ECONOMIC OVERVIEW
--------------------------------------------------------------------------------


      Over the past six months, the U.S. economy grew rapidly and the
unemployment rate hovered around its 30-year low of 4 percent.
Historically, these conditions would have caused inflation to accelerate,
causing the Federal Reserve Board to tighten monetary policy. This time it was
no different. To implement this policy, the Fed responded with three rate
increases -- 25 basis points in February, 25 basis points in March and 50 basis
points at the May 16th Federal Open Market Committee meeting. At this time, it
appears that the Fed's actions are beginning to have the desired effect, with
market sentiment reflecting the transition to a possible slowdown in economic
growth.

     The shift in market sentiment follows a stream of economic reports that
evidence slowing in various sectors of the economy. Housing sales and
construction, while still robust, have fallen from peak levels. This is not
surprising as higher interest rates have had a direct impact on housing costs.
The moderation in housing activity also affects the demand for furniture and
other household goods, contributing to a slowing in the manufacturing sector.
However, oil prices continue to remain high, even as OPEC promises to raise
production quotas. As a result, although the inflation indicators are ticking up
at the headline level, producer and consumer prices at the core level remain
benign.

     Due to the market conditions over the last six months, the Money Market
Mileage Funds maintained a short weighted-average maturity during most of the
period. However, when the market sentiment began to shift, the Funds began to
extend the weighted-average maturity in order to establish a more neutral
posture toward the end of June.

1   Past performance is not indicative of future performance. An investment in
    this Fund is neither insured nor guaranteed by the Federal Deposit Insurance
    Corporation or any other government agency. Although the Fund seeks to
    preserve the value of an investment at $1.00 per share, it is possible to
    lose money by investing in this Fund.

2   The Fund's performance is derived from a combination of the Fund's
    performance and that of another fund (the "Companion Fund") not included in
    this report. The Companion Fund has been managed by AMR Investments since
    its inception on September 1, 1987. Like the Fund, the Companion Fund
    invests all of its investable assets in a corresponding Portfolio of the AMR
    Investment Services Trust. The performance results from inception through
    October 31, 1995 are those of the Companion Fund. (Results through October
    31, 1991 are for the Companion Fund's Institutional Class of shares and from
    November 1, 1991 through October 31, 1995 are for the Companion Fund's
    Mileage Class of shares.) The Fund began offering it shares on November 1,
    1995. Thus, performance results shown from that date through June 30, 2000
    are for the Fund. Because the Companion Fund had lower expenses, its
    performance was better than the Fund would have realized in the same period.

    1995. Performance results shown from that date through January 28, 1996 are
    for the initial class of Fund shares. The Platinum Class of the Fund began
    offering its shares on January 29, 1996. Thus, performance results from that
    date through June 30, 2000 are for the Platinum Class of Fund shares.
    Because the Companion Fund and the Fund's initial class had lower expenses,
    their performance was better than the Fund would have realized in the same
    period.

     AMR Investment Services Trust. The performance results from inception
     through October 31, 1995 are those of the Companion Fund's Mileage Class of
     shares. The Fund began offering it shares on

     November 1, 1995. Thus, performance results shown from that date through
     June 30, 2000 are for the Fund. Because the Companion Fund had lower
     expenses, its performance was better than the Fund would have realized in
     the same period.

3    The Fund's performance is derived from a combination of the Fund's
     performance and that of another fund (the "Companion Fund") not included in
     this report. The Companion Fund has been managed by AMR Investments since
     its inception on November 10, 1993. Like the Fund, the Companion Fund
     invests all of its investable assets in a corresponding Portfolio of the
     AMR Investment Services Trust. The performance results from inception
     through October 31, 1995 are those of the Companion Fund's Mileage Class of
     shares. The Fund began offering it shares on November 1, 1995. Performance
     results shown from that date through October 31, 1999 are for the initial
     class of Fund shares. The Platinum Class of the Fund began offering its
     shares on November 1, 1999. Thus, performance results from that date
     through June 30, 2000 are for the Platinum Class of Fund shares. Because
     the Companion Fund and the Fund's initial class had lower expenses, their
     performance was better than the Fund would have realized in the same
     period.

1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     American AAdvantage Mileage Funds (the "Trust") is organized as a
Massachusetts business trust under a Declaration of Trust dated February 14,
1995 and is registered under the Investment Company Act of 1940 (the "Act"), as
amended, as a no-load, open-end management investment company with ten separate
series. The following series are included in this report: American AAdvantage
Money Market Mileage Fund, American AAdvantage U.S. Government Money Market
Mileage Fund and American AAdvantage Municipal Money Market Mileage Fund (each a
"Fund" and collectively the "Funds"). The Funds commenced active operations on
November 1, 1995. The Money Market Mileage Fund commenced sales of a second
class of shares designated as "Platinum Class" on January 29, 1996. At the same
time, the existing shares of the Money Market Mileage Fund were redesignated as
"Mileage Class" shares. The U.S. Government Money Market and Municipal Money
Market Mileage Funds commenced sales of a second class of shares designated as
"Platinum Class" on November 1, 1999. At the same time, the existing shares of
the U.S. Government Money Market and Municipal Money Market Mileage Funds were
redesignated as "Mileage Class" shares.

     Each Fund invests all of its investable assets in the corresponding
portfolio of the AMR Investment Services Trust, an open-end diversified
management investment company, as follows:

<TABLE>
    <S>                                               <C>                     <C>
    AMERICAN AADVANTAGE:                              INVESTS ASSETS IN       AMR INVESTMENT SERVICES TRUST:
    Money Market Mileage Fund                                                 Money Market Portfolio
    U.S. Government Money Market Mileage Fund                                 U.S. Government Money Market Portfolio
    Municipal Money Market Mileage Fund                                       Municipal Money Market Portfolio
</TABLE>

     Each AMR Investment Services Trust Portfolio has the same investment
objectives as its corresponding Fund. The value of such investment reflects each
Fund's proportionate interest in the net assets of the corresponding portfolio
(17.84%, 10.51% and 23.40% at June 30, 2000 of the AMR Investment Services Money
Market, U.S. Government Money Market and Municipal Money Market Portfolios,
respectively) (each a "Portfolio" and collectively the "Portfolios"). The
financial statements of the Portfolios are included elsewhere in this report and
should be read in conjunction with the Funds' financial statements.

     AMR Investment Services, Inc. (the "Manager") is a wholly-owned subsidiary
of AMR Corporation, the parent company of American Airlines, Inc. ("American"),
and was organized in 1986 to provide business management, advisory,
administrative and asset management consulting services to the Trust and other
investors.

NOTES TO FINANCIAL STATEMENTS -- CONTINUED

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

     The following is a summary of the significant accounting policies followed
by the Funds.

  Valuation of Investments

     Valuation of securities by the Portfolios is discussed in Note 1 of the
Portfolios' Notes to Financial Statements which are included elsewhere in this
report.

  Investment Income and Dividends to Shareholders

     Each Fund records its share of net investment income (loss) and realized
gain (loss) in the Portfolio each day. All net investment income (loss) and
realized gain (loss) of each Portfolio are allocated pro rata among the
corresponding Fund and other investors in each Portfolio at the time of such
determination. The Funds generally declare dividends daily from net investment
income and net short-term capital gain, if any, payable monthly.

     Dividends are determined in accordance with income tax principles which may
treat certain transactions differently than generally accepted accounting
principles.

  Federal Income and Excise Taxes

     It is the policy of each of the Funds to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all net investment income as well as any net realized
capital gains on the sale of investments. Therefore, no federal income or excise
tax provision is required.

     All dividends paid by the Municipal Money Market Mileage Fund were
"exempt - interest dividends", and therefore are 100% free of any regular
federal income tax. Approximately 44% of interest earned was derived from
investments in certain private activity bonds for purposes of the federal
alternative minimum tax calculation.

  Deferred Organization Costs

     Expenses incurred by the Funds in connection with their organization are
being amortized on a straight-line basis over a five-year period.

  Expenses

     Expenses directly attributable to a Fund are charged to that Fund's
operations. Expenses directly attributable to a Class of shares are charged to
that Class. Expenses incurred by the Trust with respect to any two or more of
the Funds are allocated in proportion to the net assets of each Fund, except
where allocations of direct expenses to each Fund can otherwise be made fairly.
Each share of each Fund, regardless of class, bears equally those expenses that
are allocated to the Fund as a whole.

  Valuation of Shares

     The price per share is calculated separately for each class of each Fund on
each day on which shares are offered for sale and orders accepted or upon
receipt of a redemption request. With respect to a class of a Fund, price per
share is computed by dividing the value of the Class' pro rata allocation of the
Fund's investments and other assets, less liabilities, by the number of Class
shares outstanding.

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimated.

2.   TRANSACTIONS WITH AFFILIATES

  Management Agreement

     The Manager and the Trust entered into a Management Agreement which
obligates the Manager to provide or oversee administrative and management
services to the Funds. As compensation for performing the duties required under
the Management Agreement, the Manager receives an annualized fee of .10% of the
net assets of each of the Funds.

  Administrative Services Plan

     The Trust has adopted an Administrative Services Plan with respect to the
Platinum Class of the Funds. As compensation for providing administrative
services, the Manager receives an annual fee of .55% of the average daily net
assets of each of the Platinum Classes of the Funds.

  Distribution Plan

     The Trust has adopted a Distribution Plan (the "Plan") pursuant to Rule
12b-1 under the Act. A separate plan has been adopted by the Mileage Class and
Platinum Class of the Funds. Under each Plan, as compensation for distribution
assistance, the Manager receives an annual fee of .25% of the average daily net
assets of each Class or Fund. The fee will be payable without regard to whether
the amount of the fee is more or less than the actual expenses incurred in a
particular month by the Manager for distribution assistance. During the six
months ended June 30, 2000, the Manager waived distribution fees totaling
$31,460 and $1,572, respectively for the U.S. Government Money Market Mileage
Fund and the Municipal Money Market Mileage Fund. During the same period, the
Manager waived $1,387 for the Money Market Mileage Fund - Platinum Class.

  Other

     Certain officers or trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Unaffiliated trustees and their spouses are provided
free unlimited air transportation on American. However, the Trust compensates
each trustee with payments in an amount equal to the trustee's income tax on the
value of this free airline travel. One trustee, as a retiree of American,
already receives flight benefits. Prior to March 1, 2000, the Trust compensated
this trustee up to $10,000 annually to cover his personal flight service charges
and the charges for his three adult children, as well as the income tax charged
on the value of these benefits. Beginning March 1, 2000, the trustee will
receive an annual retainer of $20,000 plus $1,250 for each Board meeting
attended. For the six months ended June 30, 2000, the cost of air transportation
for the trustees was not material to any of the Funds.

AMR INVESTMENT SERVICES TRUST
NOTES TO FINANCIAL STATEMENTS
June 30, 2000 (Unaudited)
--------------------------------------------------------------------------------
1.   ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES

     AMR Investment Services Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended, as a no-load, open-end management
investment company which was organized as a trust under the laws of the State of
New York pursuant to a Declaration of Trust dated as of June 27, 1995 and
amended on August 11, 1995. Beneficial interests in the Trust are divided into
ten separate series, each having distinct investment objectives and policies.
These financial statements relate to the AMR Investment Services Money Market
Portfolio, the AMR Investment Services U.S. Government Money Market Portfolio
and the AMR Investment Services Municipal Money Market Portfolio (each a
"Portfolio" and collectively the "Portfolios"). The assets of each Portfolio
belong only to that Portfolio, and the liabilities of each Portfolio are borne
solely by that Portfolio and no other. The Trust commenced active operations on
November 1, 1995.

     AMR Investment Services, Inc. (the "Manager") is a wholly-owned subsidiary
of AMR Corporation, the parent company of American Airlines, Inc. ("American"),
and was organized in 1986 to provide business management, advisory,
administrative and asset management consulting services.

     The following is a summary of the significant accounting policies followed
by the Portfolios.

  Security Valuation

     Securities of the Portfolios are valued using the amortized cost method. In
the event that a deviation of 1/2 of 1% or more exists between the $1.00 per
share price of the Portfolios, calculated at amortized cost, and the price per
share calculated by reference to market quotations, or if there is any other
deviation which the Board believes would result in a material dilution to
shareholders or purchasers, the Board will promptly consider the appropriate
action which should be initiated.

  Security Transactions and Investment Income

     Security transactions are recorded on the trade date of the security
purchase or sale. Interest income is earned from settlement date, recorded on
the accrual basis, and adjusted, if necessary, for amortization of premiums or
accretion of discounts on investment grade short-term securities and zero coupon
instruments. For financial and tax reporting purposes, realized gains and losses
are determined on the basis of specific lot identification.

  Federal Income and Excise Taxes

     The Portfolios will be treated as partnerships for federal income tax
purposes. As such, each investor in a Portfolio will be taxed on its share of
the Portfolio's ordinary income and capital gains. It is intended that each
Portfolio's assets will be managed in such a way that an investor in the
Portfolio will be able to satisfy the requirements of sub-chapter M of the
Internal Revenue Code.

  Repurchase Agreements

     Under the terms of a repurchase agreement, securities are acquired by a
Portfolio from a securities dealer or a bank which are subject to resale at a
later date. Repurchase agreements are fully collateralized by U.S. Treasury or
Government agency securities. All collateral is held at the Portfolio's
custodian bank, State Street Bank and Trust Company, or at subcustodian banks.
The collateral is monitored daily by each Portfolio so that the collateral's
market value exceeds the carrying value of the repurchase agreement.

AMR INVESTMENT SERVICES TRUST
NOTES TO FINANCIAL STATEMENTS -- CONTINUED
June 30, 2000 (Unaudited)
--------------------------------------------------------------------------------

  Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimated.

2.   TRANSACTIONS WITH AFFILIATES

  Management Agreement

     The Trust and the Manager are parties to a Management Agreement which
obligates the Manager to provide or oversee the provision of all administrative,
investment advisory and portfolio management services. The Manager serves as the
sole investment adviser to each of the Portfolios. Pursuant to the Management
Agreement, the Manager receives from the Portfolios an annualized fee equal to
 .10% of the average daily net assets of each of the Portfolios.

  Other

     Certain officers or trustees of the Trust are also current or former
officers or employees of the Manager or American. The Trust makes no direct
payments to its officers. Unaffiliated trustees and their spouses are provided
free unlimited air transportation on American. However, the Trust compensates
each trustee with payments in an amount equal to the trustee's income tax on the
value of this free airline travel. One trustee, as a retiree of American,
already receives flight benefits. Prior to March 1, 2000, the Trust compensated
this trustee up to $10,000 annually to cover his personal flight service charges
and the charges for his three adult children, as well as the income tax charged
on the value of these benefits. Beginning March 1, 2000, the trustee will
receive an annual retainer of $20,000 plus $1,250 for each Board meeting
attended. For the six months ended June 30, 2000, the cost of air transportation
for the trustees was not material to any of the Portfolios.
