our system because
they can operate effectively in markets too small for our larger jet service
and with stage lengths too great for turboprop aircraft. The number of regional
jet aircraft we can operate is limited by provisions in our pilot labor
contract. In April 2000, our pilots ratified an agreement whereby we can
increase the number of regional jet aircraft operated from 35 to approximately
70. We are currently evaluating where and when we will deploy the additional
aircraft.

   Legislation has been enacted that provides for increased review of airline
joint ventures by the DOT. In April 1998, the DOT issued proposed rules
designed to regulate perceived anti-competitive behavior directed at new
entrants in the airline industry. Legislation was enacted requiring, among
other things, the National Research Council of the National Academy of Sciences
to complete a comprehensive study pertaining to competitive issues in the
airline industry prior to the DOT's implementation of those rules. This study
has been completed. We cannot predict whether or when any proposed rules will
be adopted.

   Working with members of Congress, Air Transport Association members
developed a voluntary Airline Customer Service Commitment, which was announced
in June 1999. As a result of this commitment, members of Congress agreed not to
pursue various consumer-oriented legislative proposals at this time. In return,
U.S. air carriers agreed voluntarily to publish and implement plans to address
consumer concerns in a variety of areas. We implemented our customer service
commitment plan on December 15, 1999.

   We cannot predict what laws and regulations will be adopted, what changes to
aviation treaties and agreements between the United States and foreign
governments may be affected or how we might be affected by any of the
foregoing. We may be adversely affected by future laws or regulations.

Risk Factors Relating to the Certificates and the Offering

 Appraisals and Realizable Value of Aircraft

   Three independent appraisal and consulting firms have prepared base value
appraisals of the aircraft. Letters summarizing these appraisals are attached
to this prospectus supplement as Appendix I. These appraisals, which are based
on the base value of the aircraft, rely on assumptions and methodologies and
may

                                      S-25
<PAGE>

not reflect current market conditions that could affect the fair market value
of the aircraft. Base value is the theoretical value for an aircraft that
assumes a balanced market, while current market value is the value for an
aircraft in the actual market. The appraisals were prepared without physical
inspection of the aircraft. Appraisals based on other assumptions and
methodologies may result in valuations that are materially different from those
contained in the appraisals. See "Description of the Aircraft and the
Appraisals--The Appraisals."

   An appraisal is only an estimate of value. It does not indicate the price at
which an aircraft may be purchased from the aircraft manufacturer or the price
at which an aircraft may be sold in connection with the exercise of remedies
under any indenture. Therefore, the appraisal should not be relied upon as a
measure of the actual sales value of the aircraft. The proceeds realized upon a
sale of any aircraft may be less than its appraised value. In particular, the
appraisals of the aircraft to be delivered after the date of this prospectus
supplement are estimates of values as of future delivery dates. The value of an
aircraft, if remedies are exercised under the applicable indenture, will depend
on market and economic conditions, the supply of similar aircraft, the
availability of buyers, the condition of the aircraft and other factors. As a
result, aircraft sale proceeds on any exercise of remedies may not be enough to
pay the total amount due on the certificates.

 Control Over Collateral; Sale of Collateral

   If a default under an indenture is continuing, the controlling party may
direct the loan trustee under that indenture to exercise remedies under that
indenture. The controlling party will be:

  .  the policy provider, until the final distribution of the aggregate
     outstanding balance of the certificates, together with accrued and
     unpaid interest, is made to the holders of the certificates and no
     obligations owing to the policy provider remain outstanding or,

  .  if a default has occurred and is continuing with respect to the policy
     provider, the pass through trustee, then;

  .  if any class C certificates are issued, the class C pass through
     trustee.

   Remedies exercisable under an indenture may include accelerating the
applicable secured promissory notes under the indenture or foreclosing the lien
on the aircraft securing those secured promissory notes. See "Description of
the Certificates--Indenture Defaults and Certain Rights Upon an Indenture
Default."

   Under certain circumstances, the liquidity provider may elect to act as the
controlling party, unless the policy provider pays to the liquidity provider
all outstanding drawings, together with accrued interest on such drawings, in
which case, the policy provider will be the controlling party (so long as no
policy provider default has occurred and is continuing). See "Description of
the Intercreditor Agreement--Intercreditor Rights." If multiple liquidity
providers exist, the liquidity provider with the larger amount owed to it will
be entitled to make the election in the immediately preceding sentence.

   During the continuation of any indenture default, the controlling party may
accelerate and sell the secured promissory notes issued under that indenture,
subject to certain limitations. See "Description of the Intercreditor
Agreement--Intercreditor Rights--Sale of Secured Promissory Notes or Aircraft."
The market for secured promissory notes during any indenture default may be
very limited, and there can be no assurance as to the price at which they could
be sold. If the controlling party sells any secured promissory notes for less
than their outstanding principal amount, certificateholders may receive a
smaller, amount of principal distributions than expected and will not have any
claim for the shortfall against us, any owner trustee, any owner participant,
the liquidity provider, the policy provider (except as provided in the
insurance policy) or the pass through trustee.

 Ratings of the Certificates

   It is a condition to the issuance of the class G certificates that they
receive a rating of at least Aaa from Moody's and AAA from Standard & Poor's.

                                      S-26
<PAGE>

   A rating is not a recommendation to purchase, hold or sell certificates,
because that rating does not address market price or suitability for a
particular investor. A rating may not remain for any given period of time and
may be lowered or withdrawn entirely by a rating agency if at any time, in its
judgment, circumstances in the future, including the downgrading of us, the
depositary, the policy provider or the liquidity provider, so warrant.

   The expected rating of the certificates will be based primarily on the
default risk of the secured promissory notes purchased by the pass through
trust, the rating of the policy provider, the rating of the depositary, the
availability of the liquidity facility for the benefit of holders of the
certificates, the availability of the insurance policy and the collateral value
provided by the aircraft relating to the secured promissory notes. Standard &
Poor's has indicated that its rating will apply to a unit consisting of
certificates representing the trust property and escrow receipts initially
representing beneficial interests in certain rights to $362,414,000 of deposits
under the escrow agreement. Amounts deposited under the escrow agreement are
not our property and are not entitled to the benefits of Section 1110 of the
U.S. Bankruptcy Code. Neither the certificates nor the escrow receipts may be
separately assigned or transferred. The reduction, suspension or withdrawal of
the ratings of the certificates will not, by itself, constitute an event of
default.

 Agreements May Change

   The actual participation agreements, leases and leased aircraft indentures
that we enter into may differ from the descriptions of these agreements in this
prospectus supplement because we or the owner participant may request changes.
The degree to which these agreements may change is limited because:

  .  the agreements are required to contain certain mandatory document terms
     and mandatory economic terms, described in this prospectus supplement
     under the heading "Description of the Certificates-- Obligations to
     Purchase Secured Promissory Notes";

  .  we must certify to the policy provider and the pass through trustee that
     changes to the form agreements do not materially and adversely affect
     the certificateholders or the policy provider; and

  .  if we use forms of financing agreements that are modified in any
     material respect from forms attached to the note purchase agreement or
     otherwise approved by the rating agencies, we are obligated to obtain
     the written consent of the policy provider and written confirmation from
     the rating agencies that the use of those versions of agreements will
     not result in a withdrawal, downgrade or suspension of the rating of the
     certificates (without regard to the insurance policy).

 Unused Escrowed Funds

   We may not use all of the deposits held in escrow prior to the delivery
period termination date. See "Description of the Deposit Agreements--Unused
Deposits." If any funds remain as deposits with respect to the pass through
trust after the delivery period termination date, those remaining funds will be
withdrawn by the escrow agent and distributed, with accrued and unpaid
interest, to the certificateholders. In addition, we will pay a premium with
respect to those remaining deposits, except for any deposits that are returned
because an aircraft is not delivered prior to the delivery period termination
date for any reason that is not our fault or caused by our negligence. See
"Description of the Deposit Agreement--Unused Deposits."

 Limited Market for Resales of the Certificates

   Prior to the offering of the certificates, the certificates were not
publicly traded. Neither we nor the pass through trust intends to apply for
listing of the certificates on any securities exchange or otherwise. We have
been advised by the underwriters that they presently intend to make a market in
the certificates, as permitted by applicable laws and regulations, after
consummation of the offering of the certificates. None of the underwriters is
obligated, however, to make a market in the certificates and any market-making
activity may be discontinued at any time without notice at the sole discretion
of each underwriter. There can be no assurance that an active public market for
the certificates will develop or that an investment in these certificates will
be liquid.

<PAGE>

Risk Factors Relating to the Policy Provider

 The Impact of any Decline in the Financial Condition of the Policy Provider

   The expected AAA rating by Standard & Poor's and the Aaa rating by Moody's
of the certificates will be based, primarily, on the existence of the insurance
policy insuring the complete and timely payment of interest accrued and payable
on the certificates on each regular scheduled date for the payment of interest
and the payment of principal on or (under certain circumstances) before the
date on which the certificates mature. Any decline in the financial condition
of the policy provider or the insolvency of the policy provider may result in
the downgrade of the foregoing ratings of the certificates and may impair the
ability of the policy provider to make payments to the holders of the
certificates under the terms of the insurance policy. In addition, in the event
of insolvency of the policy provider under insurance insolvency proceedings, it
is possible that the subordination agent would be unable to recover the full
amount due under the certificates on its unsecured claim against the policy
provider. For information on the financial information generally available with
respect to the policy provider, see "Description of the Policy Provider" and
"Description of the Policy and the Policy Provider Agreement--The Policy."

 The Limited Nature of the Policy

   The insurance policy's support on interest payments and principal payments
will be limited to the certificates and interest on the deposits related to the
escrow receipts attached to such certificates. Although drawings under the
insurance policy for interest payments may be made when interest is due,
drawings for principal payments may not, except in certain circumstances, be
made until the final maturity date for the certificates. The insurance policy
will not provide coverage for any junior classes of certificates, if any are
issued.

 The Policy Provider as a Controlling Party

   Unless certain events of default have occurred with respect to the policy
provider, the policy provider will be the controlling party, unless the
liquidity provider has elected to become the controlling party as described in
"Description of the Intercreditor Agreement--Intercreditor Rights--Controlling
Party." As the controlling party, the policy provider has the ability, subject
to certain limitations, to direct the subordination agent to exercise any
remedy, including the ability to direct the subordination agent to sell any or
all of the secured promissory notes or to instruct the loan trustee under an
indenture to accelerate the secured promissory notes issued under such
indenture and to foreclose upon the lien created under the indenture.

                           FORWARD-LOOKING STATEMENTS

   This prospectus supplement and the information incorporated by reference
into this prospectus supplement include forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995. We prepare
forward-looking statements using estimates of future revenues, expenses,
activity levels and economic and market conditions, many of which are outside
of our control. These forward-looking statements involve risks, uncertainties
and other factors that may cause our actual results to differ materially from
the results we discuss in the forward-looking statements. These risks,
uncertainties and other factors include, among others:

  .  economic conditions;

  .  labor costs;

  .  financing costs;

  .  aviation fuel costs;

  .  the anticipated merger of our parent and a subsidiary of UAL
     Corporation;

  .  competitive pressures on pricing--particularly from lower-cost
     competitors;

  .  weather conditions;

  .  governmental legislation;

  .  consumer perceptions of our products;

  .  demand for air transportation in the markets in which we operate;

  .  other operational matters discussed in this prospectus supplement; and

  .  other risks and uncertainties listed from time to time in reports we
     periodically file with the SEC.

   The preparation of forward-looking statements also involves other factors
and assumptions not listed above. If the assumptions used to prepare the

                                   US AIRWAYS

   We are a certificated air carrier engaged primarily in the business of
transporting passengers, property and mail. We are the principal operating
subsidiary of our parent, accounting for approximately 88% of our parent's
consolidated operating revenues for 1999.

   We carried approximately 56 million passengers in 1999 and currently rank as
the sixth largest domestic air carrier, as ranked by total revenue passenger
miles, based on our review and analysis of our and other airline press
releases. Eight air carriers that operate under the trade name "US Airways
Express" code share with us. Under a code share arrangement, one carrier places
its designator code and sells tickets on flights of another carrier. Our
combined system served 205 destinations worldwide as of June 30, 2000. As of
June 30, 2000, we had approximately 42,650 full-time equivalent employees.

   We have established a foundation on which we are moving forward with
achieving our long-term strategic objective of establishing our self as a
competitive global airline:

  .  a series of labor agreements providing wages and benefits based on those
     of the same employee groups at our largest competitors;

  .  agreements between our parent and an affiliate of Airbus Industrie,
     G.I.E. to purchase up to 400 new aircraft from the Airbus A320 family of
     single-aisle aircraft, which aircraft are expected to replace certain
     older aircraft that we or our parent's other subsidiaries operate and up
     to 30 Airbus widebody aircraft, which we expect to use primarily in
     transatlantic markets;

  .  an expanded and substantially improved line of products including new
     international service and international first class and additional
     regional jet service on certain routes operated by US Airways Express;

  .  MetroJet service--our competitive response to low-cost, low-fare
     competition; and

  .  a contract with Sabre, Inc. that we believe will provide enhancements to
     our information services requirements.

Merger

   US Airways Group, Inc., our parent corporation, has entered into an
Agreement and Plan of Merger with UAL Corporation, United Airlines' parent
corporation, and Yellow Jacket Acquisition Corp., a wholly owned subsidiary of
UAL which has been formed for the purpose of this merger, pursuant to which the
merger subsidiary will be merged into US Airways Group. As a result, US Airways
Group would be the surviving corporation and would become a wholly owned
subsidiary of UAL, and we would continue to be a wholly owned subsidiary of US
Airways Group. Under this structure, UAL would not be obligated to assume any
of our obligations under the leases, Participation Agreements, Indentures, pass
through trust agreements, or any other obligations which we have with respect
to the secured promissory notes.

   Consummation of the merger is subject to various conditions set forth in the
Agreement and Plan of Merger, including, but not limited to, the receipt of
regulatory approvals and approval by the stockholders of US Airways Group. At
this time, we cannot predict the outcome of the regulatory and other approvals
necessary for the consummation of the merger, nor can we predict what effect,
if any, the merger might have on us or our operations. In addition, if the
merger is consummated, our relationships with certain of our major vendors and
partnerships, including Airbus Industrie, American Airlines, CFM International,
Inc., Chautauqua Airlines, Mesa Airlines, Pratt & Whitney, and Sabre Inc., may
be affected. We cannot predict at this time the effect of the merger on our
relationships with vendors and partners.

   If the merger between our parent and a subsidiary of UAL Corporation is
consummated, the combined company may be required to divest some of its routes
and slots for competitive reasons. To address the

                                      S-30
<PAGE>

potential competitive issues, the companies have entered into a Memorandum of
Understanding with Robert Johnson, under which Mr. Johnson would buy certain
assets from us and create a new airline to operate out of Reagan National
Airport. We would retain the routes formerly operated by US Airways Shuttle and
the assets necessary to fly to our hubs at Pittsburgh, Charlotte and
Philadelphia.

US Airways Shuttle

   Effective July 1, 2000, Shuttle, Inc., a wholly owned subsidiary of our
parent, was merged into us. We now operate Shuttle Inc.'s former service
between LaGuardia and Logan International Airport and LaGuardia and Reagan
National Airport.

Domestic Service

   Our major connecting hubs are located at airports in Charlotte, Philadelphia
and Pittsburgh. We also have substantial operations at Boston's Logan
International Airport, LaGuardia and Reagan National Airport. As of January
2000, as measured by departures, we were the largest airline at each of these
airports and are the largest air carrier in many other smaller eastern cities
such as Albany, Buffalo, Hartford, Richmond, Rochester and Syracuse based on
information provided by OAG Worldwide, a division of Reed Business Information.
We also are the leading airline from the Northeast United States to Florida,
based on information provided by OAG Worldwide. As of January 2000,
approximately 85% of our departures were from, and approximately 57% of our
capacity as measured by available seat miles was deployed within the United
States east of the Mississippi River.

   Four Northeast United States corridor cities are the core of our network:
Boston, New York, Philadelphia and Washington. With the exception of Newark
Airport and Washington Dulles Airport, we are the number one carrier in terms
of number of departures at these metro regions' airports as of January 2000. We
believe that our intra-East Coast core provides a platform for growth by
allowing us to leverage our intra-East Coast short-haul presence into long-haul
operations.

 MetroJet

   In response to the entrance and growth of "low-cost, low-fare" competition,
including competition from Southwest Airlines and Delta Express, we launched
our "MetroJet" brand on June 1, 1998.

   MetroJet is designed to be competitive with Southwest Airlines in terms of
labor costs, asset utilization and on-board product offered. Southwest Airlines
still maintains advantages relating to the cost of employee benefits,
productivity and distribution, but we believe that these advantages have been
significantly reduced. We believe MetroJet will maintain a revenue premium
advantage over Southwest Airlines by virtue of the following factors:

  .  strong East Coast presence;

  .  broad-based Dividend Miles program;

  .  advance seat assignments;

  .  existing customer base;

  .  vast travel agency network;

  .  reciprocal club room access for members of US Airways Clubs and American
     Airlines' Admirals Club; and

  .  a marketing agreement with American Airlines to share frequent flyer
     miles.

   Due to these factors, we also anticipate carrying more passengers per
departure than our low-cost competitors, as well as a broader yield mix of
passengers. See "The US Airways and American Airlines Marketing Relationship."

                                      S-31
<PAGE>

   We believe we are realizing cost savings from MetroJet due to increased
asset utilization and labor costs that are significantly below that of our
other operations principally due to the fact that the MetroJet service is
largely a conversion of our other services. As of June 30, 2000, MetroJet
operated 38 aircraft. We anticipate holding MetroJet's capacity at the current
level for the next few quarters.

Expanding International Service

   We continue to expand international service. A majority of transatlantic
passengers originate their travel from the eastern United States, which is our
primary operating region. We began to bolster international operations to take
advantage of our strategic position in 1996. In March 2000, we took delivery of
our first A330-300 widebody aircraft. The new Airbus A330 aircraft play an
important role in our long-term strategy of establishing ourselves as a
competitive global airline. We launched our three-class transatlantic service
when the A330-300 was placed into service on May 4, 2000 operating between
Philadelphia and Paris. A premium First Class cabin was added to an expanded
Envoy Class service and an Economy Class cabin.

   Since the end of 1999, we have added service between Charlotte and both
Paris and Frankfurt on April 13, 2000 and May 11, 2000, respectively. In
addition, we added service between Philadelphia and Manchester, England on May
25, 2000. In April 2000, we received approval from the DOT to operate daily
nonstop flights between Pittsburgh and London's Gatwick Airport. This service
was started on July 17, 2000. Our transatlantic available seat miles in 1999
were 21% greater than for 1998. We will continue to explore additional
international opportunities.

   In addition, during the summer of 2000, we announced and received the
necessary regulatory authority for expanded service to the Caribbean, involving
new service to Aruba and the Dominican Republic and expanded service to Cancun,
Mexico and Bermuda. These services are scheduled to commence in November 2000.

Code Sharing Relationships

   Eight air carriers that operate under the trade name "US Airways Express,"
including our parent's wholly-owned subsidiaries Allegheny Airlines, Piedmont
Airlines and PSA Airlines, have code sharing arrangements with us. Typically,
under a code share arrangement, one air carrier places its designator code and
sells tickets on flights of another carrier. Through service agreements, we
provide reservations and, at certain stations, ground support services, in
return for service fees. The US Airways Express network feeds traffic into our
route system at several points, primarily at our hubs. As of January 1, 2000,
US Airways Express served 174 airports in the continental United States, Canada
and the Bahamas, including 74 airports that we also serve. In 1999, US Airways
Express air carriers carried approximately 11 million passengers, approximately
58% of whom connected to our flights. We also have code-share arrangements with
Deutsche BA for certain intra-Germany flights.

The US Airways and American Airlines Marketing Relationship

   On April 23, 1998, we and American Airlines announced a marketing
relationship that gives customers of both companies important new benefits,
including combined access to both frequent traveler programs: our Dividend
Miles and American Airlines' AAdvantage. Under the program, effective August 1,
1998, members who belong to Dividend Miles and AAdvantage are able to claim
awards for travel on both airlines. In addition, US Airways Club and American
Airlines' Admirals Club members now enjoy reciprocal access to each airlines'
airport clubs. During August 1998, the second phase of the marketing
relationship was launched: enabling Dividend Miles and AAdvantage members who
belong to both programs to combine miles when claiming a travel award on either
airline. We cannot predict at this time the effect of the merger between our
parent and UAL Corporation on our relationship with American Airlines.

Fleet Rationalization and the Airbus Aircraft

   We are committed to rationalizing our fleet through our parent's order for
up to 400 new aircraft from the Airbus A320 family of single-aisle aircraft and
our parent's order for up to 30 new Airbus widebody aircraft. Prior to taking
delivery of any new Airbus aircraft, our operating fleet consisted of eight
different aircraft models--six within the 95-150 seat range--a diversity that
reflects the different airlines that have merged with or been acquired by us
over the years. The complexity of, and mechanical differences in, our fleet
create inefficiencies with respect to aircraft maintenance, flight scheduling,
flight crew and maintenance training and inventory management (spare parts).

   As of June 30, 2000, we had received 53 A320 family aircraft and five A330
aircraft into our fleet. The Airbus aircraft are more fuel efficient, are less
costly to maintain, have greater range capabilities and provide certain
customer service advantages over the aircraft they replace. For the year 2000,
we are scheduled to take delivery of 50 Airbus A320 family aircraft and seven
A330 aircraft and retire 17 B737-200 aircraft, four B727-200 aircraft and 13
DC-9 aircraft.

   We believe the addition of the Airbus A320 family of aircraft to our fleet
will allow us to enjoy economies of consolidation in terms of training costs,
ground support equipment and spare aircraft parts. We expect the Airbus
aircraft to serve the dual purposes of retiring older fleet types while growing
the fleet overall. We expect the Airbus aircraft to give us the flexibility to
further increase capacity through the exercise of options for additional
aircraft. The addition of the Airbus single-aisle aircraft also provides more
seats with lower direct operating costs per plane mile. As we modernize our
fleet over the next several years, we believe we will realize a reduction in
maintenance and fuel costs associated with retiring aircraft. A newer fleet is
generally expected to have greater dispatch reliability, which is expected to
enhance further our revenues. However, we have experienced and will continue to
experience increases in certain ownership costs such as interest expense,
depreciation and aircraft rent expense in conjunction with the higher ownership
and/or rental costs associated with the new aircraft. We also are experiencing
increases in certain expenses which are associated in part with the integration
of new Airbus aircraft into our fleet, which have adversely affected our
financial performance.

   We also believe that upgrading our fleet to include the Airbus A320 family
of aircraft will provide us with added flexibility in assigning aircraft to
routes based on customer volume and demand. As the full-passenger ranges of the
Airbus A320 family of aircraft range from 2,500 to 2,900 nautical miles, these
aircraft can be dispatched non-stop from any of our three domestic hub cities
to most major cities on the West Coast. Additionally, the Airbus A320-200
aircraft will be overwater equipped and have the range for Caribbean flying.

   Our parent's order for up to 30 Airbus widebody aircraft is designed to take
advantage of fleet commonality in order to increase our savings, in addition to
providing certain customer service benefits. We expect to use these aircraft
primarily in transatlantic markets. The savings in training costs, ground
support equipment and spare parts will be compounded because the Airbus
widebody aircraft are consistent in cockpit design with the Airbus A320 family
aircraft. The decision to select the Airbus A330-300 was based, in part, on the
desire to obtain properly-sized planes in order to upgrade existing routes as
well as to introduce service in new markets. We anticipate that, by combining
the Airbus widebody deliveries with the Airbus A320 family deliveries, we will
have one of the most modern commercial air carrier fleets within a few years
time. We also believe that the Airbus A330-300 offers exceptional passenger
appeal together with comfort and efficiency in international service.

US Airways' Market Position

   Historically, demand for air transportation has tended to mirror general
economic conditions. Since early 1995, general domestic economic conditions
have been relatively favorable with the level of demand for air transportation
exhibiting a strong correlation. In addition, over the same time period, we and
our affiliated carriers have experienced favorable pricing and capacity trends
in the markets in which we and our affiliated

                                      S-33
<PAGE>

carriers operate as a result of these economic conditions. However, recently we
have experienced an increase in pricing pressures from our competitors.

   Most of the markets in which we and our affiliated carriers operate are
highly competitive, especially with respect to leisure traffic. Crucial to our
ability to compete effectively is our ongoing effort to reduce our
traditionally high cost structure. We expect the Airbus single-aisle aircraft
to bring substantial operational cost savings to us over time. In addition, we
have developed our own cost-effective response to the low-cost, low-fare
competition by launching our MetroJet service.

Sabre, Inc. Agreement

   We entered into an extensive contract with Sabre, Inc. under which Sabre,
Inc. assumed responsibility, as of January 1, 1998, for substantially all our
information technology requirements. We expect the agreement with Sabre, Inc.
to result in substantial information system enhancements and efficiencies,
particularly in the areas of reservations, passenger check-in, yield management
and aircraft and crew scheduling.

On-Line Reservation System

   In March 2000, we launched an updated on-line Internet reservations system.
Our "www.usairways.com" offers customers a convenient way to search for low
fares and make reservations for flights in our system and for flights on
MetroJet and US Airways Express, as well as reserve cars with over 50 different
car rental agencies and rooms in 45,000 different hotels. Visitors to
"usairways.com" can manage their Dividend Miles accounts, check flight status,
obtain flight schedules, view ticket prices and check fare availability.

Legal Proceedings

   We are involved in legal proceedings arising out of an aircraft accident in
September 1994 near Pittsburgh in which 127 passengers and five crew members
lost their lives. With respect to this accident, the National Transportation
Safety Board held hearings in January and November 1995, and held a final
hearing in March 1999, at which it issued the final accident investigation
report. The report concluded that the probable cause of the accident involved a
malfunction of the aircraft's rudder system. All wrongful death cases have been
resolved except for three cases currently pending before the respective Federal
District Courts. We are fully insured with respect to this litigation and,
therefore, believe that the litigation will not have a material adverse effect
on our financial condition or results of operations.

   In May 1995, we, our parent, and the Retirement Income Plan for Pilots of US
Airways, Inc. were sued in federal district court for the District of Columbia
by 481 active and retired pilots alleging that defendants had incorrectly
interpreted the plan provisions and erroneously calculated benefits under the
plan. The plaintiffs sought damages in excess of $70 million. In May 1996, the
court issued a decision granting our motion to dismiss the majority of the
complaint for lack of jurisdiction, deciding that the dispute must be resolved
through the arbitration process under the Railway Labor Act because the plan
was collectively bargained. The plaintiffs appealed the district court's
dismissal and in February 1999, the U.S. Court of Appeals upheld the district
court's decision originally granted in May 1996 in our favor. In May 1999, the
plaintiffs filed a petition for certiorari with the U.S. Supreme Court. In
October 1999, the U.S. Supreme Court denied the plaintiffs' petition for
certiorari. The U.S. District Court has retained jurisdiction over one count of
the complaint alleging violation of a disclosure requirement under ERISA. We
believe there are no significant penalties likely to result from this
disclosure claim pending before the court. Recently, the plaintiffs have filed
a claim before the US Airways Pilot Retirement Board requesting arbitration of
their claim for benefits which they believe were erroneously calculated.

   In October 1995, we terminated for cause an agreement with In-Flight Phone
Corporation (IFPC). IFPC was our provider of on-board telephone and interactive
data systems. The IFPC system had been installed in approximately 80 aircraft
prior to the date of termination of the agreement. On December 6, 1995, IFPC
filed

                                      S-34
<PAGE>

suit against us in Illinois state court seeking equitable relief and damages in
excess of $186 million. We believe that our termination of this agreement was
appropriate and that we are owed significant damages by IFPC. We have filed a
counterclaim against IFPC seeking compensatory damages in excess of $25 million
and punitive damages in excess of $25 million. In January 1997, IFPC filed for
protection from its creditors under Chapter 11 of the Bankruptcy Code. The
parties stipulated to lift the automatic stay provided for in the Bankruptcy
Code, which would allow the claims to be fully litigated. At the present time,
we are engaged in written discovery. We are unable to predict at this time the
ultimate resolution or potential financial impact of these proceedings on our
financial condition or results of operations.

   We and our parent have been named as defendants in three lawsuits recently
filed in U.S. District Court for the Eastern District of Michigan. Northwest
Airlines is also named as a defendant in each action, while Delta Air Lines and
the Airlines Reporting Corporation are named as defendants in two of the cases.
The complaints are brought on behalf of a class of airline passengers who
originated or terminated their trips at the defendant carriers' respective
hubs. These passengers allege that they paid excessive fares due to the
respective airlines' enforcement of ticketing rules, which prohibit the use of
a connecting segment coupon, which is part of a through-fare ticket, where the
passenger does not fly or intend to fly the entire ticketed itinerary.
Plaintiffs allege monopolization and restraint of trade in violation of federal
antitrust laws. They seek recovery of unquantified treble-damages and an
injunction prohibiting future enforcement of the rules at issue. We believe the
claims against us are without merit and intend to pursue a vigorous defense.

   Commencing on May 24, 2000, we, along with several of our officers and
directors and, in all suits other than one, UAL Corporation, have been named as
defendants in eight, putative class actions filed in the Court of Chancery of
the State of Delaware in and for the New Castle County. The plaintiffs allege
that they have been and will be damaged by the agreement reached between our
parent, UAL Corporation, and Robert Johnson with respect to the acquisition by
an entity established by Mr. Johnson of certain assets located at Reagan
National Airport that are to be divested by us in connection with the
consummation of the merger. The plaintiffs allege, among other things, that the
individual defendants have breached their duty of loyalty and their fiduciary
duties in entering into the agreement with Mr. Johnson. Plaintiffs seek, among
other things, declaratory and injunctive relief, unspecified compensatory
damages and attorney's fees. We believe that these actions are without merit
and intend to conduct a vigorous defense.

   We were also named as a nominal defendant in a derivative action filed in
the Court of Chancery based upon the same allegations. The derivative plaintiff
brought causes of action for (i) breach of fiduciary duty; (ii) gross
mismanagement; and (iii) corporate waste of assets. The plaintiff in the
derivative action seeks, among other things, declaratory and equitable relief,
unspecified compensatory damages and attorney's fees. We believe these actions
are also without merit and intend to conduct a vigorous defense.

                                USE OF PROCEEDS


   All proceeds from the sale of the certificates will be deposited with the
depositary on behalf of the escrow agent for the benefit of the
certificateholders of the pass through trust. Upon the request of the pass
through trustee, the escrow agent will withdraw the deposits and deliver such
proceeds to the pass through trustee to purchase one or more secured promissory
notes.

   If an owner trustee issues the secured promissory notes, the owner trustee
will use the proceeds of the sale of the secured promissory notes to finance or
refinance a portion of the purchase price of an aircraft. Upon the purchase of
an aircraft by an owner trustee, the aircraft will be leased by the owner
trustee to us.

   If we issue secured promissory notes, we will use the proceeds from the sale
of the secured promissory notes to finance or refinance the purchase of
aircraft that we will own.

                        DESCRIPTION OF THE CERTIFICATES

   The following is a summary of the general terms and provisions of the
certificates. This description supplements and, to the extent it is
inconsistent with the description of the certificates in the prospectus,
replaces that description. The statements under this caption are summaries and
do not purport to be complete and are qualified in their entirety by reference
to all the provisions of the Basic Agreement, filed with the SEC as an exhibit
to the Form 8-K, filed with the SEC on September 7, 1999, and to the provisions
of the certificates, the pass through trust supplement, the Deposit Agreement,
the Escrow Agreement, the Liquidity Facility, the Policy, and the Intercreditor
Agreement, each of which we will file as an exhibit to an Annual Report on Form
10-K, a Quarterly Report on Form 10-Q, or a Current Report on Form 8-K with the
SEC.

   Except as otherwise indicated, the following summary relates to the pass
through trust and the certificates issued by the pass through trust. The
references to sections in parentheses in the following summary are to the
relevant sections of the Basic Agreement unless otherwise indicated.

General

   Each certificate will represent a fractional undivided interest in the US
Airways 2000-2G pass through trust, also referred to as the pass through trust.
The pass through trust will be formed pursuant to the Basic Agreement and a
separate trust supplement. We will refer to the supplement as a pass through
trust supplement and we will refer to the Basic Agreement as supplemented by
the pass through trust supplement collectively as the pass through trust
agreement. We will refer to the certificates issued by the pass through trust
either as the class G certificates or the certificates. State Street Bank and
Trust Company of Connecticut, National Association, will be the initial pass
through trustee of the pass through trust.

   The property of the pass through trust will consist of:

  .  Subject to the Intercreditor Agreement, secured promissory notes
     acquired under the Note Purchase Agreement and issued, at our election,
     either (a) on a nonrecourse basis by the Owner Trustees of separate
     owner trusts for a separate leveraged lease transaction for each leased
     aircraft to finance or refinance a portion of the purchase price of such
     leased aircraft by the Owner Trustee, in which case the applicable

     connection with each separate secured loan transaction for each owned
     aircraft to finance or refinance a portion of the purchase price of such
     owned aircraft by us.

  .  The rights of the pass through trust under the Escrow Agreement to
     request the Escrow Agent to withdraw from the Depositary funds
     sufficient to enable the pass through trust to purchase secured
     promissory notes on the financing date of each aircraft during the
     Delivery Period.

  .  The rights of the pass through trust under the Intercreditor Agreement
     (including all monies receivable in respect of such rights).

  .  Monies receivable under the Liquidity Facility.

  .  All monies receivable under the Policy.

  .  Funds from time to time deposited with the pass through trustee in
     accounts relating to the pass through trust.

   The certificates of the pass through trust will be issued in fully
registered form only and will be subject to the provisions described below
under "--Book-Entry; Delivery and Form." Certificates will be issued only in
minimum denominations of $1,000 or integral multiples of $1,000, except that
one certificate of the pass through trust may be issued in a different
denomination. (Section 3.01)

   The certificates will represent interests in the pass through trust, and all
payments and distributions on the certificates will be made only from the
property of the pass through trust. (Section 3.09) The certificates will not
represent an interest in or obligation of US Airways, the pass through trustee,
any of the Loan Trustees or Owner Trustees in their individual capacities, any
Owner Participant or any affiliate of any of them. Our parent, US Airways
Group, will not guarantee our obligations under the pass through trust
agreement or any other agreement described in this prospectus supplement.

   Under the Escrow Agreement, the holder of a certificate of the pass through
trust will also be the holder of an Escrow Receipt affixed to the certificate.
The holder of an Escrow Receipt will be entitled to certain rights with respect
to amounts held in certain accounts established under the Escrow Agreement.
Those accounts will be funded by payments made by the Depositary under the
Deposit Agreement.

   Any transfer of a certificate will have the effect of transferring the
corresponding rights with respect to such accounts. Escrow Receipts may not be
separately transferred by the holder of a certificate. Rights with respect to
the Deposits, payments and withdrawals to be made under the Deposit Agreement
and the Escrow Agreement, except for the right to request withdrawals for the
purchase of secured promissory notes, will not constitute property of the pass
through trust.

Payments and Distributions

   The following description of distributions on the certificates should be
read together with the description of the Intercreditor Agreement because the
Intercreditor Agreement may change the effect of the following provisions in a
default situation. See "Description of the Intercreditor Agreement--Priority of
Distributions." Each payment of interest on the Deposits with respect to the
pass through trust will be made by the Depositary to the Paying Agent and will
be distributed by the Paying Agent to the Receiptholders on the date receipt of
such payment is confirmed by the Paying Agent. Each payment of principal,
premium, if any, and interest on the secured promissory notes or payments on or
with respect to other trust property held in the pass through trust will be
distributed by the pass through trustee to certificateholders on the date
receipt of such payment is confirmed by the pass through trustee, except in the
case of certain types of Special Payments.

   The Deposits held with respect to the pass through trust and the secured
promissory notes held in the pass through trust, in the aggregate, will accrue
interest at the applicable annual rate for the certificates. Such interest will
be payable on February 5 and August 5 of each year, commencing on August 5,
2000 (or, in the case of secured promissory notes issued after such date,
commencing with the first such date to occur after initial issuance of such
secured promissory notes). The non-default interest rate applicable to the
certificates is referred to as the Stated Interest Rate. All such interest
payments will be distributed to certificateholders on

                                      S-39
<PAGE>

each such date until the final Distribution Date, subject to the Intercreditor
Agreement in the case of payments on the secured promissory notes. Interest is
calculated on the basis of a 360-day year consisting of twelve 30-day months.

   Payments of interest to the certificates will be supported by a Liquidity
Facility to be provided by the Liquidity Provider for the benefit of the
holders of the certificates in an aggregate amount sufficient to pay interest
on the certificates at the Stated Interest Rate on the next three successive
Regular Distribution Dates (without regard to any future payments of principal
on such certificates).

   The Liquidity Facility does not cover interest payable by the Depositary on
the Deposits. The Liquidity Facility will not provide for drawings thereunder
to pay for principal of or premium on the certificates or any interest on the
certificates in excess of the Stated Interest Rate or for more than three
seminannual installments of interest thereon. (Liquidity Facility, Section 2.2;
Intercreditor Agreement, Section 3.6)

   After use of any available funds under the Liquidity Facility or the Cash
Collateral Account, the payment of interest at the Stated Interest Rate will be
supported by the Policy provided by the Policy Provider. See "Description of
the Policy and the Policy Provider Agreement."

   Payments of principal of the secured promissory notes are scheduled to be
received by the pass through trustee on February 5 and August 5 in certain
years, depending upon the terms of the secured promissory notes held in the
pass through trust. The Final Maturity Date for the certificates is August 5,
2020.

   Payment of principal of the certificates on the Final Maturity Date, and in
certain limited circumstances, earlier payments of principal, will be supported
by the Policy. See "Description of the Policy and the Policy Provider
Agreement."

   The Paying Agent under the Escrow Agreement will distribute on each Regular
Distribution Date to the certificateholders all Scheduled Payments received in
respect of the related Deposits, the receipt of which is confirmed by the
Paying Agent on such Regular Distribution Date. The pass through trustee will
distribute, subject to the Intercreditor Agreement, on each Regular
Distribution Date to the certificateholders all Scheduled Payments received in
respect of secured promissory notes held on behalf of the pass through trust,
the receipt of which is confirmed by the pass through trustee on such Regular
Distribution Date. Each certificateholder will be entitled to receive its
proportionate share, based upon its fractional interest in the pass through
trust, of any distribution in respect of Scheduled Payments of interest on the
Deposits and, subject to the Intercreditor Agreement, of principal or interest
on secured promissory notes held by the Subordination Agent on behalf of the
pass through trust. Each such distribution of Scheduled Payments will be made
by the Paying Agent or pass through trustee to the certificateholders of record
on the record date applicable to such Scheduled Payment (generally 15 days
prior to each Regular Distribution Date) subject to certain exceptions.
(Sections 4.01 and 4.02; Escrow Agreement, Section 2.3) If a Scheduled Payment
is not received by the Paying Agent or pass through trustee on a Regular
Distribution Date but is received within five days after such Regular
Distribution Date, it will be distributed on the date received to such holders
of record. If it is received after such five-day period, it will be treated as
a Special Payment and distributed as described below.

   Any payment in respect of, or any proceeds of, any Trust Indenture Estate
under a Leased Aircraft Indenture, any secured promissory note or any
Collateral under an Owned Aircraft Indenture, other than a Scheduled Payment,
will be distributed on, in the case of an early redemption or a purchase of any
secured promissory note, the date of such early redemption or purchase (which
is a Business Day), and otherwise on the Business Day specified for
distribution of such Special Payment pursuant to a notice delivered by the pass
through trustee as soon as practicable after the pass through trustee has
received funds for such Special Payment. Any such distribution will be subject
to the Intercreditor Agreement.

   Any unused Deposits to be distributed after the Delivery Period Termination
Date or the occurrence of a Triggering Event, together with accrued and unpaid
interest on the Deposits, will be distributed on a date 15 days after the
Paying Agent has received notice of the event requiring such distribution (also
a Special

                                      S-40
<PAGE>

Distribution Date). However, if such date is within ten days before or after a
Regular Distribution Date, such Special Payment will be made on such Regular
Distribution Date. Payments made on or with respect to a Deposit are not
subject to the Intercreditor Agreement.

   The Paying Agent, in the case of the Deposits, and the pass through trustee,
in the case of trust property, will mail a notice to the certificateholders
stating the scheduled Special Distribution Date, the related record date, the
amount of the Special Payment and the reason for the Special Payment. In the
case of a redemption or purchase of the secured promissory notes or any
distribution of unused Deposits after the Delivery Period Termination Date or
the occurrence of a Triggering Event, such notice will be mailed not less than
15 days prior to the date such Special Payment is scheduled to be distributed,
and in the case of any other Special Payment, such notice will be mailed as
soon as practicable after the pass through trustee has confirmed that it has
received funds for such Special Payment. (Section 4.02(c); Trust Supplement,
Section 3.01; Escrow Agreement, Sections 2.3 and 2.6) Each distribution of a
Special Payment, other than a final distribution, on a Special Distribution
Date for the pass through trust will be made by the Paying Agent or the pass
through trustee, as applicable, to the certificateholders of record on the
record date applicable to such Special Payment. (Section 4.02(b); Escrow
Agreement, Section 2.3) See "--Indenture Defaults and Certain Rights upon an
Indenture Default" and "Description of the Secured Promissory Notes--
Redemption."

   If any distribution of proceeds from any "No Proceeds Drawing" or "Avoidance
Drawing" as described in "Description of the Policy and the Policy Provider
Agreement--The Policy" is made, the pass through trustee will mail a notice to
the certificateholders stating the scheduled Special Distribution Date, the
related record date, the amount of such distribution and the reason for such
distribution. The notice will be mailed not less than 20 days prior to the date
such proceeds are scheduled to be distributed. Each such distribution will be
made by the pass through trustee to the certificateholders of record on the
record date applicable to such distribution.

   The pass through trust agreement will require that the pass through trustee
establish and maintain a Certificate Account for the deposit of payments
representing Scheduled Payments received by the pass through trustee. Each pass
through trust agreement will require that the pass through trustee establish
and maintain a Special Payments Account for the deposit of payments
representing Special Payments received by the pass through trustee. A Special
Payments Account will be non-interest bearing except in certain circumstances
where the pass through trustee may invest amounts in such account in certain
permitted investments. The terms of the pass through trust agreement will
require the pass through trustee to deposit any Scheduled Payments relating to
the pass through trust received by it in the Certificate Account and to deposit
any Special Payments so received by it in the Special Payments Account.
(Section 4.01; Trust Supplement, Section 3.01) All amounts so deposited will be
distributed by the pass through trustee on a Regular Distribution Date or a
Special Distribution Date, as appropriate. (Section 4.02; Trust Supplement,
Section 3.01).

   The Escrow Agreement requires that the Paying Agent establish and maintain,
for the benefit of the Receiptholders, one or more Paying Agent Accounts, which
are to be non-interest bearing. The terms of the Escrow Agreement will require
the Paying Agent to deposit interest on Deposits and any unused Deposits
withdrawn by the Escrow Agent in the Paying Agent Account. All amounts so
deposited will be distributed by the Paying Agent on a Regular Distribution
Date or Special Distribution Date, as appropriate.

   The final distribution for the pass through trust will be made only upon
presentation and surrender of the certificates for such pass through trust at
the office or agency of the pass through trustee specified in the notice given
by the pass through trustee of such final distribution. The pass through
trustee will mail such notice of the final distribution to the
certificateholders, specifying the date set for such final distribution and the
amount of such distribution. (Trust Supplement, Section 7.01) See "--
Termination of the Pass Through Trust" below. Distributions in respect of
certificates issued in global form will be made as described in "--Book-Entry;
Delivery and Form" below.

   If any Distribution Date is on a day that is not a Business Day,
distributions scheduled to be made on such Regular Distribution Date or Special
Distribution Date will be made on the next succeeding Business Day with the
same force and effect as if made on such scheduled date and without additional
interest.

Pool Factors

   The following table sets forth the Assumed Amortization Schedule for the
secured promissory notes held in the pass through trust and resulting Pool
Factors. The actual aggregate principal amortization schedule applicable to the
pass through trust and the resulting Pool Factors may differ from those set
forth below, because the amortization schedule for the secured promissory notes
issued with respect to an aircraft may vary from such illustrative amortization
schedule so long as it complies with the Mandatory Economic Terms. The
scheduled distribution of principal payments for the pass through trust will be
affected if any secured promissory notes held in such pass through trust are
redeemed or purchased or if a default in payment on such secured promissory
notes has occurred. As a result, the aggregate principal amortization schedule
applicable to the pass through trust and the resulting Pool Factors may differ
from those set forth in the following table.

   The Pool Factor and Pool Balance of the pass through trust will be
recomputed if there has been delays in deliveries of Aircraft, an early
redemption, purchase, or default in the payment of principal or interest in
respect of one or more of the secured promissory notes held in the pass through
trust, as described in "--Indenture Defaults and Certain Rights Upon an
Indenture Default" and "Description of the Secured Promissory Notes--
Redemption," a special distribution attributable to unused Deposits after the
Delivery Period Termination Date or the occurrence of a Triggering Event or any
drawing under the Policy (other than in respect of interest on the certificates
(or on interest on the Deposits related to the Escrow Receipts attached to such
certificates) or any payments to the Liquidity Provider).

Reports to Certificateholders

   On each Distribution Date, the Paying Agent and pass through trustee will
include with each distribution by it of a Scheduled Payment or Special Payment
to certificateholders a statement setting forth the following information (per
$1,000 aggregate principal amount of certificate for such pass through trust,
except as to the amounts described in items (1) and (6) below):

     (1) The aggregate amount of funds distributed on such Distribution Date
  under the pass through trust agreement and under the Escrow Agreement,
  indicating the amount allocable to each source, including any portion which
  is paid by the Liquidity Provider and/or the Policy Provider.

     (2) The amount of such distribution under the pass through trust
  agreement allocable to principal and the amount allocable to premium, if
  any.

     (3) The amount of such distribution under the pass through trust
  agreement allocable to interest.

     (4) The amount of such distribution under the Escrow Agreement allocable
  to interest.

     (5) The amount of such distribution under the Escrow Agreement allocable
  to unused Deposits, if any.

     (6) The Pool Balance and the Pool Factor for the pass through trust.
  (Trust Supplement, Section 3.02(a))

   So long as the certificates are registered in the name of DTC, or its
nominee, on the record date prior to each Distribution Date, the pass through
trustee will request from DTC a securities position listing setting forth the
names of all DTC Participants reflected on DTC's books as holding interests in
the certificates on such record date. On each Distribution Date, the Paying
Agent and pass through trustee will mail to each such DTC Participant the
statement described above and will make available additional copies as
requested by such DTC Participant for forwarding to certificate owners. (Trust
Supplement, Section 3.02(a))

   In addition, after the end of each calendar year, the pass through trustee
and Paying Agent will furnish to each certificateholder at any time during the
preceding calendar year a report containing the sum of the amounts determined
pursuant to clauses (1), (2), (3), (4) and (5) above with respect to the pass
through trust for such calendar year or, in the event such person was a
certificateholder during only a portion of such calendar year, for the
applicable portion of such calendar year, and such other items as are readily
available to such pass through trustee and which a certificateholder reasonably
requests as necessary for the purpose of such certificateholder's preparation
of its U.S. federal income tax returns. (Trust Supplement, Section 3.02(b))
Such report and such other items will be prepared on the basis of information
supplied to the pass through trustee by the DTC Participants and will be
delivered by the pass through trustee to such DTC Participants to be available
for forwarding by such DTC Participants to certificate owners in the manner
described above. (Trust Supplement, Section 3.02(b)) At such time, if any, as
the certificates are issued in the form of definitive certificates, the Paying
Agent and pass through trustee will prepare and deliver the information
described above to each certificateholder of record as the name and period of
ownership of such certificateholder appears on the records of the registrar of
the certificates.

Indenture Defaults and Certain Rights upon an Indenture Default

   An event of default under a Leased Aircraft Indenture will include an event
of default under the related lease. We will refer to an event of default under
a lease as a Lease Event of Default. See "Description of the Secured Promissory
Notes--Indenture Defaults, Notice and Waiver." If series C secured promissory
notes are issued in addition to series G secured promissory notes under any
Indenture and such series C secured promissory notes are purchased by a class C
pass through trust, then a continuing Indenture Default under such Indenture
may affect the secured promissory notes held by each such pass through trust.
There are no cross-default provisions in the Indentures or in the leases. This
means that events resulting in an Indenture Default under any particular
Indenture may or may not result in an Indenture Default under any other
Indenture, and a Lease Event of Default under any particular lease may or may
not constitute a Lease Event of Default under any other lease. If an Indenture
Default occurs in fewer than all of the Indentures, notwithstanding the
treatment of secured promissory notes issued under any Indenture under which an
Indenture Default has occurred, payments of principal and interest on all of
the secured promissory notes will continue to be distributed to the holders of
the certificates as originally scheduled, subject to the Intercreditor
Agreement. See "Description of the Intercreditor Agreement--Priority of
Distributions."

   Under a Leased Aircraft Indenture, the applicable Owner Trustee and Owner
Participant will have the right under certain circumstances to cure Indenture
Defaults that result from the occurrence of a Lease Event of Default under the
related lease. If the Owner Trustee or the Owner Participant exercises any such
cure right, the Indenture Default will be deemed to have been cured.

   If class C certificates are issued and the same institution acts as pass
through trustee of multiple pass through trusts, in the absence of instructions
from the certificateholders of any such pass through trust, such pass through
trustee could be faced with a potential conflict of interest upon an Indenture
Default. In such event, the pass through trustee will resign as pass through
trustee of one or all such pass through trusts, and a successor trustee will be
appointed in accordance with the terms of the applicable pass through trust
agreement. State Street Bank and Trust Company of Connecticut, National
Association, will be the initial pass through trustee under the class G pass
through trust.

   After the occurrence and during the continuation of an Indenture Default,
the Controlling Party will direct the Loan Trustee under such Indenture in the
exercise of remedies under such Indenture and may accelerate and sell all (but
not less than all) of the secured promissory notes issued under such Indenture
to any person, subject to certain limitations. See "Description of the
Intercreditor Agreement--Intercreditor Rights--Sale of Secured Promissory Notes
or Aircraft." The proceeds of such sale will be distributed pursuant to the
provisions of the Intercreditor Agreement. Any such proceeds so distributed to
the pass through trustee upon any such sale will be deposited in the applicable
Special Payments Account and will be distributed to the certificateholders on a
Special Distribution Date. (Sections 4.01 and 4.02)

   The market for secured promissory notes at the time of the existence of an
Indenture Default may be very limited and there can be no assurance as to the
price at which they can be sold. If any such secured promissory notes are sold
for less than their outstanding principal amount, certificateholders may
receive a smaller amount of principal distributions than anticipated and will
not have any claim for the shortfall against US Airways, the Liquidity
Provider, any Owner Trustee, any Owner Participant or the pass through trustee.

   Any Special Payment made to the pass through trustee by the Subordination
Agent following an Indenture Default will be deposited in the Special Payments
Account and will be distributed to the certificateholders on a Special
Distribution Date. (Sections 4.01 and 4.02; Trust Supplement, Section 3.01) In
addition, if, following an Indenture Default under any Leased Aircraft
Indenture, the applicable Owner Participant or Owner Trustee exercises its
option to redeem or purchase the outstanding secured promissory notes issued
under such Leased Aircraft Indenture, the price paid by such Owner Participant
or Owner Trustee for the secured promissory notes issued under such Leased
Aircraft Indenture and distributed to the pass through trust by the
Subordination

                                      S-44
<PAGE>

Agent will be deposited in the Special Payments Account and will be distributed
to the certificateholders on a Special Distribution Date. (Sections 4.01 and
4.02)

   Any funds representing payments received with respect to any defaulted
secured promissory notes, or the proceeds from the sale of any secured
promissory notes, held by the pass through trustee in the Special Payments
Account will, to the extent practicable, be invested and reinvested by the pass
through trustee in Permitted Investments at our direction pending the
distribution of such funds on a Special Distribution Date. (Section 4.04)

   Each pass through trust agreement will provide that the pass through trustee
will, within 90 days after the occurrence of any default known to the pass
through trustee, give to the certificateholders notice, transmitted by mail, of
such uncured or unwaived default with respect to the pass through trust known
to it. However, except in the case of default in a payment of principal,
premium, if any, or interest on any of the secured promissory notes, the pass
through trustee will be protected in withholding such notice if it in good
faith determines that the withholding of such notice is in the interests of
such certificateholders. The term "default" as used in this paragraph only with
respect to the pass through trust means the occurrence of an Indenture Default
under any Indenture pursuant to which secured promissory notes held by the pass
through trust were issued, as described above, except that in determining
whether any such Indenture Default has occurred, any grace period or notice in
connection with such Indenture Default will be disregarded. (Section 7.02)

   The pass through trust agreement will contain a provision entitling the pass
through trustee, subject to the duty of the pass through trustee during a
default to act with the required standard of care, to be offered reasonable
security or indemnity by the holders of the certificates before proceeding to
exercise any right or power under such pass through trust agreement at the
request of such certificateholders. (Section 7.03(e))

   Subject to certain qualifications set forth in the pass through trust
agreement and to the Intercreditor Agreement, the certificateholders holding
certificates evidencing fractional undivided interests aggregating not less
than a majority in interest in the pass through trust will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the pass through trustee with respect to the pass through trust or
pursuant to the terms of the Intercreditor Agreement, or exercising any trust
or power conferred on the pass through trustee under the pass through trust
agreement or the Intercreditor Agreement, including any right of the pass
through trustee as Controlling Party under the Intercreditor Agreement or as
holder of the secured promissory notes. (Section 6.04)

   In certain cases, but subject to the qualifications noted above, the
certificateholders evidencing fractional undivided interests aggregating not
less than a majority in interest of the pass through trust may on behalf of the
holders of all the certificates of such pass through trust waive any past
"event of default" under the pass through trust (i.e., any Indenture Default
under any Indenture pursuant to which secured promissory notes held by the pass
through trust were issued) and its consequences or, if the pass through trustee
is the Controlling Party, may direct the pass through trustee to instruct the
applicable Loan Trustee to waive any past Indenture Default and its
consequences, except (a) a default in the deposit of any Scheduled Payment or
Special Payment or in the distribution of any Scheduled Payment or Special
Payment, (b) a default in payment of the principal, premium, if any, or
interest with respect to any of the secured promissory notes and (c) a default
in respect of any covenant or provision of the pass through trust agreement
that cannot be modified or amended without the consent of each
certificateholder affected by such default. (Section 6.05) Each Indenture will
provide that, with certain exceptions, the holders of the majority in aggregate
unpaid principal amount of the secured promissory notes issued under such
Indenture may on behalf of all such holders waive any past default or Indenture
Default under such Indenture. Notwithstanding such provisions of the
Indentures, under the Intercreditor Agreement only the Controlling Party will
be entitled to waive any such past default or Indenture Default.

PTC Event of Default

   A PTC Event of Default under the pass through trust agreement means the
failure to pay:

  .  The outstanding Pool Balance of the certificates within ten Business
     Days of the Final Maturity Date (unless the Subordination Agent has made
     a drawing under the Policy in an aggregate amount sufficient to pay the
     outstanding Pool Balance and has distributed such amount to the pass
     through trustee).

  .  Interest due on the certificates within ten Business Days of any
     Distribution Date (unless the Subordination Agent has made Interest
     Drawings, or withdrawals from the Cash Collateral Account for the
     certificates, or a drawing under the Policy, in an aggregate amount
     sufficient to pay such interest and has distributed such amount to the
     pass through trustee). (Section 1.01)
   Any failure to make expected principal distributions for the certificates on
any Regular Distribution Date (other than the Final Maturity Date) will not
constitute a PTC Event of Default for such certificates. A PTC Event of Default
for the most senior outstanding class of certificates resulting from an
Indenture Default under all Indentures will constitute a "Triggering Event."
See "Description of the Intercreditor Agreement--Priority of Distributions--
After a Triggering Event" for a discussion of the consequences of a Triggering
Event.

Merger, Consolidation and Transfer of Assets

   We will be prohibited from consolidating with or merging into any other
corporation or transferring substantially all of our assets as an entirety to
any other entity unless:

  .  The surviving successor corporation or transferee is validly existing
     under the laws of the United States or any state of the United States or
     the District of Columbia.

  .  The surviving successor corporation or transferee is a "citizen of the
     United States" (as defined in the Transportation Code) holding an air
     carrier operating certificate issued by the Secretary of Transportation
     (or issued by the administrator of the FAA acting under the authority of
     the Secretary of Transportation) pursuant to Chapter 447 of Title 49,
     United States Code, if, and so long as, such status is a condition of
     entitlement to the benefits of Section 1110 of the U.S. Bankruptcy Code.

  .  The surviving successor corporation or transferee expressly assumes all
     of our obligations contained in the Basic Agreement and the pass through
     trust supplement, the Note Purchase Agreement, the Indentures, the
     Participation Agreements, the leases and any other operative documents.

  .  We deliver a certificate and an opinion or opinions of counsel
     indicating that such transaction, in effect, complies with such
     conditions.

   In addition, after giving effect to such transaction, no Lease Event of
Default, in the case of a leased aircraft, or Indenture Default, in the case of
an owned aircraft, will have occurred and be continuing. (Section 5.02; Trust
Supplement, Section 8.01; Special Leased Aircraft Participation Agreement,
Section 7(s); Basic Leased Aircraft Participation Agreement, Section 7(v);
Owned Aircraft Participation Agreement, Section 7(e))

   The Basic Agreement, the pass through trust supplement, the Note Purchase
Agreement, the Indentures, the Participation Agreements and the leases will not
contain any covenants or provisions that would give the pass through trustee or
certificateholders protection in the event of a highly leveraged transaction,
including transactions effected by management or affiliates, which may or may
not result in a change in control of US Airways.

Modifications of the Pass Through Trust Agreements and Certain Other Agreements

   The pass through trust agreement will contain provisions permitting, at our
request, the execution of amendments or supplements to such pass through trust
agreement or, if applicable, to the Deposit Agreement,

     defective or inconsistent with any other provision in the pass through
     trust agreement, the Deposit Agreement, the Escrow Agreement, the
     Intercreditor Agreement, the Note Purchase Agreement, the Liquidity
     Facility, the Policy or the Policy Provider Agreement, as applicable, or

     matters or questions arising under the pass through trust agreement, the
     Deposit Agreement, the Escrow Agreement, the Intercreditor Agreement,
     the Note Purchase Agreement, the Liquidity Facility, the Policy or the
     Policy Provider Agreement, provided that such action will not materially
     adversely affect the interests of the holders of the certificates.

     Intercreditor Agreement, the Note Purchase Agreement, the Liquidity
     Facility, the Policy or the Policy Provider Agreement.

     agreement, the Deposit Agreement, the Escrow Agreement, the
     Intercreditor Agreement, the Note Purchase Agreement, the Liquidity
     Facility, the Policy or the Policy Provider Agreement to such extent as
     is necessary to continue the qualification of the pass through trust
     agreement (including any supplemental agreement) under the Trust
     Indenture Act of 1939, or any similar federal statute enacted after the
     execution of the pass through trust agreement, and to add to the pass
     through trust agreement, the Deposit Agreement, the Escrow Agreement,
     the Intercreditor Agreement, the Note Purchase Agreement, the Liquidity
     Facility, the Policy or the Policy Provider Agreement such other
     provisions as may be expressly permitted by the Trust Indenture Act.

  .  To evidence and provide for the acceptance of appointment under the pass
     through trust agreement, the Deposit Agreement, the Escrow Agreement,

     the pass through trust agreement, the Deposit Agreement, the Escrow
     Agreement, the Intercreditor Agreement, the Note Purchase Agreement, the
     Liquidity Facility, the Policy or the Policy Provider Agreement as is
     necessary to provide for or facilitate the administration of the pass
     through trust under the Basic Agreement by more than one pass through
     trustee.

   In each case, such modification or supplement may not adversely affect the
status of the pass through trust as a grantor trust under Subpart E, Part I of
Subchapter J of Chapter 1 of Subtitle A of the Code for U.S. federal income tax
purposes. (Section 9.01; Trust Supplement, Section 6.01)

                                      S-47
<PAGE>

   A majority of the certificateholders of the pass through trust may amend or
supplement the provisions of the pass through trust agreement, the Deposit
Agreement, the Escrow Agreement, the Intercreditor Agreement, the Note Purchase
Agreement, the Policy or the Liquidity Facility to the extent applicable to
such certificateholders or may modify the rights and obligations of such
certificateholders under the pass through trust agreement, the Deposit
Agreement, the Escrow Agreement, the Intercreditor Agreement, the Note Purchase
Agreement, the Liquidity Facility or the Policy. No such amendment or
supplement may, without the consent of the holder of each certificate so
affected by such amendment or supplement:

  .  Reduce in any manner the amount of, or delay the timing of, any receipt
     by the pass through trustee (or, with respect to the Deposits, the
     Receiptholders) of payments with respect to the secured promissory notes
     held in the pass through trust or distributions in respect of any
     certificate (or, with respect to the Deposits, payments to be made to
     Receiptholders), or change the date or place of any payment in respect
     of any certificate, or make distributions payable in coin or currency
     other than that provided for in such certificates, or impair the right
     of any certificateholder to institute suit for the enforcement of any
     such payment when due.

  .  Permit the disposition of any secured promissory note held in the pass
     through trust, except as provided in the pass through trust agreement,
     or otherwise deprive such certificateholder of the benefit of the
     ownership of the applicable secured promissory notes.

  .  Alter the priority of distributions specified in the Intercreditor
     Agreement in a manner materially adverse to the certificateholders.

  .  Reduce the percentage of the aggregate fractional undivided interests of
     the pass through trust provided for in the pass through trust agreement,
     the consent of the holders of which is required for any supplemental
     trust agreement or for any waiver provided for in the pass through trust
     agreement.

  .  Modify any of the provisions relating to the rights of the
     certificateholders in respect of the waiver of events of default or
     receipt of payment except to increase any percentage of
     certificateholders required to effect a waiver or to add to the list of
     provisions that may not be altered without the consent of each
     certificateholder affected thereby. (Section 9.02; Trust Supplement,
     Section 6.02)

  .  Terminate or modify the Policy, other than endorsements already
     contemplated or required by Section 2.6(c) or 3.7(c) of the
     Intercreditor Agreement.

   In the event that the pass through trustee, as holder (or beneficial owner
through the Subordination Agent) of any secured promissory note in trust for
the benefit of the certificateholders or as Controlling Party under the
Intercreditor Agreement, receives (directly or indirectly through the
Subordination Agent) a request for a consent to any amendment, modification,
waiver or supplement under any Indenture, any Participation Agreement, any
lease, any secured promissory note or any other related document, the pass
through trustee will promptly send a notice of such proposed amendment,
modification, waiver or supplement to each certificateholder registered on the
register of the pass through trust as of the date of such notice and the Policy
Provider. See "Description of the Intercreditor Agreement--Intercreditor
Rights--Controlling Party." The pass through trustee will request from the
certificateholders a direction as to:

  .  Whether or not to take or refrain from taking (or direct the
     Subordination Agent to take or refrain from taking) any action which a
     holder of such secured promissory note or the Controlling Party has the
     option to direct.

  .  Whether or not to give or execute (or direct the Subordination Agent to
     give or execute) any waivers, consents, amendments, modifications or
     supplements as a holder of such secured promissory note or as
     Controlling Party.

  .  How to vote (or direct the Subordination Agent to vote) any secured
     promissory note if a vote has been called for with respect to such
     amendment, modification, waiver or supplement.

                                      S-48
<PAGE>

   Provided such a request for certificateholder direction has been made, in
directing any action or casting any vote or giving any consent as the holder of
any secured promissory note (or in directing the Subordination Agent in any of
the foregoing) the pass through trustee will:

  .  Other than as Controlling Party, vote for or give consent to any such
     action with respect to such secured promissory note in the same
     proportion as that of (x) the aggregate face amount of all certificates
     actually voted in favor of or for giving consent to such action by such
     direction of certificateholders to (y) the aggregate face amount of all
     outstanding certificates.

  .  As the Controlling Party, vote as directed in such certificateholder
     direction by the certificateholders evidencing fractional undivided
     interests aggregating not less than a majority in interest in the pass
     through trust.

   For purposes of the certificateholder directions described above, a
certificate is deemed "actually voted" if the certificateholder has delivered
to the pass through trustee an instrument evidencing such certificateholder's
consent to such direction prior to one Business Day before the pass through
trustee directs such action or casts such vote or gives such consent.
Notwithstanding the foregoing, but subject to certain rights of the
certificateholders under the pass through trust agreement and subject to the
Intercreditor Agreement, the pass through trustee may, in its own discretion
and at its own direction, consent and notify the relevant Loan Trustee of such
consent (or direct the Subordination Agent to consent and notify the relevant
Loan Trustee of such consent) to any amendment, modification, waiver or
supplement under the relevant Indenture, Participation Agreement or lease, any
relevant secured promissory note or any other related document, if an Indenture
Default under any Indenture has occurred and is continuing, or if such
amendment, modification, waiver or supplement does not materially adversely
affect the interests of the certificateholders. (Section 10.01)

Obligation to Purchase Secured Promissory Notes

   The pass through trustee will be obligated to purchase the secured
promissory notes issued with respect to the aircraft during the Delivery
Period, subject to the terms and conditions of the Note Purchase Agreement and
the applicable Participation Agreement. Under the Note Purchase Agreement, we
agree to finance each aircraft in the manner provided in the Note Purchase
Agreement. We will have the option of entering into a leveraged lease financing
or a secured debt financing with respect to each aircraft.

  .  If we choose to enter into a leveraged lease financing with respect to
     an aircraft, the Note Purchase Agreement provides for the relevant
     parties to enter into a Participation Agreement, a lease and a Leased
     Aircraft Indenture relating to the financing of such leased aircraft.

  .  If we choose to enter into a secured debt financing with respect to an
     aircraft that we own, the Note Purchase Agreement provides for the
     relevant parties to enter into a Participation Agreement and an Owned
     Aircraft Indenture relating to the financing of such owned aircraft.

   We currently expect to enter into a separate leveraged lease financing for
all 20 aircraft described in this prospectus supplement. We have entered into a
commitment letter, subject to certain terms and conditions, pursuant to which a
single owner participant has agreed to provide the equity portion of each
leveraged lease financing. For such owner participant, the leveraged lease
documents will be substantially in the forms attached to the Note Purchase
Agreement designated as the "Form of Special Leased Aircraft Participation
Agreement," "Form of Special Lease," "Form of Special Leased Aircraft
Indenture" and "Form of Special Trust Agreement". If another owner participant
enters into a leveraged lease financing of an Aircraft, the leveraged lease
documents will be substantially in the forms attached to the Note Purchase
Agreement designated as the "Form of Basic Leased Aircraft Participation
Agreement," "Form of Basic Lease," "Form of Basic Leased Aircraft Indenture"
and "Form of Basic Trust Agreement".

 Transaction Structure for Leased Aircraft

   The following diagram illustrates transactions in connection with the
purchase of secured promissory notes by the pass through trustee to finance
leased aircraft. We anticipate that separate transactions similar to the
transactions illustrated in the diagram will occur for each U.S. leveraged
lease transaction financed with the proceeds of the offering of the
certificates. At our request or at the request of an Owner Participant, the
structure illustrated below may change so that the actual cash flows on the
closing of any lease financing may vary.



[Diagram omitted, which shows leased aircraft notes will be issued by an owner
trustee in a leveraged lease transaction.  The diagram shows that we will sell
the leased aircraft to an owner trust that will, in turn, lease the aircraft
back to us.  The owner participant is the beneficial owner of the owner trust
and contributes a portion of the purchase price of the aircraft.  The owner
trust will enter into an indenture with the loan trustee providing for a
security interest in the leased aircraft, the assignment of the lease and the
issuance of secured promissory notes to finance the remaining portion of the
purchase price of the aircraft.  The owner trustee will sell the service G
secured promissory notes to the class G pass through trust. The class G pass
through trust will sell certificates to class G certificateholders for cash.
The proceeds from the sale of the certificates initially will be held in
escrow and deposited with the depositary.  As each aircraft is financed, the
class G pass through trust will withdraw amounts from the depositary necessary
to purchase the applicable secured promissory notes and pass such amounts
through to the loan trustee who in turn will forward the proceeds to the owner
trust as payment for the secured promissory notes.]

--------
(1) We may sell aircraft we own to the owner trust in a leveraged lease
    transaction. In some instances, the owner trust may purchase aircraft
    directly from the manufacturer or from other persons.
(2) Each leased aircraft will be subject to a separate lease.
(3) Because the owner trustee assigns these payments to the loan trustee, we
    will make these payments directly to the loan trustee.
(4) Because the sale of the certificates occurs prior to the closing of each
    leveraged lease transaction, the proceeds from the sale of the certificates
    will initially be held in escrow by the escrow agent and deposited with the
    depositary. The depositary will hold such funds as interest-bearing
    deposits. In connection with each leveraged lease transaction, amounts are
    withdrawn from the deposit for the pass through trust and used to acquire
    secured promissory notes.

 Transaction Structure for Owned Aircraft

   The following diagram illustrates transactions in connection with the
purchase of secured promissory notes by the pass through trustees to finance
owned aircraft. We anticipate that separate transactions similar to the
transactions illustrated in the diagram will occur for each owned aircraft
financed with the proceeds of the offering of the certificates.

[Diagram omitted, which shows that we may finance or refinance aircraft that we
own through the issuance of owned aircraft notes.  The diagram also shows that
we will enter into an indenture with the loan trustee providing for a security
interest in the owned aircraft and the issuance of secured promissory notes.
We will sell the class G secured promissory notes to the class G pass through
trust.  The class G pass through trust will sell certificates to class G
certificateholders, for cash.  The proceeds from the sale of the certificates
initially will be held in escrow and deposited with the depositary. As each
aircraft is financed, the class G pass through trust will withdraw amounts
from the depositary necessary to purchase the applicable secured promissory
notes and pass such amounts through to the loan trustee who will in turn
forward the proceeds to us as payment for the secured promissory notes.  We
will then purchase owned aircraft from those proceeds.]
--------
(1) Because the sale of the certificates may occur prior to the financing of an
    owned aircraft, the proceeds from the sale of certificates, in that
    circumstance, will initially be held in escrow by the escrow agent and
    deposited with the depositary. The depositary will hold such funds as
    interest-bearing deposits. In connection with the closing of each owned
    aircraft financing, amounts are withdrawn from the deposit for the pass
    through trust and used to acquire secured promissory notes.

 Mandatory Terms

   The description of the Participation Agreements, the leases, the Leased
Aircraft Indentures and the Owned Aircraft Indentures in this prospectus
supplement is based on the forms of such agreements to be utilized pursuant to
the Note Purchase Agreement. The terms of the agreements actually entered into
may differ from the forms of such agreements and, as a result, may differ from
the description of such agreements contained in this prospectus supplement.
However, under the Note Purchase Agreement, the terms of such agreements are
required to (a) contain the Mandatory Document Terms (as such Mandatory
Document Terms are permitted to vary in accordance with the terms of the Note
Purchase Agreement) and (b) not vary the Mandatory Economic Terms. In addition,
we must (1) certify to the pass through trustee and the Policy Provider that
any permitted modifications do not materially and adversely affect the
certificateholders or the Policy Provider, and (2) if such agreements are
modified in any material respect, we must obtain the written consent of the
Policy Provider and written confirmation from each Rating Agency that the use
of versions of such agreements modified in any material respect will not result
in a withdrawal, suspension or downgrading of the rating of the certificates.
If Policy Provider consent and Rating Agency Confirmation has been received
with respect to any financing agreements and such financing agreements are used
without material modification, no additional Policy Provider consent or Rating
Agency Confirmation shall be required.

   Under the Note Purchase Agreement, it is a condition precedent to the
obligation of the pass through trustee to purchase the secured promissory notes
related to the financing of an aircraft that no Triggering Event has occurred.
The pass through trustee has no right or obligation to purchase secured
promissory notes after the Delivery Period Termination Date.

   The "Mandatory Economic Terms," as defined in the Note Purchase Agreement,
will require, among other things, that:

  .  The maximum principal amount of the secured promissory notes issued with
     respect to an aircraft must not exceed the principal amount of secured
     promissory notes indicated for each such aircraft as set forth in
     "Prospectus Supplement Summary--Secured Promissory Notes and the
     Aircraft" under the column "Maximum Principal Amount of Series G Secured
     Promissory Notes."

  .  The loan to aircraft value ratio for the secured promissory notes for
     each aircraft (computed as of the respective dates below on the basis of
     the Assumed Appraised Value of such aircraft and the Depreciation
     Assumption) must not exceed, as of the issuance date of such secured
     promissory notes and any Regular Distribution Date after secured
     promissory notes are issued for that aircraft (assuming no default in
     the payment of the secured promissory notes), the percentages set forth
     in the following table:

  .  The initial average life of the secured promissory notes on any aircraft
     must not be less than 11 years and not extend beyond 13 years from the
     Issuance Date.

  .  The interest rate applicable to the secured promissory notes must equal
     the rate applicable to the certificates issued by the pass through
     trust.

  .  The past due rate applicable to the secured promissory notes must not be
     less than the interest rate applicable to such series of secured
     promissory notes plus 1% per annum.

  .  At the Delivery Period Termination Date, the aggregate principal amount
     of the secured promissory notes will equal the original aggregate face
     amount of the certificates, without giving effect to any scheduled
     principal payments on such secured promissory notes but after giving
     effect to any reductions to the Pool Balance for the certificates from
     deposits not used to purchase secured promissory notes on or before such
     date.

  .  The payment dates for the secured promissory notes and basic rent under
     the leases must be February 5 and August 5.

  .  The basic lease term for each lease must expire by its terms on or after
     the latest maturity date of the secured promissory notes.

  .  As of the Delivery Period Termination Date, the average life of the
     certificates must not be more than 12.1 years from the Issuance Date
     (computed without regard to the acceleration of any secured promissory
     notes and after giving effect to any special distribution on the
     certificates after the Issuance Date required in respect of unused
     Deposits).

  .  As of the Delivery Period Termination Date and each Regular Distribution
     Date after the Delivery Period Termination Date, the loan to aircraft
     value ratio for the certificates (computed as of any such date on the
     basis of the Assumed Appraised Value of all aircraft that have been
     delivered and the Depreciation Assumption), must not exceed (assuming no
     default in the payment of the secured promissory notes and after giving
     effect to Scheduled Payments) 50.5%.

  .  The final expected distribution date of the certificates is as set forth
     in the "Prospectus Supplement Summary--Summary of Terms of
     Certificates."

  .  Each installment of basic rent, together with any advances or payments
     by us and any payment of deferred equity amounts by an Owner Participant
     under the leases and related agreements must be sufficient for the Owner
     Trustee to pay in full, on the date on which each installment of basic
     rent, advance, other payment or deferred equity is due, any payments
     scheduled to be made on account of principal of, and interest on, the
     related secured promissory notes. If an Owner Participant is required to
     make a deferred equity payment to be used by an Owner Trustee to pay
     principal of, and interest on, the secured promissory notes and the
     Owner Participant fails to make the payment, we will be required to
     provide the Owner Trustee with funds sufficient to make the payment.
     Termination values (or other comparable termination amounts), together
     with all other amounts payable by us upon termination of any lease, and
     the amount of premium, if any payable by the Owner Trustee, must be
     sufficient to pay amounts due with respect to the related secured
     promissory notes.

  .  The amounts payable under the all-risk aircraft hull insurance
     maintained with respect to each aircraft must be sufficient to pay the
     applicable termination value (or other comparable termination amount),
     subject to certain rights of self-insurance.

  .  The (a) past due rate in the Indentures and the leases, (b) Make-Whole
     Premium payable under the Indentures, (c) provisions relating to the
     redemption and purchase of secured promissory notes in the Indentures
     and (d) minimum liability insurance amount on aircraft in the leases, in
     each case must be no less favorable to the Loan Trustees, Subordination
     Agent, Liquidity Provider, Policy Provider, pass through trustee and
     Note Holders than as set forth in the Aircraft Operative Agreements
     designated as the "Form of Basic Leased Aircraft Participation
     Agreement," "Form of Basic Lease" and "Form of Basic Leased Aircraft
     Indenture" annexed to the Note Purchase Agreement.

  .  The indemnification of the Loan Trustees, Subordination Agent, Liquidity
     Provider, Policy Provider, pass through trustee and Note Holders with
     respect to certain taxes and expenses, in each case must not be
     materially less favorable to the Loan Trustees, Subordination Agent,
     Liquidity Provider, Policy Provider, pass through trustee and Note
     Holders than as set forth in the Aircraft Operative Agreements
     designated as the "Form of Basic Leased Aircraft Participation
     Agreement," "Form of Basic Lease" and "Form of Basic Leased Aircraft
     Indenture" annexed to the Note Purchase Agreement.

   The "Mandatory Document Terms" prohibit modifications in any material
adverse respect as regards the interests of the Loan Trustees, Subordination

Agreement, as follows:

  .  In the case of the Indentures, the following modifications are

        aircraft purchase agreement with an affiliate of the aircraft
        manufacturer and, (c) in the case of a leased aircraft, the lease
        or (B) to eliminate the obligations intended to be secured by the
        Indenture;

    (2) modifications to certain provisions relating to the issuance,
        redemption, purchase, payments, and ranking of the secured
        promissory notes (including the obligation to pay the Make-Whole
        Premium in certain circumstances);

    (3) modifications to certain provisions regarding Indenture Defaults,
        remedies relating to Indenture Defaults and rights of the Owner
        Trustee and Owner Participant in such circumstances;

    (4) modifications to certain provisions requiring the Loan Trustee to
        act upon instructions of the Note Holders and regarding the rights
        of the Owner Trustee and the Owner Participant to take actions
        under the lease;

    (5) modifications to certain provisions relating to any replaced
        airframe or engines with respect to an aircraft;

        the Indenture except for the Loan Trustee, the Note Holders and
        certain other parties specified in the Indenture;

    (8) modifications to the provision that New York law will govern the
        Indentures; and

    (9) modifications to the provision stating that all votes of the Note
        Holders will be governed by the vote of a majority in interest of
        the Note Holders, except as otherwise expressly provided in the
        Indenture.

  .  In the case of the leases, the following modifications are prohibited:

    (1) modifications to certain provisions regarding our unconditional
        obligation to pay, prepay or advance basic rent, termination value
        and certain other amounts to the Owner Trustee in an aggregate
        amount at least equal to scheduled interest and principal;

    (2) modification of our obligations to record the Leased Aircraft
        Indenture with the FAA and to maintain such Indenture as a first-
        priority perfected mortgage on the related aircraft;

        respect to a replacement airframe; and

                                      S-54
<PAGE>

    (4) modification of our obligations to consent to the assignment of the
        lease by the Owner Trustee as collateral under the Leased Aircraft
        Indenture, as well as modifications which would either alter the

        leases.

  .  In the case of the Participation Agreements, the following modifications
     are prohibited:

    (1) modifications to certain conditions to the obligations of the pass

        to such aircraft, (c) delivery of an opinion of outside counsel
        with respect to the entitlement to the benefits of Section 1110
        with respect to such aircraft and the delivery of certain other

        Participation Agreement; and

    (5) modification to the provision stating that it is the intent of the
        parties that the Loan Trustee be entitled to the benefits of
        Section 1110 of the U.S. Bankruptcy Code with respect to
        repossession of the applicable aircraft if we are a debtor in a
        case under Chapter 11 of the U.S. Bankruptcy Code.

  .  In the case of all of the Aircraft Operative Agreements, modifications
     are prohibited that materially and adversely affect the interests of the
     Note Holders, Subordination Agent, Liquidity Provider, Policy Provider
     or Loan Trustee in the definition of "Make-Whole Premium."

   Notwithstanding the foregoing, any such Mandatory Document Term may be
modified to correct or supplement any such provision which may be defective or
to cure any ambiguity or correct any mistake, provided that any such action
does not materially and adversely affect the interests of the Note Holders,
Subordination Agent, Liquidity Provider, Policy Provider, Loan Trustees or
certificateholders.

Possible Issuance of Class C Certificates

   We may elect to issue class C certificates. The Note Purchase Agreement
provides that we may not issue class C certificates unless we obtain written
confirmation from each Rating Agency that the issuance of such class C
certificates will not result in a withdrawal or downgrading of the rating of
the class G certificates (without regard to the Policy). If class C
certificates are issued, the pass through trustee with respect to such class C
certificates will become a party to the Intercreditor Agreement and any
purchaser of the class C certificates will be subject to the subordination
provisions in that agreement, including the provisions of the Intercreditor
Agreement that allow the Controlling Party, during the continuance of an
Indenture Default, to direct the Loan Trustee in taking action under the
applicable Indenture. We will not issue any class C certificates at any time
prior to the consummation of this offering.

   Series C secured promissory notes may be issued with respect to an aircraft.
The series C secured promissory notes, if any are issued, will be subordinated
to the series G secured promissory notes. The purchaser of the series C secured
promissory notes may be a pass through trust or another person or entity. In
any event, the series C secured promissory notes purchased by any pass through
trust or other person or entity will be subject to the provisions of the
Intercreditor Agreement that allow the Controlling Party, during the
continuance of an Indenture Default, to direct the Loan Trustee in taking
action under the applicable Indenture.

Purchase Rights of Potential Class C Certificateholders and the Policy Provider

   Upon the occurrence and during the continuation of a Triggering Event, with
ten days' written notice to the class C pass through trustee and to each
certificateholder:

  .  if class C pass through trust certificates have been issued, the class C
     certificateholders will have the right to purchase all, but not less
     than all of the class G certificates; and

  .  whether or not any class C certificates are issued or any such purchase
     right is exercised by the class C certificateholders, if such class C
     certificates are issued, the Policy Provider, if it is the Controlling
     Party and 180 days have elapsed since the occurrence of a Triggering
     Event that is continuing, will have the right to purchase all, but not
     less than all, of the class G certificates.

   In each case, the purchase price will be equal to the Pool Balance of the
class G certificates plus accrued and unpaid interest on such Pool Balance to
the date of purchase, without premium, but including any other amounts due to
the class G certificateholders. Such purchase right may be exercised by any
class C certificateholder or by the Policy Provider. In each case, if prior to
the end of the ten-day period, any other class C certificateholder notifies the
purchasing certificateholder that the other certificateholder wants to
participate in such purchase, then such other certificateholder may join with
the purchasing certificateholder to purchase the class G certificates pro rata
based on the interest in the pass through trust held by each certificateholder.
The purchase rights of the certificateholders arising by reason of the
occurrence of a Triggering Event will expire 180 days after the Triggering
Event after which the Policy Provider's purchase rights in respect of the class
G certificates will become effective. (Trust Supplement, Section 4.01)

Termination of the Pass Through Trust

   Our obligations and those of the pass through trustee with respect to the
pass through trust will terminate upon the distribution to certificateholders
of all amounts required to be distributed to them pursuant to the pass through
trust agreement and the disposition of all property held in such pass through
trust. The pass through trustee will send to each certificateholder notice of
the termination of the pass through trust, the amount of the proposed final
payment and the proposed date for the distribution of such final payment. The
final payment to any certificateholder will be made only upon surrender of such
certificateholder's certificates at the office or agency of the pass through
trustee specified in such notice of termination. (Trust Supplement, Section
7.01)

The Pass Through Trustee

   The initial pass through trustee for the class G pass through trust will be
State Street Bank and Trust Company of Connecticut, National Association.

Book-Entry; Delivery and Form

   Upon issuance, the certificates will be represented by one or more fully
registered global certificates. Each global certificate will be deposited with,
or on behalf of, DTC and registered in the name of Cede & Co., the nominee of
DTC. DTC was created to hold securities for its participants and facilitate the
clearance and settlement of securities transactions between DTC Participants
through electronic book-entry changes in accounts of the DTC Participants,
thereby eliminating the need for physical movement of certificates. DTC
Participants include securities brokers and dealers, banks, trust companies and
clearing corporations and certain other organizations. Indirect access to the
DTC system is available to others such as banks, brokers, dealers and trust
companies that clear through or maintain a custodial relationship with a DTC
Participant, either directly or indirectly. Interests in a global certificate
may also be held through the Euroclear System and Clearstream Banking, societe
anonyme. See "Description of the Certificates--Book-Entry; Delivery and Form"
in the prospectus for a discussion of the book-entry procedures applicable to
the certificates and the limited circumstances under which definitive
certificates may be issued for the certificates.

                                      S-56
<PAGE>

   So long as such book-entry procedures are applicable, no certificateholder
will be entitled to receive a certificate representing such person's interest
in such certificates. Unless and until physical certificates are issued under
the limited circumstances described in this prospectus, all references to
actions by certificateholders refers to actions taken by DTC upon instructions
from DTC Participants, and all references herein to distributions, notices,
reports and statements to certificateholders refer, as the case may be, to
distributions, notices, reports and statements to DTC or Cede, as the
registered holder of such certificates, or to DTC Participants for distribution
to certificateholders in accordance with DTC procedures.

   According to DTC, the foregoing information with respect to DTC has been
provided to the financial community for informational purposes only and is not
intended to serve as a representation, warranty or contract modification of any
kind.

                      DESCRIPTION OF THE DEPOSIT AGREEMENT

   The following is a description of the particular terms of the Deposit
Agreement. The statements under this caption are summaries and do not purport
to be complete and are qualified in their entirety by reference to all the
provisions of the Deposit Agreement, that we will file as an exhibit to an
Annual Report on Form 10-K, a Quarterly Report on Form 10-Q, or to a Current
Report on Form 8-K with the SEC.

General

   Under the Escrow Agreement, the Escrow Agent with respect to the pass
through trust will enter into a Deposit Agreement with the Depositary. (Escrow
Agreement, Section 1.2) Under the Deposit Agreement, the Depositary will
establish separate deposit accounts in the name of the Escrow Agent. On the
Issuance Date, the proceeds relating to the offering of the certificates will
be deposited into the applicable Deposit Account by the Underwriters on behalf
of the Escrow Agent.

   On each Regular Distribution Date, the Depositary will pay to the Paying
Agent on behalf of the Escrow Agent, for distribution to the holders of Escrow
Receipts, an amount equal to interest accrued on the Deposits during the
relevant interest period at a rate per annum equal to the interest rate of the
certificates.

   In connection with the financing of each delivered aircraft during the
Delivery Period, the pass through trustee will request that the Escrow Agent
withdraw from the Deposits funds sufficient to enable the pass through trustee
to purchase the secured promissory notes issued with respect to such aircraft.
Accrued but unpaid interest on all such Deposits withdrawn will be paid on the
next Regular Distribution Date. Any portion of any Deposit withdrawn which is
not used to purchase such secured promissory note will be re-deposited by the
pass through trustee.

   The Deposits and interest paid on such Deposits will not be subject to the
subordination provisions of the Intercreditor Agreement and will not be
available to pay any other amount in respect of the certificates.

Unused Deposits

   The pass through trustee's obligations to purchase the secured promissory
notes issued with respect to each aircraft are subject to satisfaction of
conditions at the time of delivery, as set forth in the Note Purchase Agreement
and the Participation Agreements. See "Description of the Certificates--
Obligation to Purchase Secured Promissory Notes." Because the aircraft are
scheduled for delivery from time to time during the Delivery Period, no
assurance can be given that all such conditions will be satisfied at the time
of delivery for each aircraft. Moreover, the scheduled delivery date of any
aircraft is subject to delays in the manufacturing process and to the aircraft
manufacturer's right to postpone deliveries under the purchase agreement
between its affiliate and our parent. In such cases, the actual delivery date
of any aircraft may be delayed beyond its currently scheduled delivery date.
See "Description of the Aircraft and Appraisals--Deliveries of Aircraft."
Depending on the circumstances of the financing of each aircraft, the maximum
aggregate principal amount of secured promissory notes may not be issued.

                                      S-57
<PAGE>

   If any funds remain as Deposits with respect to the pass through trust after
the Delivery Period Termination Date, such funds will be withdrawn by the
Escrow Agent and distributed, with accrued and unpaid interest, to the holders
of Escrow Receipts. Any return of unused Deposits will be made after at least
15 days' prior written notice. Such distribution will include a premium payable
by us equal to the Deposit Make-Whole Premium with respect to the remaining
Deposits unless such deposits are returned because an aircraft is not delivered
prior to the Delivery Period Termination Date for any reason that is not due to
our fault or caused by our negligence. The Policy does not cover the Deposit
Make-Whole Premium.

Distribution upon Occurrence of a Triggering Event

   If a Triggering Event occurs prior to the Delivery Period Termination Date,
the Escrow Agent will withdraw any funds then held as Deposits and cause such
funds, with accrued and unpaid interest, but without any premium, to be
distributed to the holders of Escrow Receipts by the Paying Agent on behalf of
the Escrow Agent. Any return of unused deposits will be made after at least 15
days' prior written notice. Accordingly, if a Triggering Event occurs prior to
the Delivery Period Termination Date, the pass through trust will not purchase
secured promissory notes issued with respect to aircraft delivered after the
occurrence of such Triggering Event.

Depositary

   ABN AMRO Bank N.V., acting through its Chicago branch, will act as
Depositary.

   ABN AMRO Bank N.V. is a direct subsidiary of ABN AMRO Holding N.V., an
international multi-bank holding company. At December 31, 1999 ABN AMRO Holding
N.V. reported consolidated assets amounting to approximately $460 billion
(based on the exchange rate at December 31, 1999 of U.S. $1.00 to
(Euro)0.9951). The accounting principles applied in the preparation of the
financial statements of ABN AMRO Bank N.V. may not conform to U.S. generally
accepted accounting principles.

   ABN AMRO Bank N.V. has long-term unsecured debt ratings of Aa2 from Moody's
and AA from Standard & Poor's and short-term unsecured debt ratings of P-1 from
Moody's and A-1+ from Standard & Poor's.

   The Depositary has not been involved in the preparation of, and does not
accept responsibility for, this prospectus supplement.

Replacement of Depositary

   If the Depositary's short-term unsecured debt rating falls below A-1+ from
Standard & Poor's or P-1 from Moody's then we must, within 60 days of such
event, replace the Depositary with a new depositary bank that has short-term
unsecured debt ratings of at least A-1+ from Standard & Poor's and P-1 from
Moody's, or another depositary bank that will not result in a withdrawal or
downgrading of the rating of the certificates (without regard to any
downgrading of the rating of the Depositary being replaced, and without regard
to the Policy). In either case, we must obtain the written confirmation of the
Rating Agencies that the replacement of the Depositary will not cause a
downgrade or a withdrawal of the rating of the certificates (without giving
effect to the Policy).

                      DESCRIPTION OF THE ESCROW AGREEMENT

   The following is a description of the particular terms of the Escrow
Agreement. The statements under this caption are summaries only and do not
purport to be complete and are qualified in their entirety by reference to all
of the provisions of the Escrow Agreement that we will file as an exhibit to an
Annual Report on Form 10-K, a Quarterly Report on Form 10-Q, or to a Current
Report on Form 8-K with the SEC.

<PAGE>

   First Security Bank, National Association, as escrow agent in respect of the
pass through trust, State Street Bank and Trust Company of Connecticut,
National Association, as paying agent on behalf of the Escrow Agent, the pass
through trustee and the Underwriters will enter into an Escrow Agreement for
the benefit of the certificateholders of the pass through trust as holders of
the Escrow Receipts affixed to such certificates. The cash proceeds of the
offering of certificates will be deposited by the Underwriters on behalf of the
Escrow Agent (for the benefit of Receiptholders) with the Depositary as
Deposits.

   The Escrow Agent will permit the pass through trustee to cause funds to be
withdrawn from such Deposits on or prior to the Delivery Period Termination
Date so that the pass through trustee may purchase the related secured
promissory notes under the Note Purchase Agreement. In addition, the Escrow
Agent will direct the Depositary to pay interest on the Deposits accrued in
accordance with the Deposit Agreement to the Paying Agent for distribution to
the Receiptholders.

   The Escrow Agreement requires that the Paying Agent establish and maintain,
for the benefit of the Receiptholders, one or more non-interest-bearing Paying
Agent Accounts. The Paying Agent will deposit interest on Deposits and any
unused Deposits withdrawn by the Escrow Agent in the related Paying Agent
Account. The Paying Agent will distribute these amounts on a Regular
Distribution Date or Special Distribution Date, as appropriate. Each
Receiptholder, by its acceptance of an Escrow Receipt, is deemed to agree that
it will look solely to funds deposited in the Paying Agent Account for any
payment or distribution due to such Receiptholder under the Escrow Agreement
and the Escrow Receipt and that it will have no recourse against us, the pass
through trustee, the Paying Agent or the Escrow Agent, except as provided in
the Escrow Agreement and the pass through trust agreement.

   Upon receipt by the Depositary of the cash proceeds from this offering of
certificates, the Escrow Agent will issue one or more Escrow Receipts. An
Escrow Receipt will be affixed by the pass through trustee to each certificate.
Each Escrow Receipt will evidence a fractional undivided interest in amounts
from time to time deposited into the Paying Agent Account and will be limited
in recourse to amounts deposited into such account. An Escrow Receipt may not
be assigned or transferred except in connection with the assignment or transfer
of the certificate to which it is affixed. Each Escrow Receipt will be
registered by the Escrow Agent in the same name and manner as the certificate
to which it is affixed.

                     DESCRIPTION OF THE LIQUIDITY FACILITY

   The following description of the particular terms of the Liquidity Facility
and certain provisions of the Intercreditor Agreement supplements (and, to the
extent inconsistent therewith, replaces) the description of the general terms
and provisions relating to the Intercreditor Agreement and the description of
credit enhancements set forth in the prospectus.

   The statements under this caption are summaries and do not purport to be
complete and are qualified in their entirety by reference to all of the
provisions of the Liquidity Facility and the Intercreditor Agreement that we
will file as an exhibit to an Annual Report on Form 10-K, a Quarterly Report on
Form 10-Q, or a Current Report on Form 8-K with the SEC.

General

   The Liquidity Provider will enter into a revolving credit agreement, which
we will refer to as the Liquidity Facility, with the Subordination Agent with
respect to the certificates pursuant to which the Liquidity Provider will, if
necessary, make one or more advances to the Subordination Agent that will be
used solely to pay interest on the certificates when due at the Stated Interest
Rate for such certificates on up to three consecutive semiannual Regular
Distribution Dates. If interest payment defaults occur that exceed the amount
covered by or available under the Liquidity Facility, the certificateholders
will bear their allocable share of the deficiencies to the extent that there
are no other sources of funds (including funds from the Policy). Although
Bayerische Landesbank Girozentrale is the initial Liquidity Provider for the
pass through trust, Bayerische Landesbank Girozentrale may be replaced by one
or more other entities under certain circumstances.

                                      S-59
<PAGE>

   If class C certificates are issued, and such class C certificates have the
benefit of a liquidity facility, then the definitions of "Excess Reimbursement
Obligations," "Liquidity Expenses" and "Liquidity Obligations" will be
considered also to include the comparable excess reimbursement obligations,
liquidity expenses and liquidity obligations of the class C liquidity facility
and the definition of "Liquidity Facility" will be considered to include both
the class C and the class G Liquidity Facilities. There can be no assurance,
however, that the class C certificates, if or when issued, will be entitled to
the benefits of a liquidity facility or, if such class C certificates are
entitled to the benefits of a liquidity facility, that the terms of such
liquidity facility would be as described in this prospectus supplement.
Bayerische Landesbank Girozentrale has not agreed or committed to be the
liquidity provider for any class C certificates that may be issued, and the
liquidity provider for the class C certificates, if any are issued, may be
different from the Liquidity Provider for the class G certificates.

Drawings

   The aggregate amount available under the Liquidity Facility at February 5,
2001, the first Regular Distribution Date after all of the aircraft are
scheduled to have been delivered, assuming that secured promissory notes in the
maximum principal amount with respect to all aircraft are acquired by the pass
through trust and that all interest and principal due on or prior to February
5, 2001, is paid, will be $43,598,404.20.

   Except as otherwise provided below, the Liquidity Facility will enable the
Subordination Agent to make Interest Drawings under the Liquidity Facility on
any Distribution Date to pay interest then due and payable on the certificates
at the Stated Interest Rate to the extent that the amount, if any, available to
the Subordination Agent on such Distribution Date is not sufficient to pay such
interest. The maximum amount available to be drawn under the Liquidity Facility
on any Distribution Date to fund any shortfall of interest on the certificates
will not exceed the then Maximum Available Commitment under the Liquidity
Facility. (Liquidity Facility, Section 2.02(a); Intercreditor Agreement,
Section 3.6(a))

   The Liquidity Facility will not provide for drawings:

  .  To pay for principal of, or premium on, the certificates.

  .  To pay for any interest on the certificates in excess of the Stated
     Interest Rate or to pay for more than three consecutive semiannual
     installments of interest in excess of the Maximum Available Commitment
     under such Liquidity Facility.

  .  To pay for amounts payable with respect to the Deposits. (Liquidity
     Facility, Section 2.02; Intercreditor Agreement, Section 3.6).

   Each payment by the Liquidity Provider will reduce the Maximum Available
Commitment by an amount equal to the amount of such payment under the Liquidity
Facility, subject to reinstatement as described below. With respect to any
Interest Drawings under the Liquidity Facility, upon reimbursement of the
Liquidity Provider in full or in part for the amount of such Interest Drawings
plus interest thereon, the Maximum Available Commitment under the Liquidity
Facility will be reinstated to an amount not to exceed the then Required Amount
of the Liquidity Facility; provided, however, that the Liquidity Facility will
not be so reinstated at any time if (a) a Liquidity Event of Default has
occurred and is continuing and (b) less than 65% of the then aggregate
outstanding principal amount of all secured promissory notes are Performing
Secured Promissory Notes. (Liquidity Facility, Section 2.02(a)) With respect to
any other drawings under the Liquidity Facility, amounts available to be drawn
thereunder are not subject to reinstatement. Following the reduction of the
Pool Balance for the pass through trust, the maximum commitment of the
Liquidity Facility will be automatically reduced from time to time to an amount
equal to the Required Amount. (Liquidity Facility, Section 2.04(a))

                                      S-60

   If at any time the short-term unsecured debt rating of the Liquidity
Provider then issued by either Rating Agency is lower than the Threshold
Rating, the Liquidity Facility may be replaced by a Replacement Facility.
(Intercreditor Agreement, Sections 3.6(c) and 3.6(e)) The provider of any
Replacement Facility will have the same rights (including, without limitation,
priority distribution rights and rights as Controlling Party) under the
Intercreditor Agreement as the replaced Liquidity Provider.

   If the Liquidity Facility is not replaced with a Replacement Facility within
10 days after notice of the downgrading and as otherwise provided in the
Intercreditor Agreement, the Subordination Agent will make a Downgrade Drawing
in an amount equal to the then Maximum Available Commitment under the Liquidity
Facility. The Subordination Agent will deposit the proceeds of any Downgrade
Drawing in a Cash Collateral Account and will use these proceeds for the same
purposes and under the same circumstances and subject to the same conditions as
cash payments of Interest Drawings under the Liquidity Facility would be used.
(Liquidity Facility, Section 2.02(c); Intercreditor Agreement, Sections 3.6(c)
and 3.6(e))

   The Liquidity Facility will provide that the Liquidity Provider's
obligations under the Liquidity Facility will expire on the earliest of:

  .  364 days after the Issuance Date.

  .  The date on which the Subordination Agent delivers to the Liquidity
     Provider a certification that all of the certificates have been paid in
     full.

  .  The date on which the Subordination Agent delivers to the Liquidity
     Provider a certification that a Replacement Facility has been
     substituted for the Liquidity Facility.

  .  The fifth Business Day following receipt by the Subordination Agent of a
     Termination Notice from the Liquidity Provider (see "--Liquidity Events
     of Default").

  .  The date on which no amount is or may (by reason of reinstatement)
     become available for drawing under the Liquidity Facility.

  .  The date on which the Liquidity Provider makes available a Downgrade
     Drawing, a Non-Extension Drawing or a Final Drawing. (Liquidity
     Facility, Sections 1.01 and 2.04(b))

   The Liquidity Facility will provide that the scheduled expiration date of
the Liquidity Facility may be extended for additional 364-day periods by mutual
agreement.

   The Intercreditor Agreement will provide for the replacement of the
Liquidity Facility if it is scheduled to expire earlier than 15 days after the
Final Maturity Date if the Liquidity Facility is not extended prior to its then
scheduled expiration date. If the Liquidity Facility is not so extended or
replaced prior to its then scheduled expiration date, the Subordination Agent
will make a Non-Extension Drawing in an amount equal to the then Maximum
Available Commitment. The Subordination Agent will deposit the proceeds of the
Non-Extension Drawing in the Cash Collateral Account as cash collateral to be
used for the same purposes and under the same circumstances, and subject to the
same conditions, as cash payments of Interest Drawings under the Liquidity
Facility would be used. (Liquidity Facility, Section 2.02(b); Intercreditor
Agreement, Section 3.6(d))

   Subject to certain limitations, we may, at our option, arrange for a
Replacement Facility at any time to replace the Liquidity Facility (including
without limitation any Replacement Facility described in the following
sentence). In addition, the Liquidity Provider may, at its option, arrange for
a Replacement Facility (a) to replace a non-extended Liquidity Facility during
the period no earlier than 40 days and no later than 25 days prior to the then
scheduled expiration date of the Liquidity Facility or (b) after the short-term
unsecured debt rating of the Liquidity Provider is downgraded below the
applicable Threshold Rating (Intercreditor Agreement, Section 3.6(c) and (e)).
If any Replacement Facility is provided at any time after a Downgrade Drawing
or a Non-Extension Drawing under the Liquidity Facility, the funds with respect
to the Liquidity Facility on deposit in the Cash Collateral Account will be
returned to the Liquidity Provider being replaced. (Intercreditor Agreement,
Section 3.6(f))

                                      S-61
<PAGE>

   Upon receipt by the Subordination Agent of a Termination Notice with respect
to the Liquidity Facility from the Liquidity Provider, the Subordination Agent
will request a Final Drawing under the Liquidity Facility in an amount equal to
the then Maximum Available Commitment under the Liquidity Facility. The
Subordination Agent will hold the proceeds of such Final Drawing in the Cash
Collateral Account as cash collateral to be used for the same purposes and
under the same circumstances, and subject to the same conditions, as cash
payments of Interest Drawings under the Liquidity Facility would be used.
(Liquidity Facility, Section 2.02(d); Intercreditor Agreement, Section 3.6(i))

Reimbursement of Drawings

   The Subordination Agent must reimburse amounts drawn under the Liquidity
Facility by reason of an Interest Drawing, Final Drawing, Downgrade Drawing or
Non-Extension Drawing and interest on such drawings, but only to the extent
that the Subordination Agent has funds available to make such payments.
(Liquidity Facility, Sections 2.05, 2.06, 2.09)

 Interest Drawings and Final Drawings

   Amounts drawn by reason of an Interest Drawing or Final Drawing will be
immediately due and payable, together with interest on the amount of such
drawing. (Liquidity Facility, Section 2.05) From the date of each such drawing
to (but excluding) the third business day following the Liquidity Provider's
receipt of the notice of such Interest Drawing, interest will accrue at the
Base Rate plus 2% per annum. Thereafter, interest will accrue at LIBOR for the
applicable interest period plus 2% per annum. In the case of the Final Drawing,
however, the Subordination Agent may (x) convert the Final Drawing into a
drawing bearing interest at the Base Rate plus 2% per annum on the last day of
an interest period for such Drawing or (y) elect to maintain the Final Drawing
as a drawing bearing interest at the Base Rate plus 2% per annum. (Liquidity
Facility, Section 3.07)

 Downgrade Drawings and Non-Extension Drawings

   The amount drawn under the Liquidity Facility by reason of a Downgrade
Drawing or a Non-Extension Drawing will be treated as follows:

  .  Such amount will be released on any Distribution Date to the Liquidity
     Provider to the extent that such amount exceeds the Required Amount.

  .  Any portion of such amount withdrawn from the Cash Collateral Account to
     pay interest on the certificates will be treated in the same way as
     Interest Drawings.

  .  The balance of such amount will be invested in certain specified
     eligible investments.

   Any Downgrade Drawing or any Non-Extension Drawing under the Liquidity
Facility will bear interest (x) from the date of each such drawing to (but
excluding) the third business day following the Liquidity Provider's receipt of
notice of such drawing, at the Base Rate plus a specified margin on the
outstanding amount from time to time of such Downgrade or Non-Extension
Drawing, (y) thereafter until the date it is converted into a Final Drawing at
a rate equal to LIBOR for the applicable interest period plus a specified
margin on the outstanding amount from time to time of such Downgrade or Non-
Extension Drawing and (z) from and after the date, if any, on which it is
converted into a Final Drawing as described below under "--Liquidity Events of
Default," at a rate equal to LIBOR for the applicable Interest Period (or, as
described in the first paragraph under "--Interest Drawings and Final
Drawings," the Base Rate) plus 2% per annum. (Liquidity Facility, Section
2.06(a) and 3.07(b))

                                      S-62
<PAGE>

Liquidity Events of Default

   If any Liquidity Event of Default under the Liquidity Facility has occurred
and is continuing and less than 65% of the aggregate outstanding principal
amount of all secured promissory notes are Performing Secured Promissory Notes,
the Liquidity Provider may, in its discretion, give a Termination Notice.
Delivery to the Subordination Agent of a Termination Notice will have the
following consequences:

  .  The Liquidity Facility will expire on the fifth business day after the
     date on which such Termination Notice is received by the Subordination
     Agent.

  .  The Subordination Agent will promptly request, and the Liquidity
     Provider will make, a Final Drawing under the Liquidity Facility in an
     amount equal to the then Maximum Available Commitment under the
     Liquidity Facility.

  .  Any Drawing remaining unreimbursed as of the date of termination will be
     automatically converted into a Final Drawing under the Liquidity
     Facility.

  .  All amounts owing to the Liquidity Provider automatically will be
     accelerated. (Liquidity Facility, Section 6.01)

   Notwithstanding the foregoing, the Subordination Agent will be obligated to
pay amounts owing to the Liquidity Provider only to the extent the
Subordination Agent has funds to pay such amounts after giving effect to the
payments in accordance with the provisions set forth under "Description of the
Intercreditor Agreement--Priority of Distributions." (Liquidity Facility,
Section 2.09)

   Upon the circumstances described below under "Description of the
Intercreditor Agreement--Intercreditor Rights--Controlling Party," the
Liquidity Provider may become the Controlling Party with respect to the
exercise of remedies under the Indentures. (Intercreditor Agreement, Section
2.6(c))

Liquidity Provider

   The initial Liquidity Provider for the certificates will be Bayerische
Landesbank Girozentrale, a public law banking institution organized under the
laws of the Free State of Bavaria, Germany. Bayerische Landesbank Girozentrale
has short-term debt ratings of P-1 from Moody's and A-1+ from Standard &
Poor's. Other than the "Description of the Liquidity Facility--Liquidity
Provider" section of this prospectus supplement, the Liquidity Provider has not
been involved in the preparation of, and does not accept responsibility for,
this prospectus supplement.

                         DESCRIPTION OF THE POLICY AND
                         THE POLICY PROVIDER AGREEMENT

   The following summary of the terms of the Policy does not purport to be
complete and is qualified in its entirety by reference to the Policy, that we
will file as an exhibit to an Annual Report on Form 10-K, a Quarterly Report on
Form 10-Q or a Current Report on Form 8-K with the SEC.

The Policy

   The Policy Provider will issue a financial guaranty insurance policy in
favor of the Subordination Agent for the benefit of the pass through trustee
and holders of the certificates (and the holders of the Escrow Receipts
attached to such certificates, but only with respect to interest on the
deposits related to such Escrow Receipts). The Intercreditor Agreement directs
the Subordination Agent to make a drawing under the Policy under the following
five circumstances:

                                      S-63
<PAGE>

 Interest Drawings

   If on any Regular Distribution Date (other than the Final Maturity Date),
after giving effect to the subordination provisions of the Intercreditor
Agreement and to the application of any Prior Funds, the Subordination Agent
does not then have sufficient funds available for the payment of all amounts
due and owing in respect of accrued and unpaid interest on the certificates
and, without duplication, accrued and unpaid interest on any Deposit relating
to the Escrow Receipts attached to such certificates, in each case, at the
Stated Interest Rate on the Pool Balance of the certificates, the Subordination
Agent is to request a policy drawing under the Policy in an amount sufficient
to enable the Subordination Agent to pay such accrued interest on the
certificates or on such Deposit. (Intercreditor Agreement, Section 3.7(a))

 Proceeds Deficiency Drawing

   If, except as provided under "--No Proceeds Drawing" below, on any Special
Distribution Date established by the Subordination Agent by reason of its
receipt of a Special Payment constituting proceeds from the Disposition of or
in respect of any secured promissory note after giving effect to the
subordination provisions of the Intercreditor Agreement and to the application
of any Prior Funds, the Subordination Agent does not then have sufficient funds
available for a reduction in the outstanding Pool Balance of the certificates
by an amount equal to all of the outstanding principal amount of that secured
promissory note (determined immediately prior to the receipt of such proceeds)
plus accrued and unpaid interest on the amount of such reduction at the Stated
Interest Rate for the period from the immediately preceding Regular
Distribution Date to such Special Distribution Date, the Subordination Agent is
to request a policy drawing under the Policy in an amount sufficient to enable
the Subordination Agent to pay the amount of such reduction plus such accrued
interest. (Intercreditor Agreement, Section 3.7(c))

 No Proceeds Drawing

   On the first Business Day (which will be a Special Distribution Date) that
is 18 months after the last date on which full payment was made on a secured
promissory note as to which there has been a failure to pay principal or that
has been accelerated subsequent to such last date, if the Subordination Agent
has not received a Special Payment constituting proceeds from the Disposition
of or in respect of that secured promissory note, the Subordination Agent is to
request a policy drawing under the Policy in an amount equal to the then
outstanding principal amount of such secured promissory note plus accrued and
unpaid interest thereon at the Stated Interest Rate from the immediately
preceding Regular Distribution Date to that Special Distribution Date. The
Subordination Agent is to give prompt notice to the pass through trustee,
Liquidity Provider and Policy Provider setting forth the non-receipt of any
such Special Payment and establishing a Special Distribution Date (which date
shall be a Business Day), which notice is to be given not less than 25 days
prior to such Special Distribution Date. After the payment by the Policy
Provider in full of such amount of principal and accrued interest for such
policy drawing, the Subordination Agent will have no right to make any further
policy drawing in respect of any subsequent sale or other disposition of such
secured promissory note except for an "Avoidance Drawing" as described below.

   Notwithstanding the foregoing, the Policy Provider has the right at the end
of any such 18-month period, so long as no Policy Provider Default has occurred
and is continuing and so long as the Policy Provider has not defaulted in its
obligation, if any, to endorse the Policy as described in the next paragraph,
to elect instead, (a) to pay on the Special Distribution Date established
pursuant to the preceding paragraph an amount equal to any shortfall in the
scheduled principal and interest that came due on such secured promissory note
during such 18-month period (after giving effect to the application of funds,
if any, received from the Liquidity Facility and the Cash Collateral Account
attributable to such interest), (b) on each Regular Distribution Date that
occurs after such Special Distribution Date to permit drawings under the Policy
for an amount equal to the scheduled principal and interest that were to become
due on any such secured promissory note on the related payment date (without
regard to any acceleration thereof) until the establishment of an Election
Distribution Date or a Special Distribution Date elected by the Policy Provider
upon 20 days' notice, and (c) on any Election

                                      S-64
<PAGE>

Distribution Date or such Special Distribution Date elected by the Policy
Provider upon 20 days' notice, the Subordination Agent will be required, in
each case, to make a policy drawing for an amount equal to the then outstanding
principal balance of such secured promissory note and accrued interest thereon
at the Stated Interest Rate for the certificates from the immediately preceding
Regular Distribution Date to such Election Distribution Date or such Special
Distribution Date (after giving effect to the application of funds, if any,
received on such Election Distribution Date or such Special Distribution Date
from the Liquidity Facility or the Cash Collateral Account attributable to such
interest) less any policy drawings previously paid by the Policy Provider in
respect of principal on such secured promissory note. The Intercreditor
Agreement instructs the Subordination Agent to make each such drawing under the
Policy. Any such drawing shall not relieve the Policy Provider from any and all
obligations with respect to previous Policy Drawings.

   In addition, regardless of whether or not the Policy Provider makes a Policy
Provider Election, the Policy Provider will, at the end of such 18-month
period, endorse (if not already endorsed to so provide) the Policy to provide
for the payment to the Liquidity Provider of interest accruing on the Liquidity
Obligations in respect of the Liquidity Facility from and after the end of such
18-month period as and when such interest becomes due in accordance with such
Liquidity Facility. (Intercreditor Agreement, Section 3.7(a))

 Final Policy Drawing

   If on the Final Maturity Date after giving effect to the subordination
provisions of the Intercreditor Agreement and to the application of Prior
Funds, the Subordination Agent does not then have sufficient funds available
for the payment in full of the Final Distribution (calculated as at such date
but excluding any accrued and unpaid premium) the Subordination Agent is to
request a policy drawing under the Policy in an amount sufficient to enable the
Subordination Agent to pay the Final Distribution (calculated as at such date
but excluding any accrued and unpaid premium). (Intercreditor Agreement,
Section 3.7(d))

 Avoidance Drawing

   If at any time prior to the expiration of the Policy the Subordination Agent
has actual knowledge of the issuance of any Order, the Subordination Agent is
to give prompt notice to the pass through trustee, Liquidity Provider and
Policy Provider of such Order and prior to the expiration of the Policy,
request a policy drawing for an amount equal to the relevant Avoided Payment
and to deliver to the Policy Provider a copy of the documentation required by
the Policy with respect to such Order. To the extent that any portion of such
amount is to be paid to the Subordination Agent (and not to any receiver,
conservator, debtor-in-possession or trustee in bankruptcy as provided in the
Policy), the Subordination Agent shall establish as a Special Distribution Date
the date that is the earlier of three Business Days after the date of the
expiration of the Policy and the Business Day that immediately follows the 25th
day after that notice. (Intercreditor Agreement, Section 3.7(e))

General

   All requests by the Subordination Agent for a policy drawing are to be made
by it no later than 1:00 p.m. (New York City time) on (or in the case of any
policy drawing in respect of an Avoided Payment, at least three Business Days
prior to) the applicable Distribution Date and in the form required by the
Policy and delivered to the Policy Provider in accordance with the Policy.
(Intercreditor Agreement, Section 3.7) All proceeds of any policy drawing are
to be deposited by the Subordination Agent in the Policy Account and from there
paid to the pass through trustee (or Escrow Agent, as the case may be) for
distribution to the holders of the certificates (or the Escrow Receipts
attached to such certificates, as the case may be) without regard to the
subordination provisions of the Intercreditor Agreement. In the case of any
Avoided Payment, however, all or part of the policy drawing will be paid
directly to the bankruptcy receiver, conservator, debtor-in-possession or
trustee to the extent such amounts have not been paid by the
certificateholders. If any request for a policy drawing is rejected as not
meeting the requirements of the Policy, the Subordination Agent is to resubmit
such request so as to meet such requirements. (Intercreditor Agreement, Section
3.7(h))


                                      S-65
<PAGE>

   The Policy provides that if such a request for a policy drawing is properly
submitted or resubmitted it will pay to the Subordination Agent for deposit in
the Policy Account, the applicable payment under the Policy no later than 3:00
p.m. on the later of the relevant Distribution Date and the date the request is
received by the Policy Provider (if the request is received by 1:00 p.m. on
such date) or the next Business Day (if the request is received after that
time).

   Once any payment under the Policy is paid to the Subordination Agent (or, in
the case of payments made in respect of Escrow Receipts, the applicable Paying
Agent), the Policy Provider will have no further obligation in respect of those
payments. The Policy Provider will not be required or entitled to make any
payment under the Policy except at the times and in the amounts and under the
circumstances expressly set forth in the Policy.

   The Policy does not cover:

  .  Shortfalls, if any, attributable to the liability of the pass through
     trust, the pass through trustee, the Subordination Agent or the Paying
     Agent for withholding taxes, if any (including interest and penalties in
     respect of that liability).

  .  Any premium, prepayment penalty or accelerated payment which at any time
     may become due on or with respect to any certificate.

  .  Any failure of the Escrow Agent, Subordination Agent, Paying Agent or
     pass through trustee to make any payment due to the holders of the
     certificates (or Escrow Receipts attached to such certificates).

   The Policy Provider's obligation under the Policy will be discharged to the
extent that funds to be applied in respect of the certificates under and in
accordance with the Intercreditor Agreement are received by the Subordination
Agent or the Paying Agent for distribution to the pass through trustee and the
holders of certificates or Escrow Receipts attached to such certificates, as
applicable, whether or not the funds are properly distributed by the
Subordination Agent, the Paying Agent or the pass through trustee.

   The Policy is noncancellable. The Policy expires and terminates without any
action on the part of the Policy Provider or any other person on the date that
is one year and one day following the date on which the certificates have been
paid in full, unless an Insolvency Proceeding exists, in which case on the
later of (i) the date of the conclusion or dismissal of such Insolvency
Proceeding without continuing jurisdiction by the court in such Insolvency
Proceeding and (ii) the date on which the Policy Provider has made all payments
required to be made under the terms of the Policy in respect of an Avoided
Payment. No portion of the premium under the Policy is refundable for any
reason including payment, or provision being made for payment.

   The Policy will be construed under the laws of the State of New York.

The Policy Provider Agreement and the Policy Fee Letter

   We will enter into an insurance and indemnity agreement with the
Subordination Agent and the Policy Provider to be dated as of the date of the
issuance of the certificates containing, among other things, representations
and warranties by us and conditions precedent to the issuance of the Policy.
Pursuant to a fee letter between the Subordination Agent and the Policy
Provider (and acknowledged by us), the Subordination Agent agrees to pay the
Policy Provider a premium for the policy based upon the Pool Balance of the
certificates.

                   DESCRIPTION OF THE INTERCREDITOR AGREEMENT

   The following description of the particular terms of the Intercreditor
Agreement supplements (and, to the extent inconsistent with the prospectus,
replaces) the description of the general terms and provisions relating to the
Intercreditor Agreement set forth in the prospectus. The statements made under
the caption are summaries

                                      S-66
<PAGE>

and do not purport to be complete and are qualified in their entirety by
reference to all of the provisions of the Intercreditor Agreement, that we will
file as an exhibit to an Annual Report on Form 10-K, a Quarterly Report on Form
10-Q or a current report on Form 8-K with the SEC.

Intercreditor Rights

 General

   The Intercreditor Agreement will be among the pass through trustee, the
Liquidity Provider, the Policy Provider and the Subordination Agent. The
secured promissory notes will be registered in the name of the Subordination
Agent or its nominee as agent and trustee for the pass through trustee solely
for the purpose of facilitating the enforcement of the other provisions of the
Intercreditor Agreement.

 Controlling Party

   With respect to any Indenture at any given time, so long as no Indenture
Default (which, with respect to leased aircraft, has not been cured by the
applicable Owner Trustee or Owner Participant) has occurred and is continuing
under such Indenture, the Loan Trustee under such Indenture will be directed in
taking, or refraining from taking, any action under such Indenture or with
respect to the secured promissory notes issued under such Indenture by the
holders of at least a majority of the outstanding principal amount of the
secured promissory notes issued under such Indenture. For so long as the
Subordination Agent is the registered holder of the secured promissory notes,
the Subordination Agent will act with respect to the preceding sentence in
accordance with the directions of the pass through trustee (or, if class C
certificates have been issued, the pass through trustee for whom the secured
promissory notes issued under such Indenture are held as trust property, to the
extent constituting, in the aggregate, directions with respect to the required
principal amount of secured promissory notes), except that so long as the final
distributions on the certificates have not been paid or any Policy Provider
Obligations remain outstanding (and no Policy Provider Default exists and so
long as the Policy Provider has endorsed the Policy (if so required) in the
manner described in the final paragraph in "Description of the Policy and the
Policy Provider Agreement--The Policy--No Proceeds Drawing"), the Subordination
Agent will request directions from the Policy Provider rather than the pass
through trustee and shall vote in accordance with the directions of the Policy
Provider. (Intercreditor Agreement, Section 2.6(a) and Section 9.1(b))

   At any time an Indenture Default has occurred and is continuing under an
Indenture (which, with respect to leased aircraft, has not been cured by the
applicable Owner Trustee or Owner Participant), the Loan Trustee under such
Indenture will be directed in taking, or refraining from taking, any action
under such Indenture or with respect to the secured promissory notes issued
under such Indenture, including acceleration of such secured promissory notes
or foreclosing the lien on the related aircraft, by the Controlling Party,
subject to the limitations described below. (Intercreditor Agreement, Section
2.6(a)) Notwithstanding the foregoing, no amendment, modification, consent or
waiver will, without the consent of the Liquidity Provider and Policy Provider,
reduce the amount of rent, supplemental rent or termination values payable by
us under any lease or reduce the amount of principal or interest payable by us
under any secured promissory note issued under any Owned Aircraft Indenture.
(Intercreditor Agreement, Section 9.1(b)). See "Description of the
Certificates--Indenture Defaults and Certain Rights Upon an Indenture Default"
for a description of the rights of the certificateholders to direct the pass
through trustee.

   The controlling party will be:

  .  the policy provider, until final distributions of the aggregate
     outstanding balance of the certificates, together with accrued and
     unpaid interest, are made to the holders of the certificates and no
     obligations owing to the Policy Provider remain outstanding; or,

  .  if a Policy Provider Default has occurred and is continuing or the
     Policy Provider is required to but has failed to endorse the Policy in
     the manner described in the final paragraph in "Description of the
     Policy and the Policy Provider Agreement--The Policy--No Proceeds
     Drawing," then the pass through trustee until payment of final
     distributions to the holders of the certificates, then,

  .  if class C certificates have been issued, the class C pass through
     trustee.

                                      S-67
<PAGE>

   If the Liquidity Provider is not then in default in its obligations to make
any advance under the Liquidity Facility, the Liquidity Provider will have the
right to become the Controlling Party with respect to any Indenture at any time
after 18 months from the earliest to occur of (x) the date on which the entire
available amount under the Liquidity Facility has been drawn (for any reason
other than a Downgrade Drawing or a Non-Extension Drawing) and remains
unreimbursed, (y) the date on which the entire amount of any Downgrade Drawing
or Non-Extension Drawing has been withdrawn from the Cash Collateral Account to
pay interest on the certificates and remains unreimbursed and (z) the date on
which all secured promissory notes have been accelerated (provided that if such
acceleration occurs prior to the Delivery Period Termination Date, the
aggregate principal amount thereof exceeds $250 million) provided that if the
Policy Provider pays to the Liquidity Provider all outstanding Drawings,
together with accrued interest on such Drawings, in respect of the Liquidity
Facility including all interest accrued thereon to such date, the Policy
Provider will remain the Controlling Party so long as no Policy Provider
Default has occurred and is continuing (in which case such Liquidity Provider,
if it so elects and if Liquidity Obligations owing to it remain outstanding
(or, if it does not so elect or if no such Liquidity Obligations remain
outstanding, the pass through trustee), will become the Controlling Party).
(Intercreditor Agreement, Section 2.6(c)) If class C certificates are issued
and such class C certificates have the benefit of a liquidity facility, then
the liquidity provider with the larger amount owed to it will be entitled to
make the election in the immediately preceding sentence. In addition, if class
C certificates are issued, the Policy Provider will be required to pay the
liquidity provider for the class C trust all comparable drawings, together with
accrued interest on such drawings, owing under any liquidity facility for the
class C pass through trust.

   For purposes of giving effect to the rights of the Controlling Party, the
pass through trustee (other than the Controlling Party) will irrevocably agree,
and the certificateholders (other than the certificateholders represented by
the Controlling Party) will be deemed to agree by virtue of their purchase of
certificates, that the Subordination Agent, as record holder of the secured
promissory notes, will exercise its voting rights in respect of the secured
promissory notes as directed by the Controlling Party. (Intercreditor
Agreement, Section 2.6(b)) For a description of certain limitations on the
Controlling Party's rights to exercise remedies, see "Description of the
Secured Promissory Notes--Remedies."

 Sale of Secured Promissory Notes or Aircraft

   Upon the occurrence and during the continuation of any Indenture Default
under any Indenture, the Controlling Party will be entitled to accelerate and,
subject to the provisions of the immediately following sentence, sell all (but
not less than all) of the secured promissory notes issued under such Indenture
to any person. So long as any certificates are outstanding, during nine months
after the earlier of (x) the acceleration of the secured promissory notes under
any Indenture and (y) our bankruptcy or insolvency, without the consent of the
pass through trustee, no aircraft subject to the lien of such Indenture or such
secured promissory notes may be sold, if the net proceeds from such sale would
be less than the Minimum Sale Price for such aircraft or such secured
promissory notes. In addition, with respect to any leased aircraft, the amount
and payment dates of rentals payable by us under the lease for such leased
aircraft may not be adjusted, if, as a result of such adjustment, the
discounted present value of all such rentals would be less than 75% of the
discounted present value of the rentals payable by us under such lease before
giving effect to such adjustment. (Intercreditor Agreement, Section 4.1)

Priority of Distribution

 Before a Triggering Event

   So long as no Triggering Event has occurred, payments in respect of the
secured promissory notes and certain other payments received on any
Distribution Date will be promptly distributed by the Subordination Agent on
such Distribution Date in the following order of priority:

  .  to the Liquidity Provider to the extent required to pay the Liquidity
     Expenses and to the Policy Provider to the extent required to pay the
     Policy Expenses, pro rata on the basis of the Liquidity Expenses and
     Policy Expenses then due;

                                      S-68

  .  to the Liquidity Provider and to the Policy Provider, pro rata, to the
     extent required to pay interest accrued on the Liquidity Obligations (as
     determined after giving effect to payments made by the Policy Provider
     to the Liquidity Provider in respect of drawings under the Liquidity
     Facility) and on certain Policy Provider Obligations (as provided in the
     definition of Policy Provider Obligations), respectively and, if the
     Policy Provider has elected to pay to the Liquidity Provider all
     outstanding drawings and interest thereon owing to the Liquidity
     Provider under the Liquidity Facility, to reimburse the Policy Provider
     for the amount of such payment made to the Liquidity Provider
     attributable to interest accrued on such drawings;

  .  to the Liquidity Provider to the extent required to pay or reimburse the
     Liquidity Provider for the Liquidity Obligations (other than amounts
     payable pursuant to the two preceding clauses and/or, if applicable, to
     replenish each Cash Collateral Account up to the Required Amount and, if
     the Policy Provider has elected to pay to the Liquidity Provider all
     outstanding drawings and interest thereon owing to the Liquidity
     Provider under the Liquidity Facility, to reimburse the Policy Provider
     for the amount of such payment made to the Liquidity Provider in respect
     of principal of drawings under the Liquidity Facility, pro rata;

  .  to the pass through trustee to the extent required to pay Expected
     Distributions on the certificates;

  .  to the Policy Provider to the extent required to pay or reimburse any
     Policy Provider Obligations (other than amounts payable pursuant to the
     first three clauses above and any Excess Reimbursement Obligations);

  .  if any class C certificates have been issued, to the pass through
     trustee for the class C pass through trust, to the extent required to
     pay "expected distributions" (to be defined in a manner equivalent to
     the definition of "Expected Distribution" for the class G certificates)
     on the class C certificates;

  .  to the Policy Provider to the extent required to pay any Excess
     Reimbursement Obligations; and

  .  to the Subordination Agent and the pass through trustee for the payment
     of certain fees and expenses.

 After a Triggering Event

   Subject to the terms of the Intercreditor Agreement, upon the occurrence of
a Triggering Event and at all times after such Triggering Event, all funds
received by the Subordination Agent in respect of the secured promissory notes
and certain other payments will be promptly distributed by the Subordination
Agent in the following order of priority:

  .  to the Subordination Agent, the pass through trustee, any
     certificateholder or the Policy Provider, pro rata, to the extent
     required to pay certain out-of-pocket costs and expenses actually
     incurred by the Subordination Agent, the pass through trustee or the
     Policy Provider or to reimburse any certificateholder, the Policy
     Provider or the Liquidity Provider in respect of payments made to the
     Subordination Agent or the pass through trustee in connection with the
     protection or realization of the value of the secured promissory notes
     or any property held in any Trust Indenture Estate or any Collateral;

  .  to the Liquidity Provider to the extent required to pay the Liquidity
     Expenses and to the Policy Provider to the extent required to pay the

  .  to the Liquidity Provider and the Policy Provider, pro rata, to the
     extent required to pay interest accrued on the Liquidity Obligations (as
     determined after giving effect to certain payments by the Policy
     Provider to the Liquidity Provider) and on certain Policy Provider
     Obligations (as provided in the definition of Policy Provider
     Obligations), respectively and, if the Policy Provider has elected to
     pay to the Liquidity Provider all outstanding drawings and interest
     thereon owing to the Liquidity Provider under the Liquidity Facility, to
     reimburse the Policy Provider for the amount of such payment made to the
     Liquidity Provider attributable to interest accrued on such drawings;

                                      S-69
<PAGE>

  .  to the Liquidity Provider to the extent required to pay the outstanding
     amount of all Liquidity Obligations (as determined after giving effect
     to payments by the Policy Provider to the Liquidity Provider in respect
     of principal of drawings under the Liquidity Facility) with respect to
     the Liquidity Facility, unless (x) less than 65% of the aggregate
     outstanding principal amount of all secured promissory notes are
     Performing Secured Promissory Notes and a Liquidity Event of Default has
     occurred and is continuing under the Liquidity Facility or (y) a Final
     Drawing has occurred under the Liquidity Facility, then payments are
     made first to replenish the Cash Collateral Account up to the Required
     Amount (less the amount of any repayments of Interest Drawings under the
     Liquidity Facility while sub-clause (x) of this clause is applicable)
     and, if the Policy Provider has elected to pay to the Liquidity Provider
     all outstanding drawings and interest thereon owing to the Liquidity
     Provider under the Liquidity Facility, to reimburse the Policy Provider
     for the amount of such payment made to the Liquidity Provider in respect
     of principal of drawings under the Liquidity Facility, pro rata;

  .  to the Subordination Agent, the pass through trustee or any
     certificateholder to the extent required to pay certain fees, taxes,
     charges and other amounts payable;

  .  to the pass through trustee to the extent required to pay Adjusted
     Expected Distributions on the certificates;

  .  to the Policy Provider to the extent required to pay the Policy Provider
     Obligations (other than amounts payable pursuant to the first four
     clauses above, any Excess Reimbursement Obligations and any amounts
     payable under the Policy Fee Letter);

  .  if class C certificates have been issued, to the pass through trustee
     for the class C trust, to the extent required to pay "adjusted expected
     distributions" (to be defined in a manner equivalent to the definition
     of "Adjusted Expected Distributions" for the class G certificates); and

  .  to the Policy Provider to pay any Excess Reimbursement Obligations and
     amounts due under the Policy Fee Letter.

   After a Triggering Event occurs and any secured promissory note becomes a
Non-Performing Secured Promissory Note, the Subordination Agent will obtain LTV
Appraisals of all of the aircraft securing the secured promissory notes as soon
as practicable and additional LTV Appraisals on or prior to each anniversary of
the date of such initial LTV Appraisals. If the Controlling Party reasonably
objects to the appraised value of the aircraft shown in such LTV Appraisals,
the Controlling Party has the right to obtain or cause to be obtained
substitute LTV Appraisals (including LTV Appraisals based upon physical
inspection of such aircraft). (Intercreditor Agreement, Section 4.1(a))

   Interest Drawings under the Liquidity Facility and withdrawals from the Cash
Collateral Account, in each case in respect of interest on the certificates of
any pass through trust, will be distributed to the pass through trustee for
such pass through trust, and drawings under the Policy will be distributed by
the class G pass through trustee, notwithstanding the priority of distributions
set forth in the Intercreditor Agreement and otherwise described in this
prospectus supplement. (Intercreditor Agreement, Sections 3.6 and 3.7)

The Subordination Agent

   State Street Bank and Trust Company of Connecticut, National Association,
will be the "Subordination Agent" under the Intercreditor Agreement. We and our
affiliates may from time to time enter into banking and trustee relationships
with the Subordination Agent and its affiliates. The Subordination Agent's
address is State Street Bank and Trust Company of Connecticut, National
Association, 225 Asylum Street, Hartford, Connecticut 06103.

   The Subordination Agent may resign at any time, in which event a successor
Subordination Agent will be appointed as provided in the Intercreditor
Agreement. The Controlling Party may remove the Subordination

                                      S-70
<PAGE>

Agent for cause as provided in the Intercreditor Agreement. In such
circumstances, a successor Subordination Agent will be appointed as provided in
the Intercreditor Agreement. Any resignation or removal of the Subordination
Agent and appointment of a successor Subordination Agent does not become
effective until acceptance of the appointment by the successor Subordination
Agent. (Intercreditor Agreement, Section 8.1)

                 DESCRIPTION OF THE AIRCRAFT AND THE APPRAISALS

The Aircraft

   The aircraft consist of 16 Airbus Model A319-100 aircraft and four Airbus
Model A320-200 aircraft, seven of which have been delivered, or are expected to
be delivered prior to the issuance of the certificates, by the manufacturer to
us and the remaining 13 of which are scheduled for delivery through October
2000 (the "Delivery Period"). The aircraft have been designed to be in
compliance with Stage 3 noise level standards, which are the most restrictive
regulatory standards currently in effect in the United States for aircraft
noise abatement.

   The Airbus Model A319-100 and Airbus Model A320-200 aircraft both are
capable of flying from our major Northeast United States hubs to West Coast
markets. The seating capacity of the A319-100 aircraft is approximately 120
passengers. The engine type utilized on the Airbus Model A319-100 aircraft will
be the CFM International, Inc. CFM-56-5. The seating capacity of the Airbus
Model A320-200 aircraft is approximately 142 passengers. The engine type
utilized on the Airbus Model A320-200 aircraft will be the CFM International,
Inc. CFM-56-5.

--------
(1) The actual delivery dates for the first four Airbus A319 aircraft and the
    first Airbus A320 aircraft are set forth above. The delivery date for the
    remaining aircraft is the date that we expect the aircraft to be delivered
    by the manufacturer. This date may be delayed or accelerated. We have the
    option to substitute other aircraft if the delivery of any aircraft is
    expected to be delayed for more than 30 days after the month scheduled for
    delivery of that aircraft or beyond the delivery period termination date.
    The delivery period termination date is the earlier of (i) the date all
    aircraft described in this prospectus supplement are financed, and (ii)
    March 1, 2001. We may take delivery of an aircraft and finance that
    aircraft under this offering up to 180 days after such delivery (or such
    longer period after such delivery as we may elect with approval from the
    Rating Agencies, but in any event, not later than March 1, 2001). See "--
    Substitute Aircraft."
(2) The appraised base value of each aircraft set forth above is the lesser of
    the mean and median base values of such aircraft as appraised by three
    independent appraisal and consulting firms, and projected for aircraft not
    yet delivered as of the scheduled delivery month of each aircraft. Such
    appraisals are based upon varying assumptions (which assumptions may not
    reflect current market conditions) and methodologies. An appraisal is only
    an estimate of value and should not be relied upon as a measure of
    realizable value. See "Risk Factors--Risk Factors Relating to the
    Certificates and the Offering--Appraisals and Realizable Value of
    Aircraft."

   For purposes of the foregoing chart AISI, AvSolutions and MBA were asked to
provide their respective opinions as to the appraised base value of each
aircraft as of the date specified on the first page of such appraisal attached
as Appendix I and as projected as of the scheduled delivery month of each such
aircraft. As part of this process, all three Appraisers performed "desk-top"
appraisals without any physical inspection of the aircraft. The appraisals are
based on various assumptions and methodologies, which vary among the appraisers
and may not reflect current market conditions that could affect the fair market
value of the aircraft. The Appraisers have delivered letters summarizing their
respective appraisals. Copies of such letters are attached to this prospectus
supplement as Appendix I. We refer you to such summaries for the definition of
appraised base value and a discussion of the assumptions and methodologies used
in each of the appraisals.

                                      S-72
<PAGE>

   An appraisal is only an estimate of value, is not indicative of the price at
which an aircraft may be purchased from the manufacturer and should not be
relied upon as a measure of sales value. The proceeds realized upon a sale of
any aircraft may be less than the appraised value of such aircraft. The value
of the aircraft upon the exercise of remedies under the applicable Indenture
will depend on market and economic conditions, the availability of buyers, the
condition of the aircraft and other similar factors. Accordingly, there can be
no assurance that the proceeds realized upon any such exercise with respect to
the secured promissory notes and the aircraft pursuant to the applicable
Indenture would equal the appraised value of such aircraft or be sufficient to
satisfy in full payments due on the secured promissory notes issued under such
Indenture or the certificates.

Deliveries of Aircraft

   Five of the aircraft have been delivered and the remaining aircraft are
scheduled for delivery through October 2000 under a purchase agreement between
our parent and an affiliate of Airbus. See the table under "--The Appraisals"
for the actual or scheduled month of delivery of each aircraft. Under the
purchase agreement, delivery of an aircraft may be delayed due to "Excusable
Delay," which is defined to include delays in delivery or failure to deliver or
perform due to causes reasonably beyond Airbus' or any associated contractor's
control or not occasioned by Airbus' or any associated contractor's fault,
misconduct or negligence. We cannot predict whether adjustments in such
schedule will be required.

   The Note Purchase Agreement provides that the Delivery Period will expire on
the Delivery Period Termination Date.

   If delivery of any aircraft is delayed by more than 30 days after the month
scheduled for delivery or beyond March 1, 2001, we have the right to replace
such aircraft with a substitute aircraft, subject to certain conditions. See
"--Substitute Aircraft." If delivery of any aircraft is delayed beyond the
Delivery Period Termination Date and we do not exercise our right to replace
such aircraft with a substitute aircraft, there will be unused Deposits that
will be distributed to certificateholders together with accrued and unpaid
interest thereon and, in certain circumstances, a Deposit Make-Whole Premium.
See "Description of the Deposit Agreements--Unused Deposits."

Substitute Aircraft

   If the delivery date for any aircraft is delayed (a) more than 30 days after
the month scheduled for delivery, or (b) beyond March 1, 2001, we may identify
for delivery a substitute aircraft for such aircraft meeting the following
conditions:

  .  a substitute aircraft must be the same model (either A319 or A320, as
     the case may be) as the aircraft for which delivery was delayed and
     delivered by the manufacturer to US Airways after January 31, 2000.

  .  we will be obligated to obtain written confirmation from each Rating
     Agency that substituting such substitute aircraft for the replaced
     aircraft will not result in a withdrawal, suspension or downgrading of
     the ratings of the certificates.

                  DESCRIPTION OF THE SECURED PROMISSORY NOTES

   The following description of the terms of the secured promissory notes
supplements (and, to the extent inconsistent with the prospectus, replaces) the
description of the general terms and provisions relating to the secured
promissory notes, the Indentures, the leases, the Participation Agreements, the
Leased Aircraft Trust Agreements and the Note Purchase Agreement set forth in
the prospectus. The summaries make use of terms defined in and are qualified in
their entirety by reference to all of the provisions of the secured promissory
notes, the Indentures, the leases, the Participation Agreements, the Leased
Aircraft Trust Agreements and the Note Purchase Agreement, forms of which will
be filed as exhibits to an Annual Report on Form 10-K, a Quarterly Report on
Form 10-Q or a Current Report on Form 8-K that we will file with the SEC.

General

   The secured promissory notes are expected to be issued for each aircraft in
a single series: the series G secured promissory notes. We may elect to issue a
second series of secured promissory notes, which will be designated "series C
secured promissory notes," with respect to any aircraft described in this
prospectus supplement. The purchase price for any such series C secured
promissory notes will be funded from sources other than this offering. See
"Description of the Certificates--Possible Issuance of Class C Certificates."

   The secured promissory notes with respect to each leased aircraft will be
issued under a separate Leased Aircraft Indenture between First Security Bank,
National Association, as Owner Trustee, and State Street Bank and Trust Company
of Connecticut, National Association, as Loan Trustee.

   The secured promissory notes with respect to each owned aircraft will be
issued under a separate Owned Aircraft Indenture between us and State Street
Bank and Trust Company of Connecticut, National Association, as Loan Trustee.
The secured promissory notes with respect to each owned aircraft will be
secured obligations of US Airways.

   The Indentures will not provide for defeasance, or discharge upon deposit of
cash or certain obligations of the United States, notwithstanding the
description of defeasance in the prospectus.

   In the case of a leased aircraft, we will lease each aircraft from the
related Owner Trustee under a separate lease. Under each lease and the related
Aircraft Operative Agreements, we will, in general, be obligated to make or
cause to be made rental and other payments or advances to the related Loan
Trustee on behalf of the related Owner Trustee. Such rental and other payments
or advances will be at least sufficient to pay in full when due all payments
required to be made on the secured promissory notes issued with respect to such
leased aircraft. The secured promissory notes issued with respect to the leased
aircraft will not be direct obligations of US Airways and we will not guarantee
payment or performance of the leased aircraft notes. Our obligations under each
lease and the related Aircraft Operative Agreements will be general unsecured
obligations.

   If any series C secured promissory notes are issued, those notes issued in
respect of an aircraft will be subordinated in right of payment to series G
secured promissory notes issued in respect of such aircraft. (Leased Aircraft
Indentures, Section 2.15 and Article III; Owned Aircraft Indentures, Section
2.15 and Article III) On each scheduled payment date, payments of interest and
principal due on series G secured promissory notes issued in respect of an
aircraft will be made prior to payments of interest and principal due on series
C secured promissory notes, if any are issued, issued in respect of the same
aircraft. (Leased Aircraft Indentures, Article III; Owned Aircraft Indentures,
Article III)

Principal and Interest Payments

   Subject to the provisions of the Intercreditor Agreement, interest paid on
the secured promissory notes held in the pass through trust will be passed
through to the certificateholders on the dates and at the rate per annum set
forth on the cover page of this prospectus supplement until the final expected
Regular Distribution Date. Subject to the provisions of the Intercreditor
Agreement, principal paid on the secured promissory notes held in the pass
through trust will be passed through to the certificateholders in scheduled
amounts on the dates set forth in this prospectus supplement until the final
expected Regular Distribution Date.

                                      S-74
<PAGE>

   Interest will be payable on the unpaid principal amount of each secured
promissory note at the rate applicable to such secured promissory note on
February 5 and August 5 of each year, commencing on the first such date to
occur after initial issuance of such secured promissory note. Such interest
will be computed on the basis of a 360-day year of twelve 30-day months.
Overdue amounts of principal, Make-Whole Premium and interest on such series of
secured promissory notes will bear interest at a rate equal to at least 1% per
annum over the applicable interest rate on such series of secured promissory
notes.

   Scheduled principal payments on the secured promissory notes will be made on
February 5 and August 5 in certain years, commencing on August 5, 2003. See
"Description of the Certificates--Pool Factors" for a discussion of the
scheduled payments of principal of the secured promissory notes and possible
revisions to such scheduled payments.

   The final payment made under each secured promissory note will be in an
amount sufficient to discharge in full the unpaid principal amount, Make-Whole
Premium (if any) and to the extent permitted by law, interest and any other
amounts payable but unpaid with respect to such secured promissory note.

   If any date scheduled for a payment of principal, premium (if any) or
interest with respect to the secured promissory notes is not a Business Day,
such payment will be made on the next succeeding Business Day with the same
force and effect as if made on such scheduled payment date and without any
additional interest.

Redemption

 Mandatory Redemption

   If an Event of Loss occurs with respect to an aircraft and we do not replace
such aircraft under the related lease (in the case of a leased aircraft) or
under the related Owned Aircraft Indenture (in the case of an owned aircraft),
the secured promissory notes issued with respect to such aircraft will be
redeemed, in whole, in each case at a price equal to the aggregate unpaid
principal amount thereof, together with accrued interest thereon, to the date
of redemption and other amounts payable to the holders of the secured
promissory notes under the applicable Indenture and Participation Agreement,
but without premium. (Indentures, Section 2.10(a)). Such redemption will be on
a Special Distribution Date.

   If we exercise our right to terminate a lease under our voluntary
termination, early buyout or burdensome buyout options under such lease, the
secured promissory notes relating to the applicable leased aircraft will be
redeemed (unless we elect to assume the secured promissory notes on a full
recourse basis), in whole, on a Special Distribution Date at a price equal to
the aggregate unpaid principal amount thereof, together with accrued interest
thereon to, but not including, the date of redemption and other amounts payable
to the holders of the secured promissory notes under the applicable Indenture
and Participation Agreement, plus a Make-Whole Premium. (Leased Aircraft
Indentures, Section 2.10(b)) See "--The Leases--Lease Termination."

 Voluntary Redemption

   All, but not less than all, of the secured promissory notes issued with
respect to a leased aircraft may be redeemed prior to maturity with our consent
at a price equal to 100% of the unpaid principal thereof, together with accrued
interest thereon to, but not including, the date of redemption and all other
amounts payable to the holders of the secured promissory notes under the
applicable Indenture and Participation Agreement, plus, a Make-Whole Premium.
(Leased Aircraft Indentures, Section 2.11)

   All, but not less than all, of the secured promissory notes issued with
respect to an owned aircraft may be redeemed prior to maturity at any time at
our option at a price equal to 100% of the unpaid principal amount of the
secured promissory notes being redeemed, together with accrued and unpaid
interest on those secured promissory notes to, but not including the date of
redemption and all other amounts payable to the holders of the secured
promissory notes under the applicable Indenture and Participation Agreement,
plus a Make Whole Premium. (Owned Aircraft Indentures, Section 2.11)

                                      S-75
<PAGE>

   If notice of such a redemption is given in connection with a refinancing of
secured promissory notes with respect to an aircraft, such notice may be
revoked at any time not later than three days prior to the proposed redemption
date. (Indentures, Section 2.12)

   If, with respect to a leased aircraft, (a) one or more Lease Events of
Default have occurred and are continuing or (b) the secured promissory notes
with respect to such aircraft have been declared due and payable by the
applicable Loan Trustee or the Loan Trustee with respect to such secured
promissory notes takes action or notifies the applicable Owner Trustee that it
intends to take action to foreclose the lien of the related Leased Aircraft
Indenture or otherwise commence the exercise of any significant remedy under
such Leased Aircraft Indenture or the related lease or if certain events occur
in a bankruptcy proceeding involving us, then in each case all, but not less
than all, of the secured promissory notes issued with respect to such leased
aircraft may be purchased by the related Owner Trustee or Owner Participant on
the applicable purchase date at a price equal to the aggregate unpaid principal
amount of the secured promissory notes being purchased, plus accrued and unpaid
interest on the amount of those secured promissory notes to, but not including
the date of such purchase, but without Make-Whole Premium (except under the
limited circumstances described in the following sentence), plus all other
amounts payable to the holders of the secured promissory notes under the
applicable Leased Aircraft Indenture and Participation Agreement. The purchase
price for the secured promissory notes will include a Make-Whole Premium if an
Owner Trustee or an Owner Participant purchases the secured promissory notes at
a time when (x) a Lease Event of Default under the applicable Lease has
occurred and has been continuing under the Lease for less than 120 days and (y)
the secured promissory notes have not been declared due and payable by the
applicable Loan Trustee, and the applicable Loan Trustee has not taken, and has
not notified the applicable Owner Trustee that it intends to take, any action
to foreclose the lien of the related Leased Aircraft Indenture or otherwise
commence the exercise of any significant remedy under the Leased Aircraft
Indenture or the related lease and certain events have not occurred in a
bankruptcy proceeding involving us. (Leased Aircraft Indentures, Section 2.14)

   We as owner of an owned aircraft, have no comparable right under the Owned
Aircraft Indentures to purchase the secured promissory notes under the
circumstances described in the preceding paragraphs.

Security

   The secured promissory notes issued with respect to each aircraft will be
secured by a first priority security interest in the aircraft, the related
lease and all rent under such lease (with respect to leased aircraft), as well
as all rents, profits and other income of such aircraft, certain rights under
the aircraft purchase agreement between our parent and an affiliate of the
aircraft manufacturer, all requisition proceeds with respect to such aircraft,
all insurance proceeds with respect to the aircraft (other than proceeds under
third party liability policies and under policies maintained by the Owner
Participant), all monies and securities deposited with the related Loan
Trustee, and all proceeds of the foregoing. (Indentures, Granting Clause)

   In the case of a Leased Aircraft Indenture, the related Loan Trustee may not
exercise the Owner Trustee's rights under the related lease except such Owner
Trustee's right to receive rent, unless an Indenture Default with respect to an
aircraft has occurred and is continuing. (Leased Aircraft Indentures, Section
5.02) The assignment by the Owner Trustee to the Loan Trustee of its rights
under the related lease excludes, among other things, the rights of the Owner
Trustee in its individual and trust capacities and of the Owner Participant
relating to the indemnification by us for certain matters, proceeds of public
liability insurance in respect of the aircraft payable as a result of insurance
claims made, or losses suffered, by the Owner Trustee or the Loan Trustee in
their respective individual capacities or by the Owner Participant, proceeds of
insurance maintained with respect to the aircraft by the Owner Participant
(whether directly or through the Owner Trustee) or the Owner Trustee in its
individual capacity and permitted under the lease and certain reimbursement
payments made by us to the Owner Trustee and the Owner Participant. (Leased
Aircraft Indentures, Granting Clause)

   The secured promissory notes will not be cross-collateralized. This means
that the secured promissory notes issued in respect of any one aircraft will
not be secured by any of the other aircraft, replacement aircraft (as described
in "--The Leases--Events of Loss") or the leases related to such other
aircraft.

                                      S-76
<PAGE>

   There will not be any cross-default provisions in the Indentures or leases.
This means that events resulting in an event of default under any particular
Indenture or lease may or may not result in an event of default occurring under
any other Indenture or lease. If the secured promissory notes issued with
respect to one or more aircraft are in default and the secured promissory notes
issued with respect to the remaining aircraft are not in default, no remedies
will be exercisable under the Indentures with respect to such remaining
aircraft.

   The secured promissory notes issued under each Leased Aircraft Indenture
will not be our obligations and we will not guarantee payment of or principal
of, or interest on, such secured promissory notes. Payments or advances made
under a lease and the related Aircraft Operative Agreements will always be
sufficient to make scheduled payments of principal of, and interest on, the
secured promissory notes issued to finance the aircraft subject to such lease.
See "Description of the Secured Promissory Notes--General."

Loan to Value Ratios of Secured Promissory Notes

   The following tables set forth illustrative loan to aircraft value ratios
for the secured promissory notes issued in respect of aircraft as of February
5, 2001 and each August 5 Regular Distribution Date thereafter, assuming that
the secured promissory notes in the maximum principal amount are issued in
respect of each such aircraft. We used this example to prepare the Assumed
Amortization Schedule, although the amortization schedule for the secured
promissory notes issued with respect to an aircraft may vary from such assumed
schedule so long as it complies with the Mandatory Economic Terms. This means
that the schedule set forth below may not be applicable in the case of any
particular aircraft. See "Description of the Certificates--Pool Factors." The
LTV was obtained by dividing (a) the outstanding balance (assuming no payment
default) of such secured promissory notes determined immediately after giving
effect to the payments scheduled to be made on each such Regular Distribution
Date by (b) the assumed value (the "Assumed Aircraft Value") of the aircraft
securing such secured promissory notes.

                                      S-77
<PAGE>

   The following tables are based on the Depreciation Assumption. Other rates
or methods of depreciation would result in materially different loan to
aircraft value ratios, and no assurance can be given (a) that the depreciation
rates and method assumed for the purposes of the tables are the ones most
likely to occur or (b) as to the actual future value of any aircraft. The
tables should not be considered a forecast or prediction of expected or likely
loan to aircraft value ratios, but only a mathematical calculation based on one
set of assumptions.

Limitation of Liability for Leased Aircraft Notes

   The secured promissory notes issued with respect to the leased aircraft will
not be our direct obligations nor will they be guaranteed by us, by any Owner
Participant or by the Loan Trustees or the Owner Trustees in their individual
capacities. None of the Owner Trustees, the Owner Participants or the Loan
Trustees, or any of their affiliates will be personally liable to any holder of
a secured promissory note or, in the case of the Owner Trustees and the Owner
Participants, to the Loan Trustees for any amounts payable under the secured
promissory notes or, except as provided in each Leased Aircraft Indenture, for
any liability under such Leased Aircraft Indenture.

   Generally, all payments of principal of, premium, if any, and interest on
the secured promissory notes issued with respect to any leased aircraft (other
than payments made in connection with an optional redemption or purchase of
secured promissory notes issued with respect to a leased aircraft by the
related Owner Trustee or the related Owner Participant) will be made only from
the assets subject to the lien of the Indenture with respect to such leased
aircraft or the income and proceeds received by the related Loan Trustee
(including rent payable and other amounts provided by us under the lease and
related documents with respect to such leased aircraft). In some cases, an
Owner Participant may be required to make payments to an Owner Trustee that are
to be used by the Owner Trustee to pay principal of, and interest on, the
secured promissory notes. If an Owner Participant is required to make payments
to be used by an Owner Trustee to pay principal of, and interest on, the
secured promissory notes and the Owner Participant fails to make the payment,
we will be required to provide the Owner Trustee with funds sufficient to make
the payment, except in the case of a voluntary termination of the lease where
the Owner Participant has elected to retain the Aircraft.

   Except as otherwise provided in the Leased Aircraft Indentures, no Owner
Trustee or Loan Trustee, in its individual capacity, will be answerable or
accountable under the Leased Aircraft Indentures or under the Leased Aircraft
Notes under any circumstances except, among other things, for its own willful
misconduct or gross negligence. None of the Owner Participants will have any
duty or responsibility under any of the Leased Aircraft Indentures or the
Leased Aircraft Notes to the Loan Trustees or to any holder of any secured
promissory note.

Liability For Owned Aircraft Notes

   The secured promissory notes issued with respect to any owned aircraft will
be our direct obligations.

   Except as otherwise provided in the Owned Aircraft Indentures, no Loan
Trustee, in its individual capacity, will be answerable or accountable under
the Owned Aircraft Indentures or any secured promissory notes issued with
respect to an owned aircraft under any circumstances except, among other
things, for its own willful misconduct or gross negligence.

Indenture Defaults, Notice and Waiver

 Indenture Defaults under each Indenture include:

  .  in the case of a Leased Aircraft Indenture, the occurrence of any Lease
     Event of Default under the related lease (other than the failure to make
     certain indemnity payments and other payments to the related Owner
     Trustee or Owner Participant unless a notice is given by such Owner
     Trustee to the Loan Trustee that such failure will constitute a Lease
     Event of Default);

  .  the failure by the related Owner Trustee (other than as a result of a
     Lease Default or Lease Event of Default) in the case of a Leased
     Aircraft Indenture, or us, in the case of an Owned Aircraft Indenture,
     to pay any interest or principal or premium, if any, when due, under
     such Indenture or under any secured promissory note issued under such
     Indenture that continues for more than 10 Business Days, in the case of
     principal, interest or Make-Whole Premium, and, in all other cases, 10
     Business Days

                                      S-79
<PAGE>

     after we (or, in the case of the Leased Aircraft Indenture, the relevant
     Owner Trustee and Owner Participant) receive written demand from the
     related Loan Trustee or holder of a secured promissory note;

  .  the failure by the related Owner Participant or the related Owner
     Trustee (in its individual capacity), in the case of a Leased Aircraft
     Indenture, or us, in the case of an Owned Aircraft Indenture, to
     discharge certain liens that continue after notice and specified cure
     periods;

  .  any representation or warranty made by the related Owner Trustee or
     Owner Participant in a Leased Aircraft Indenture, the related
     Participation Agreement, or certain related documents furnished to the
     Loan Trustee or any holder of a secured promissory note being false or
     incorrect when made in any material respect that continues to be
     material and adverse to the interests of the Loan Trustee or Note
     Holders and remains unremedied after notice and specified cure periods;

  .  any representation or warranty made by us in an Owned Aircraft
     Indenture, the related Participation Agreement, or certain related
     documents furnished to the Loan Trustee or any holder of a secured
     promissory note being false or incorrect when made in any material
     respect that continues to be material and adverse to the interests of
     the Loan Trustee or Note Holders and remains unremedied after notice and
     specified cure periods;

  .  failure by the related Owner Trustee or Owner Participant (in the case
     of leased aircraft) or us (in the case of owned aircraft) to perform or
     observe in any material respect any covenant or obligation for the
     benefit of the Loan Trustee or holders of secured promissory notes under
     such Indenture or certain related documents that continues after notice
     and specified cure periods;

  .  the registration of the related aircraft ceasing to be effective as a
     result of the Owner Participant (in the case of a leased aircraft) or us
     (in the case of an owned aircraft) not being a citizen of the United
     States, as defined in Title 49 of the United States Code relating to
     aviation (subject to a cure period);

  .  the occurrence of certain events of bankruptcy, reorganization or
     insolvency of the related Owner Trustee (not in its individual capacity)
     or Owner Participant (in the case of a leased aircraft) or us (in the
     case of the owned aircraft); or

  .  in the case of the Owned Aircraft Indenture, failure by us to carry and
     maintain insurance in accordance with the terms of such Indenture with
     respect to the aircraft. (Indentures, Section 4.02)

   There will not be any cross-default provisions in the Indentures or in the
leases. This means that events resulting in an Indenture Default under any
particular Indenture may or may not result in an Indenture Default occurring
under any other Indenture, and a Lease Event of Default under any particular
lease may or may not result in a Lease Event of Default under any other lease.

   If we fail to make any semiannual basic rental payment due under any lease,
within a specified period after such failure the applicable Owner Trustee or
Owner Participant may furnish to the Loan Trustee the amount due on the secured
promissory notes issued with respect to the related leased aircraft, together
with any interest thereon on account of such delayed payment. In that case, the
Loan Trustee and the holders of outstanding secured promissory notes issued
under such Indenture may not exercise any remedies otherwise available under
such Indenture or such lease as the result of such failure to make such rental
payment, unless such Owner Trustee or Owner Participant has previously cured
each of the three immediately preceding semiannual basic rental payment
defaults or the Owner Trustee has cured an aggregate of six previous semiannual
basic rental payment defaults. The applicable Owner Trustee also may cure any
other default by us in the performance of its obligations under any lease that
can be cured by the payment of money. (Leased Aircraft Indentures, Section
4.03)

   The holders of a majority in aggregate unpaid principal amount of the
secured promissory notes issued under an Indenture, by notice to the Loan
Trustee, may on behalf of all the holders of secured promissory notes issued
under such Indenture waive any existing default and its consequences under such
Indenture, except a

                                      S-80
<PAGE>

default in the payment of the principal of, or premium or interest on any such
secured promissory notes or a default in respect of any covenant or provision
of such Indenture that cannot be modified or amended without the consent of
each holder of secured promissory notes. In the case of Leased Aircraft
Indentures, the ability to waive existing defaults may depend on actions of the
applicable Owner Participant. (Indentures, Section 4.08)

Remedies

   Each Indenture provides that if an Indenture Default occurs and is
continuing, the related Loan Trustee may, and upon receipt of written demand
from the holders of a majority in principal amount of the secured promissory
notes outstanding under such Indenture will, subject to the applicable Owner
Participant's or Owner Trustee's right to cure in the case of Leased Aircraft
Indentures, declare the principal of all such secured promissory notes issued
under such Indenture immediately due and payable, together with all accrued but
unpaid interest thereon (without the Make-Whole Premium). The holders of a
majority in principal amount of secured promissory notes outstanding under such
Indenture may rescind any such declaration at any time before the judgment or
decree for the payment of the money so due is entered if (a) there has been
paid to the related Loan Trustee an amount sufficient to pay all principal and
interest on any such secured promissory notes, to the extent such amounts have
become due otherwise than by such declaration of acceleration and (b) all other
Indenture Defaults and events which with the giving of notice or lapse of time
or both would become Indenture Defaults under such Indenture with respect to
any agreement contained in such Indenture have been cured. (Indentures, Section
4.04(b))

   Each Indenture provides that if an Indenture Default under such Indenture
has occurred and is continuing, the related Loan Trustee may exercise certain
rights or remedies available to it under such Indenture or under applicable
law, including (if, in the case of a leased aircraft, the corresponding lease
has been declared in default) one or more of the remedies under such Indenture
or such lease with respect to the aircraft subject to such lease. If a Lease
Event of Default has occurred and is continuing under the corresponding lease
in the case of Leased Aircraft Indentures, the related Loan Trustee's right to
exercise remedies under such Indenture is subject, with certain exceptions, to
its having accelerated the maturity of the secured promissory notes and
proceeded to exercise one or more of the remedies under the lease to terminate
the lease (in the event that it is not commercially reasonable to take
possession of the aircraft) or take possession of and/or sell the aircraft;
provided that the requirement to exercise such remedies under such lease does
not apply in circumstances where such exercise has been involuntarily stayed or
prohibited by applicable law or court order for a continuous period (a
"Continuous Stay Period") in excess of 60 days subsequent to an entry for an
order for relief pursuant to Section 1110(a)(2)(A) of the Bankruptcy Code (the
"Section 1110 Period"); provided, however, that the requirement to exercise one
or more of such remedies under such lease shall nonetheless be applicable
during a Continuous Stay Period subsequent to the expiration of the Section
1110 Period to the extent that the continuation of such Continuous Stay Period
subsequent to the expiration of the Section 1110 Period (A) results from an
agreement by the trustee or the debtor-in-possession in such proceeding during
the Section 1110 Period with the approval of the relevant court to perform such
lease in accordance with Section 1110(a)(2)(A) of the U.S. Bankruptcy Code and
continues to perform as required by Section 1110(a)(2) of the U.S. Bankruptcy
Code and cures any default (other than a default of a kind specified in Section
365(b)(2) of the U.S. Bankruptcy Code) within the applicable time period
specified in Section 1110(a)(2)(B) of the U.S. Bankruptcy Code or (B) is an
extension of the Section 1110 Period with the consent of such Loan Trustee
pursuant to Section 1110(b) of the U.S. Bankruptcy Code or (C) is the
consequence of such Loan Trustee's own failure to give any requisite notice or
demand to any person. See "--The Leases--Events of Default under the Leases."
Such remedies may be exercised by the related Loan Trustee to the exclusion of
the related Owner Trustee, subject to certain conditions specified in such
Indenture, and us, subject to the terms of such lease. Any aircraft sold in the
exercise of such remedies will be free and clear of any rights of those
parties, including, if a Lease Event of Default has occurred and is continuing,
our rights under the lease with respect to such aircraft. No exercise of any
remedies by the related Loan Trustee may affect our rights under any lease
unless a Lease Event of Default has occurred and is continuing under such
lease. The Owned Aircraft Indentures will not contain such limitations on the
Loan Trustee's ability to exercise remedies upon an Indenture Default under an
Owned Aircraft Indenture. (Indentures, Section 4.04; Leases, Section 15)

                                      S-81
<PAGE>

   If we are the debtor in a bankruptcy proceeding under the U.S. Bankruptcy
Code, all of the rights of the Owner Trustee as lessor under a particular lease
will be exercised by the Owner Trustee in accordance with the terms thereof
unless (a) during the Section 1110 Period we or the trustee in such proceeding
do not agree to perform our obligations under such lease, (b) at any time after
agreeing to perform such obligations, we or such trustee cease to perform such
obligations, (c) the related Loan Trustee takes action, or notifies the Owner
Trustee that such Loan Trustee intends to take action, to foreclose the lien of
the related Leased Aircraft Indenture or otherwise commence the exercise of any
significant remedy in accordance with the Leased Aircraft Indenture or (d) the
secured promissory notes issued pursuant to such Indenture have been declared
due and payable by the related Loan Trustee. The Owner Trustee's exercise of
such rights will be subject to certain limitations and, in no event may the
Owner Trustee reduce the amount or change the time of any payment in respect of
the secured promissory notes or adversely affect the validity or enforceability
of the lien under the Leased Aircraft Indenture by depriving the holder of the
secured promissory notes of the benefits thereof. (Leased Aircraft Indentures,
Section 9.01(b))

   There will not be any cross-default provisions in the Indentures. This means
that if the secured promissory notes issued in respect of one aircraft are in
default, the secured promissory notes issued in respect of the other aircraft
might not be in default, and, if not, no remedies will be exercisable under the
applicable Indentures with respect to such other aircraft.

   Section 1110 of the U.S. Bankruptcy Code provides that the right of a
secured party with a security interest in "equipment" (as defined in Section
1110 of the U.S. Bankruptcy Code), or of a lessor or conditional vendor of such
equipment, to take possession of such equipment in compliance with the
provisions of a security agreement, lease, or conditional sale contract, and to
enforce any of its other rights or remedies under such security agreement,
lease, or conditional sale contract, to sell, lease or otherwise retain or
dispose of such equipment, is not limited or otherwise affected after 60 days
after the order for relief under Chapter 11 of the U.S. Bankruptcy Code by any
other provision of the U.S. Bankruptcy Code or by any power of the bankruptcy
court.

   Section 1110 of the U.S. Bankruptcy Code provides that the right to take
possession and to enforce other rights and remedies to sell, lease or otherwise
dispose of an aircraft shall be subject to the automatic stay of Section 362 of
the bankruptcy code if (A) before the date that is 60 days after the date of
the order for relief under Chapter 11 of the U.S. Bankruptcy code, the trustee,
subject to the approval of the court, agrees to perform all obligations of the
debtor under such security agreement, lease or conditional sale contract and
(B) any default (other than a default that is a breach of a provision relating
to the financial condition, bankruptcy, insolvency or reorganization of the
debtor) under such security agreement, lease or conditional sale contract (x)
is cured before the date that is 60 days from the date of such order in the
case of a default that occurs before the date of the order of relief, (y) is
cured before the later of the date that is 30 days after the date of such
default or the date that is 60 days from the date of the order for relief in
the case of a default that occurs after the date of the order for relief and
before the date that is 60 days from the date of such order for relief, or (z)
is cured in compliance with the terms of the security agreement, lease or
conditional sale agreement in the case of a default that occurs on or after the
expiration of 60 days from the date of the order of relief. "Equipment" is
defined in Section 1110 of the U.S. Bankruptcy Code, in part, as "an aircraft,
aircraft engine, propeller, appliance, or spare part (as defined in section
40102 of title 49) that is subject to a security interest granted by, leased
to, or conditionally sold to a debtor that at the time such transaction is
entered into holds an air carrier operating certificate issued pursuant to
chapter 447 of title 49 for aircraft capable of carrying 10 or more individuals
or 6,000 pounds or more of cargo."

   Skadden, Arps, Slate, Meagher & Flom (Illinois), our special counsel, has
advised the Loan Trustees that, if we become a debtor under Chapter 11 of the
U.S. Bankruptcy Code, the Loan Trustee would be entitled to the benefits of
Section 1110 of the U.S. Bankruptcy Code with respect to the airframe and
engines comprising the related aircraft, but may not be entitled to such
benefits with respect to any replacement of an aircraft after an Event of Loss
in the future. The replacement of any aircraft is conditioned upon the
contemporaneous delivery of an opinion of counsel to the effect that the
related Loan Trustee's entitlement to benefits of Section 1110 of the U.S.
Bankruptcy Code would not be diminished as a result of such replacement. This
opinion is

                                      S-82
<PAGE>

subject to certain qualifications and assumptions, including the assumptions
that we, at the time of purchase of the secured promissory notes, hold an air
carrier operating certificate pursuant to chapter 447 of title 49 of the U.S.
Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or
more of cargo. See "--The Leases--Events of Loss." The opinion of Skadden,
Arps, Slate, Meagher & Flom (Illinois) does not address the availability of
Section 1110 with respect to the bankruptcy proceedings of any possible
sublessee of an aircraft, or to any possible lessee of an owned aircraft if it
is leased by us. For a description of certain limitations on the Loan Trustee's
exercise of rights contained in the Indenture, see "--Indenture Defaults,
Notice and Waiver."

   If a bankruptcy, insolvency, receivership or like proceedings is commenced
involving an Owner Participant, it is possible that, notwithstanding that the
applicable leased aircraft is owned by the related Owner Trustee in trust, such
leased aircraft and the related lease and secured promissory notes might become
part of such proceeding. In such event, payments under such lease or on such
secured promissory notes may be interrupted and the ability of the related Loan
Trustee to exercise its remedies under the related Leased Aircraft Indenture
might be restricted, although such Loan Trustee would retain its status as a
secured creditor in respect of the related lease and the related leased
aircraft.

Modification of Indentures and Leases

   Without the consent of holders of a majority in principal amount of the
secured promissory notes outstanding under any Indenture, the provisions of
such Indenture and any related lease, Participation Agreement or Leased
Aircraft Trust Agreement may not be amended or modified, except to the extent
indicated below.

   Subject to certain limitations, certain provisions of any Leased Aircraft
Indenture, and of the related lease, Participation Agreement, and Leased
Aircraft Trust Agreement, may be amended or modified by the parties to those
agreements without the consent of any holders of the secured promissory notes
outstanding under such Indenture. In the case of each lease, such provisions
include, among others, provisions relating to (a) the return to the related
Owner Trustee of the related leased aircraft under the terms of such lease
(except to the extent that such amendment would affect the rights or exercise
of remedies under the lease) and (b) the renewal of such lease and our option
pursuant to the terms of such lease to terminate the lease or to purchase the
related leased aircraft so long as the same would not adversely affect the Note
Holders. (Leased Aircraft Indentures, Section 9.01(a)) In addition, any
Indenture may be amended without the consent of the holders of secured
promissory notes issued under such Indenture to, among other things, cure any
defect or inconsistency in such Indenture or such secured promissory notes,
provided that such change does not adversely affect the interests of any such
holder. (Leased Aircraft Indentures, Section 9.01(c); Owned Aircraft
Indentures, Section 10.01(c))

   Without the consent of the Liquidity Provider, Policy Provider and the
holder of each secured promissory note outstanding under any Indenture affected
thereby, no amendment or modification of such Indenture may among other things
(a) reduce the principal amount of, or premium, if any, or interest payable on,
any secured promissory notes issued under such Indenture or change the date on
which any principal, premium, if any, or interest is due and payable, (b)
permit the creation of any security interest with respect to the property
subject to the lien of such Indenture, except as permitted by such Indenture,
or deprive any holder of a secured promissory note issued under such Indenture
of the benefit of the lien of such Indenture upon the property subject to such
Indenture or (c) reduce the percentage in principal amount of outstanding
secured promissory notes issued under such Indenture necessary to modify or
amend any provision of such Indenture or to waive compliance with such
Indenture. (Leased Aircraft Indentures, Section 9.01(b); Owned Aircraft
Indenture, Section 10.01(b))

Indemnification

   We are required to indemnify each Loan Trustee, each Owner Participant, each
Owner Trustee, the Liquidity Provider, the Policy Provider, the Subordination
Agent, the Escrow Agent and the pass through

                                      S-83
<PAGE>

trustee, but not the holders of certificates (unless otherwise expressly
agreed by us), for certain losses, claims and other matters. We are required
under certain circumstances to indemnify each Owner Participant against the
loss of depreciation deductions and certain other benefits allowable for
certain income tax purposes with respect to the related leased aircraft.

The Leases and the Owned Aircraft Indentures

   We will lease each leased aircraft from an Owner Trustee under a lease. We
will own each owned aircraft.

 Lease Term and Lease Payments

   We will lease each leased aircraft from an Owner Trustee for a term
commencing on the closing of a leveraged lease financing and expiring on a
date not earlier than the latest maturity date of the relevant secured
promissory notes issued in such leveraged lease transaction, unless terminated
prior to the originally scheduled expiration date as permitted by such lease.
We will make semiannual payments of basic rent under each lease on each rent
payment date (or, if such day is not a Business Day, on the next Business
Day).

   The Owner Trustee will assign all payments of basic rent and certain other
payments that we are required to pay or advance under the lease or related
documents to the related Loan Trustee. The Loan Trustee will, on behalf of the
Owner Trustee, apply the funds assigned to it under the related Indenture to
pay scheduled principal of, premium, if any, and interest due from such Owner
Trustee on the secured promissory notes issued under such Indenture. The
balance of any basic rent or other assigned amount under each lease and
related Aircraft Operative Agreements, after payment of amounts due on the
secured promissory notes issued under such Indenture, will be paid over to the
applicable Owner Trustee. In certain cases, the basic rent and other payments
under a lease may be adjusted, but each lease will provide that under no
circumstances will amounts that we are required to pay or advance under the
lease and related documents be less than the scheduled payments on the related
secured promissory notes. In some cases, an Owner Participant may be required
to make payments to an Owner Trustee that are to be used by the Owner Trustee
to pay principal of, and interest on, the secured promissory notes. If an
Owner Participant is required to make payments to be used by an Owner Trustee
to pay principal of, and interest on, the secured promissory notes and the
Owner Participant fails to make the payment, we will be required to provide
the Owner Trustee with funds sufficient to make the payment. Our obligations
to pay rent and to cause other payments to be made under each lease and under
the Aircraft Operative Agreements will be general unsecured obligations.

 Owned Aircraft Payments

   Semiannual payments of interest on the secured promissory notes issued by
us under an Owned Aircraft Indenture are payable on February 5 and August 5 of
each year, commencing on the first such date after issuance thereof. Payments
of principal of the secured promissory notes issued by us under an Owned
Aircraft Indenture are payable on February 5 and August 5 in certain years.

 Net Lease; Maintenance

   Under the terms of each lease, our obligations in respect of each leased
aircraft will be those of a lessee under a "net lease." This means that we
will be obligated under each lease, among other things, to keep each aircraft
subject to such lease duly registered and insured, to pay all costs of
operating the aircraft and to maintain, service, repair and overhaul such
aircraft so as to keep it in as good an operating condition as when delivered
to us, ordinary wear and tear excepted, and in such condition as required to
maintain the applicable airworthiness certificate for the aircraft in good
standing at all times (other than during temporary periods of storage, or
during certain periods of permitted maintenance or modification or when all
similar Airbus aircraft have been grounded by the FAA). (Leases, Section
7(a)(1))

                                     S-84
<PAGE>

 Possession, Sublease and Transfer

   We may operate an aircraft, or, subject to certain restrictions, we may
permit certain other persons to operate an aircraft. Normal interchange,
pooling and similar agreements customary in the commercial airline industry
with respect to any airframe or engine are permitted. We are also permitted to
enter into subleases (or, in the case of owned aircraft, leases) with United
States entities and foreign entities that have their principal executive office
in specified countries. (Leases, Section 7(b)(x), Owned Aircraft Indentures,
Section 7.02(b)(x)). All subleases will be subject and subordinate to the
related lease. All leases of owned aircraft will be subject and subordinate to
the lien of the related Owned Aircraft Indenture. It is uncertain to what
extent the relevant Loan Trustee's security interest would be recognized if an
aircraft is registered or located in a jurisdiction not a party to the
Convention on the International Recognition of Rights in Aircraft (Geneva 1948)
(the "Convention"). In the case of an Indenture Default, the ability of the
related Loan Trustee to realize upon its security interest in an aircraft could
be adversely affected as a legal or practical matter if such aircraft were
registered or located outside of the United States.

 Registration

   We are required to keep each aircraft duly registered under the
Transportation Code with the FAA except (in the case of a leased aircraft) if
the relevant Owner Trustee or the relevant Owner Participant fails to meet the
applicable citizenship requirements. We are also required to record each lease
(in the case of a leased aircraft) and Indenture and certain other documents
under the Transportation Code. (Leases, Section 7(a); Owned Aircraft
Indentures, Section 7.02) Each Indenture will be effective to create a valid
security interest in the aircraft that is subject to such Indenture. When the
Indenture and other appropriate documents are filed with the FAA and in
accordance with the Transportation Code and Uniform Commercial Code financing
statements are filed in all appropriate jurisdictions, the Loan Trustee will
have a first-priority, perfected security interest in such aircraft whenever it
is located in the United States or any of its territories and possessions. The
Convention provides that such security interest will also be recognized, with
certain limited exceptions, in those jurisdictions that have ratified or adhere
to the Convention.

   So long as no Lease Event of Default exists, we have the right to register
the aircraft subject to such lease in a country other than the United States at
our own expense, subject to certain conditions set forth in the related
Participation Agreement. These conditions include a requirement that the lien
of the applicable Indenture will continue as a first priority security interest
in the applicable aircraft. (Leases, Section 7(a)(1); Participation Agreements,
Section 7(d)). The Owned Aircraft Indentures and related documents contain
comparable provisions with respect to registration of the owned aircraft.

 Liens

   We are required to maintain each aircraft free of any liens, other than the
rights of the parties under the Aircraft Operative Agreements and other than
certain limited liens permitted under such Aircraft Operative Agreements. Such
permitted liens include, but are not limited to:

  (a) liens for taxes either not yet due or being contested in good faith by
      appropriate proceedings;

  (b) materialmen's, mechanics' and other similar liens arising in the
      ordinary course of business and securing obligations that either are
      not yet delinquent for more than sixty (60) days (or such shorter
      period as may be specified in the applicable lease) or are being
      contested in good faith by appropriate proceedings;

  (c) judgment liens so long as such judgment is discharged or vacated within
      sixty (60) days or the execution of such judgment is stayed pending
      appeal or discharged, vacated or reversed within sixty (60) days after
      expiration of such stay; and

  (d) any other lien as to which we have provided a bond or other security
      adequate in the reasonable opinion of the Owner Trustee;

provided that in the case of each of the liens described in the foregoing
clauses (a) and (b) such liens and proceedings do not involve any material risk
of the sale, forfeiture or loss of such aircraft or any interest in such
aircraft. (Leases, Section 6; Owned Aircraft Indentures, Section 7.01)

                                      S-85
<PAGE>

 Replacement of Parts; Alterations

   We are obligated to replace all aircraft parts at our expense that may from
time to time be incorporated or installed in or attached to any aircraft and
that may become lost, damaged beyond repair, worn out, destroyed, stolen,
seized, confiscated or permanently rendered unfit for use. We or any permitted
sublessee (or, in the case of an owned aircraft, any permitted lessee) have the
right, at our own expense, to add further parts and accessories and make such
alterations, modifications and additions with respect to each aircraft as we
deem desirable in the proper conduct of our business and to remove parts which
we deem to be obsolete or no longer suitable or appropriate for use, so long as
such alteration, modification, addition or removal does not materially diminish
the value, utility or remaining useful life of the related aircraft. (Leases,
Sections 8(a) and 8(c); Owned Aircraft Indenture, Sections 7.03(a) and 7.03(c))

 Insurance

   We are required to maintain, at our expense (or at the expense of a
permitted lessee, in the case of the owned aircraft, or a permitted sublessee
in the case of a leased aircraft), all-risk aircraft hull insurance covering
each aircraft, at all times in an amount (taking into account any permitted
self-insurance) not less than the termination value (or comparable amount) for
the aircraft. However, after giving effect to self-insurance permitted as
described below, the amount payable under such insurance may be less than such
amounts payable with respect to the secured promissory notes. (Leases, Section
11; Owned Aircraft Indentures, Section 7.04)

   In addition, we are obligated to maintain (or cause to be maintained)
comprehensive airline liability insurance at our expense, including, without
limitation, passenger liability, bodily injury and property damage liability,
cargo liability and contractual liability insurance with respect to each
aircraft. Such liability insurance must be underwritten by insurers of
nationally or internationally recognized responsibility. The amount of such
liability insurance coverage per occurrence may not be less than the amount of
comprehensive airline liability insurance from time to time applicable to
aircraft of the same type that we own, lease or operate that operate on similar
routes as such aircraft.

   We are also required to maintain war-risk, hijacking or allied perils
insurance if we (or any permitted lessee or sublessee) operate any aircraft,
airframe or engine in any area of recognized hostilities or if we (or any
permitted lessee or sublessee) maintain such insurance with respect to other
aircraft operated on the same international routes or areas on or in which the
aircraft is operated and it is customary in the airline industry to maintain
such insurance for aircraft operated on the same international routes or areas
on or in which the aircraft is operated. (Leases, Section 11; Owned Aircraft
Indentures, Section 7.04)

   We may self-insure under a program applicable to all aircraft in our fleet,
but the amount of such self-insurance in the aggregate may not exceed 50% of
the highest replacement value of any single aircraft in our fleet or 1.5% of
the average aggregate insurable value (during the preceding policy year) of all
aircraft on which we carry insurance, whichever is less, and for owned aircraft
and certain leases, unless an insurance broker of national standing will
certify that the standard among all other major United States airlines is a
higher level of self-insurance, in which case, we may self-insure the aircraft
to such higher level. In addition, we may self-insure to the extent of any
applicable deductible per aircraft that does not exceed industry standards for
major United States airlines. (Leases, Section 11; Owned Aircraft Indentures,
Section 7.04)

   In respect of each aircraft, we are required to name as additional insured
parties the relevant Loan Trustee and holders of the secured promissory notes
and (in the case of a leased aircraft) the relevant Owner Participant and Owner
Trustee, in its individual capacity and as owner of such aircraft, and the
Liquidity Provider and the Policy Provider under all liability, hull and
property and war risk, hijacking and allied perils insurance policies required
with respect to such aircraft. In addition, the insurance policies will be
required to provide that, in respect of the interests of such additional
insured persons, the insurance will not be invalidated or impaired by any of
our acts or omissions or by any act or omission of any permitted sublessees, or
any other person. (Leases, Section 11; Owned Aircraft Indentures, Section 7.04)

                                      S-86
<PAGE>

 Lease Termination

   We may terminate any lease on any Rent Payment Date (or if the applicable
Owner Participant agrees on scheduled monthly termination dates) occurring
after the end of the calendar year in which the seventh (7th) anniversary of
the occurrence of the lease commencement date, if we make a good faith
determination that the aircraft subject to such lease is obsolete or surplus to
our needs. We are required to give notice of our intention to exercise our
right of termination described in this paragraph at least one hundred twenty
(120) days prior to the proposed termination date, which notice may be
withdrawn up to fifteen (15) days prior to such proposed termination date;
provided that we may give only two (2) such termination notices. In such a
situation, unless the Owner Trustee elects to retain title to such aircraft, we
are required to use commercially reasonable efforts to sell such aircraft as an
agent for such Owner Trustee, and the Owner Trustee will sell such aircraft on
the date of termination to the highest cash bidder. If such sale occurs, the
secured promissory notes related thereto are required to be prepaid. If the net
proceeds to be received from such sale are less than the termination value (or
comparable termination amount) for such aircraft (which will be set forth in a
schedule to each lease), we are required to pay to the applicable Owner Trustee
an amount equal to the excess, if any, of the applicable termination value (or
comparable termination amount) for such aircraft over such net proceeds.

   We may have other early termination provisions under the leases which would
allow us to either sell the aircraft as agent for the applicable Owner Trustee
or to purchase the aircraft. If we elect to purchase the aircraft, either (a)
the secured promissory notes related thereto will be prepaid or (b) subject to
receipt of the tax opinion and Section 1110 opinion described under "--Renewal
and Purchase Options," we will assume such secured promissory notes on a full
recourse basis. Upon payment of the termination value (or comparable amount)
or, in the case of a purchase by us, the payment of the applicable purchase
price, and an amount equal to the Make-Whole Premium, if any, payable on such
date of payment, together with certain additional amounts, the lien of the
relevant Indenture will be released, the relevant lease will terminate, and our
obligation after the date of such payments to make scheduled rent payments
under such lease will cease. (Leases, Sections 9 and 20; Leased Aircraft
Indentures, Section 2.10(b))

   Except in the case of a termination option that allows us to purchase the
aircraft, the Owner Trustee has the option to retain title to the aircraft if
we have given a notice of termination under the lease. In such event, such
Owner Trustee will pay to the applicable Loan Trustee an amount sufficient to
prepay the outstanding secured promissory notes issued with respect to such
aircraft (including accrued interest) and the Loan Trustee will be paid the
Make-Whole Premium, in which case the lien of the relevant Indenture will be
released, the relevant lease will terminate and our obligation after the date
of such payments to make scheduled rent payments under such lease will cease.
(Leases, Section 9; Leased Aircraft Indentures, Section 2.10(b))

 Events of Loss

   If an Event of Loss occurs with respect to the airframe or the airframe and
engines of an aircraft, we must elect within sixty (60) days after such
occurrence either to make payment with respect to such Event of Loss or to
replace such airframe and any such engines. Not later than the earlier of (a)
the first Business Day following the 120th day (or such earlier day as may be
specified in the applicable lease) following the date of occurrence of such
Event of Loss and (b) an earlier Business Day irrevocably specified fifteen
(15) days in advance by notice from us to the Owner Trustee (in the case of a
leased aircraft) and the Loan Trustee, we must either (a) pay to the applicable
Owner Trustee the termination value (or comparable termination amount) of such
aircraft (or, in the case of an owned aircraft, pay to the applicable Loan
Trustee the outstanding principal amount of the secured promissory notes
relating to such aircraft plus accrued and unpaid interest thereon), together
with certain additional amounts, but, in any case, without any Make-Whole
Premium or (b) substitute an airframe (or airframe and one or more engines, as
the case may be) for the airframe, or airframe and engine(s), that suffered
such Event of Loss. (Leases, Section 10(a); Leased Aircraft Indentures, Section
2.10; Owned Aircraft Indentures, Section 5.06)

   If we elect to replace an airframe (or airframe and one or more engines, as
the case may be) that suffered such Event of Loss, we will, in the case of a
leased aircraft, convey to the related Owner Trustee title to an

                                      S-87
<PAGE>

airframe (or airframe and one or more engines, as the case may be) or, in the
case of an Owned Aircraft Indenture, subject such airframe (or airframe and one
or more engines) to the lien of the Owned Aircraft Indenture, and such
replacement airframe or airframe and engines must be the same model as the
airframe or airframe and engines to be replaced or an improved model, with a
value, utility and remaining useful life at least equal to the airframe or
airframe and engines to be replaced, assuming that such airframe and such
engines had been maintained in accordance with the related lease or Owned
Aircraft Indenture, as the case may be. We are also required to provide to the
relevant Loan Trustee and (in the case of a leased aircraft) the relevant Owner
Trustee and Owner Participant reasonably acceptable opinions of counsel to the
effect, among other things, that (a) certain specified documents have been duly
filed under the Transportation Code and (b) such Owner Trustee and Loan Trustee
will be entitled to receive the benefits of Section 1110 of the U.S. Bankruptcy
Code with respect to any such replacement airframe (unless, as a result of a
change in law or court interpretation, such benefits are not then available).
(Leases, Section 10(a); Owned Aircraft Indentures, Section 5.06)

   If we elect not to replace such airframe, or airframe and engine(s), then
upon payment of the outstanding principal amount of the secured promissory
notes issued with respect to such aircraft (in the case of an owned aircraft)
or the termination value (or comparable termination amount) for such aircraft
(in the case of a leased aircraft), together with all additional amounts then
due and unpaid with respect to such aircraft, which must be at least sufficient
to pay in full as of the date of payment thereof the aggregate unpaid principal
amount under such secured promissory notes together with accrued but unpaid
interest thereon and all other amounts due and owing in respect of such secured
promissory notes, the lien of the Indenture and (in the case of a leased
aircraft) the lease relating to such aircraft will terminate with respect to
such aircraft, our obligation thereafter to make the scheduled rent payments
(in the case of a leased aircraft) or interest and principal payments (in the
case of an owned aircraft) will cease and (in the case of a leased aircraft)
the related Owner Trustee will transfer all of its right, title and interest in
and to the related aircraft to us. The termination value (or comparable
termination amount) and other payments made under the leases by us will be
deposited with the applicable Loan Trustee. Amounts in excess of the amounts
due and owing under the secured promissory notes issued with respect to such
aircraft will be distributed by such Loan Trustee to the applicable Owner
Trustee or to us, as the case may be. (Leases, Section 10; Leased Aircraft
Indentures, Section 3.02; Owned Aircraft Indentures, Sections 3.02 and 5.06)

   If an Event of Loss occurs with respect to an engine alone, we will be
required to replace such engine within one hundred twenty (120) days after the
occurrence of such Event of Loss with another engine, free and clear of all
liens (other than certain permitted liens). Such replacement engine will be (a)
a CFM International Model 56-5 (or improved) type engine or (b) another CFM
engine or another manufacturer's engine suitable for use on the relevant
airframe and having a value and utility equal to or greater than a CFM
International Model 56-5 type engine. (Leases, Section 10(b); Owned Aircraft
Indentures, Section 5.06(b))

 Renewal and Purchase Options

   At the end of the term of each lease after final maturity of the related
secured promissory notes and subject to certain conditions, we have certain
options to renew such lease for additional limited periods. In addition, we
have the right at the end of the term of each lease to purchase the aircraft
subject to such lease for an amount to be calculated in accordance with the
terms of such lease. (Leases, Section 19)

   In addition, we may have the right to purchase an aircraft from the
applicable Owner Trustee prior to the expiration of the term of such lease. If
we purchase an aircraft from the applicable Owner Trustee prior to the end of
the term, we may assume, as our direct obligations, the secured promissory
notes issued with respect to such aircraft. We may only assume the secured
promissory notes if, among other things, we have provided opinions of counsel
to the effect that (a) holders of such secured promissory notes will not
recognize income, gain or loss for federal income tax purposes as a result of
such assumption and will be subject to taxation in the same amounts, and in the
same manner and at the same times as would have been the case if such
assumption had not occurred, (b) the Loan Trustee will be entitled to the
benefits of Section 1110 of the U.S. Bankruptcy Code with respect to the
airframe and engines comprising such aircraft, as long as, at the time of
purchase of

                                      S-88
<PAGE>

the secured promissory notes, we hold an air carrier operating certificate
issued pursuant to Chapter 447 of Title 49 of the Code for aircraft capable of
carrying 10 or more individuals or 6,000 pounds or more of cargo and (c) we
have received confirmation from each of the rating agencies that such
assumption would not result in the reduction in the rating of the certificates
or the withdrawal or suspension of such rating. (Leases, Section 19 and Section
20; Participation Agreements, Section 7(r); Indentures, Section 2.13)

 Events of Default under the Leases

   The following events (and certain other events as may be specified in the
applicable lease) constitute Lease Events of Default under each lease:

  .  Our failure to make any payment of basic rent within five (5) Business
     Days after the same has become due or termination value (or comparable
     termination amount) within ten (10) Business Days after receipt by us of
     written notice that the same is past due.

  .  Our failure to make a payment of supplemental rent (other than
     termination value (or comparable termination amount)) when the same has
     become due and for thirty (30) days (or such shorter period as may be
     specified in the applicable Lease) after we receive written demand for
     such payment (provided that failure to pay any amount that is excluded
     from the lien of the Indenture will not constitute an event of default
     unless notice is given by the Owner Participant).

  .  Our failure to carry and maintain insurance on and in respect of the
     aircraft, airframe and engines, in accordance with the provisions of
     such lease.

  .  Our failure to perform or observe in any material respect any other
     covenant or agreement to be performed or observed by us under such lease
     or the related Aircraft Operative Agreements (other than our related tax
     indemnity agreement with the Owner Participant), and such failure
     continuing unremedied for a period of thirty (30) days after written
     notice of such failure by the applicable Owner Trustee or Loan Trustee
     unless such failure is capable of being corrected and we are diligently
     proceeding to correct such failure, in which case there is no Lease
     Event of Default unless and until such failure continues unremedied for
     a period of three hundred sixty (360) days (or such shorter period as
     may be specified in the applicable Lease) after the receipt of such
     notice.

  .  Any representation or warranty made by us in such lease or the related
     Aircraft Operative Agreements (other than our related tax indemnity
     agreement with the Owner Participant) proves to have been untrue or
     inaccurate in any material respect at the time made, and the same
     remains uncured for more than thirty (30) days after receipt by us of
     written notice.

  .  The occurrence of certain voluntary events of our bankruptcy,
     reorganization or insolvency or the occurrence of involuntary events of
     bankruptcy, reorganization or insolvency which continues undismissed,
     unvacated or unstayed for a period of ninety (90) days. (Leases, Section
     14)

   Indenture Events of Default under the Owned Aircraft Indenture are discussed
above under "--Indenture Defaults, Notice and Waiver."

 Remedies Exercisable upon Events of Default under the Lease

   If a Lease Event of Default has occurred and is continuing, the applicable
Owner Trustee may (or, so long as the Indenture is in effect, the applicable
Loan Trustee may, subject to the terms of the Indenture) exercise one or more
of the remedies provided in such lease with respect to the related aircraft.
These remedies include the right to repossess and use or operate such aircraft,
to rescind or terminate such lease, to sell or re-lease such aircraft free and
clear of our rights, except as set forth in the lease, and retain the proceeds,
and to require us to pay, as liquidated damages any due and unpaid basic rent
plus an amount equal to, at such Owner Trustee's (or, subject to the terms of
the relevant Leased Aircraft Indenture, the Loan Trustee's) option, either (a)
the excess of the termination value (or comparable termination amount) over the
present value of the fair market rental value of such aircraft for the
remainder of the term of such lease or, (b) the excess of the termination value
(or

                                      S-89
<PAGE>

comparable termination amount) of such aircraft over the fair market sales
value of such aircraft or, if such aircraft has been sold, the net sales
proceeds from the sale of such aircraft. If the Loan Trustee has validly
terminated such lease, the Loan Trustee may not sell or lease or otherwise
afford the use of such aircraft, without the consent of the applicable Owner
Participant, to us or any of our affiliates. (Leased Aircraft Indentures,
Section 4.04)

 Transfer of Owner Participant Interests

   Subject to certain restrictions, each Owner Participant may transfer all or
any part of its interest in the related leased aircraft. (Basic Leased Aircraft
Participation Agreement, Section 7(k); Special Leased Aircraft Participation
Agreement, Section 7(j))

                            U.S. INCOME TAX MATTERS

General

   The following summary describes the material U.S. federal income tax
consequences to certificateholders of the purchase, ownership and disposition
of the certificates offered by this prospectus supplement and in the opinion of
Skadden, Arps, Slate, Meagher & Flom LLP, tax counsel to US Airways, is
accurate in all material respects with respect to the matters discussed in this
prospectus supplement. This summary restates and supplements the summary of
U.S. federal income tax consequences set forth in the prospectus. Except as
otherwise specified, the summary is addressed to the initial beneficial owners
of certificates that are citizens or residents of the United States,
corporations, partnerships or other entities created or organized in or under
the laws of the United States or any state therein, or estates, the income of
which is subject to U.S. federal income taxation regardless of its source, or
trusts if a court within the U.S. is able to exercise primary jurisdiction over
the administration of the trust and one or more U.S. persons have the authority
to control all substantial decisions of the trust that will hold the
certificates as capital assets. This summary does not address the tax treatment
of U.S. certificateholders that may be subject to special tax rules, for
example, banks or insurance companies, nor does it address the tax treatment of
U.S. certificateholders that do not acquire certificates at the initial
offering price as part of the initial offering. This summary is not a
comprehensive description of all of the tax considerations that may be relevant
to a decision to purchase certificates. It does not describe any tax
consequences arising under the laws of any state, locality or taxing
jurisdiction other than the United States.

   The summary is based on laws, regulations, rulings and decisions in effect
on the date of this prospectus supplement. Changes to existing law could have a
retroactive effect and could alter the tax consequences discussed below. No
rulings have been sought from the IRS with respect to the federal income tax
consequences, discussed below, and no assurances can be given that the IRS will
not take contrary positions. The pass through trust is not indemnified for any
federal income taxes that may be imposed upon it, and the imposition of those
taxes on the pass through trust could result in a reduction in the amounts
available for distribution to the certificateholders. Prospective investors
should consult their own tax advisors with respect to the federal, state, local
and foreign tax consequences to them of the purchase, ownership and disposition
of the certificates.

Tax Treatment of the Pass Through Trust and Certificateholders

   The pass through trust will not itself be subject to U.S. federal income
taxation. Each U.S. certificateholder will be required to report on its federal
income tax return its pro rata share of the entire income from the secured
promissory notes and any other property held in the pass through trust, in
accordance with the U.S. certificateholder's method of accounting. Accordingly,
each U.S. certificateholder's share of interest paid on the secured promissory
notes will be taxable as ordinary income, as it is paid or accrued, and a U.S.
certificateholder's share of any premium paid on redemption of a secured
promissory note will be treated as capital gain. If the proceeds from the sale
of certificates are invested with a depositary or held pursuant to an escrow
arrangement prior to the purchase of secured promissory notes by the pass
through trust, each U.S.

                                      S-90
<PAGE>

certificateholder's share of interest paid on the resulting deposits will be
taxable as ordinary income as it is paid or accrued in accordance with the
holder's method of accounting for U.S. federal income tax purposes. In
addition, the deposits may be subject to the original issue discount rules,
with the result that a U.S. certificateholder may be required to include any
original issue discount in income from a deposit using the accrual method of
accounting regardless of its normal method. Any amounts received by the pass
through trust under the liquidity facility or the insurance policy for unpaid
interest will be treated for U.S. federal income tax purposes as having the
same characteristics as the payments they replace.

   Each U.S. certificateholder will be entitled to deduct, consistent with its
method of accounting, its pro rata share of fees and expenses paid or incurred
by the pass through trust as provided in Section 162 or 212 of the Code.
Certain fees and expenses, including fees paid to the pass through trustee, the
provider of the liquidity facility and the provider of the insurance policy, if
applicable, will be paid by parties other than the certificateholders. These
fees and expenses could be treated as constructively received by the pass
through trust, in which event a U.S. certificateholder could be required to
include in income and entitled to deduct its pro rata share of the fees and
expenses. If a U.S. certificateholder is an individual, estate or trust, the
deduction for the certificateholder's share of fees or expenses will be allowed
only to the extent that all of the certificateholder's miscellaneous itemized
deductions, including the certificateholder's share of fees and expenses,
exceed 2% of the certificateholder's adjusted gross income. In addition, in the
case of U.S. certificateholders who are individuals, certain otherwise
allowable itemized deductions will be subject generally to additional
limitations on itemized deductions under applicable provisions of the Code.

Sale or Other Disposition of the Certificates

   Upon the sale, exchange or other disposition of a certificate, a U.S.
certificateholder generally will recognize capital gain or loss equal to the
difference between the amount realized on the sale or exchange (other than any
amount attributable to accrued but unpaid interest that the U.S.
certificateholder has not included in gross income previously, which will be
taxable as ordinary income) and the U.S. certificateholder's adjusted tax basis
in the secured promissory notes and other property held by the pass through
trust and any deposits. Any gain or loss will be long-term capital gain or loss
to the extent attributable to property held by the pass through trust for more
than one year. In the case of individuals, estates, and trusts, the maximum
U.S. federal income tax rate on long-term capital gains generally is 20%.

Foreign Certificateholders

   Under present U.S. federal income tax law, assuming certain certification
requirements are satisfied (which include identification of the beneficial
owner of a certificate), and subject to the discussion of backup withholding
below:

 .  interest paid (including any original issue discount) on a certificate
    to, or on behalf of, any beneficial owner of a certificate that is not a
    U.S. person will not be subject to U.S. federal income tax or withholding
    tax provided that (a) the non-U.S. certificateholder does not actually or
    constructively own 10% or more of the total combined voting power of all
    classes of stock of an Owner Participant or US Airways, (b) the non-U.S.
    certificateholder is not (A) a bank receiving interest pursuant to a loan
    agreement entered into in the ordinary course of its trade or business,
    or (B) a controlled foreign corporation for U.S. tax purposes that is
    related to an Owner Participant or US Airways, and (c) the interest
    payments are not effectively connected with the non-U.S.
    certificateholder's conduct of a U.S. trade or business; and

 .a non-U.S. certificateholder will not be subject to U.S. federal income tax
    on any capital gain realized on the sale, exchange or other disposition
    of a certificate, unless (a) the non-U.S. certificateholder is an
    individual who is present in the United States for 183 days or more
    during the taxable year of the sale or exchange and certain other
    requirements are met or (b) the gain is effectively connected with the
    non-U.S. certificateholder's conduct of a U.S. trade or business.

                                      S-91
<PAGE>

   The certification referred to above may be made on an IRS Form W-8 BEN (or
any successor form prescribed by the IRS) or substantially similar substitute
form.

Information Reporting and Backup Withholding

   In general, information reporting requirements will apply to certain
payments within the United States of principal, interest, original issue
discount and premium on the certificates, and to payments of the proceeds of
certain sales of certificates made to U.S. certificateholders other than
certain exempt recipients (such as corporations). A 31% backup withholding tax
may apply to the payments if the holder fails or has failed to provide an
accurate taxpayer identification number or otherwise establish an exemption or
fails to report in full interest income. With respect to non-U.S.
certificateholders, payments made on a certificate and proceeds from the sale
of a certificate owned by a non-U.S. certificateholder will generally not be
subject to information reporting requirements or the backup withholding tax if
the non-U.S. certificateholder provides the required certification of its non-
U.S. status or otherwise establishes an exemption.

   Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules will be allowed as a refund or credit against the
certificateholder's U.S. federal income tax liability, if any, provided the
required information is furnished to the IRS.

   The Treasury Department recently issued final regulations governing backup
withholding and information reporting requirements. The regulations do not
significantly alter the substantive withholding and information reporting
requirements discussed above; they unify current certification procedures and
forms and clarify reliance standards. The regulations will generally become
effective for payments made after December 31, 2000.

                           CERTAIN CONNECTICUT TAXES

   The pass through trustee is a national banking association with its
corporate trust office in Connecticut. Bingham Dana LLP, counsel to the pass
through trustee, has advised us that, in its opinion, under currently
applicable law, assuming that each pass through trust will not be taxable as a
corporation for federal income tax purposes, but, rather, will be classified
for such purposes as a grantor trust or as a partnership, (a) the pass through
trusts will not be subject to any tax (including, without limitation, net or
gross income, tangible or intangible property, net worth, capital, franchise or
doing business tax), fee or other governmental charge under the laws of the
State of Connecticut or any political subdivision thereof and (b) certificate
owners that are not residents of or otherwise subject to tax in Connecticut
will not be subject to any tax (including, without limitation, net or gross
income, tangible or intangible property, net worth, capital, franchise or doing
business tax), fee or other governmental charge under the laws of the State of
Connecticut or any political subdivision thereof as a result of purchasing,
owning (including receiving payments with respect to) or selling a certificate.

   Neither the pass through trust nor the certificate owners will be
indemnified for any state or local taxes imposed on them, and the imposition of
any such taxes on a pass through trust could result in a reduction in the
amounts available for distribution to the certificate owners of such pass
through trust. In general, should a certificate owner or a pass through trust
be subject to any state or local tax which would not be imposed if the pass
through trust were administered in a different jurisdiction in the United
States or if the pass through trustee were located in a different jurisdiction
in the United States, the pass through trustee will either relocate the
administration of the pass through trust to such other jurisdiction or resign
and, in the event of such a resignation, a new pass through trustee in such
other jurisdiction will be appointed.

                              ERISA CONSIDERATIONS

General

   The Employee Retirement Income Security Act of 1974, as amended ("ERISA"),
imposes certain requirements on employee benefit plans subject to Title I of
ERISA ("ERISA Plans"), and on those persons who are fiduciaries with respect to
ERISA Plans. Investments by ERISA Plans are subject to ERISA's general
fiduciary requirements, including, but not limited to, the requirement of
investment prudence and diversification and the requirement that an ERISA
Plan's investments be made in accordance with the documents governing the Plan.

   Section 406 of ERISA and Section 4975 of the Code prohibit certain
transactions involving the assets of an ERISA Plan (as well as those plans that
are not subject to ERISA but which are subject to Section 4975 of the Code,
such as individual retirement accounts (together with ERISA Plans, "Plans"))
and certain persons (referred to as "parties in interest" or "disqualified
persons") having certain relationships to such Plans, unless a statutory or
administrative exemption is applicable to the transaction. A party in interest
or disqualified person who engages in a prohibited transaction may be subject
to excise taxes and other penalties and liabilities under ERISA and the Code
and such transactions may have to be rescinded.

   Any Plan fiduciary which proposes to cause a Plan to purchase any
certificates should consult with its counsel regarding the applicability of the
fiduciary responsibility and prohibited transaction provisions of ERISA and
Section 4975 of the Code to such an investment, and to confirm that such
purchase and holding will not constitute or result in a non-exempt prohibited
transaction or any other violation of an applicable requirement of ERISA.

   Governmental plans and certain church plans, while not subject to the
fiduciary responsibility provisions of ERISA or the prohibited transaction
provisions of ERISA and Section 4975 of the Code, may nevertheless be subject
to state or other federal laws that are substantially similar to the foregoing
provisions of ERISA and the Code. Fiduciaries of any such plans should consult
with their counsel before purchasing any certificates.

Plan Assets Issues

   The Department of Labor has promulgated a regulation, 29 CFR Section 2510.3-
101 (the "Plan Assets Regulation"), describing what constitutes the assets of a
Plan with respect to the Plan's investment in an entity for purposes of ERISA
and Section 4975 of the Code. Under the Plan Assets Regulation, if a Plan
invests (directly or indirectly) in a certificate, the Plan's assets will
include both the certificate and an undivided interest in each of the
underlying assets of the corresponding pass through trust, including the
secured promissory notes held by such pass through trust, unless it is
established that equity participation in the pass through trust by benefit plan
investors (including but not limited to Plans and entities whose underlying
assets include Plan assets by reason of an employee benefit plan's investment
in the entity) is not "significant" within the meaning of the Plan Assets
Regulation. In this regard, the extent to which there is equity participation
in a particular pass through trust by, or on behalf of, employee benefit plans
will not be monitored. If the assets of a pass through trust are deemed to
constitute the assets of a Plan, transactions involving the assets and
operations of such pass through trust could be subject to the prohibited
transaction provisions of ERISA and Section 4975 of the Code.

Prohibited Transaction Exemptions

   In addition, whether or not the assets of a pass through trust are deemed to
be Plan assets under the Plan Assets Regulation, the fiduciary of a Plan that
proposes to purchase and hold any certificates should consider, among other
things, whether such purchase and holding may involve (i) the direct or
indirect extension of credit to a party in interest or a disqualified person,
(ii) the sale or exchange of any property between a Plan and a party in
interest or a disqualified person or (iii) the transfer to, or use by or for
the benefit of, a party in interest or a disqualified person, of any Plan
assets. Such parties in interest or disqualified persons could

                                      S-93
<PAGE>

include, without limitation, us and our affiliates, the Owner Participants, the
Underwriters, the pass through trustees, the Escrow Agent, the Depositary, the
Owner Trustees, the Policy Provider and the Liquidity Provider. Moreover, if
certificates are purchased by a Plan and certificates of a subordinate class
are held by a party in interest or a disqualified person with respect to such
Plan, the exercise by the holder of the subordinate class of certificates of
its right to purchase the senior classes of certificates upon the occurrence
and during the continuation of a Triggering Event could be considered to
constitute a prohibited transaction unless a statutory or administrative
exemption were applicable. See "Description of the Certificates--Purchase
Rights of Certificateholders." Depending on the identity of the Plan fiduciary
making the decision to acquire or hold certificates on behalf of a Plan,
Prohibited Transaction Class Exemption ("PTCE") 91-38 (relating to investments
by bank collective investment funds), PTCE 84-14 (relating to transactions
effected by a "qualified professional asset manager"), PTCE 95-60 (relating to
investments by an insurance company general account), PTCE 96-23 (relating to
transactions directed by an in-house professional asset manager) or PTCE 90-1
(relating to investments by insurance company pooled separate accounts)
(collectively, the "Class Exemptions") could provide an exemption from the
prohibited transaction provisions of ERISA and Section 4975 of the Code.
However, there can be no assurance that any of these Class Exemptions or any
other exemption will be available with respect to any particular transaction
involving the certificates or any transaction involving the assets of a pass
through trust.

   Each person who acquires or accepts a certificate or an interest therein,
will be deemed by such acquisition or acceptance to have represented and
warranted that either: (i) no Plan assets have been used to purchase such
certificate or an interest therein or (ii) the purchase and holding of such
certificate or interest therein are exempt from the prohibited transaction
restrictions of ERISA and Section 4975 of the Code pursuant to one or more
prohibited transaction statutory or administrative exemptions.

Underwriter Exemption May Apply to the Purchase of Class G Certificates by
Plans

   In addition to the Class Exemptions referred to above, an individual
exemption may apply to the purchase, holding and secondary market sale of class
G certificates by Plans, provided that certain specified conditions are met. In
particular, the Department of Labor has issued individual administrative
exemptions to the Underwriters which are substantially the same as the
administrative exemption issued to The First Boston Corporation, Prohibited
Transaction Exemption 89-90 (54 Fed. Reg. 42, 597 (1989), as amended (the
"Underwriter Exemption"). The Underwriter Exemption generally exempts from the
application of certain, but not all, of the prohibited transaction provisions
of Section 406 of ERISA and Section 4975 of the Code certain transactions
relating to the initial purchase, holding and subsequent secondary market sale
of pass through certificates which represent an interest in a trust that holds
secured credit instruments that bear interest or are purchased at a discount in
transactions by or between business entities (including secured promissory
notes secured by leases) and certain other assets, provided that certain
conditions set forth in the Underwriter Exemption are satisfied.

   The Underwriter Exemption sets forth a number of general and specific
conditions which must be satisfied for a transaction involving the initial
purchase, holding or secondary market sale of certificates representing a
beneficial ownership interest in a trust to be eligible for exemptive relief
thereunder. In particular, the Underwriter Exemption requires that the
acquisition of certificates by a Plan be on terms that are at least as
favorable to the Plan as they would be in an arm's-length transaction with an
unrelated party; the rights and interests evidenced by the certificates not be
subordinated to the rights and interests evidenced by other certificates of the
same trust estate; the certificates at the time of acquisition by the Plan be
rated in one of the three highest generic rating categories by Moody's,
Standard & Poor's, Duff & Phelps Inc. or Fitch; and the investing Plan be an
accredited investor as defined in Rule 501(a)(1) of Regulation D of the SEC
under the Securities Act.

   In addition, the trust corpus generally must be invested in qualifying
receivables, such as the secured promissory notes, but may not in general
include a pre-funding account (except for a limited amount of pre-funding which
is invested in qualifying receivables within a limited period of time following
the closing not to exceed three months).

                                      S-94
<PAGE>

   In reviewing the potential applicability of the Underwriter Exemption with
their legal advisors, Plans should note that an investment in a certificate
will evidence both an interest in the respective pass through trust as well as
an interest in the Deposits held in escrow by an Escrow Agent for the benefit
of the certificateholder. See "Description of the Deposit Agreement" and
"Description of the Escrow Agreement." Under the terms of the class G Escrow
Agreement, the proceeds from the offering of the class G certificates will be
paid over by the Underwriters to the Depositary on behalf of the Escrow Agent
(for the benefit of such certificateholders as the holders of the Escrow
Receipts) and will not constitute property of the class G pass through trust.
Under the terms of the Escrow Agreement, the Escrow Agent will be irrevocably
instructed to enter into the Deposit Agreement with the Depositary and to
effect withdrawals upon the receipt of appropriate notice from the relevant
pass through trustee so as to enable such pass through trustee to purchase the
identified secured promissory notes on the terms and conditions set forth in
the Note Purchase Agreement. Pending such withdrawals, the Deposit Agreement
will remain plan assets subject to the fiduciary responsibility and prohibited
transaction provisions of ERISA and Section 4975 of the Code.

   There can be no assurance that the Department of Labor would agree that the
Underwriter Exemption will be applicable to class G certificates in these
circumstances. In particular, the Department of Labor might assert that the
escrow arrangement is tantamount to an impermissible pre-funding rendering the
Underwriter Exemption inapplicable. In addition, even if all of the conditions
of the Underwriter Exemption are satisfied with respect to the class G
certificates, no assurance can be given that the Underwriter Exemption would
apply with respect to all transactions involving the class G certificates or
the assets of the class G pass through trust. In particular, the Underwriter
Exemption may not apply to the purchase by the class C certificateholders of
class G certificates in connection with the exercise of their rights upon the
occurrence and during the continuance of a Triggering Event. See "Description
of the Certificates--Purchase Rights of Certificateholders." Therefore, the
fiduciary of a Plan considering the purchase of a class G certificate should
also consider the availability of exemptive relief under any of the Class
Exemptions discussed above under "--Prohibited Transaction Exemptions."

   The Underwriter Exemption will not in any event apply to the class C
certificates, if any are issued.

Special Considerations Applicable to Insurance Company General Accounts

   Under a 1993 decision of the United States Supreme Court, insurance company
general accounts in which Plans have invested may themselves be treated as
holding Plan assets and deemed subject to ERISA's fiduciary requirements and
prohibited transaction rules. Any potential investor that is an insurance
company using assets of its general account should consider that decision as
well as the effects of Section 401(c) of ERISA and the regulations issued
thereunder by the Department of Labor on January 5, 2000.

                                  UNDERWRITING

   Subject to the terms and conditions set forth in the underwriting agreement
dated July 24, 2000, we have agreed to cause the pass through trust to sell to
each of the underwriters, the following respective aggregate amounts of the
certificates:

   Salomon Smith Barney Inc....................................     90,603,000
                                                                  ------------
     Total.....................................................   $362,414,000
                                                                  ============
</TABLE>

   The underwriting agreement provides that the underwriters are obligated to
purchase all of the certificates if any certificates are purchased. The
underwriting agreement provides that if an underwriter defaults, the purchase
commitments of non-defaulting underwriters may be increased or the offering of
the certificates may be terminated.

   The underwriters propose initially to offer the certificates at the public
offering price on the cover page of this prospectus supplement, and to the
selling group members at that price less a concession of 0.50% of the principal
amount per certificate. The underwriters and the selling group members may
allow a discount of 0.25% of the principal amount per certificate on sales to
other broker/dealers. After the initial public offering, the public offering
price and concession and discount may be changed.

   We estimate that our out of pocket expenses, including reimbursement of the
underwriters out of pocket expenses, will be approximately $1,250,000.

   We do not intend to apply for the listing of the certificates on a national
securities exchange, but have been advised by the underwriters that they
presently intend to make a market in the certificates, as permitted by
applicable laws and regulations. No underwriter is obligated, however, to make
a market in the certificates, and any market-making may be discontinued at any
time, at the sole discretion of the underwriter. Accordingly, no assurance can
be given as to the liquidity of, or trading markets for, the certificates.

   We have agreed to indemnify the underwriters against liabilities under the
Securities Act of 1933 or to contribute to payments which the underwriters may
be required to make in respect thereof.

   From time to time, one or more of the underwriters or their affiliates may
perform investment banking and advisory services for, and may provide general
financing and banking services to, us. In particular, (a) Credit Suisse First
Boston, New York Branch, an affiliate of Credit Suisse First Boston
Corporation; (b) Citicorp North America, Inc., an affiliate of Salomon Smith
Barney Inc.; (c) ABN AMRO Bank N.V., an affiliate of ABN AMRO Incorporated; and
(d) The Chase Manhattan Bank, an affiliate of Chase Securities Inc. are all
lenders in a syndicate group to US Airways under two revolving credit
facilities concluded on December 10, 1999. Salomon Smith Barney Inc. has been
retained by our parent company to act as financial advisor in connection with
the merger of US Airways Group, Inc. and a subsidiary of UAL Corporation. ABN
AMRO Bank N.V., an affiliate of ABN AMRO Incorporated, will act as Depositary
with respect to the class G certificates.

   The underwriters may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation
M under the Exchange Act of 1934.

  .  Over-allotment involves syndicate sales in excess of the offering size,
     which creates a syndicate short position.

                                      S-96
<PAGE>

  .  Stabilizing transactions permit bids to purchase the underlying security
     so long as the stabilizing bids do not exceed a specified maximum.

  .  Syndicate covering transactions involve purchases of the certificates in
     the open market after the distribution has been completed in order to
     cover syndicate short positions.

  .  Penalty bids permit the underwriters to reclaim a selling concession
     from a syndicate member when the certificates originally sold by such
     syndicate member are purchased in a syndicate covering transaction to
     cover syndicate short positions.

Such stabilizing transactions, syndicate covering transactions and penalty bids
may cause the prices of the certificates to be higher than they would otherwise
be in the absence of such transactions. These transactions, if commenced, may
be discontinued at any time.

   We expect that delivery of the certificates will be made against payment
therefor on or about the closing date specified on the cover page of this
prospectus supplement, which will be the seventh business day following the
date of pricing of the certificates (such settlement cycle being referred to as
"T+7"). Under Rule 15c6-1 of the SEC under the Securities Exchange Act of 1934,
trades in the secondary market generally are required to settle in three
business days, unless the parties to any such trade expressly agree otherwise.
Accordingly, purchasers who wish to trade certificates on the date of pricing
or the next three succeeding business days will be required, by virtue of the
fact that such certificates initially will settle in T+7, to specify an
alternate settlement cycle at the time of any trade to prevent a failed
settlement and should consult their own advisor.

                          NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

   The distribution of the certificates in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of certificates are effected. Accordingly, any resale of the
certificates in Canada must be made in accordance with applicable securities
laws which will vary depending on the relevant jurisdiction, and which may
require resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the certificates.

Representations of Purchasers

   Each purchaser of certificates in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such certificates without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchase has reviewed the text above under "Resale
Restrictions".

Rights of Action (Ontario Purchasers)

   The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

                                      S-97
<PAGE>

Enforcement of Legal Rights

   All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or persons outside of Canada.

Notice to British Columbia Residents

   A purchaser of certificates to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any such
certificates acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one such report
must be filed in respect of certificates acquired on the same date and under
the same prospectus exemption.

Taxation and Eligibility for Investment

   Canadian purchasers of certificates should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the
certificates in their particular circumstances and with respect to the
eligibility of the certificates for investment by the purchaser under relevant
Canadian legislation.

                                 LEGAL MATTERS

   The validity of the certificates is being passed upon for us by Skadden,
Arps, Slate, Meagher & Flom (Illinois) and its affiliates and for the
Underwriters by Milbank, Tweed, Hadley & McCloy LLP, New York, New York.
Skadden, Arps, Slate, Meagher & Flom (Illinois) and its affiliates and Milbank,
Tweed, Hadley & McCloy LLP will rely on the opinion of Bingham Dana LLP,
counsel for State Street Bank & Trust Company of Connecticut, National
Association, as pass through trustee, as to matters of Connecticut law relating
to the authorization, execution and delivery of the pass through trust
agreement and the certificates by State Street Bank & Trust Company of
Connecticut, National Association.

                                   GLOSSARY

   "Adjusted Expected Distributions" means, with respect to the certificates
on any Distribution Date (for purposes of this definition, the "Current
Distribution Date"), the sum of (1) accrued and unpaid interest on such
certificates (excluding interest, if any, payable with respect to the
Deposits) and (2) the greater of:

     (A) the difference between (x) the Pool Balance as of the immediately
  preceding Distribution Date (or, if the Current Distribution Date is the
  first Distribution Date, the original aggregate face amount of the
  certificates) and (y) the Pool Balance as of the Current Distribution Date
  calculated on the basis that (i) the principal of the Non-Performing
  Secured Promissory Notes held in the pass through trust has been paid in
  full and such payments have been distributed to the holders of
  certificates, (ii) the principal of the Performing Secured Promissory Notes
  held in pass through trust has been paid when due (but without giving
  effect to any acceleration of Performing Secured Promissory Notes) and such
  payments have been distributed to the holders of certificates and (iii) the
  principal of any secured promissory notes formerly held in the pass through
  trust that have been sold pursuant to the Intercreditor Agreement has been
  paid in full and such payments have been distributed to the holders of
  certificates, but without giving effect to any reduction in the Pool
  Balance as a result of any distribution attributable to Deposits, if any,
  occurring after the immediately preceding Distribution Date (or, if the
  Current Distribution Date is the first Distribution Date, occurring after
  the initial issuance of the certificates), and

     (B) the amount of the excess, if any, of (i) the Pool Balance as of the
  immediately preceding Distribution Date (or, if the Current Distribution
  Date is the first Distribution Date, the original aggregate face amount of
  the certificates), less the amount of the Deposits, if any, as of such
  preceding Distribution Date (or, if the Current Distribution Date is the

  promissory notes pursuant to the Note Purchase Agreement over (ii) the
  Aggregate LTV Collateral Amount for the Current Distribution Date;

provided that, until the date of the initial LTV Appraisals, clause (B) will
not apply.

   For purposes of calculating Adjusted Expected Distributions with respect to
the certificates, any premium paid on the secured promissory notes held in the
pass through trust that has not been distributed to the certificate holders
(other than such premium or a portion thereof applied to the payment of

              AISI Sight Unseen New Aircraft Base Value Appraisal, Sixteen
              A319-100 and Four A320-200 Aircraft.



Dear Mr. McDougle:

Aircraft Information Services, Inc. (AISI) is pleased to offer US Airways, Inc.,
our opinion of the sight unseen base market value of various new aircraft
scheduled to be delivered from the manufacturer between May 2000 and October
2000 as listed and defined in Table I.


1.    Methodology and Definitions
      ---------------------------

The standard terms of reference for commercial aircraft value are 'half-life
base market value' and `half-life current market value' of an 'average'
aircraft. Base value is a theoretical value that assumes a balanced market while
current market value is the value in the real market; both assume a hypothetical
average aircraft condition. AISI value definitions are consistent with the
current definitions of the International Society of Transport Aircraft Trading
(ISTAT), those of 01 January 1994. AISI is a member of that organization and
employs an ISTAT Certified and Senior Certified Aircraft Appraiser.

AISI defines a 'base value' as that of a transaction between equally willing and
informed buyer and seller, neither under compulsion to buy or sell, for a single
unit cash transaction with no hidden value or liability, and with supply and
demand of the sale item roughly in balance. Base values are typically given for
aircraft in 'new' condition, 'average half-life' condition, or in a specifically
described condition unique to a single aircraft at a specific time. An 'average'
aircraft is an operable airworthy aircraft in average physical condition and
with average

accumulated flight hours and cycles, with clear title and standard unrestricted
certificate of airworthiness, and registered in an authority which does not
represent a penalty to aircraft value or liquidity, with no damage history and
with inventory configuration and level of modification which is normal for its
intended use and age. AISI assumes average condition unless otherwise specified
in this report. 'Half-life' condition assumes that every component or
maintenance service which has a prescribed interval that determines its service
life, overhaul interval or interval between maintenance services, is at a
condition which is one-half of the total interval. It should be noted that AISI
and ISTAT value definitions apply to a transaction involving a single aircraft,
and that transactions involving more than one aircraft are often executed at
considerable and highly variable discounts to a single aircraft price, for a
variety of reasons relating to an individual buyer or seller.

AISI defines a 'current market value', which is synonymous with the older term
`fair market value' as that value which reflects the real market conditions,
whether at, above or below the base value conditions. Assumption of a single
unit sale and definitions of aircraft condition, buyer/seller qualifications and
type of transaction remain unchanged from that of base value. Current market
value takes into consideration the status of the economy in which the aircraft
is used, the status of supply and demand for the particular aircraft type, the
value of recent transactions and the opinions of informed buyers and sellers.
Current market value assumes that there is no short term time constraint to buy
or sell.

AISI encourages the use of base values to consider historical trends, to
establish a consistent baseline for long term value comparisons and future value
considerations, or to consider how actual market values vary from theoretical
base values. Base values are less volatile than current market values and tend
to diminish regularly with time. Base values are normally inappropriate to
determine near term values. AISI encourages the use of current market values to
consider the probable near term value of an aircraft.


2.    Valuation
      ---------

Following is AISI's opinion of the base market value for the subject aircraft on
their respective scheduled delivery dates in current US Dollars. Valuations are

                                                                   July 14, 2000


Mr. Jeffery McDougle
Vice President and Treasurer
US Airways, Inc.
2345 Crystal Drive
Arlington, Virginia  22227


Dear Mr. McDougle:

         AvSOLUTIONS is pleased to provide this opinion on the base value, as of
July 2000, of sixteen Airbus Industrie A319-100 aircraft and four Airbus
Industrie A320-200 aircraft (collectively, the "Aircraft"). The A319-100
aircraft are powered by CFM International CFM56-5B engines. The A320-200
aircraft are powered by CFM International CFM56-5B engines. The total of twenty
aircraft either have already been delivered or are anticipated to be delivered
to US Airways, Inc. (also referred to as "Client") before the end of the fourth
quarter of 2000. A listing of the A319-100 and A320-200 aircraft is provided as
Attachment 1 of this document.

         Set forth below is a summary of the methodology, considerations and
assumptions utilized in this appraisal.


BASE VALUE
----------

         Base value is the appraiser's opinion of the underlying economic value
of an aircraft in an open, unrestricted, stable market environment with a
reasonable balance of supply and demand, and assumes full consideration of its
"highest and best use". An aircraft's base value is founded in the historical
trend of values and in the projection of future value trends and presumes an
arm's length, cash transaction between willing, able and knowledge parties,
acting prudently, with an absence of duress and with a reasonable period of time
available for marketing.


CURRENT FAIR MARKET VALUE
-------------------------

         According to the International Society of Transport Aircraft Trading's
(ISTAT) definition of Fair Market Value (FMV), to which AvSOLUTIONS subscribes,
the quoted FMV is the appraiser's opinion of the most likely trading price that
may be generated for an aircraft under the market circumstances that are
perceived to exist at the time in question. The fair market value assumes that
the aircraft is valued for its highest and best use, that the parties to the
hypothetical sales transaction are willing, able, prudent and knowledgeable, and
under no unusual pressure for a prompt sale, and that the transaction would be
negotiated in an open and unrestricted market on an arm's length basis, for cash
equivalent consideration, and given an adequate amount of time for effective
market exposure to perspective buyers, which AvSOLUTIONS considers to be ten to
twenty months.

APPRAISAL METHODOLOGY
---------------------

         The method employed by AvSOLUTIONS to appraise the current values of
aircraft and the associated equipment addresses the factors that influence the
market value of an aircraft, such as its age, condition, configuration, the
population of similar aircraft, similar aircraft on the market, operating costs,
cost to acquire a new aircraft, and the state of demand for transportation
services.

         To achieve this objective, cross-sectional data concerning the values
of aircraft in each of several general categories is collected and analyzed.
Cross-sectional data is then postulated and compared with reported market values
at a specified point in time. Such data reflects the effect of deterioration in
aircraft performance due to usage and exposure to the elements, as well as the
effect of obsolescence due to the evolutionary development and implementation of
new designs and materials.

         The product of the analysis identifies the relationship between the
value of each aircraft and its characteristics, such as age, model designation,
service configuration and engine type. Once the relationship is identified, one
can then postulate the effects of the difference between the economic
circumstances at the time when the cross-sectional data were collected and the
current situation. Therefore, if one can determine the current value of an
aircraft in one category, it is possible to estimate the current values of all
aircraft in that category.

         The manufacturer and size of the aircraft usually determine the
specific category to which it is assigned. Segregating the world airplane fleet
in this manner accommodates the potential effects of different size and
different design philosophies.

         The variability of the data used by AvSOLUTIONS to determine the
current market values implies that the actual value realized will fall within a
range of values. Therefore, if a contemplated value falls within the specified
confidence range, AvSOLUTIONS cannot reject the hypothesis that it is a
reasonable representation of the current market situation.


LIMITING CONDITIONS AND ASSUMPTIONS
-----------------------------------

         In order to conduct this valuation, AvSOLUTIONS is solely relying on
information as supplied by US Airways, Inc. and from data within AvSOLUTIONS'
own database. In determining the base value of the subject Airbus A319-100 and
A320-200 Aircraft, the following assumptions have been researched and
determined:

1.   AvSOLUTIONS has not inspected these Aircraft or their maintenance records;
accordingly, AvSOLUTIONS cannot attest to their specific location or condition.

2.   The Aircraft either have already been delivered or are anticipated to be
delivered to US Airways, Inc. before the end of the fourth quarter of 2000.

3.   The Aircraft will be certified, maintained and operated under United States
Federal Aviation Regulation (FAR) part 121.

4.   All mandatory inspections and Airworthiness Directives have been complied
with.

5.   The Aircraft have no damage history.

6.   The Aircraft are in good condition.

7.   AvSOLUTIONS considers the economic useful life of these aircraft to be at
least 32 years.


         Based upon the above methodology, considerations and assumptions, it is
AvSOLUTIONS' opinion that the base values of each Aircraft are as listed in
attachment 1.

I. INTRODUCTION AND EXECUTIVE SUMMARY
--------------------------------------------------------------------------------

MORTEN BEYER & AGNEW, INC. (MBA), has been retained by US Airways, Inc (also
referred to as "Client") to determine the Current Base Value of (16) A319-100,
and (4) A320-200 aircraft delivered new. The aircraft are further identified in
Section II of this report.

Based on the information set forth further in this report, it is our opinion
that the Current Base Value of this portfolio is $786,430,000 as set forth in
Section IV.

MBA uses the definition of certain terms, such as Current Market Value and Base
Value, as promulgated by the Appraisal Program of International Society of
Transport Aircraft Trading (ISTAT), a non-profit association of management
personnel from banks, leasing companies, airlines, manufacturers, brokers, and
others who have a vested interest in the commercial aviation industry and who
have established a technical and ethical certification program for expert
appraisers.

ISTAT defines Current Market Value (CMV) as the appraiser's opinion of the most
likely trading price that may be generated for an aircraft under market
conditions that are perceived to exist at the time in question. Current Market
Value assumes that the aircraft is valued for its highest, best use; that the
parties to the hypothetical sale transaction are willing, able, prudent and
knowledgeable and under no unusual pressure for a prompt sale; and that the
transaction would be negotiated in an open and unrestricted market on an
arm's-length basis, for cash or equivalent consideration, and given an adequate
amount of time for effective exposure to prospective buyers.

The ISTAT definition of Base Value (BV) has, essentially, the same elements of
Market Value except that the market circumstances are assumed to be in a
reasonable state of equilibrium. Thus, Base Value pertains to an idealized
aircraft and market combination, but will not necessarily reflect the actual
Current Market Value of the aircraft in question. BV is founded in the
historical trend of values and is generally used to analyze historical values or
to project future values.

Airbus A319/ A320
-----------------------

Family Development

The A320 was Airbus' first all new design since the launch of the original A300
in 1971. The program was initiated in 1983 and logged almost 400 orders prior to
first delivery in 1988. The A320s are now offered with both the CFM-56 and the
IAE V-2500 engine, with the CFM version having a long head start, but the V2500
gaining. At 5/31/00, 816 A320s have been delivered and 571 more are on order.
The A320 has achieved a wide market base on all continents, with a total of 84
current operators.

The A319 is the opposite of the A321--that is, a truncated version of the
original aircraft. The program was officially launched with a modest
six-aircraft order by leasing giant ILFC in late 1992. Prospects were not
encouraging as more than one year went by before subsequent orders were placed.
However, Air Canada provided a major boost to Airbus with an order of 34 A319s
in April 1994 (all now delivered). Ironically, the carrier had reportedly
decided against ordering new aircraft to replace its aging DC-9 fleet when
Fokker Aircraft convinced the carrier to re-examine the benefits of new
airframes. ACA Chairman Hollis Harris agreed, but Fokker lost the battle to its
European competitor. As of the May of 2000, 664 A319s have been ordered, 233
delivered, and there are 350 outstanding orders.

The Northwest and Air Canada situations are significant due to the Airbus family
concept factor, (common type ratings and minimal differences training for pilots
of the A318 through A340 aircraft), which is the core of the manufacturer's goal
to develop entire fleets with major carriers. Air Canada, which operates A320s
already, chose this Airbus concept with both the A319 order and a 13-plane A340
order as well. Northwest Airlines, which operates 70 A320s (and has 12 on order)
ordered 68 A319s and switched their A340 order for 16 A330s for delivery beyond
2000.

Other carriers, including Air France Groupe and Lufthansa, have each ordered six
types of Airbuses, and currently operate 116 and 114 Airbus aircraft
respectively, and other major European operators are Swissair (54) and Iberia
(46). However, the European influence might tilt decision-makers at airlines
such as these. Airbus believes its concept will give its new designs significant
advantages over Boeing aircraft, and the 1999 order books indicate it is doing
just that. MBA believes the combination of extremely efficient designs and the
inherent savings in training and other costs make the Airbus family an
attractive avenue for an entire fleet refurbishment, as US Airways' commitment
for up to 400 narrowbody aircraft (including options) appears to justify.

The A320 family incorporates an increased amount of composites in its secondary
structure compared to older jets, a complete fly-by-wire control system, and a
computerized flight management system which, when engaged, virtually precludes
putting the aircraft into stalls or other extreme conditions. This system has
been blamed by some for two early incidents in which the crews placed the
aircraft in an untenable position close to the ground with the system
disconnected and from which it was unable to recover. These two aircraft were
totally cleared by the airworthiness authorities, as well as one involved in a
third incident in which the crew made a below-minimum approach in bad weather
and struck high ground. This third aircraft had no ground proximity warning
device installed, a device now required by the French government and long
required by many others. In general, all these components have held up well in
service, and the reliability of the aircraft has been excellent.

United's 1994 order for 50 A320s plus options (subsequently increased to 86) was
announced as a B-727 replacement, of which United operated 59 in mid 2000.
United has 32 A320s and 22 A319s on order. It is

obvious that other airlines will use their large orders to surplus older
aircraft as well. Alitalia, with 22 A321s in service and three on order, is
replacing its stable of MD-82s. As mentioned, Air Canada's commitments for the
A319 are rapidly replacing its fleet of DC-9s. Thus the advent of the A320
family is hastening the retirement of older, far less efficient jets. The A320s
currently in service are operating at seat mile costs as low as half of that for
older aircraft. The combination of all the above factors leads us to believe the
A320 family will enjoy a long production run and in-service useful life, with
strong residual values.

The A320 also offers the advantage of being able to carry seven LD-3 cargo
containers--a feat not even the B-767 can perform. The fuselage is approximately
10 inches wider than that of the B-727/B-737/B-757 series, offering wider aisles
and roomier seats--a feature much appreciated by passengers. There are no cargo
or Combi models currently offered by Airbus, although such a configuration is
obviously possible. The exception is the A300 `Beluga' outsized special cargo
aircraft, which is already being leased for commercial applications but is
primarily in service for Airbus.

Economics

The A320 vies with the B-757 for top honors as the most efficient aircraft in
service. Great fuel efficiency, new technology design and low operating cost
parameters all combine to give these aircraft among the lowest seat mile costs
of any being built or in service. The MBA Model indicates that both will produce
very satisfactory operating and net ratios well into the next century.

* Base Value includes adjustment for additional MTOW.

In developing the Base Value of this aircraft, MBA did not inspect the aircraft
nor its historical maintenance documentation, but relied on partial information
supplied by the Client. Therefore, we used certain assumptions that are
generally accepted industry practice to calculate the value of aircraft when
more detailed information is not available. The principal assumptions are as
follows for each aircraft:

     1.  The aircraft is delivered new.
     2.  The specifications of the aircraft are those most common for an
         aircraft of this type new delivery.
     3.  The aircraft is in a standard airline configuration.
     4.  Its modification status is comparable to that most common for an
         aircraft of its type and vintage.
     5.  No accounting is made for lease obligations or terms of ownership.

                                    SUMMARY

The Offering

   This prospectus and each supplement to this prospectus describe US Airways'
offering of pass through trust certificates to help finance or refinance
aircraft that we own or lease. Our parent, US Airways Group may guarantee some
of our obligations relating to the certificates. For convenience, throughout
this prospectus, the words we, us, ours or similar words refer to US Airways
and the words parent, parent guarantor or other similar words refer to US
Airways Group.

   The remainder of this prospectus and the related prospectus supplement will
describe the offering of the pass through certificates in more detail. We will
begin by describing the pass through certificates and the pass through trusts
that issue the pass through certificates. We will also describe the various
agreements relating to the certificates. This prospectus then describes the
secured promissory notes that the pass through trusts will acquire and, in the
case of promissory notes secured by aircraft leased to us, the owner trusts
that issue those secured promissory notes.

Certificates

   We may offer and sell pass through certificates from time to time by this
prospectus. For convenience, we may:

  .  refer to "pass through certificates" as "certificates;" and

  .  refer to the holder of a "pass through certificate" as a
     "certificateholder."

   Pass through certificates are securities that evidence an ownership interest
in a pass through trust. The holders of the certificates issued by a pass
through trust will be the beneficiaries of that trust. A certificateholder's
beneficial interest in a pass through trust will be a pro rata interest in the
property of that trust equal to the ratio of the value of all of the
certificates owned by the holder to the value of all of the certificates issued
by that trust. Each certificate will represent a beneficial interest only in
the property of the pass through trust that issued the certificate. A
certificate will not represent an interest in, or rights to, the property of
any pass through trust other than the pass through trust that issued the
certificate.

   Multiple series of certificates may be issued. If more than one series of
certificates is issued, each series of certificates will be issued by a
separate pass through trust. The economic terms of any series of certificates
will be described in the prospectus supplement relating to that series of
certificates.

   The prospectus supplement relating to a series of certificates will be
delivered with this prospectus. The prospectus supplement will describe, among
other things, the property that will be held by each pass through trust. This
property will include promissory notes secured by aircraft we own or lease.
Payments of principal and interest on the secured promissory notes owned by a
pass through trust will be passed through to holders of certificates issued by
that trust in accordance with the terms of the pass through trust agreement
pursuant to which the trust was formed.

   If certificates of any series are entitled to the benefits of a liquidity
facility or other form of credit enhancement, the prospectus supplement
relating to that series will describe the terms of the liquidity facility or
other form of credit enhancement. A liquidity facility is a revolving credit
agreement, letter of credit, bank guarantee, insurance policy or other
instrument or agreement that will increase the likelihood that the
certificateholders will receive timely payments of interest in respect of the
certificates. While a liquidity facility is designed to increase the likelihood
of the timely payment of interest, it is not a guarantee of the timely or
ultimate payment of principal.

   We may offer and sell up to $1,500,000,000 of aggregate initial offering
price of certificates pursuant to this prospectus and related prospectus
supplements. The initial offering price may be denominated in United States
dollars or foreign currencies based on the applicable exchange rate at the time
of sale.

                                       2

Pass Through Trusts

   We will form a separate pass through trust to issue each series of
certificates. Each pass through trust will be formed by us, as creator of each
pass through trust, and a national or state bank or trust company, as trustee.
Each pass through trust will be governed by a trust instrument that creates the
trust and sets forth the powers of the trustee and the rights of the
beneficiaries. The trust instrument for each pass through trust will consist of
a basic pass through trust agreement among us, our parent and the pass through
trustee and a supplement to the basic pass through trust agreement. In the
event our parent does not guarantee any certificates, it may be released from
the basic pass through trust agreement.

   Unless otherwise stated in a prospectus supplement, State Street Bank and
Trust Company of Connecticut, National Association will be the trustee of each
pass through trust. The performance and obligations of State Street Bank and
Trust Company of Connecticut, N.A., under the pass through trust agreement will
be guaranteed by its parent, State Street Bank and Trust Company.

   Each pass through trust will pass through to holders of its certificates
payments that it receives on the property that it owns. The property of each
pass through trust may consist of:

  .  secured promissory notes of one or more series; and

  .  other property described in the applicable prospectus supplement.

Secured Promissory Notes

   The secured promissory notes owned by a pass through trust may consist of
any combination of:

  .  Promissory notes issued by an owner trust and secured by an aircraft
     owned by that trust and leased to us. We refer to these types of secured
     promissory notes as leased aircraft notes.

  .  Promissory notes issued by us and secured by an aircraft owned by us. We
     refer to these types of secured promissory notes as owned aircraft
     notes.

   Leased Aircraft Notes. Except as specified in a prospectus supplement,
leased aircraft notes will be issued by a bank, trust company, financial
institution or other entity solely in its capacity as owner trustee in a
leveraged lease transaction. In a leveraged lease transaction, one or more
persons will form an owner trust to acquire an aircraft and then that owner
trust will lease the aircraft to us. In the leasing industry, the person that
is the beneficiary of the owner trust is referred to as an owner participant.
The owner participant will contribute a portion of the purchase price of the
aircraft to the owner trust. The transaction is called a "leveraged" lease
because the remainder of the owner trust's purchase price of the aircraft is
financed through the issuance of indebtedness in the form of leased aircraft
notes. Leased aircraft notes may also be issued to refinance an aircraft
previously financed in a leveraged lease transaction or otherwise.

   These leased aircraft notes are issued pursuant to a separate indenture and
security agreement between the owner trustee and a bank, trust company,
financial institution or other entity, as loan trustee. The loan trustee under
a leased aircraft indenture will act as a trustee for the holders of the leased
aircraft notes issued under that leased aircraft indenture.

   In a leveraged lease transaction, we will pay or advance rent and other
amounts to the owner trustee in its capacity as lessor under the lease. The
owner trustee will use the payments and certain other amounts received by it to
make payments of principal and interest on the leased aircraft notes. The owner
trustee also will assign its rights to receive basic rent and certain other
payments to the loan trustee as security for its obligations to pay principal
of, premium, if any, and interest on the secured promissory notes. Payments or
advances made under a lease and related agreements will at all times be
sufficient to make scheduled payments of principal of, and interest on, the
leased aircraft notes issued to finance the aircraft subject to that lease. Our
obligations under a lease and related agreements may be guaranteed by our
parent. If our parent guarantees our obligations under a lease or any related
agreement, the terms of the guarantee will be described in the applicable
prospectus supplement.

                                       3
<PAGE>

   We will not have any obligation to pay principal of, or interest on, the
leased aircraft notes. Holders of leased aircraft notes will not have recourse
against us or our parent if it guarantees the related lease or any other
agreement, for the payment of principal of, or interest on, the leased aircraft
notes.

   Owned Aircraft Notes. We may finance or refinance aircraft that we own
through the issuance of owned aircraft notes. Owned aircraft notes relating to
an owned aircraft will be issued under a separate indenture and security
agreement relating to that owned aircraft. Each separate indenture and security
agreement relating to owned aircraft notes will be between us and a bank, trust
company, financial institution or other entity, as loan trustee. The indenture
and security agreement entered into in connection with the issuance of owned
aircraft notes will be referred to as an owned aircraft indenture. The loan
trustee under an owned aircraft indenture will act as a trustee for the holders
of the owned aircraft notes issued under that owned aircraft indenture. Our
obligation to pay principal of, and interest on, the owned aircraft notes may
be guaranteed by our parent. If our parent guarantees the payment of principal
of, and interest on, the owned aircraft notes, we will describe the terms of
the guarantee in the applicable prospectus supplement.

   Holders of owned aircraft notes will have recourse against us and, if it
guarantees the lease, our parent, for payment of principal of, and interest on,
the owned aircraft notes.

   Because we often refer to owned aircraft indentures and leased aircraft
indentures together, we sometimes refer to them collectively as the indentures.

Delayed Financing

   If any portion of the proceeds of an offering of a series of certificates is
not used to purchase secured promissory notes on the date the certificates are
issued, those proceeds will be temporarily invested in other property such as
short-term securities or will be invested with a depositary or held in an
escrow arrangement pending the purchase of secured promissory notes. These
arrangements and this additional property will be described in the prospectus
supplement.

Cash Flow Structure

   Set forth below is a diagram illustrating the cash flows relating to the
certificates. This diagram assumes that the pass through trustees enter into an
intercreditor agreement, but does not include the effect of any liquidity
facility or similar credit enhancements or prefunding arrangements, each of
which will be described in the prospectus supplement if they are applicable.

Transaction Structure for Leased Aircraft

   Set forth below is a diagram illustrating cash flows that we expect to occur
on the closing date for a leveraged lease financing. We anticipate that
separate transactions similar to the transaction illustrated in the diagram
will occur for each leased aircraft financed with the proceeds of the offering
of the certificates. The structure illustrated below may change, in which case
a revised diagram will be included in the prospectus supplement.

Transaction Structure for Owned Aircraft

   Set forth below is a diagram illustrating cash flows that we expect to occur
on the closing date for an owned aircraft financing. We anticipate that
separate transactions similar to the transaction illustrated in the diagram
will occur for each owned aircraft financed with the proceeds of the offering
of the certificates. The structure illustrated below may change, in which case
a revised diagram will be included in the prospectus supplement.


Additional Information

   We will describe the specific terms of each series of certificates that we
may offer and sell from time to time in a prospectus supplement.

*  For the year ended December 31, 1994, US Airways' earnings were not
   sufficient to cover its fixed charges. Additional earnings of $721 million
   would have been required to achieve a ratio of earnings to fixed charges of
   1.0.
** For the year ended December 31, 1994, US Airways Group's earnings were not
   sufficient to cover its fixed charges. Additional earnings of $690 million
   would have been required to achieve a ratio of earnings to fixed charges of

   For purposes of calculating the ratios of earnings to fixed charges,
earnings consist of pretax income, fixed charges, capitalized interest and
amortization of previously capitalized interest. Fixed charges consist of
interest expense, amortization of debt issue expense and the portion of rental
expense representative of interest expense.

                                USE OF PROCEEDS

   Except as set forth in the applicable prospectus supplement, each pass
through trustee will use the proceeds from the sale of certificates issued by
its pass through trust to purchase one or more secured promissory notes.

   If an owner trustee issues the secured promissory notes, the owner trustee
will use the proceeds of the sale of the secured promissory notes to finance a
portion of the purchase price of an aircraft or to refinance indebtedness or
equity interests previously issued in respect of an aircraft. Upon the purchase
of an aircraft by an owner trustee, the aircraft will be leased by the owner
trustee to us.

   If we issue the secured promissory notes, we will use the proceeds from the
sale of the secured promissory notes to finance the purchase of an aircraft
which we will own or to refinance indebtedness or equity interests previously
issued in respect of an aircraft.

   If a pass through trustee does not use all of the proceeds of any offering
of certificates to purchase secured promissory notes on the date those
certificates are issued, the proceeds of the offering not used to purchase
secured promissory notes will be held for the benefit of the certificateholders
under arrangements that we will describe in the applicable prospectus
supplement. If the pass through trustee does not use a portion of the proceeds
to purchase secured promissory notes by the date specified in the applicable
prospectus supplement, it will return the unused portion of the proceeds to the
certificateholders.

   In addition, we may offer certificates subject to delayed aircraft financing
arrangements. For example, we may cause the proceeds from the sale of
certificates to be invested with a depositary or cause the proceeds to be held
in an escrow arrangement until they are used to purchase secured promissory
notes. In these circumstances, we will describe in the applicable prospectus
supplement how the proceeds of the certificates will be held or applied during
any delayed aircraft financing period, including any depositary or escrow
arrangement.

                        DESCRIPTION OF THE CERTIFICATES

   The following description is a summary of the terms of the certificates that
we expect will be common to all series of certificates. We will describe the
financial terms and other specific terms of any series of certificates in a
prospectus supplement. Since the terms of a specific series of certificates may
differ from the general information provided below, you should rely on the
information in the prospectus supplement instead of the information in this
prospectus if the information in the prospectus supplement is different from
the information below. To the extent that any provision in any prospectus
supplement is inconsistent with any provision in this summary, the provision of
the prospectus supplement will control.

   Because the following description is a summary, it does not describe every
aspect of the certificates, and it is subject to and qualified in its entirety
by reference to all the provisions of the pass through trust agreement and the
applicable supplements to the pass through trust agreement. For convenience, we
will refer to the pass through trust agreement among the pass through trustee,
our parent guarantor and us as the "Basic Agreement," and to the Basic
Agreement as supplemented by the applicable supplements as the pass through
trust agreement. The form of Basic Agreement has been filed as an exhibit to
the registration statement of which this prospectus is a part. The supplement
to the Basic Agreement relating to each series of certificates and the forms of
the other agreements described in this prospectus and the applicable prospectus
supplement will be filed as exhibits to a post-effective amendment to the
registration statement of which this prospectus is a part, a Current Report on
Form 8-K, a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K, as
applicable, filed by us or our parent guarantor with the SEC.

General

   Except as amended by a supplement to the Basic Agreement, the terms of the
Basic Agreement generally will apply to all of the pass through trusts that we
form to issue certificates by this prospectus. We will create a

                                       9
<PAGE>

separate pass through trust for each series of certificates by entering into a
separate supplement to the Basic Agreement. Each supplement to the Basic
Agreement will contain the additional terms governing the specific pass through
trust to which it relates and, to the extent inconsistent with the Basic
Agreement, will supersede the Basic Agreement.

   Certificates will be issued pursuant to the pass through trust agreement.
Unless otherwise stated in the applicable prospectus supplement, each pass
through certificate will be issued in minimum denominations of $1,000 or a
multiple of $1,000.

   Each certificate will represent a fractional undivided interest in the
property of the pass through trust that issued the pass through certificate.
All payments and distributions made on or with respect to a pass through
certificate will be made only from the property owned by the pass through trust
that issued the pass through certificate. The certificates do not represent an
interest in or obligation of US Airways, US Airways Group, the pass through
trustee, any of the owner trustees or loan trustees, in their individual
capacities, or any owner participant. Each holder of a pass through certificate
will be deemed to agree to look solely to the income and proceeds from the
property of the pass through trust as provided in the pass through trust
agreement.

   The property of each pass through trust for which a series of certificates
will be issued will include:

  .  the secured promissory notes held in the pass through trust;

  .  all monies at any time paid on or with respect to secured promissory
     notes held by the pass through trust;

  .  all monies due and to become due under the secured promissory notes held
     by the pass through trust;

  .  if so specified in the relevant prospectus supplement, rights under any
     escrow arrangement to withdraw the proceeds from escrow either to
     purchase secured promissory notes or to return unused proceeds to the
     holders of that series of certificates;

  .  funds from time to time deposited with the pass through trustee in
     accounts relating to that pass through trust; and

  .  if so specified in the relevant prospectus supplement, rights under
     intercreditor agreements relating to cross-subordination arrangements
     and monies receivable under a liquidity facility.

   As described in more detail below, the rights of a pass through trust to
receive monies due or to become due under secured promissory notes held by that
pass through trust may be subject to the effect of any cross-subordination
provisions contained in an intercreditor agreement described in the prospectus
supplement for a series of certificates.

   An intercreditor agreement refers to an agreement among the pass through
trusts and, if applicable, a liquidity provider under a liquidity facility, as
creditors of the issuers of the secured promissory notes owned by the pass
through trusts. An intercreditor agreement will set forth the terms and
conditions upon which payments made on or in respect of the secured promissory
notes and payments made under any liquidity facility will be received, shared
and distributed among the several pass through trusts and the liquidity
provider. In addition, the intercreditor agreement will set forth agreements
among the pass through trusts and the liquidity provider relating to the
exercise of remedies under the secured promissory notes and the indentures.

   Cross-subordination refers to a concept where payments on a junior class of
secured promissory notes issued under one indenture are distributed to a pass
through trust that holds a senior class of promissory notes issued under a
different indenture. The effect of this distribution mechanism is that holders
of a junior class of promissory notes issued under one indenture will not
actually receive payments made on or with respect to that junior class of
promissory notes until the holders of senior classes of promissory notes issued
under other indentures have received all scheduled payments on their notes.


                                       10

   Secured promissory notes owned by a pass through trust may be leased
aircraft notes, owned aircraft notes or a combination of leased aircraft notes
and owned aircraft notes.

   Leased aircraft notes will be issued in connection with the leveraged lease
of an aircraft to us. Except as set forth in the applicable prospectus
supplement, each leased aircraft will be leased to us under a lease between
us, as lessee, and an owner trustee, as lessor. Each owner trustee will issue
leased aircraft notes on a non-recourse basis under a separate leased aircraft
indenture between it and the applicable loan trustee. The owner trustee will
use the proceeds of the sale of the leased aircraft notes to finance or
refinance a portion of the purchase price paid or to be paid by the owner
trustee for the applicable leased aircraft. The owner trustee will obtain the
remainder of the funding for the leased aircraft from an equity contribution
from the owner participant that is the beneficiary of the owner trust and, to
the extent set forth in the applicable prospectus supplement, additional debt
secured by the applicable leased aircraft or other sources. A leased aircraft
also may be subject to other financing arrangements. Generally, neither the
owner trustee nor the owner participant will be personally liable for any
principal or interest payable under any leased aircraft indenture or any
leased aircraft notes. In some cases, an owner participant may be required to
make payments to an owner trustee that are to be used by the owner trustee to
pay principal of, and interest on, the secured promissory notes. If an owner
participant is required to make payments to be used by an owner trustee to pay
principal of, and interest on, the secured promissory notes and the owner
participant fails to make the payment, we will be required to provide the
owner trustee with funds sufficient to make the payment. We will make payments
or advances under a lease and the related documents sufficient to pay when due
all scheduled principal and interest payments on the leased aircraft notes
issued to finance the aircraft subject to that lease. Our parent may guarantee
our obligations under the leases and related agreements.

   We will issue owned aircraft notes under separate owned aircraft
indentures. Owned aircraft notes will be issued in connection with the
financing or refinancing of an aircraft that we own. Owned aircraft notes will
be obligations that have recourse to us and the related aircraft. Our parent
may guarantee payments of principal of, and interest on, owned aircraft notes.
Any owned aircraft may secure additional debt or be subject to other financing
arrangements.

   An indenture may provide for the issuance of multiple series of secured
promissory notes. If an indenture provides for multiple series of secured
promissory notes, it may also provide for differing priority of payments among
the different series. All secured promissory notes issued under an indenture
that are entitled to the same priority of payment will be referred to as a
"class." Secured promissory notes issued under an indenture may be held in
more than one pass through trust, and one pass through trust may hold secured
promissory notes issued under more than one indenture. Unless otherwise
provided in a prospectus supplement, only secured promissory notes of a single
class may be held in the same pass through trust.

   Except as set forth in the prospectus supplement for any series of
certificates, interest payments on the secured promissory notes held by a pass
through trust will be passed through to the registered holders of certificates
of that pass through trust at the annual rate shown on the cover page of the
prospectus supplement for the certificates issued by that pass through trust.
The certificateholders' right to receive payments made in respect of the
secured promissory notes is subject to the effect of any cross-subordination
provisions described in the prospectus supplement for a series of
certificates.

   We refer you to the prospectus supplement that accompanies this prospectus
for a description of the specific series of certificates being offered by this
prospectus and the applicable prospectus supplement, including:

  .  the specific designation, title and amount of the certificates;

  .  the initial public offering price, amounts payable on and distribution
     dates for the certificates;

  .  the currency or currencies (including currency units) in which the
     certificates may be denominated;

  .  the specific form of the certificates, including whether or not the
     certificates are to be issued in accordance with a book-entry system;

<PAGE>

  .  a description of the secured promissory notes to be purchased by the
     pass through trust issuing that series of certificates, including (a)
     the period or periods within which, the price or prices at which, and
     the terms and conditions upon which the secured promissory notes may or
     must be redeemed or defeased in whole or in part, by us or an owner
     trustee, (b) the payment priority of the secured promissory notes in
     relation to any other secured promissory notes issued with respect to
     the related aircraft and (c) any intercreditor or other rights or
     limitations between or among the holders of secured promissory notes of
     different priorities issued with respect to the same aircraft;

  .  a description of the aircraft to be financed with the proceeds of the
     issuance of the secured promissory notes;

  .  a description of the note purchase agreement setting forth the terms and
     conditions upon which that pass through trust will purchase secured
     promissory notes;

  .  a description of the indentures under which the secured promissory notes
     to be purchased by that pass through trust will be issued;

  .  a description of the events of default, the remedies exercisable upon
     the occurrence of such events of default and any limitations on the
     exercise of such remedies under the indentures pursuant to which the
     secured promissory notes to be purchased by that pass through trust will
     be issued;

  .  if the certificates relate to leased aircraft, a description of the
     leases to be entered into by the owner trustees and us, including (a)
     the names of the owner trustees that will own the leased aircraft and
     lease the leased aircraft to us and (b) a description of the events of
     default under the leases and, the remedies exercisable upon an event of
     default;

  .  if the certificates relate to leased aircraft, a description of the
     provisions of the leased aircraft indentures governing (a) the rights of
     the related owner trustee and/or owner participant to cure our failure
     to pay rent under the leases and (b) any limitations on the exercise of
     remedies with respect to the leased aircraft notes;

  .  if the certificates relate to leased aircraft, a description of the
     participation agreements that will set forth the terms and conditions
     upon which the owner participant, the owner trustee, the pass through
     trustees, the loan trustee and we agree to enter into a leveraged lease
     transaction;

  .  if the certificates relate to an owned aircraft, a description of the
     participation agreements that will set forth the terms and conditions
     upon which the applicable pass through trustees, the loan trustee and we
     agree to enter into a financing transaction for the owned aircraft;

  .  a description of the limitations, if any, on amendments to leases,
     indentures, pass through trust agreements, participation agreements and
     other material agreements entered into in connection with the issuance
     of secured promissory notes;

  .  a description of any cross-default provisions in the indentures;

  .  a description of any agreement among the holders of secured promissory
     notes and any liquidity provider governing the receipt and distribution
     of monies with respect to the secured promissory notes and the
     enforcement of remedies under the indentures, including a description of
     any applicable intercreditor and cross-subordination arrangements;

  .  a description of any cross-collateralization provisions in the
     indentures;

  .  a description of any liquidity facility or other credit enhancement
     relating to the certificates;

  .  if the certificates relate to aircraft that have not yet been delivered
     or financed, a description of any deposit or escrow agreement or other
     arrangement providing for the deposit and investment of funds pending
     the purchase of secured promissory notes and the financing of an owned
     aircraft or leased aircraft;

  .  a description of any guarantee of our obligation to make payments with
     respect to a leased aircraft or to make principal and interest payments
     with respect to owned aircraft notes;


                                       12
<PAGE>

  .  the names of the underwriters, dealers or agents, if any, through or to
     which we will sell the certificates, the compensation, if any, of
     underwriters, dealers or agents and the net proceeds from the offering
     of the certificates;

  .  the material United States federal income tax considerations applicable
     to the certificates; and

  .  any other special terms pertaining to the certificates.

   The concept of cross-default mentioned above refers to a situation where a
default under one indenture or lease automatically triggers a default under
other indentures or leases. We currently do not expect any indentures or leases
to contain cross-default provisions. The concept of cross-collateralization
mentioned above refers to the situation where an aircraft mortgaged to secure
obligations incurred under one indenture also serves as collateral for
obligations under one or more other indentures. If the indentures that are
cross-collateralized relate to aircraft that we lease, the lease assigned to a
loan trustee to secure obligations under one indenture may also serve as
collateral under one or more other indentures. We currently do not expect any
indentures to be cross-collateralized.

   If any certificates are denominated in one or more foreign currencies or
currency units, the restrictions, certain United States federal income tax
considerations, specific terms and other information with respect to the
certificates and the foreign currency or currency units will be set forth in
the applicable prospectus supplement.

Payments and Distributions

   We will make rental and other payments and advances for a leased aircraft
under the lease and other documents relating to that leased aircraft. In order
to secure its obligations to pay the principal of, and interest on, the leased
aircraft notes issued to finance or refinance a portion of the purchase price
of a leased aircraft, the applicable owner trustee will assign the scheduled
rental payments under the lease and may assign certain other payments or
advances under other related documents to the applicable loan trustee. As is
customary in the leveraged leasing industry, indemnities, insurance and similar
payments due under a lease and other documents may be excluded from any
assignment. Pursuant to the terms of the applicable indenture, the loan trustee
will, on behalf of the applicable owner trustee, apply the proceeds of the
payments and advances assigned to the loan trustee to make the corresponding
scheduled payments of principal of, and interest on, the leased aircraft notes
issued under that indenture. The loan trustee will distribute payments of
principal of, and interest on, the leased aircraft notes to the pass through
trustee for each pass through trust that holds those leased aircraft notes.
After the loan trustee has made all scheduled payments of principal of, and
interest on, the leased aircraft notes issued under the applicable indenture,
the loan trustee will, except under certain circumstances, pay the remaining
balance, if any, to the owner trustee for the benefit of the owner participant.
Distribution of payments by a loan trustee to a pass through trustee may be
affected by the terms of an intercreditor agreement.

   We will make scheduled payments of principal of, and interest on, the unpaid
amount of the owned aircraft notes to the loan trustee under the indenture
pursuant to which those owned aircraft notes were issued. The loan trustee will
distribute payments of principal of, and interest on, the owned aircraft notes
to the pass through trustee for each pass through trust that holds those owned
aircraft notes.

   Each certificateholder will be entitled to receive a pro rata share of any
distribution in respect of payments of principal of, and interest on, the
secured promissory notes held in the pass through trust that issued its
certificate. A pass through trustee's right to receive payments distributed by
a loan trustee may be affected by the terms of an intercreditor agreement. The
terms of any intercreditor agreement and any cross-subordination will be in the
prospectus supplement relating to a series of certificates.

   Each pass through trust will receive scheduled payments of principal of, and
interest on, the secured promissory notes held by it and will, in turn,
distribute those scheduled payments to its certificateholders on the

                                       13
<PAGE>

regular distribution dates and in the currencies specified in the prospectus
supplement relating to its certificates. However, a pass through trust may not
be able to distribute scheduled payments of principal and interest to its
certificateholders as scheduled in the prospectus supplement if the secured
promissory notes held by the pass through trust are in default or if payments
are diverted to other pass through trusts in accordance with an intercreditor
agreement. In addition to distributions of scheduled payments of principal and
interest on regular distribution dates, if the applicable series of
certificates is entitled to the benefits of a liquidity facility, the pass
through trustee will also distribute on a regular distribution date payments
received as a result of a drawing or other payments made under a liquidity
facility. The prospectus supplement relating to the certificates will describe
the terms of any liquidity facility or other form of credit enhancement.

   A pass through trustee may from time to time receive payments of principal
of, and interest on, secured promissory notes on dates other than scheduled
payment dates. These special payments may occur if the secured promissory notes
owned by the pass through trust are sold or redeemed early, or if a scheduled
payment is paid more than five days late. Each pass through trustee will
distribute special payments to its certificateholders on dates determined as
described in the applicable prospectus supplement. In the event a special
payment is received by a pass through trustee, the pass through trustee will
mail a notice to its certificateholders of record stating the anticipated
distribution date for the payment. Scheduled payments that are not more than
five days late will be treated as regular payments and paid to
certificateholders of record on the regular distribution dates.

   If any regular distribution date or special distribution date is not a
business day, distributions scheduled to be made on that date may be made on
the next succeeding business day without additional interest.

Pool Factors

   Unless otherwise described in the applicable prospectus supplement, the
"pool balance" for each pass through trust or for the certificates issued by
any pass through trust indicates, as of any date, the portion of the original
aggregate face amount of the certificates issued by that pass through trust
that has not been distributed to certificateholders. The pool balance for each
pass through trust as of any distribution date will be computed after giving
effect to any distribution to certificateholders to be made on that date.

   Unless otherwise described in the applicable prospectus supplement, the
"pool factor" for a pass through trust as of any distribution date for that
trust is the quotient (rounded to the seventh decimal place) computed by
dividing (a) the pool balance by (b) the aggregate original face amount of the
certificates issued by that pass through trust. The pool factor for a pass
through trust as of any distribution date will be computed after giving effect
to the payment of principal, if any, on the secured promissory notes or other
property of that pass through trust and distribution to certificateholders of
the payment of principal to be made on that date. The pool factor for a pass
through trust initially will be 1.0000000. The pool factor for a pass through
trust will decline as described in this prospectus and the related prospectus
supplement to reflect reductions in the pool balance of that pass through
trust. As of any distribution date for a pass through trust, certificateholder
will have a pro rata share of the pool balance of that pass through trust equal
to the product obtained by multiplying the original denomination of the
holder's pass through certificate by the pool factor for the pass through trust
that issued that pass through certificate.

   Each pass through trust will have a separate pool factor. We expect the pool
factor for each pass through trust to decline in proportion to the scheduled
repayments of principal on the secured promissory notes held by that pass
through trust. However, the pool factor for a pass through trust will not
decline in proportion to scheduled repayments of principal if there is an early
redemption or purchase of secured promissory notes held by a pass through trust
or if a default occurs in the repayment of secured promissory notes held by a
pass through trust. In the event of a redemption, purchase or default, the pool
factor and the pool balance of each pass through trust affected by the
redemption, purchase or default will be recomputed.

                                       14

Reports to Certificateholders

   The pass through trustee will include with each distribution to
certificateholders a statement setting forth the following information:

  .  the amount of the distribution allocable to principal and the amount
     allocable to premium, if any;

  .  the amount of the distribution allocable to interest;

  .  the pool balance and the pool factor for the pass through trust after
     giving effect to the distribution; and

  .  any additional or different information as may be described in the
     applicable prospectus supplement.

   As long as the certificates are registered in the name of DTC or its
nominee, on the record date prior to each distribution to certificateholders,
the pass through trustee will request from DTC a securities position listing
containing the names of all DTC participants reflected on DTC's books as
holding interests in the certificates on that record date. On each
distribution date, the applicable pass through trustee will mail to each DTC
participant holding certificates the statement described above and will make
available additional copies as requested by the DTC participants for
forwarding to certificateholders.

   After the end of each calendar year, each pass through trustee will prepare
for each person that was a holder of one or more of its pass through
certificates at any time during the preceding calendar year a report
containing the sum of the amount of distributions allocable to principal,
premium and interest with respect to that pass through trust for the preceding
calendar year or, in the event the person was a holder of a pass through
certificate during only a portion of the preceding calendar year, for the
applicable portion of the preceding calendar year. In addition, each pass
through trustee will prepare for each person that was a holder of one or more
of its pass through certificates at any time during the preceding calendar
year any other items that are readily available to the pass through trustee
and which a certificateholder reasonably requests as necessary for the purpose
of preparing its federal income tax returns. The reports and other items
described in this section will be prepared on the basis of information
supplied to the pass through trustee by DTC participants and will be delivered
by the pass through trustee to DTC participants to be available for forwarding
by DTC participants to certificateholders in the manner described above.

   If the certificates are issued in the form of physical certificates, the
pass through trustee of that pass through trust will prepare and deliver the
information described above to each record holder of a pass through
certificate issued by that pass through trust as the name and period of
ownership of the holder appears on the records of the registrar of the
certificates.

Voting of Secured Promissory Notes

   A pass through trustee has the right to vote and give consents and waivers
with respect to the secured promissory notes held by that pass through trust.
However, the pass through trustee's right to vote and give consents or waivers
may be restricted or may be exercisable by another person in accordance with
the terms of an intercreditor agreement, as described in the applicable
prospectus supplement. The pass through trust agreement will set forth:

  .  the circumstances in which a pass through trustee may direct any action
     or cast any vote with respect to the secured promissory notes held in
     its pass through trust at its own discretion;

  .  the circumstances in which a pass through trustee will seek instructions
     from its certificateholders; and

  .  if applicable, the percentage of certificateholders required to direct
     the pass through trustee to take action.

   If the holders of certificates are entitled to the benefits of a liquidity
facility, and the liquidity facility is used to make any payments to
certificateholders, the provider of the liquidity facility may be entitled to
exercise rights to vote or give consents and waivers with respect to the
secured promissory notes held by the pass through trust that issued the
certificates, as described in the applicable prospectus supplement.


                                      15
<PAGE>

Events of Default and Certain Rights upon an Event of Default

   The prospectus supplement will describe the events of default that can occur
under the pass through trust agreement and under the indentures relating to the
secured promissory notes held by the related pass through trust.

   Defaults under a leased aircraft indenture will include events of default
under the lease that we are a party to that is assigned as security under that
leased aircraft indenture. The owner trustee and the owner participant may have
rights to cure the defaults under a leased aircraft indenture that result from
a default under the lease. The applicable prospectus supplement will describe
these cure rights. Unless otherwise provided in a prospectus supplement, with
respect to any certificates entitled to the benefits of a liquidity facility, a
drawing under that liquidity facility for the purpose of making a payment of
interest as a result of our failure to have made a corresponding payment under
the lease will not cure a default related to our failure to make the payment.

   Unless otherwise provided in a prospectus supplement, all of the secured
promissory notes issued under the same indenture will relate to a specific
aircraft and there will be no cross-collateralization or cross-default
provisions in the indentures. This means that events resulting in a default
under a particular indenture will not necessarily result in a default under any
other indenture. If a default occurs in fewer than all of the indentures,
payments of principal of, and interest on, the secured promissory notes issued
under indentures with respect to which a default has not occurred will continue
to be made as originally scheduled.

   The pass through trustees, as holders of the secured promissory notes, may
enter into an intercreditor agreement that may have the practical effect of
subordinating a junior class of secured promissory notes issued under one
indenture to senior classes of secured promissory notes under other indentures.
This concept, referred to as cross-subordination, is described above under
"Description of the Certificates--General" and, if applicable, will be
described in the applicable prospectus supplement.

   If the secured promissory notes outstanding under an indenture are held by
more than one pass through trust, then the ability of the holders of
certificates issued by any one pass through trust to cause the loan trustee to
take actions under an indenture may be limited. In particular, a pass through
trustee's ability to direct a loan trustee to take action under an indenture
will depend, in part, on the proportion of (a) the aggregate principal amount
of the secured promissory notes outstanding under the indenture that are held
in that pass through trust to (b) the aggregate principal amount of all secured
promissory notes outstanding under the indenture. This means that a pass
through trustee may not have the ability to direct a loan trustee to accelerate
secured promissory notes or exercise remedies under an indenture without the
concurrence of the other pass through trustees. In addition, the ability of a
pass through trustee to exercise remedies under an indenture may be limited by
the terms of an intercreditor agreement.

   If the secured promissory notes outstanding under an indenture are held by
more than one pass through trust, then each pass through trust will hold
secured promissory notes with different terms than the secured promissory notes
held in the other pass through trusts. In these circumstances, the holders of
certificates issued by different pass through trusts may have divergent or
conflicting interests. As long as the same institution acts as the pass through
trustee of each pass through trust, in the absence of instructions from the
holders of certificates issued by each pass through trust, the pass through
trustee could for the same reason be faced with a potential conflict of
interest upon a default under an indenture. If the pass through trustee is
faced with a conflict of interest because that pass through trustee acts as
pass through trustee for multiple trusts, the pass through trustee faced with
the conflict will resign as trustee of one or all the pass through trusts, and
one or more successor pass through trustees will be appointed in accordance
with the terms of each pass through trust agreement.

   The prospectus supplement for a series of certificates will describe whether
and under what circumstances a pass through trustee may or will sell all or
part of the secured promissory notes held in the pass through trust. A pass
through trustee's right to sell secured promissory notes may be restricted or
may be exercisable by another person, if the applicable series of certificates
are subject to any intercreditor, subordination or similar

                                       16
<PAGE>

arrangements. If the certificates of any series are subject to any
intercreditor, subordination or similar arrangement, the proceeds from the sale
of the related secured promissory notes will be distributed as contemplated by
those arrangements. To the extent received by any pass through trustee,
proceeds from the sale of secured promissory notes will be treated as special
payments, deposited in a special payments accounts and distributed to the
certificateholders of the pass through trust on a special distribution date.

   The market for secured promissory notes in default may be very limited, and
neither we nor the pass through trustee can assure you that they could be sold
for a reasonable price. In addition, as long as the same institution acts as
pass through trustee of multiple pass through trusts, it may be faced with a
conflict in deciding which secured promissory notes to sell to available
buyers. If the pass through trustee sells any secured promissory notes with
respect to which a default under an indenture exists for less than their
outstanding principal amount, the certificateholders of that pass through trust
will receive a smaller amount of principal distributions than anticipated and
will not have any claim for the shortfall against us, our parent, any owner
trustee, any owner participant or any pass through trustee. Neither a pass
through trustee nor the holders of certificates will be able to take any action
with respect to any secured promissory notes unless a default has occurred
under the indenture relating to those secured promissory notes.

   Following a default under an indenture, all payments received by a pass
through trustee or with respect to secured promissory notes issued under the
indenture, other than scheduled payments received on or within five days of the
date the scheduled payments are due, will be treated as special payments and
deposited in a special payments account. All amounts deposited in the special
payments account will be distributed to the certificateholders on a special
distribution date. The rights of any pass through trustee to receive payments
made on or with respect to any secured promissory note following a default
under any indenture may be limited by intercreditor, subordination or similar
arrangements.

   Any funds held in the special payments account for a pass through trust
will, to the extent practicable, be invested and reinvested by the pass through
trustee in permitted short-term investments pending the distribution of those
funds on a special distribution date. Permitted investments will be specified
in the related prospectus supplement.

   The Basic Agreement provides that the pass through trustee of each pass
through trust will give to the certificateholders of that pass through trust
notice of all uncured or unwaived defaults known to it with respect to that
pass through trust. The Basic Agreement requires each pass through trustee to
provide the notice of default within 90 days after the occurrence of the
default. However, except in the case of default in the payment of principal,
premium, if any, or interest on any of the secured promissory notes held in a
pass through trust, the pass through trustee will be protected in withholding a
notice of default if it in good faith determines that withholding the notice is
in the interest of the certificateholders. The term "default" as used in this
paragraph means only the occurrence of a default under an indenture with
respect to secured promissory notes held in a pass through trust as described
above, except that in determining whether any default under an indenture has
occurred, any related grace period or notice will be disregarded.

   The Basic Agreement requires the pass through trustee to act with a
specified standard of care while a default is continuing under an indenture. In
addition, the Basic Agreement contains a provision entitling the pass through
trustee to be offered reasonable security or indemnification by the
certificateholders of the pass through trust before proceeding to exercise any
right or power under the Basic Agreement at the request of those
certificateholders.

   The prospectus supplement for a series of certificates will specify the
percentage of certificateholders entitled to waive, or to instruct the pass
through trustee to waive, any past default with respect to the related pass
through trust. The prospectus supplement for a series of certificates also will
specify the percentage of certificateholders entitled to waive, or to instruct
the pass through trustee or the loan trustee to waive, any past default, or
rescind or annul any direction given under any indenture.

Merger, Consolidation and Transfer of Assets

   We will be prohibited from consolidating with or merging into any other
corporation or transferring substantially all of our assets as an entirety to
any other corporation unless:

  .  the surviving, successor or transferee corporation:

    .  is validly existing under the laws of the United States or any of
       its states;

    .  is a citizen of the United States (as defined in Title 49 of the
       United States Code relating to aviation (the "Transportation Code"))
       holding an air carrier operating certificate issued by the Secretary
       of Transportation pursuant to Chapter 447 of Title 49, United States
       Code, if, and so long as, such status is a condition of entitlement
       to the benefits of Section 1110 of the Bankruptcy Code relating to
       the rights of creditors of an airline in the event of the airline's
       bankruptcy; and

    .  expressly assumes all of our obligations contained in the Basic
       Agreement and any supplement to the Basic Agreement, the note
       purchase agreement, any indentures, any participation agreements
       and, with respect to aircraft leased by us, the applicable leases;
       and

  .  we have delivered a certificate and an opinion or opinions of counsel
     indicating that the transaction, in effect, complies with these
     conditions.

Modifications of the Basic Agreement

   The Basic Agreement contains provisions permitting us, our parent and the
pass through trustee of each pass through trust to enter into a supplement to
the pass through trust agreement, without the consent of the holders of any of
the certificates issued by a pass through trust in order to do the following,
among others:

  .  to provide for the formation of a pass through trust and the issuance of
     a series of certificates and to set forth the terms of the certificates;

  .  to evidence the succession of another corporation or entity to us or our
     parent and the assumption by that corporation or entity of our or our
     parent's obligations under the pass through trust agreement;

  .  to add to our or our parent's covenants for the benefit of holders of
     certificates, or to surrender any right or power in the pass through
     trust agreement conferred upon us or our parent;

  .  to cure any ambiguity or correct or supplement any defective or
     inconsistent provision of the pass through trust agreement, so long as
     those changes will not materially adversely affect the interests of the
     holders of the certificates, or to cure any ambiguity or correct any
     mistake or, to give effect to or provide for replacement liquidity
     facilities, if applicable, to the certificates;

  .  to comply with any requirement of the SEC, any applicable law, rules or
     regulations of any exchange or quotation system on which any
     certificates may be listed or of any regulatory body;

  .  to modify, eliminate or add to the provisions of the pass through trust
     agreement to the extent necessary to continue the qualification of the
     pass through trust agreement under the Trust Indenture Act of 1939, and
     to add to the pass through trust agreement other provisions as may be
     expressly permitted by the Trust Indenture Act excluding, however, the
     provisions referred to in section 316(a)(2) of the Trust Indenture Act
     as in effect at the date of the Basic Agreement or any corresponding
     provision in any similar Federal statute enacted after that date;

  .  to provide for a successor pass through trustee or to add to or change
     any provision of the pass through trust agreement as necessary to
     facilitate the administration of the pass through trusts created under
     the pass through trust agreement by more than one pass through trustee;

  .  to provide certain information to the pass through trustee as required
     in the pass through trust agreement;

                                       18
<PAGE>

  .  to release our parent from the Basic Agreement, but only if our parent
     has not executed a guarantee in respect of any lease or secured
     promissory note; and

  .  to make any other amendments or modifications to the Basic Agreement so
     long as those amendments or modifications apply only to certificates of
     a series issued after the date of the amendment or modification.

   No supplement to the pass through trust agreement may be made that will
adversely affect the status of any pass through trust as a grantor trust for
United States federal income tax purposes, without the consent of the
certificateholders.

   The Basic Agreement also contains provisions permitting us, our parent and
the pass through trustee of each pass through trust, with the consent of a
majority in interest of the certificateholders of the pass through trust and,
with respect to any aircraft leased by us, with the consent of the applicable
owner trustee, which cannot be unreasonably withheld, to execute a supplement
to the pass through trust agreements adding any provisions to or changing or
eliminating any of the provisions of the Basic Agreement, to the extent
relating to that pass through trust, and the applicable pass through trust
supplement, or modifying the rights of the certificateholders, except that no
supplement may, without the consent of each affected certificateholder:

  .  reduce in any manner the amount of, or delay the timing of, any receipt
     by the pass through trustee of payments on the secured promissory notes
     held in the pass through trust or distributions in respect of any pass
     through certificate issued by the pass through trust, or change the date
     or place of any payment in respect of any pass through certificate, or
     make distributions payable in currency other than that provided for in
     the certificates, or impair the right of any certificateholder to
     institute suit for the enforcement of any payment when due;

  .  permit the disposition of any secured promissory note held in the pass
     through trust, except as provided in the pass through trust agreement,
     or otherwise deprive any certificateholder of the benefit of the
     ownership of the applicable secured promissory notes;

  .  reduce the percentage of the aggregate fractional undivided interests of
     the pass through trust provided for in the applicable supplement to the
     Basic Agreement that is required in order to obtain the consent of the
     holders for that supplement or for any waiver provided for in the Basic
     Agreement or the supplement;

  .  modify any of the provisions relating to the rights of the
     certificateholders in respect of the waiver of events of default or
     receipt of payment except to increase any such percentage or to provide
     that certain other provisions of the Basic Agreement and any applicable
     supplement cannot be waived or modified without the consent of all
     applicable certificateholders;

  .  alter the priority of distributions described in any applicable
     intercreditor agreement, in a manner materially adverse to the interests
     of the certificateholders of the pass through trust; or

  .  adversely affect the status of any pass through trust as a grantor trust
     for United States federal income tax purposes.

Modification of Indenture and Related Agreements

   The prospectus supplement will specify the pass through trustee's
obligations in the event that a pass through trustee, as the holder of any
secured promissory notes held in a pass through trust, receives a request for
its consent to any amendment, modification or waiver under the indenture under
which the secured promissory notes were issued, under the lease relating to the
aircraft leased by us that was financed with the proceeds of the secured
promissory notes, under any liquidity facility or under other documents
relating to the secured promissory notes.

                                       19
<PAGE>

Cross-Subordination Issues

   The secured promissory notes issued under an indenture may be held in more
than one pass through trust, and one pass through trust may hold secured
promissory notes issued under more than one indenture. Unless otherwise
provided in a prospectus supplement, only secured promissory notes of the same
class may be held in the same pass through trust. In this event, payments made
on account of a junior class of certificates issued under a prospectus
supplement may, under circumstances described in the prospectus supplement, be
subordinated to the prior payment of all amounts owing to certificateholders of
a pass through trust that holds a senior class of secured promissory notes
issued under any indenture. The prospectus supplement related to an issuance of
certificates will describe any cross-subordination provisions and any related
terms, including the percentage of certificateholders under any pass through
trust that is permitted to:

  .  grant waivers of defaults under any indenture under which secured
     promissory notes held by that pass through trust were issued;

  .  consent to the amendment or modification of any indenture under which
     secured promissory notes held by that pass through trust were issued; or

  .  direct the exercise of remedial actions under any indenture under which
     secured promissory notes held by that pass through trust were issued.

Termination of the Pass Through Trusts

   The obligations of the parties to each pass through trust agreement will
terminate upon the distribution to certificateholders of that pass through
trust of all amounts required to be distributed to them under the pass through
trust agreement. The pass through trustee will send to each certificateholder
of record of the pass through trust notice of the termination of that pass
through trust, the amount of the proposed final payment and the proposed date
for the distribution of the final payment for that pass through trust. The
final distribution to any certificateholder will be made only upon surrender of
the certificateholder's certificates at the office or agency of the pass
through trustee, paying agent or transfer agent, as specified in the notice of
termination.

Delayed Purchase of Secured Promissory Notes

   If all of the proceeds from the sale of the certificates are not used on the
date the certificates are issued to purchase the secured promissory notes
contemplated to be held in the pass through trust that issued those
certificates, the secured promissory notes may be purchased by the pass through
trustee at any time on or prior to the date specified in the applicable
prospectus supplement. In this event, the portion of the proceeds from the sale
of the certificates that are not used to purchase secured promissory notes on
the date the certificates are issued will be held under an arrangement
described in the applicable prospectus supplement pending the purchase of the
secured promissory notes. The arrangements with respect to the payment of
interest on funds held pending purchase of secured promissory notes will also
be described in the applicable prospectus supplement. If any proceeds are not
subsequently used to purchase secured promissory notes by the final date for
purchase of secured promissory notes specified in the applicable prospectus
supplement, the proceeds will be returned to the holders of the certificates.

Liquidity Facility and Other Credit Enhancements

   A prospectus supplement may provide that one or more payments of interest to
be paid with respect to the certificates of one or more series will be
supported by a liquidity facility issued by an institution identified in the
related prospectus supplement. The provider of a liquidity facility for the
holders of a series of certificates may have a claim on property of the pass
through trust senior to the claims of the holders of the certificates of that
series as described in the related prospectus supplement. The prospectus
supplement will also specify the circumstances under which a liquidity provider
will be entitled to direct the exercise of remedies under any indenture. The
prospectus supplement will also describe any other credit enhancements, if any,
that may apply to the certificates.

                                       20
<PAGE>

The Pass Through Trustee

   Unless otherwise provided in the prospectus supplement for any series of
certificates, the pass through trustee for each series of certificates will be
State Street Bank and Trust Company of Connecticut, National Association. With
certain exceptions as to itself in its individual capacity, the pass through
trustee makes no representations as to the validity or sufficiency of the Basic
Agreement, the pass through trust supplements, the certificates, the secured
promissory notes, the indentures, the leases or other related documents. The
pass through trustee will not be liable with respect to any series of
certificates for any action taken or omitted to be taken by it in good faith in
accordance with the direction of the holders of a majority in face amount of
outstanding certificates of that series issued under the Basic Agreement.
Subject to those provisions, the pass through trustee will be under no
obligation to exercise any of its rights or powers under the Basic Agreement at
the request of any holders of certificates issued under the Basic Agreement
unless they have offered to the pass through trustee indemnity satisfactory to
it. The Basic Agreement provides that the pass through trustee in its
individual or any other capacity may acquire and hold certificates issued under
the Basic Agreement and may, in accordance with the Basic Agreement, otherwise
deal with us and, with respect to the aircraft leased by us, any owner trustee
with the same rights it would have if it were not the pass through trustee.

   The pass through trustee may resign with respect to any or all of the pass
through trusts at any time, in which event we will be obligated to appoint a
successor pass through trustee. If the pass through trustee ceases to be
eligible to continue as pass through trustee with respect to a pass through
trust or becomes incapable of acting as pass through trustee or becomes
insolvent, we may remove that pass through trustee, or any certificateholder of
the applicable pass through trust for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the pass through trustee and the appointment of
a successor pass through trustee. Any resignation or removal of the pass
through trustee with respect to a pass through trust and appointment of a
successor pass through trustee for the pass through trust does not become
effective until acceptance of the appointment by the successor pass through
trustee. Under these resignation and successor pass through trustee provisions,
it is possible that a different pass through trustee could be appointed to act
as the successor pass through trustee with respect to each pass through trust.
All references in this prospectus to the pass through trustee should be read to
take into account the possibility that the pass through trusts could have
different successor pass through trustees in the event of a resignation or
removal.

   The Basic Agreement provides that we will pay the pass through trustee's
fees and expenses and indemnify the pass through trustee against certain
liabilities.

Book-Entry Registration

 General

   Unless otherwise specified in the applicable prospectus supplement, the
certificates will be subject to the procedures and provisions described below.

   Upon issuance, each series of certificates will be represented by one or
more fully registered global certificates. This means that one physical
certificate or a number of physical certificates representing all of the
certificates will be registered with the Depository Trust Company ("DTC"). Each
global certificate will be deposited with, or on behalf of, DTC and registered
in the name of Cede & Co. ("Cede"), the nominee of DTC. Certificateholders will
not be entitled to receive a physical certificate representing an interest in
its certificates, except as set forth below under "--Physical Certificates".
Unless and until physical certificates are issued under the limited
circumstances described below, all references in this prospectus and any
prospectus supplement to actions by certificateholders will refer to actions
taken by DTC upon instructions from DTC participants, and all references to
distributions, notices, reports and statements to certificateholders will
refer, as the case may be, to distributions, notices, reports and statements to
DTC or Cede, as the registered holder of the certificates, or to DTC
participants for distribution to certificateholders in accordance with DTC
procedures.

                                       21
<PAGE>

   DTC has advised us that DTC is a limited purpose trust company organized
under the laws of the State of New York, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code and "clearing agency" registered pursuant to Section 17A of the
Securities Exchange Act of 1934.

   Under the New York Uniform Commercial Code, a "clearing corporation" is
defined as:

  .  a person that is registered as a "clearing agency" under the federal
     securities laws;

  .  a federal reserve bank; or

  .  any other person that provides clearance or settlement services with
     respect to financial assets that would require it to register as a
     clearing agency under the federal securities laws but for an exclusion
     or exemption from the registration requirement, if its activities as a
     clearing corporation, including promulgation of rules, are subject to
     regulation by a federal or state governmental authority.

   A "clearing agency" is an organization established for the execution of
trades by transferring funds, assigning deliveries and guaranteeing the
performance of the obligations of parties to trades.

   DTC was created to hold securities for its participants and to facilitate
the clearance and settlement of securities transactions between DTC
participants through electronic book-entry changes in the accounts of DTC
participants. The ability to execute transactions through book-entry changes in
accounts eliminates the need for transfer of physical certificates. DTC
participants include securities brokers and dealers, banks, trust companies,
clearing corporations and certain other organizations. DTC is owned by a number
of DTC participants and by the New York Stock Exchange, the American Stock
Exchange, and the National Association of Securities Dealers. Banks, brokers,
dealers, trust companies and other entities that clear through or maintain a
custodial relationship with a DTC participant either directly or indirectly
have indirect access to the DTC system.

   Under the rules, regulations and procedures creating and affecting DTC and
its operations, DTC is required to make book-entry transfers of the
certificates among DTC participants on whose behalf it acts with respect to the
certificates and to receive and transmit distributions of principal, premium,
if any, and interest with respect to the certificates. DTC participants and
indirect DTC participants with which certificateholders have accounts similarly
are required to make book-entry transfers and receive and transmit such
payments on behalf of their respective customers. Certificateholders that are
not DTC participants or indirect DTC participants but desire to purchase, sell
or otherwise transfer ownership of, or other interests in, the certificates may
do so only through DTC participants and indirect DTC participants. In addition,
certificateholders will receive all distributions of principal, premium, if
any, and interest from the pass through trustee through DTC participants or
indirect DTC participants, as the case may be. Under a book-entry format,
certificateholders may experience some delay in their receipt of payments
because payments with respect to the certificates will be forwarded by the pass
through trustee to Cede, as nominee for DTC. We expect DTC to forward payments
in same-day funds to each DTC participant who is credited with ownership of the
certificates in an amount proportionate to the principal amount of that DTC
participant's holdings of beneficial interests in the certificates, as shown on
the records of DTC or its nominee. We also expect that DTC participants will
forward payments to indirect DTC participants or certificateholders, as the
case may be, in accordance with standing instructions and customary industry
practices. DTC participants will be responsible for forwarding distributions to
certificateholders. Accordingly, although certificateholders will not possess
physical certificates, DTC's rules provide a mechanism by which
certificateholders will receive payments on the certificates and will be able
to transfer their interests.

   Unless and until physical certificates are issued under the limited
circumstances described below, the only physical certificateholder will be
Cede, as nominee of DTC. Certificateholders will not be recognized by the pass
through trustee as registered owners of certificates under the pass through
trust agreement. Certificateholders will be permitted to exercise the rights
under the pass through trust agreement only indirectly through DTC and DTC
participants. DTC has advised us that it will take any action permitted to be
taken by a

                                       22
<PAGE>

certificateholder under the pass through trust agreement only at the direction
of one or more DTC participants to whose accounts with DTC the certificates are
credited. Additionally, DTC has advised us that in the event any action
requires approval by certificateholders of a certain percentage of the
beneficial interests in a pass through trust, DTC will take such action only at
the direction of and on behalf of DTC participants whose holdings include
undivided interests that satisfy any such percentage. DTC may take conflicting
actions with respect to other undivided interests to the extent that such
actions are taken on behalf of DTC participants whose holdings include those
undivided interests. DTC will convey notices and other communications to DTC
participants, and DTC participants will convey notices and other communications
to indirect DTC participants and to certificateholders in accordance with
arrangements among them. Arrangements among DTC and its direct and indirect
participants are subject to any statutory or regulatory requirements as may be
in effect from time to time. DTC's rules applicable to itself and DTC
participants are on file with the SEC.

   A certificateholder's ability to pledge the certificates to persons or
entities that do not participate in the DTC system, or otherwise to act with
respect to such certificates may be limited due to the lack of a physical
certificate to evidence ownership of the certificates and because DTC can only
act on behalf of DTC participants, who in turn act on behalf of indirect DTC
participants.

   None of us, our parent or the pass through trustees will have any liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests in the certificates held by Cede, as nominee for
DTC, for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests or for the performance by DTC, any DTC
participant or any indirect DTC participant of their respective obligations
under the rules and procedures governing their obligations.

   The applicable prospectus supplement will specify any additional book-entry
registration procedures applicable to certificates denominated in a currency
other than United States dollars.

   The information contained in this prospectus concerning DTC and its book
entry system has been obtained from sources we believe to be reliable, but we
take no responsibility for the accuracy thereof.

 Same-Day Settlement and Payment

   As long as the certificates are registered in the name of DTC or its
nominee, we will make all payments under any lease or any owned aircraft
indenture in immediately available funds. The pass through trustees will pass
through to DTC all payments received from us, including the final distribution
of principal with respect to the certificates of any pass through trust in
immediately available funds.

   Any certificates registered in the name of DTC or its nominee will trade in
DTC's Same-Day Funds Settlement System until maturity. DTC will require
secondary market trading activity in the certificates to settle in immediately
available funds. We cannot give any assurance as to the effect, if any, of
settlement in same-day funds on trading activity in the certificates.

 Physical Certificates

   Physical certificates will be issued in paper form to certificateholders or
their nominees, rather than to DTC or its nominee, only if:

  .  we advise a pass through trustee in writing that DTC is no longer
     willing or able to discharge properly its responsibilities as depository
     with respect to the certificates and we or the pass through trustee is
     unable to locate a qualified successor;

  .  we elect to terminate the book-entry system through DTC; or

  .  after the occurrence of certain events of default or other events
     specified in the related prospectus supplement, certificateholders
     owning at least a majority in interest in a pass through trust advise
     the applicable pass through trustee, us and DTC through DTC participants
     that the continuation of a book-entry system through DTC participants is
     no longer in the certificateholders' best interest.

                                       23
<PAGE>

   If physical certificates are to be issued by a pass through trust, the
applicable pass through trustee will notify all certificateholders through DTC
of the availability of physical certificates. Upon surrender by DTC of
certificates representing the global physical certificates and receipt of
instructions for re-registration, the pass through trustee will reissue the
certificates as physical certificates to certificateholders.

   After physical certificates are issued, the pass through trustee or a paying
agent will make distributions of principal, premium, if any, and interest with
respect to certificates directly to holders in whose names the physical
certificates were registered at the close of business on the applicable record
date. Except for the final payment to be made with respect to a certificate,
the pass through trustee or a paying agent will make distributions by check
mailed to the addresses of the registered holders as they appear on the
register maintained by the pass through trustee. The pass through trustee or a
paying agent will make the final payment with respect to any pass through
certificate only upon presentation and surrender of the applicable pass through
certificate at the office or agency specified in the notice of final
distribution to certificateholders.

   Physical certificates will be freely transferable and exchangeable at the
office of the pass through trustee upon compliance with the requirements set
forth in the pass through trust agreement. Neither the pass through trustee nor
any transfer or exchange agent will impose a service charge for any
registration of transfer or exchange. However, the pass through trustee or
transfer or exchange agent will require payment of a sum sufficient to cover
any tax or other governmental charge.

                  DESCRIPTION OF THE SECURED PROMISSORY NOTES

   The statements made under this caption are summaries of terms that we expect
will be common to all secured promissory notes. Where no distinction is made
between the leased aircraft notes and the owned aircraft notes or between their
respective indentures, the statements refer to all secured promissory notes and
all indentures. Most of the financial and other specific terms of any series of
secured promissory notes will be described in a prospectus supplement to be
attached to this prospectus. Since the terms of the secured promissory notes
may differ from the general information provided below, you should rely on the
information in the prospectus supplement instead of the information in this
prospectus if the information in the prospectus supplement is different from
the information below.

   The following information is a summary and does not describe every aspect of
the secured promissory notes. The summary is subject to all the provisions of
the applicable secured promissory notes, indentures, leases, note purchase
agreements, pass through trust agreements, participation agreements,
intercreditor and subordination agreements, liquidity facilities and other
agreements and arrangements relating to any series of secured promissory notes.

   Additional provisions with respect to the secured promissory notes and the
associated aircraft financing transactions will be described in the applicable
prospectus supplement. To the extent that any provision in any prospectus
supplement is inconsistent with any provisions in this summary, the provision
of the prospectus supplement will control.

General

   The secured promissory notes will be issued under indentures. Promissory
notes secured by an aircraft that is leased to us will be non-recourse and will
be issued under an indenture between an owner trustee and a loan trustee.
Promissory notes secured by an aircraft that is owned by us will be recourse to
us and will be issued under an indenture between a loan trustee and us.

   The leased aircraft notes will be non-recourse obligations of the applicable
owner trustee. All of the leased aircraft notes issued under the same indenture
will relate to and will be secured by one or more specific aircraft leased to
us. Unless otherwise specified in the applicable prospectus supplement, leased
aircraft notes will not be secured by any other aircraft.


                                       24
<PAGE>

   We will be the issuer of owned aircraft notes. The owned aircraft notes will
be our direct recourse obligations. All of the owned aircraft notes issued
under the same indenture will relate to, and will be secured by, one or more
specific aircraft that we own. Unless otherwise specified in the applicable
prospectus supplement, the owned aircraft notes will not be secured by any
other aircraft.

   If specified in a prospectus supplement, we will have the right (a) to
arrange a sale and leaseback of one or more aircraft that we own referred to in
the prospectus supplement and the assumption, on a non-recourse basis, of the
related owned aircraft notes by an owner trustee or (b) to substitute other
aircraft, cash or U.S. government securities or a combination thereof in place
of the aircraft that we own securing the related owned aircraft notes. The
terms and conditions of any sale and leaseback or aircraft substitution will be
described in the applicable prospectus supplement.

   If specified in a prospectus supplement, one of our affiliates may act as an
owner participant in a leveraged lease transaction. If one of our affiliates
acts as owner participant, it may transfer its interest in the owner trust to a
third party at any time during the term of the lease. In connection with that
transfer, the lease and other documents may be amended and the secured
promissory notes issued under the applicable indenture may be amended or
refinanced.

Principal and Interest Payments

   The secured promissory notes will bear interest at the rates set forth in
the applicable indenture. We expect that the rates set forth in the applicable
indenture for each series of secured promissory notes will be the same rate as
the annual rate for the certificates issued by the pass through trust that
purchases that series of secured promissory notes. Interest on the secured
promissory notes will be payable by the issuer of those secured promissory
notes on each day that is a regular distribution date for the certificates
issued by the pass through trust that purchases those secured promissory notes.

   The issuer of any series of secured promissory notes will repay principal in
accordance with the schedule set forth in the applicable prospectus supplement.
The principal amortization schedule for each individual aircraft financing will
vary to reflect the economic terms of the individual financing.

   If any date scheduled for any payment of principal, premium, if any, or
interest with respect to a secured promissory note is not a business day, the
payment will be made on the next succeeding business day without any additional
interest, unless otherwise provided in the applicable prospectus supplement.

Redemption

   The applicable prospectus supplement will describe the circumstances under
which the secured promissory notes may be redeemed or purchased prior to their
stated maturity date, in whole or in part. In addition, the prospectus
supplement will describe the premium, if any, applicable upon redemptions or
purchases and other terms applying to the redemptions or purchases of the
secured promissory notes.

Security

   The leased aircraft notes will be secured by:

  .  an assignment by the related owner trustee to the related loan trustee
     of that owner trustee's rights, except for certain rights described
     below, under the lease or leases or other agreements with respect to the
     related aircraft leased by us, including the right to receive payments
     of rent under the applicable lease; and

  .  a mortgage granted to the related loan trustee in the aircraft financed
     by the issue of those leased aircraft notes, subject to our rights under
     the lease or leases relating to that aircraft and other property rights,
     if any, described in the applicable prospectus supplement.


                                       25
<PAGE>

   With respect to the leased aircraft, the assignment by the related owner
trustee to the related loan trustee of its rights under the related lease will
exclude, among other things:

  .  rights of the owner trustee and the related owner participant to
     indemnification by us for certain matters;

  .  insurance proceeds payable to the owner trustee in its individual
     capacity and to the owner participant under liability insurance that we
     maintain pursuant to the lease or that the owner trustee or the owner
     participant maintains;

  .  insurance proceeds payable to the owner trustee or to the owner
     participant under certain casualty insurance maintained by the owner
     trustee or the owner participant pursuant to the lease; and

  .  any rights of the owner participant or the owner trustee to enforce
     payment of the foregoing amounts and their respective rights to the
     proceeds of the foregoing indemnification and insurance.

   In addition, the assignment will be limited to provide that, unless and
until a default occurs and is continuing under an indenture with respect to a
leased aircraft, the related loan trustee may exercise only limited rights of
the related owner trustee under the related lease.

   All of the leases will be net leases. Under a net lease, we are obligated,
among other things and at our expense, to cause each aircraft leased by us to
be duly registered, to pay all costs of operating the aircraft and to maintain,
service, repair and overhaul, or cause to be maintained, serviced, repaired and
overhauled, the aircraft.

   Unless otherwise specified in the applicable prospectus supplement, the
secured promissory notes will not be cross-collateralized and consequently the
secured promissory notes issued in respect of any one aircraft will not be
secured by any other aircraft or, in the case of leased aircraft notes, the
lease related to any other aircraft.

   The owned aircraft notes will be secured by a mortgage granted to the
related loan trustee of all of our right, title and interest in and to the
applicable aircraft owned by us. Under the terms of each owned aircraft
indenture, we will be obligated, among other things and at our expense, to
cause each owned aircraft to be duly registered, to pay all costs of operating
the aircraft and to maintain, service, repair and overhaul, or cause to be
maintained, serviced, repaired or overhaul, the aircraft.

   The prospectus supplement will describe the required insurance coverage with
respect to the aircraft financed with the proceeds from the pass through
certificates issued.

   Except in certain circumstances, we will keep each aircraft registered under
the Transportation Code. In addition, we will record the indentures, the leases
and other documents necessary for a valid conveyance of an interest in the
aircraft under the Transportation Code. Each indenture will be effective to
create a valid security interest in the aircraft that is subject to that
indenture. When that indenture and other appropriate documents are filed with
the FAA in accordance with the Transportation Code and uniform commercial code
financing statements are filed in all appropriate jurisdictions, the loan
trustee will have a perfected security interest in the related aircraft
whenever it is located in the United States or any of its territories and
possessions.

   The Convention on the International Recognition of Rights in aircraft (the
"Convention") provides that this security interest will also be recognized,
with certain limited exceptions, in those jurisdictions that have ratified or
adhere to the Convention. We will have the right, subject to certain
conditions, at our own expense to register each aircraft in countries other
than the United States. Each aircraft may also be operated by us or under
lease, sublease or interchange arrangements in countries that are not parties
to the Convention. The extent to which the related loan trustee's security
interest would be recognized in an aircraft located in a country that is not a
party to the Convention, and the extent to which such security interest would
be recognized in a jurisdiction adhering to the Convention if the aircraft is
registered in a jurisdiction not a party

                                       26
<PAGE>

to the Convention, is uncertain. Moreover, in the case of a default under an
indenture, the ability of the related loan trustee to realize upon its security
interest in an aircraft could be adversely affected as a legal or practical
matter if such aircraft is registered or located outside the United States.

   The loan trustee will invest and reinvest funds, if any, held by it from
time to time under an indenture. The loan trustee will, at our direction,
invest and reinvest funds, in certain investments described in the applicable
indenture. We will not be entitled to direct the loan trustee to invest and
reinvest funds with respect to a leased aircraft, in the case of a default
under the applicable lease or, with respect to an owned aircraft, in the case
of a default under the applicable indenture. We will pay the net amount of any
loss resulting from these investments.

   Section 1110 of the U.S. Bankruptcy Code provides in relevant part that,
unless certain events occur after the commencement of a Chapter 11 case, the
right of lessors, conditional vendors and holders of security interests with
respect to equipment (as defined in Section 1110 of the U.S. Bankruptcy Code
and described below) to take possession of such equipment in compliance with
the provisions of a lease, conditional sale contract or security agreement, as
the case may be, is not affected by:

  .  the automatic stay provision of the U.S. Bankruptcy Code, which
     provision prevents repossessions by creditors for the duration of the
     reorganization period;

  .  the provision of the U.S. Bankruptcy Code allowing the trustee in
     reorganization to use property of the debtor during the reorganization
     period;

  .  Section 1129 of the U.S. Bankruptcy Code (which governs the confirmation
     of plans of reorganization in Chapter 11 cases); or

  .  any power of the bankruptcy court to prevent a repossession.

   Specifically, Section 1110 provides in relevant part that the right of a
lessor, conditional vendor or holder of a security interest to take possession
of an aircraft upon an event of default may not be exercised for 60 days
following the date of commencement of the reorganization proceedings (unless
specifically permitted by the bankruptcy court) and may not be exercised at all
if, within such 60-day period (or such longer period consented to by the
lessor, conditional vendor or holder of a security interest), the trustee in
reorganization agrees to perform the debtor's obligations that become due on or
after such date and cures all existing defaults (other than defaults resulting
solely from the financial condition, bankruptcy, insolvency or reorganization
of the debtor). "Equipment" is defined in Section 1110 of the U.S. Bankruptcy
Code, in part, as an aircraft, aircraft engine, propeller, appliance, or spare
part (as defined in Section 40102 of Title 49 of the U.S. Code) that is subject
to a security interest granted by, leased to, or conditionally sold to a debtor
that is a citizen of the United States (as defined in Section 40102 of Title 49
of the U.S. Code) holding an air carrier operating certificate issued by the
Secretary of Transportation pursuant to chapter 447 of Title 49 of the U.S.
Code for aircraft capable of carrying 10 or more individuals or 6,000 pounds or
more of cargo (subject to certain limitations in the case of equipment first
placed in service on or prior to October 22, 1994).

   It will be a condition to the pass through trustee's obligation to purchase
secured promissory notes with respect to each aircraft that our outside counsel
provide its opinion to the pass through trustee that (a) if the aircraft is a
leased aircraft, the owner trustee, as lessor under the lease for that
aircraft, and the loan trustee, as assignee of such owner trustee's rights
under the lease pursuant to the applicable indenture, will be entitled to the
benefits of Section 1110 of the U.S. Bankruptcy Code with respect to the
airframe and engines comprising that aircraft or (b) if that aircraft is an
owned aircraft, the loan trustee will be entitled to the benefits of Section
1110 with respect to the airframe and engines comprising such owned aircraft,
in each case as long as we continue to be a citizen of the United States as
defined in Section 40102 of Title 49 of the U.S. Code holding an air carrier
operating certificate issued by the Secretary of Transportation pursuant to
Chapter 447 of Title 49 of the U.S. Code for aircraft capable of carrying 10 or
more individuals or 6,000 pounds or more of cargo. This Section 1110 opinion
will not address the possible replacement of an aircraft after an "Event of
Loss", as defined in the applicable indenture, in the future.

Ranking of Secured Promissory Notes

   Some of the secured promissory notes related to one or more aircraft may be
subordinated and junior in right of payment to other secured promissory notes
related to the same aircraft. The terms of any subordination will be described
in the related prospectus supplement.

Payments Under Leases and Limitation of Liability

   We will lease each leased aircraft from an owner trustee for a term
commencing on the delivery date of the aircraft to the owner trustee and
expiring no earlier than the latest maturity date of the related leased
aircraft notes, unless previously terminated as permitted by the terms of the
related lease. We will make basic rent and other payments under each lease and
the related documents to an owner trustee, as lessor. The owner trustee will
assign all payments of basic rent and certain other payments to the related
loan trustee. The loan trustee will, on behalf of the owner trustee, apply the
funds assigned to it under the related indenture to pay scheduled principal of,
premium, if any, and interest due from such owner trustee on the leased
aircraft notes issued under the related indenture. The balance of any basic
rent or other assigned amount under each lease and related documents, after
payment of amounts due on the leased aircraft notes issued under the related
indenture, will be paid over to the applicable owner trustee. In certain cases,
the basic rent and other payments under a lease may be adjusted, but each lease
will provide that under no circumstances will total payments by us be less than
the scheduled payments on the related leased aircraft notes. In some cases, an
owner participant may be required to make payments to an owner trustee that are
to be used by the owner trustee to pay principal of, and interest on, the
secured promissory notes. If an owner participant is required to make payments
to be used by an owner trustee to pay principal of, and interest on, the
secured promissory notes and the owner participant fails to make the payment,
we will be required to provide the owner trustee with funds sufficient to make
the payment. Our obligations to pay rent and to cause other payments to be made
under each lease and related documents will be general unsecured obligations.

   Except in circumstances in which we purchase a leased aircraft and assume
the related leased aircraft notes, the leased aircraft notes will not be
obligations of, or guaranteed by, us or our parent. None of the owner trustees,
the owner participants or the loan trustees will be personally liable to any
holder of leased aircraft notes for amounts payable under the leased aircraft
notes. Except as provided in the indentures relating to the leased aircraft
notes, no owner trustee or loan trustee will be liable or incur any liability
under the indentures. Except when we have assumed any leased aircraft notes and
except when an owner participant provides funds to be used by an owner trustee
to pay principal of, or interest on, the secured promissory notes, all amounts
payable under any leased aircraft notes will be made only from:

  .  the assets subject to the lien of the applicable indenture with respect
     to the aircraft or the income and proceeds received by the related loan
     trustee from that aircraft (including assigned rent payable by us under
     the related lease);

  .  if so provided in the related prospectus supplement, the applicable
     liquidity facility; or

  .  payments made in connection with optional redemptions or purchases by
     the related owner trustee or the related owner participant.

If an owner participant is required to make payments to be used by an owner
trustee to pay principal of, and interest on, the secured promissory notes and
the owner participant fails to make the payment, we will be required to provide
the owner trustee with funds sufficient to make the payment.

   Except as otherwise provided in the applicable indenture, no owner trustee
will be personally liable for any amount payable or for any statements,
representations, warranties, agreements or obligations under any indenture or
under any leased aircraft notes except for its own willful misconduct or gross
negligence. In general, none of the owner participants will have any duty or
responsibility under the leased aircraft indentures or under the leased
aircraft notes.

   Our obligations under each owned aircraft indenture and under the owned
aircraft notes will be secured obligations.

                                       28

Defeasance of the Indentures and the Secured Promissory Notes in Certain
Circumstances

   Unless otherwise specified in the applicable prospectus supplement, an
indenture may provide that the obligations of the related loan trustee, the
related owner trustee or us, as the case may be, under that indenture will be
deemed to have been discharged and paid in full on the 91st day after the date
that money or certain United States government securities, in an aggregate
amount sufficient to pay when due (including as a consequence of redemption in
respect of which notice is given on or prior to the date of such deposit)
principal, premium and interest with respect to all secured promissory notes
issued under that indenture, are irrevocably deposited with the related loan
trustee. The discharge may occur only if, among other things, there has been
published by the IRS a ruling or regulation to the effect that holders of the
secured promissory notes will not recognize income, gain or loss for federal
income tax purposes as a result of the deposit, defeasance and discharge and
will be subject to federal income tax on the same amount and in the same manner
and at the same time as would have been the case if the deposit, defeasance and
discharge had not occurred. Certain obligations, including the obligations to
register the transfer or exchange of secured promissory notes, to replace
stolen, lost, destroyed or mutilated secured promissory notes and to maintain
paying agencies and hold money for payment in trust may not be defeased.

   Upon defeasance of the secured promissory notes, or upon payment in full of
the principal of, premium, if any, and interest on all secured promissory notes
issued under any indenture on the applicable maturity date, or upon deposit
with the applicable loan trustee of sufficient money no earlier than one year
prior to the date of such maturity, the holders of the secured promissory notes
will have no beneficial interest in or other rights with respect to the related
aircraft or other assets subject to this lien of the indenture and the lien
will terminate.

Assumption of Obligations by US Airways

   Unless otherwise specified in the applicable prospectus supplement, upon our
purchase of any leased aircraft prior to the end of the applicable term, we may
assume on a full recourse basis all of the obligations of the owner trustee,
other than its obligations in its individual capacity, under the indenture and
the leased aircraft notes relating to that lease. If we assume leased aircraft
notes, provisions relating to maintenance, possession and use of the related
aircraft, liens and insurance will be incorporated into the indenture. If we
assume leased aircraft notes in connection with our purchase of a leased
aircraft, leased aircraft notes issued under the indenture will not be redeemed
and will continue to be secured by the aircraft. We may not assume leased
aircraft notes unless, among other things, we have provided an opinion of
counsel to the effect that:

  .  the loan trustee will be entitled to the benefits of Section 1110 of the
     U.S. Bankruptcy Code, except that the opinion need only be given if,
     immediately prior to the assumption, the owner trustee would have been
     entitled to the benefits of Section 1110; and

  .  holders of the secured promissory notes being assumed will not recognize
     income, gain or loss for federal income tax purposes as a result of the
     assumption and will be subject to federal income tax on the same amount
     and in the same manner and at the same time as would have been the case
     if the assumption had not occurred.

Parent Guarantee

   Our parent may guarantee the full and prompt payment of any or all amounts
payable or provided by us under the leases and other agreements related to a
series of certificates and the full and prompt payment by us of principal of,
premium, if any, and interest on owned aircraft notes related to a series of
certificates. Any guarantee will be described in the prospectus supplement
relating to the series of certificates issued by a pass through trust that owns
the leased aircraft notes or owned aircraft notes and will indirectly or
directly benefit from this guarantee. Unless otherwise stated in the applicable
prospectus supplement, we anticipate that this guarantee:

  .  will be unconditional;

  .  will be enforceable without any need first to enforce any lease or owned
     aircraft note against us; and

  .  will be an unsecured obligation of our parent.


                                       29
<PAGE>

Intercreditor Issues

   Secured promissory notes may be issued in different classes, which means
that the secured promissory notes may have different payment priorities even
though they are issued by the same borrower, relate to the same aircraft and
are issued under the same indenture. If multiple classes of secured promissory
notes are issued, the related prospectus supplement will describe the priority
of distributions among the secured promissory notes, the ability of any class
to exercise and/or enforce any or all remedies with respect to the related
aircraft, and, if the secured promissory notes are leased aircraft notes, the
related lease, and other intercreditor terms and provisions.

Owner Participant; Revisions to Agreements

   If specified in the applicable prospectus supplement, at the time
certificates are issued, we may still be seeking owner participants to invest
in certain leveraged lease transactions for the aircraft. The prospective owner
participants may request revisions to the forms of participation agreement,
lease, trust agreement and indenture so that the terms of the agreements
applicable to these aircraft may differ from the description of the agreements
contained in the applicable prospectus supplement.

   The terms of those agreements, however, will be required to:

  .  contain certain mandatory document terms; or

  .  not vary certain mandatory economic terms.

   In addition, we will be obligated:

  .  to certify to the pass through trustee that the modifications will not
     materially and adversely affect the certificateholders; and

  .  if the forms of documents are modified in any material respect that is
     adverse to the certificateholders, to obtain written confirmation from
     each rating agency that the use of modified versions of such agreements
     will not result in a withdrawal, suspension or downgrading of the rating
     of any class of certificates.

                            U.S. INCOME TAX MATTERS

General

   The following summary describes the material U.S. federal income tax
consequences to certificateholders of the purchase, ownership and disposition
of the certificates offered by this prospectus and in the opinion of Skadden,
Arps, Slate, Meagher & Flom LLP, tax counsel to US Airways, is accurate in all
material respects with respect to the matters discussed in this prospectus.
Except as otherwise specified, the summary is addressed to the initial
beneficial owners of certificates that are citizens or residents of the United
States, corporations, partnerships or other entities created or organized in or
under the laws of the United States or any state therein, or estates, the
income of which is subject to U.S. federal income taxation regardless of its
source, or trusts if a court within the U.S. is able to exercise primary
jurisdiction over the administration of the trust and one or more U.S. persons
have the authority to control all substantial decisions of the trust that will
hold the certificates as capital assets. This summary does not address the tax
treatment of U.S. certificateholders that may be subject to special tax rules,
for example, banks or insurance companies, nor does it address the tax
treatment of U.S. certificateholders that do not acquire certificates at the
initial offering price as part of the initial offering. This summary is not a
comprehensive description of all of the tax considerations that may be relevant
to a decision to purchase certificates. It does not describe any tax
consequences arising under the laws of any state, locality or taxing
jurisdiction other than the United States.

   The summary is based on laws, regulations, rulings and decisions in effect
on the date of this prospectus. Changes to existing law could have a
retroactive effect and could alter the tax consequences discussed below. No
rulings have been sought from the IRS with respect to the federal income tax
consequences, discussed

                                       30
<PAGE>

below, and no assurances can be given that the IRS will not take contrary
positions. The pass through trusts are not indemnified for any federal income
taxes that may be imposed upon them, and the imposition of those taxes on a
pass through trust could result in a reduction in the amounts available for
distribution to the certificateholders of that pass through trust. Prospective
investors should consult their own tax advisors with respect to the federal,
state, local and foreign tax consequences to them of the purchase, ownership
and disposition of the certificates.

Tax Treatment of the Pass Through Trusts and Certificateholders

   Each pass through trust will not itself be subject to U.S. federal income
taxation. Each U.S. certificateholder will be required to report on its federal
income tax return its pro rata share of the entire income from the secured
promissory notes and any other property held in the related pass through trust,
in accordance with the U.S. certificateholder's method of accounting.
Accordingly, each U.S. certificateholder's share of interest paid on the
secured promissory notes will be taxable as ordinary income, as it is paid or
accrued, and a U.S. certificateholder's share of any premium paid on redemption
of a secured promissory note will be treated as capital gain. If the proceeds
from the sale of certificates are invested with a depositary or held pursuant
to an escrow arrangement prior to the purchase of secured promissory notes by a
pass through trust, the resulting deposits may be subject to the original issue
discount rules, with the result that a U.S. certificateholder may be required
to include interest income from that deposit under the accrual method of
accounting regardless of its normal method. If certificates issued by a pass
through trust are supported by a liquidity facility, any amounts received by
the pass through trust under the liquidity facility for unpaid interest will be
treated for U.S. federal income tax purposes as having the same characteristics
as the payments they replace.

   Each U.S. certificateholder will be entitled to deduct, consistent with its
method of accounting, its pro rata share of fees and expenses paid or incurred
by the corresponding pass through trust as provided in Section 162 or 212 of
the Internal Revenue Code of 1986, referred to as the Code. Certain fees and
expenses, including fees paid to the pass through trustee and the provider of
the liquidity facility, if applicable, will be paid by parties other than the
certificateholders. These fees and expenses could be treated as constructively
received by the pass through trust, in which event a U.S. certificateholder
could be required to include in income and entitled to deduct its pro rata
share of the fees and expenses. If a U.S. certificateholder is an individual,
estate or trust, the deduction for the certificateholder's share of fees or
expenses will be allowed only to the extent that all of the certificateholder's
miscellaneous itemized deductions, including the certificateholder's share of
fees and expenses, exceed 2% of the certificateholder's adjusted gross income.
In addition, in the case of U.S. certificateholders who are individuals,
certain otherwise allowable itemized deductions will be subject generally to
additional limitations on itemized deductions under applicable provisions of
the Code.

Effect of Subordination on Certificateholders of Subordinated Trusts

   In the event that any pass through trust is subordinated in right of payment
to any other pass through trust and the subordinated trust receives less than
the full amount of the interest, principal or premium paid with respect to the
secured promissory notes held by it because of the subordination of the pass
through trust, the certificateholders of the subordinated trust would probably
be treated for federal income tax purposes as if they had (a) received as
distributions their full share of principal, interest, or premium, (b) paid
over to a preferred class of certificateholders an amount equal to their share
of the amount of the shortfall, and (c) retained the right to reimbursement of
the amount of the shortfall to the extent of future amounts payable to the
certificateholders of the subordinated trust on account of the shortfall.

   Under this analysis, (a) subordinated certificateholders incurring a
shortfall would be required to include as current income any interest or other
income of the subordinated trust that was a component of the shortfall, even
though such amount was in fact paid to a preferred class of certificateholders,
(b) a loss would only be allowed to subordinated certificateholders when their
right to receive reimbursement of the shortfall becomes

                                       31
<PAGE>

worthless (i.e., when it becomes clear that funds will not be available from
any source to reimburse the shortfall), and (c) reimbursement of the shortfall
prior to a claim of worthlessness would not be taxable income to
certificateholders because the amount reimbursed would have been included in
income. These results should not significantly affect the inclusion of income
for certificateholders on the accrual method of accounting, but could
accelerate inclusion of income to certificateholders on the cash method of
accounting by, in effect, placing them on the accrual method.

Original Issue Discount

   The secured promissory notes may be issued with original issue discount
("OID"). The prospectus supplement will state whether any secured promissory
notes to be held by the related pass through trust will be issued with OID.
Generally, a holder of a debt instrument issued with OID that is not negligible
must include such OID in income for federal income tax purposes as it accrues,
in advance of the receipt of the cash attributable to this income, under a
method that takes into account the compounding of interest.

Sale or Other Disposition of the Certificates

   Upon the sale, exchange or other disposition of a certificate, a U.S.
certificateholder generally will recognize capital gain or loss equal to the
difference between the amount realized on the sale or exchange (other than any
amount attributable to accrued interest which will be taxable as ordinary
income) and the U.S. certificateholder's adjusted tax basis in the secured
promissory notes and other property held by the corresponding pass through
trust. Any gain or loss will be long-term capital gain or loss to the extent
attributable to property held by the pass through trust for more than one year.
In the case of individuals, estates, and trusts, the maximum U.S. federal
income tax rate on long-term capital gains generally is 20%. In the event that
the proceeds from the sale of certificates are invested with a depositary or
held pursuant to an escrow arrangement prior to the purchase of secured
promissory notes by a pass through trust, any gain with respect to an interest
in the resulting deposits likely will be treated as ordinary income.

Foreign Certificateholders

   Under present U.S. federal income tax law, assuming certain certification
requirements are satisfied (which include identification of the beneficial
owner of a certificate), and subject to the discussion of backup withholding
below:

  .  interest paid (including any OID) on a certificate to, or on behalf of,
     any beneficial owner of a certificate that is not a U.S. person will not
     be subject to U.S. federal income tax or withholding tax provided that
     (a) the non-U.S. certificateholder does not actually or constructively
     own 10% or more of the total combined voting power of all classes of
     stock of an owner participant or us, (b) the non-U.S. certificateholder
     is not (A) a bank receiving interest pursuant to a loan agreement
     entered into in the ordinary course of its trade or business, or (B) a
     controlled foreign corporation for U.S. tax purposes that is related to
     an owner participant or us, and (c) the interest payments are not
     effectively connected with the non-U.S. certificateholder's conduct of a
     U.S. trade or business; and

  .  a non-U.S. certificateholder will not be subject to U.S. federal income
     tax on any capital gain realized on the sale, exchange or other
     disposition of a certificate, unless (a) the non-U.S. certificateholder
     is an individual who is present in the United States for 183 days or
     more during the taxable year of the sale or exchange and certain other
     requirements are met or (b) the gain is effectively connected with the
     non-U.S. certificateholder's conduct of a U.S. trade or business.

   The certification referred to above may be made on an IRS Form W-8 or
substantially similar substitute form.

Information Reporting and Backup Withholding

   In general, information reporting requirements will apply to certain
payments within the United States of principal, interest, OID and premium on
the certificates, and to payments of the proceeds of certain sales of

                                       32
<PAGE>

certificates made to U.S. certificateholders other than certain exempt
recipients (such as corporations). A 31% backup withholding tax may apply to
the payments if the holder fails or has failed to provide an accurate taxpayer
identification number or otherwise establish an exemption or fails to report in
full interest income. With respect to non-U.S. certificateholders, payments
made on a certificate and proceeds from the sale of a certificate owned by a
non-U.S. certificateholder will generally not be subject to information
reporting requirements or the backup withholding tax if the non-U.S.
certificateholder provides the required certification of its non-U.S. status or
otherwise establishes an exemption.

   Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules will be allowed as a refund or credit against the
certificateholder's U.S. federal income tax liability, if any, provided the
required information is furnished to the IRS.

   The Treasury Department recently issued final regulations governing backup
withholding and information reporting requirements. The regulations do not
significantly alter the substantive withholding and information reporting
requirements discussed above; they unify current certification procedures and
forms and clarify reliance standards. The regulations will generally become
effective for payments made after December 31, 2000.

                              ERISA CONSIDERATIONS

   Unless otherwise indicated in the applicable prospectus supplement, the
certificates may, subject to certain legal restrictions, be purchased and held
by an employee benefit plan subject to Title I of the Employee Retirement
Income Security Act of 1974, referred to as ERISA, or an individual retirement
account or an employee benefit plan subject to section 4975 of the Code. A
fiduciary of an employee benefit plan must determine that the purchase and
holding of a certificate is consistent with its fiduciary duties under ERISA
and does not result in a non-exempt prohibited transaction as defined in
section 406 of ERISA or section 4975 of the Code. Employee benefit plans which
are governmental plans, as defined in section 3(32) of ERISA, and certain
church plans, as defined in section 3(33) of ERISA, are not subject to Title I
of ERISA or section 4975 of the Code. The certificates may, subject to certain
legal restrictions, be purchased and held by such plans.

                              PLAN OF DISTRIBUTION

   Certificates may be sold to one or more underwriters for public offering and
sale by them to investors or other persons directly or through one or more
dealers or agents. Any underwriter, dealer or agent involved in the offer and
sale of the certificates will be named in an applicable prospectus supplement.

   The certificates may be sold from time to time in one or more transactions
at a fixed price or prices, which may be changed, at market prices prevailing
at the time of sale, at prices based on the prevailing market prices or at
negotiated prices. Dealer trading may take place in certain of the
certificates, including certificates not listed on any securities exchange. We
do not intend to apply for listing of the certificates on a national securities
exchange. We also may, from time to time, authorize underwriters acting as our
agents to offer and sell the certificates upon the terms and conditions as will
be set forth in any prospectus supplement. In connection with the sale of
certificates, underwriters may be deemed to have received compensation from us
in the form of underwriting discounts or commissions and may also receive
commissions from purchasers of certificates for whom they may act as agent.
Underwriters may sell certificates to or through dealers, and dealers may
receive compensation in the form of discounts, concessions or commissions from
the underwriters and/or commissions (which may be changed from time to time)
from the purchasers for whom they may act as agent.

   If a dealer is used directly by us in the sale of certificates in respect of
which this prospectus is delivered, the certificates will be sold to the
dealer, as principal. The dealer may then resell the certificates to the public
at varying prices to be determined by the dealer at the time of resale. Any
dealer used directly by us and the terms of any sale to that dealer will be set
forth in the related prospectus supplement.

   Certificates may be offered and sold through agents designated by us from
time to time. Any agent involved in the offer or sale of the certificates in
respect of which this prospectus is delivered will be named in, and any
commissions payable by us to that agent will be set forth in, the applicable
prospectus supplement. Unless otherwise indicated in the applicable prospectus
supplement, that agent will be acting on a best efforts basis for the period of
its appointment.

   We may directly solicit offers to purchase certificates and sales under
those offerings may be made by us directly to institutional investors or others
who may be deemed to be underwriters within the meaning of the Securities Act
of 1933 with respect to any resale of the certificates. We will describe the
terms of these sales will be described in the prospectus supplement. Except as
set forth in the applicable prospectus supplement, none of our directors,
officers or employees will solicit or receive a commission in connection with
our direct sales of the certificates, although those persons may respond to
inquiries by potential purchasers and perform ministerial and clerical work in
connection with any direct sales.

   Any underwriting compensation that we pay to underwriters, dealers or agents
in connection with the offering of certificates, and any discounts, concessions
or commissions that underwriters allow to participating dealers, will be set
forth in an applicable prospectus supplement. Underwriters, dealers and agents
participating in the distribution of the certificates may be deemed to be
underwriters, and any discounts and commissions received by them and any profit
realized by them on resale of the certificates may be deemed to be underwriting
discounts and commissions under the Securities Act. We may indemnify
underwriters, dealers and agents against certain civil liabilities, including
liabilities under the Securities Act. We may reimburse underwriters, dealers
and agents for expenses incurred in connection with the offer or sale of
certificates.

   Underwriters, dealers and agents may engage in transactions with, or perform
services for, us, our parent and our subsidiaries and affiliates in the
ordinary course of business.

   If so indicated in an applicable prospectus supplement and subject to
existing market conditions, we will authorize dealers acting as our agents to
solicit offers by certain institutions to purchase certificates at the public
offering price set forth in the prospectus supplement pursuant to delayed
delivery contracts providing for payment and delivery on the date or dates
stated in that prospectus supplement. Each contract will be for an amount not
less than, and the aggregate principal amount of certificates sold pursuant to
contracts will be equal to, the respective amounts stated in that prospectus
supplement. Institutions with whom contracts, when authorized, may be made
include commercial and savings banks, insurance companies, pension funds,
investment companies, educational and charitable institutions and other
institutions, in all cases be subject to our approval. Contracts will not be
subject to any conditions except that the purchase by an institution of the
certificates covered by its contracts will not at the time of delivery be
prohibited under the laws of any jurisdiction in the United States to which
that institution is subject. A commission indicated in the applicable
prospectus supplement will be granted to underwriters and agents soliciting
purchases of certificates pursuant to contracts accepted by us. Agents and
underwriters will have no responsibility in respect of the delivery or
performance of contracts.

   If any underwriter is utilized in the sale of any certificates, the
applicable prospectus supplement will contain a statement as to the intention,
if any, of the underwriter at the date of the prospectus supplement to make a
market in the certificates. No assurances can be given that there will be a
market for the certificates.

   The place and time of delivery for the certificates in respect of which this
prospectus is delivered will be set forth in the applicable prospectus
supplement.

                           SELLING CERTIFICATEHOLDERS

   Certificates issued pursuant to this prospectus may be reoffered pursuant to
this prospectus by the holders of certificates, from time to time, in
transactions on the open market, in negotiated transactions, through the
writing of options on the certificates or through a combination of these
methods of sale, at negotiated prices, fixed prices that may be changed, market
prices prevailing at the time of sale or prices relating to the prevailing
market prices. The selling certificateholders may effect these transactions by
selling the certificates to or through broker-dealers, and the broker-dealers
may receive compensation in the form of discounts, concessions or commissions
from the selling certificateholders, the purchasers of certificates for whom
the broker-dealer may act as agent or to whom they may sell as principal or
both. We will not receive any part of the proceeds from the resale by the
selling certificateholders of any certificates pursuant to this prospectus.
Unless otherwise provided in the applicable prospectus supplement, we will bear
all expenses, other than selling discounts and commissions and fees and
expenses of the selling certificateholders, in connection with the registration
of the certificates being reoffered by the selling certificateholders.

   The identity of the selling certificateholders, the number of certificates
sold by the selling certificateholders and the price per certificate will be
determined at the time of the consummation of the particular transaction.
Specific information regarding the transaction, the identity of the selling
certificateholders and the number of certificates to be resold may be provided
at the time of the applicable transaction by means of a supplement or a post-
effective amendment to this prospectus, as applicable.

   The selling certificateholders and any broker-dealers who act in connection
with the sale of those certificates may be deemed to be an "underwriter" within
the meaning of Section 2(11) of the Securities Act, and any commissions
received by them and profit on any resale of those certificates as principal
may be deemed to be underwriting discounts and commissions under the Securities
Act. We intend to make available public information concerning ourself in
compliance with the Securities Act and the related regulations and,
accordingly, Rule 144 or Rule 145 under the Securities Act may be available for
use by holders of certificates to effect transfers of those securities, subject
to compliance with the remaining provisions of those rules.

the opinion of counsel for the pass through trustee as to certain matters
relating to the authorization, execution and delivery of the certificates by,
