Item 5.   Other Events.


          Preview Travel, Inc., a Delaware corporation (the "registrant" or
"Preview"), Sabre Inc., a Delaware corporation ("Sabre"), Travelocity
Holdings, Inc., a Delaware corporation and a wholly-owned subsidiary of Sabre
("Travelocity Holdings"), and Travelocity.com Inc., a Delaware corporation
and a wholly-owned subsidiary of Travelocity Holdings ("Travelocity.com"),
have entered into an Agreement and Plan of Merger, dated as of October 3,1999
(the "Merger Agreement"), whereby Preview Travel will be merged with and
into Travelocity.com, with Travelocity.com as the surviving entity (the
"Merger").

          As a result of the Merger, each outstanding share of Preview common
stock will be converted into the right to receive one share of  common stock,
par value $.001 per share, of Travelocity.com (the "Travelocity.com Common
Stock").

          While the Merger Agreement prohibits Preview from soliciting
competing acquisition proposals, Preview may provide non-public information
to, and engage in negotiations and discussions with respect to, an
unsolicited superior proposal made to Preview.  Furthermore, subject to
compliance with the terms of the Merger Agreement and payment of a $10
million fee to Saturn, Preview may terminate the Merger Agreement and accept
a superior proposal.

          Concurrently with the execution and delivery of the Merger
Agreement, certain stockholders of the registrant entered into voting
agreements (the "Voting Agreements"). Under the Voting Agreements, the
stockholders commit to vote for the approval of the Merger and against any
competing acquisition proposals until the Voting Agreements terminate.  The
Voting Agreements terminate automatically upon the earlier of  termination of
the Merger Agreement and the effective time of the Merger.

          The closing of the Merger is subject to certain conditions,
including the approval of the common stockholders of Preview and the receipt
of approvals pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended.

          In connection with the Merger Agreement, Preview's Board of
Directors has authorized the amendment of its Rights Agreement dated as of
October 29, 1998 in order to render the rights issued thereunder inapplicable
to the Merger Agreement and the transactions contemplated thereby.

          Copies of the Merger Agreement, the Voting Agreements, the
amendment to the Rights Agreement and the press release, dated October 4,
1999, relating to the above-described transactions, are attached exhibits to
this report and are incorporated herein by reference.

Section 2.2.

          (c)  Notwithstanding any other provisions of this Agreement, no
dividends or other distributions on Travelocity.com Common Stock shall be

to Travelocity.com, they shall be canceled and exchanged for certificates for
shares of Travelocity.com Common Stock pursuant to this Agreement in
accordance with the procedures set forth in this Article II.

          (e)  Any portion of the Exchange Fund that remains unclaimed by the

not theretofore complied with this Article II shall thereafter look only to
Travelocity.com for payment of their shares of Travelocity.com Common Stock,
and unpaid dividends and distributions on the Travelocity.com Common Stock
deliverable in respect of each share of Preview Common Stock such stockholder
holds as determined pursuant to this Agreement, in each case, without any
interest thereon.

          (f)  None of Travelocity.com, Preview, the Exchange Agent or any
other person shall be liable to any former holder of shares of Preview Common
Stock for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.

          (g)  In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
Travelocity.com, the posting by such person of a bond in such reasonable
amount as Travelocity.com may direct as indemnity against any claim that may
be made against it with respect to such Certificate, the Exchange Agent will
issue in exchange for such lost, stolen or destroyed Certificate the shares
of Travelocity.com Common Stock and unpaid dividends and distributions on
shares of Travelocity.com Common Stock deliverable in respect thereof
pursuant to this Agreement.

     Section 2.3    Stock Options and Equity Awards.  (a)  At the Effective
Time, each outstanding employee, director or consultant option to purchase

Preview's Stock Option Plans or otherwise, whether vested or not vested,
shall be assumed by Travelocity.com.  As of and after the Effective Time
(i) each Preview Stock Option then outstanding shall be converted into a

Preview Stock Option shall be an amount equal to the exercise price per share

options to acquire such shares) issuable pursuant to this Agreement shall be
appropriately adjusted to provide the holders of shares of Preview Common

accurate and complete copies of all documents embodying each Preview Benefit

its Subsidiaries taken as a whole under the relevant Preview Benefit Plan).

          (c)  All Preview Benefit Plans have been administered in all
respects in accordance with the terms thereof and all applicable laws except
for violations which, individually or in the aggregate, would not reasonably

Service, and Preview is not aware of any circumstances that would reasonably
be expected to result in the revocation or denial of this qualified status.
Except as otherwise set forth in the Preview Disclosure Schedule or in the
Preview SEC Reports filed prior to this date, as of the date hereof there is
no pending or, to Preview's knowledge, threatened, material claim,
litigation, proceeding, audit, examination or investigation relating to any

Preview Benefit Plan have been made.  No Preview Pension Plan has an
"accumulated funding deficiency" (whether or not waived) within the meaning
of Section 412 of the Code or Section 302 of ERISA.  Neither Preview nor any
Subsidiary of Preview nor any Preview ERISA Affiliate has provided, or is
required to provide, security to any Preview Pension Plan pursuant to Section
401(a)(29) of the Code.

          (f)  As of the date of this Agreement, none of Preview, any
Subsidiary of Preview or any Preview ERISA Affiliate have incurred any
withdrawal liability (within the meaning of Section 4201 of ERISA) to any
Preview Multiemployer Plan, which liability has not previously been fully
satisfied.  None of Preview, any Subsidiary of Preview or any Preview ERISA
Affiliate has knowledge that any Preview Multiemployer Plan fails to qualify
under Section 401(a) of the Code, is insolvent or is in reorganization within
the meaning of Part 3 of Subtitle E of Title IV of ERISA or of any condition
that would reasonably be expected to result in a Preview Multiemployer Plan
becoming insolvent or going into reorganization.

          (g)  Except as set forth in the Preview Disclosure Schedule, the

diligent manner and there is no fact or circumstance of which Preview is
aware that will cause the Year 2000 Plan not to result in the Systems being
Year 2000 Compliant; and (c) the Year 2000 Plan includes the steps necessary
to ascertain whether third party vendors upon whom Preview relies for goods

rise to any right of termination, modification, cancellation, suspension,
limitation, revocation or acceleration under the AOL Agreements by either
Preview or AOL.  Preview has no reason to believe that AOL will not be able
to fulfill all of its obligations under the AOL Agreements and, as of the
date hereof, Preview has not been notified that AOL intends to cancel,

adverse to Sabre its recommendation to Preview's stockholders that they give
the Required Preview Vote, only (w) if after receiving an Acquisition
Proposal that constitutes a Superior Proposal, the Board of Directors of
Preview determines in its good faith judgment, after receiving the advice of
outside legal counsel, that, in light of this Superior Proposal, the Board of
Directors would be in violation of its fiduciary duties under applicable law
if it failed not to take such action, (x) if three Business Days have elapsed
following delivery by Preview to Sabre of written notice advising Sabre that
the Board of Directors of Preview intends to resolve to take such action
absent modification to the terms and conditions of this Agreement, (y) if,
assuming this Agreement were amended to reflect all adjustments to the terms
and conditions hereof proposed by Sabre during such three Business Day
period, such Acquisition Proposal would nonetheless constitute a Superior

law), and (ii) consistent with its legal obligations, all other information
concerning its business, properties and personnel as such other party may

Sabre and Preview shall each cooperate with the other and use (and shall

governmental authority in connection with the Merger and the other
transactions contemplated by this Agreement.

          (b)  Without limiting Section 6.3(a), Preview and Sabre shall each
use its reasonable best efforts to avoid the entry of, or to have vacated or
terminated, any decree, order, or judgment that would restrain, prevent or
delay the Closing, on or before the Termination Date, including without
limitation defending through litigation on the merits any claim asserted in
any court by any Person.

          (c)  Each of Sabre, Travelocity Holdings, Travelocity.com and
Preview shall use its reasonable best efforts to cause the Merger to qualify,
and will not (both before and after consummation of the Merger) take any
actions which to its knowledge could reasonably be expected to prevent the
Merger from qualifying, as a reorganization under the provisions of Section
368 of the Code.

     Section 6.4    No Solicitation.  (a)  Each of Preview and its
Subsidiaries will not, and will use its reasonable best efforts to cause its

indirectly, take any action to solicit, initiate, knowingly encourage or
knowingly facilitate the making of any Acquisition Proposal (including
without limitation, by amending, or granting any waiver under, the Rights
Agreement) or any inquiry with respect thereto or engage in discussions or
negotiations with any Person with respect thereto, or in connection with any
Acquisition Proposal or potential Acquisition Proposal, disclose any
nonpublic information relating to it or its Subsidiaries or afford access to
the properties, books or records of it or its Subsidiaries to, any Person

Acquisition Proposal; provided, however, that, in the event that prior to
receipt by Preview of the Required Preview Vote, (i) Preview shall receive a
Superior Proposal that was not solicited by it and did not otherwise result
from a breach of this Section 6.4, (ii) the Board of Directors of Preview,
determines in its good faith judgment, after receiving the advice of outside
counsel that, in light of this Superior Proposal, if Preview fails to
participate in such discussions or negotiations with, or to provide such
information or access to, the party making the Superior Proposal, it would be
in violation of its fiduciary duties under applicable law, and (iii) after
giving Sabre 24 hours' notice of its intention to do so, Preview may
(x) furnish information or access with respect to it and its Subsidiaries to
the Person making such Superior Proposal pursuant to a customary
confidentiality agreement containing terms generally no less restrictive than
the terms contained in the Confidentiality Agreement, provided that a copy of
all such written information is simultaneously, or has been previously,
provided to Sabre and (y) participate in discussions and negotiations
regarding such Superior Proposal; and provided, further, that after receipt
of an unsolicited, written, bona fide Acquisition Proposal that the Board of
Directors of Preview reasonably concludes may constitute a Superior Proposal,
Preview may on one occasion submit to the party making such Acquisition
Proposal a written list of questions, the sole purpose of which is to elicit
clarifications as to the material terms of the Acquisition Proposal so as to
enable the Board of Directors of Preview to make a determination whether such
Acquisition Proposal is in fact a Superior Proposal (it being agreed that any
correspondence with such party shall be limited to questions and such
questions shall be limited to the purpose of clarifying the material terms of
such Acquisition Proposal and shall not solicit or encourage any new
Acquisition Proposal or any change to the Acquisition Proposal).

          (b)  Nothing contained in this Agreement shall prevent the Board of

of Directors of Preview shall not recommend that the stockholders of Preview
tender their shares in connection with a tender offer except to the extent,
after receiving a Superior Proposal, the Board of Directors of Preview
determines in its good faith judgment, after receiving the advice of outside
legal counsel, that, in light of the Superior Proposal, the Board of


                                     -47-

<PAGE>

Directors would be in violation of its fiduciary duties under applicable law
if it fails to make such a recommendation.

          (c)  If Preview or any Subsidiary of Preview receives an
Acquisition Proposal, Preview will (A) promptly (and in no event later than
24 hours after receipt of any Acquisition Proposal) notify (which notice
shall be provided orally and in writing and shall identify the Person making
the Acquisition Proposal and set forth the material terms thereof) Sabre of
the receipt of the Acquisition Proposal, or any request for non-public
information relating to Preview or any Subsidiary of Preview or for access to
the properties, books or records of Preview or any Subsidiary of Preview by
any Person that has made, or to Preview or any Subsidiary's knowledge may be
considering making, an Acquisition Proposal, and (B) will keep Sabre
reasonably informed of any changes to the material terms of any such
Acquisition Proposal or request.  Preview shall, and shall cause its
Subsidiaries to, immediately cease and cause to be terminated, and use
reasonable best efforts to cause its officers, directors, employees,
investment bankers, consultants, attorneys, accountants, agents and other
representatives to, immediately cease and cause to be terminated, all
discussions and negotiations, if any, that have taken place prior to the date
hereof with any Persons with respect to any actual or potential Acquisition
Proposal.

     For purposes of this Agreement, "Acquisition Proposal" means any offer
or proposal for, or any indication of interest in, any (i) direct or indirect
acquisition or purchase of a business or asset of Preview or any of its
Subsidiaries that constitutes 20% or more of the net revenues or assets of

acquisition or purchase of 20% or more of any class of equity securities of
Preview or any of its Subsidiaries whose business constitutes 20% or more of
the net revenues or assets of Preview and its Subsidiaries, taken as a whole;

any Person beneficially owning 20% or more of any class of equity securities
of Preview or any of its Subsidiaries whose business constitutes 20% or more
of the net revenues or assets of Preview and its Subsidiaries, taken as a
whole; or (iv)  merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction involving
Preview or any of its Subsidiaries whose business constitutes 20% or more of
the net revenue or assets of Preview and its Subsidiaries, taken as a whole,
other than the transactions contemplated by this Agreement.  For purposes of
this Agreement, "Superior Proposal" means any bona fide written Acquisition
Proposal for or in respect of more than 50 percent of the outstanding shares
of Preview Common Stock on terms that the Board of Directors of Preview
determines in its good faith judgment (after consultation with a financial
advisor of nationally recognized reputation and taking into account all the
terms and conditions of the Acquisition Proposal deemed relevant by Preview's
Board of Directors, including any break-up fees, expense reimbursement

                                     -48-

favorable from a financial point of view to its stockholders than the Merger.

of the distribution of rights issued pursuant to the Preview Rights Agreement
following the commencement of a tender offer or an exchange offer for Preview
Common Stock.

          (e)  Each of Preview and its Subsidiaries agrees that it will take
the necessary steps promptly to inform its officers, directors, investment
bankers, consultants, attorneys, accountants, agents and other
representatives, as appropriate, of the obligations undertaken in this
Section 6.4.

     Section 6.5    Employee Matters.  Preview and Sabre agree that the
individuals who immediately prior to the Effective Time are employees of

the Effective Time, be provided with employee benefits that are no less
advantageous in the aggregate to (in Sabre's discretion) either (i) the
employee benefits provided to the Continuing Employees immediately prior to
the Effective Time or (ii) the employee benefits provided to those
individuals who following the Effective Time are employees of Travelocity.com
LP, other than the Continuing Employees (but excluding in any event awards
under stock option and other equity-based plans and flight benefit
privileges); and provided, that nothing herein shall limit the right of any
entity to make such changes to any employee benefit plan or arrangement as
may be necessary to conform a plan or arrangement with applicable law or to

                                                             Exhibit 4.1

                                                    EXECUTION COPY


                               VOTING AGREEMENT


          THIS VOTING AGREEMENT, dated as of October __, 1999 (the
"Agreement"), is made by and between Sabre Inc., a Delaware corporation
("Sabre"), and America Online, Inc. (the "Stockholder").  Capitalized terms
not otherwise defined herein shall have the respective meanings set forth in
the Merger Agreement (as defined below).

          WHEREAS, simultaneously herewith, Sabre, Travelocity Holdings,
Inc., a Delaware corporation and a wholly-owned subsidiary of Sabre
("Travelocity Holdings"), Travelocity.com, a Delaware corporation and a
wholly-owned subsidiary of Travelocity Holdings ("Travelocity.com"), and
Preview Travel, Inc., a Delaware corporation ("Preview"), have entered into
an Agreement and Plan of Merger, dated as of the date hereof (the "Merger
Agreement"), pursuant to which Preview has agreed, subject to certain terms
and conditions, to merge with and into Travelocity.com (the "Merger");

          WHEREAS, the Stockholder is a stockholder of Preview and has voting
power with respect to the number of shares (the "Shares") of common stock of
Preview (the "Preview Common Stock") set forth below the Stockholder's
signature hereto; and

          WHEREAS, in order to induce Sabre, Travelocity Holdings and
Travelocity.com to enter into the Merger Agreement and to provide reasonable
assurances that the transactions contemplated by the Merger Agreement will be
consummated, the Stockholder is making certain agreements regarding the
Shares upon the terms and subject to the conditions set forth below.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained in this Agreement, and intending to be
legally bound hereby, the parties hereto agree as follows:

     1.   Voting of Shares; Grant of Irrevocable Proxy; Appointment of Proxy.

          (a)  The Stockholder agrees to vote all of its Shares of Preview
Common Stock, Shares of Preview Common Stock of any entity controlled by the
Stockholder and any Shares of Preview Common Stock hereafter acquired by the
Stockholder or by any person controlled by the Stockholder (collectively, the
"Stockholder's Shares") as follows:

               (i)  At any meeting of Preview stockholders called to vote
upon the Merger or the Merger Agreement or at any adjournment thereof or in
any other circumstances upon which a vote, consent or other approval with
respect to the Merger or the Merger Agreement is sought (the "Preview

<PAGE>

Stockholders' Meeting"), the Stockholder shall vote (or cause to be voted)
all of the Stockholder's Shares in favor of the Merger, the execution and
delivery by Preview of the Merger Agreement and the approval of the terms
thereof, and each of the other transactions contemplated by the Merger
Agreement.

               (ii) At any meeting of Preview stockholders or at any
adjournment thereof or in any other circumstances upon which their vote,
consent or other approval is sought, the Stockholder shall vote (or cause to
be voted) all of the Stockholder's Shares against (A) the approval of any
Acquisition Proposal or (B) any amendment of Preview's Certificate of
Incorporation or Bylaws or other proposal or transaction involving Preview or
any of its subsidiaries which amendment or other proposal or transaction
would in any manner impede, frustrate, prevent or nullify the Merger, the
Merger Agreement or any of the other transactions contemplated by the Merger
Agreement.

          (b)  The Stockholder hereby irrevocably grants to, and appoints,
Sabre and Donald J. Carty, Acting Chief Executive Officer of Sabre, and
Jeffrey M. Jackson, Chief Financial Officer of Sabre, in their respective
capacities as officers of Sabre, and any individual who shall hereafter
succeed to any such office of Sabre, and each of them individually, its proxy
and attorney-in-fact, with full power of substitution, for and in the name,
place and stead of the Stockholder, to vote upon and act with respect to all
of the Stockholder's Shares as set forth in subsections (a)(i) and (a)(ii) of
this Section 1.  The Stockholder represents that any proxies heretofore given
in respect of the Stockholder's Shares are not irrevocable, and that any such
proxies are hereby revoked.  The Stockholder hereby affirms that the
irrevocable proxy set forth in this Section 1(b) is given in connection with
the execution of the Merger Agreement, and that such irrevocable proxy is
given to secure the performance of the duties of the Stockholder under this
Agreement.  The Stockholder hereby further affirms that the irrevocable proxy
is coupled with an interest and may under no circumstances be revoked.  The
Stockholder hereby ratifies and confirms all that such irrevocable proxy may
lawfully do or cause to be done by virtue hereof.  Such irrevocable proxy is
executed and intended to be irrevocable in accordance with the provisions of
Section 212 of the Delaware General Corporation Law.  This proxy shall
survive the bankruptcy, merger, dissolution or liquidation of the
Stockholder.  In the event that the stockholders of Preview take action to
approve the Merger and the Merger Agreement by written consent in lieu of a
meeting of stockholders, the Stockholder will execute such consent and
provide a copy to Sabre.

     2.   Certain Events.  The Stockholder agrees that this Agreement and the
obligations hereunder shall attach to the Stockholder's Shares and shall be
binding upon any person or entity to which legal or beneficial ownership of
any or all of the Stockholder's Shares shall pass, whether by operation of

                                      -2-

<PAGE>

law or otherwise, including without limitation, the Stockholder's successors
or assigns.  In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of
Preview affecting the Preview capital stock, or the acquisition of additional
shares of Preview capital stock or other voting securities of Preview by the
Stockholder, the number of the Stockholder's Shares subject to the terms of
this Agreement shall be adjusted appropriately and this Agreement and the
obligations hereunder shall attach to any additional shares of Preview
capital stock or other voting securities of Preview issued to or acquired by
the Stockholder.

     3.   Representation and Warranties of the Stockholder.  The Stockholder
hereby represents and warrants to Sabre that:

          (a)  The Stockholder is the record and/or beneficial owner of the
number of Shares listed below its signature hereto.

          (b)  This Agreement has been duly authorized, executed and
delivered by, and constitutes a valid and binding agreement of, the
Stockholder, enforceable against the Stockholder in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other similar laws of general
application respecting creditors' rights and by general equitable principles.

          (c)  Neither the execution and delivery of this Agreement nor the
consummation by the Stockholder of the transactions contemplated hereby will
result in a violation of, or a default under, or conflict with, any contract,
trust, commitment, agreement, understanding, arrangement or restriction of
any kind to which the Stockholder is a party or bound or to which the
Stockholder's Shares are subject.  If the Stockholder is married and the
Stockholder's Shares constitute community property, this Agreement has been
duly authorized, executed and delivered by, and constitutes a valid and
binding agreement of, the Stockholder's spouse, enforceable against such
person in accordance with its terms.  Consummation by the Stockholder of the
transactions contemplated hereby will not violate, or require any consent,
approval, or notice under, any provision of any judgment, order, decree,
statute, law, rule or regulation applicable to the Stockholder or the
Stockholder's Shares.

          (d)  The Stockholder's Shares and the certificates representing the
Stockholder's Shares are now, and at all times will be, held by the
Stockholder, or by a nominee or custodian for the benefit of such
Stockholder, free and clear of all liens, security interest, proxies, voting
trusts or voting agreements or any other encumbrances whatsoever, except for
any such encumbrances or proxies arising hereunder.

          (e)  No broker, investment banker, financial adviser or other
person is entitled to any broker's, finder's, financial adviser's or other
similar fee or commission in connection with the transactions contemplated
hereby based upon arrangements made by or on behalf of the Stockholder.

          (f)  The Stockholder understands and acknowledges that Sabre, and
Travelocity.com are entering into the Merger Agreement in reliance upon the
Stockholder's execution and delivery of this Agreement.  The Stockholder
acknowledges that the irrevocable proxy set forth in Section 1(b) is granted
in consideration for the execution and delivery of the Merger Agreement by
Sabre and Travelocity.com.

          (g)  The Stockholder represents to Sabre, Travelocity Holdings and
Travelocity.com that it has no plan or intention to sell, exchange or
otherwise transfer ownership (including by derivative transactions such as an
equity swap which would have the economic effect of a transfer of ownership)
to Travelocity Holdings, Travelocity.com, Preview or any related person
(within the meaning of Treas. Reg. Section 1.368-1(e)(3)) with respect to any
of them or any agent of the foregoing, directly or indirectly (including
through partnerships or through third parties in connection with a plan to so
transfer ownership), of any shares of Travelocity.com Common Stock.

     4.   Covenants.   (a)  The Stockholder agrees with, and covenants to,
Sabre that it shall not (i) transfer (which term shall include, without
limitation, for the purpose of this Agreement, any sale, gift, pledge or
other disposition), or consent to any transfer of, any or all of the
Stockholder's Shares or any interest therein, except pursuant to the Merger;
(ii) enter into any contract, option or other agreement or understanding with

interest therein; (iii) grant any proxy, power of attorney or other
authorization in or with respect to such shares, except for this Agreement;
(iv) deposit such shares into a voting trust or enter into a voting agreement
or arrangement with respect to such shares; or (v) take any action prohibited
by Section 6.4 of the Merger Agreement.

          (b)  The Stockholder shall use its reasonable best efforts to take,
or cause to be taken, all necessary actions, and to do, or cause to be done
all things necessary, proper or advisable under this Agreement to consummate
the transactions contemplated by this Agreement, including, without
limitation, executing and delivering, or causing to be executed and delivered
(including by any record holder of any of the Stockholder's Shares), such
additional or further consents, documents and other instruments, as Sabre may
reasonably request, for the purpose of effectively carrying out the
transactions contemplated by this Agreement.

     5.   Representations and Warranties of Sabre.  Sabre represents and
warrants that this Agreement has been duly authorized, executed and delivered

                                      -4-

by, and constitutes a valid and binding agreement of, Sabre, enforceable
against Sabre in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws of general application respecting creditors' rights and by
general equitable principles.

     6.   Miscellaneous.

          (a)  Benefit and Assignment.  This Agreement shall be binding upon
each party hereto and such party's successors and assigns.  This Agreement
shall not be assignable by the Stockholder, but may be assigned by Sabre in
whole or in part to any direct or indirect wholly-owned subsidiary of Sabre,
provided that Sabre shall remain liable for any obligations so assigned.

          (b)  Headings.  The section headings herein are for convenience
only and shall not affect the construction hereof.

          (c)  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware without regard
to principles of conflicts of laws.  Any suit, action or proceeding seeking
to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby or
thereby may be brought in any federal or state court located in the State of
Delaware, and each of the parties hereby consents to the jurisdiction of such
courts (and of the appropriate appellate courts therefrom) in any such suit,
action or proceeding and irrevocably waives, to the fullest extent permitted
by law, any objection which it may now or hereafter have to the laying of the
venue of any such suit, action or proceeding in any such court or that any
such suit, action or proceeding which is brought in any such court has been
brought in an inconvenient forum.  Process in any such suit, action or
proceeding may be served on any party anywhere in the world, whether within
or without the jurisdiction of any such court.  Without limiting foregoing,
each party agrees that service of process on such party as provided in
Section 6(h) shall be deemed effective service of process on such party.

          (d)  Severability.  If any term, provision, covenant or restriction
of this Agreement is  held to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated.

          (e)  Enforcement of Agreement.  The parties agree that Sabre would
be irreparably damaged if for any reason the Stockholder failed, in breach of
its obligations hereunder, to perform any of its obligations under this
Agreement, and that Sabre would not have an adequate remedy at law for money
damages in such event.  Accordingly, Sabre shall be entitled to specific
performance and injunctive and other equitable relief to enforce the

                                      -5-

<PAGE>

performance of this Agreement by the Stockholder; and, if Sabre should
institute an action or proceeding seeking specific enforcement of the
provisions hereof, the Stockholder hereby waives the claim or defense that
Sabre has an adequate remedy at law and hereby agrees not to assert in any
such action or proceeding the claim or defense that such a remedy at law
exists.  The Stockholder further agrees to waive any requirements for the
securing or posting of any bond in connection with obtaining any such
equitable relief.  This provision is without prejudice to any other rights
that Sabre may have against the Stockholder for any failure to perform its
respective obligations under this Agreement.

          (f)  Amendments; Entire Agreement.  This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto.  This
Agreement contains the entire agreement between the parties hereto with
respect to the subject matter hereof and supersedes all prior and
contemporaneous agreements and understandings, oral or written, with respect
to such transactions.

          (g)  Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be an original, but all of which together
shall constitute one and the same Agreement.

conditions, to merge with and into Travelocity.com (the "Merger");

     WHEREAS, the Stockholder is a stockholder of Preview and has voting
power with respect to the number of shares (the "Shares") of common stock of
Preview (the "Preview Common Stock") set forth below the Stockholder's
signature hereto; and

     WHEREAS, in order to induce Sabre, Travelocity Holdings and
Travelocity.com to enter into the Merger Agreement and to provide reasonable

Shares upon the terms and subject to the conditions set forth below.

     NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements contained in this Agreement, and intending to be
legally bound hereby, the parties hereto agree as follows:

     1.   Voting of Shares; Grant of Irrevocable Proxy; Appointment of Proxy.

          (a)  The Stockholder agrees to vote all of its Shares of Preview
Common Stock, Shares of Preview Common Stock of any person controlled by the
Stockholder and any Shares of Preview Common Stock hereafter acquired by the
Stockholder or by any person controlled by the Stockholder (collectively, the
"Stockholder's Shares") as follows:

               (i)  At any meeting of Preview stockholders called to vote
upon the Merger or the Merger Agreement or at any adjournment thereof or in

<PAGE>

Stockholders' Meeting"), the Stockholder shall vote (or cause to be voted)
all of the Stockholder's Shares in favor of the Merger, the execution and
delivery by Preview of the Merger Agreement and the approval of the terms
thereof, and each of the other transactions contemplated by the Merger
Agreement.

               (ii) At any meeting of Preview stockholders or at any
adjournment thereof or in any other circumstances upon which their vote,
consent or other approval is sought, the Stockholder shall vote (or cause to
be voted) all of the Stockholder's Shares against (A) the approval of any
Acquisition Proposal or (B) any amendment of Preview's Certificate of
Incorporation or Bylaws or other proposal or transaction involving Preview or
any of its subsidiaries which amendment or other proposal or transaction
would in any manner impede, frustrate, prevent or nullify the Merger, the
Merger Agreement or any of the other transactions contemplated by the Merger
Agreement.

          (b)  The Stockholder hereby irrevocably grants to, and appoints,
Sabre and Donald J. Carty, Acting Chief Executive Officer of Sabre, and
Jeffrey M. Jackson, Chief Financial Officer of Sabre, in their respective
capacities as officers of Sabre, and any individual who shall hereafter
succeed to any such office of Sabre, and each of them individually, its proxy
and attorney-in-fact, with full power of substitution, for and in the name,
place and stead of the Stockholder, to vote upon and act with respect to all
of the Stockholder's Shares as set forth in subsections (a)(i) and (a)(ii) of
this Section 1.  The Stockholder represents that any proxies heretofore given
in respect of the Stockholder's Shares are not irrevocable, and that any such
proxies are hereby revoked.  The Stockholder hereby affirms that the
irrevocable proxy set forth in this Section 1(b) is given in connection with
the execution of the Merger Agreement, and that such irrevocable proxy is
given to secure the performance of the duties of the Stockholder under this
Agreement.  The Stockholder hereby further affirms that the irrevocable proxy

Stockholder hereby ratifies and confirms all that such irrevocable proxy may
lawfully do or cause to be done by virtue hereof.  Such irrevocable proxy is
executed and intended to be irrevocable in accordance with the provisions of
Section 212 of the Delaware General Corporation Law.  This proxy shall
survive the bankruptcy, merger, dissolution or liquidation of the
Stockholder.  In the event that the stockholders of Preview take action to
approve the Merger and the Merger Agreement by written consent in lieu of a
meeting of stockholders, the Stockholder will execute such consent and
provide a copy to Sabre.

     2.   Certain Events.  The Stockholder agrees that this Agreement and the
obligations hereunder shall attach to the Stockholder's Shares and shall be

law or otherwise, including without limitation, the Stockholder's successors
or assigns.  In the event of any stock split, stock dividend, merger,
reorganization, recapitalization or other change in the capital structure of
Preview affecting the Preview capital stock, or the acquisition of additional
shares of Preview capital stock or other voting securities of Preview by the
Stockholder, the number of the Stockholder's Shares subject to the terms of
this Agreement shall be adjusted appropriately and this Agreement and the
obligations hereunder shall attach to any additional shares of Preview
capital stock or other voting securities of Preview issued to or acquired by
the Stockholder.

     3.   Representation and Warranties of the Stockholder.  The Stockholder

application respecting creditors' rights and by general equitable principles.

any kind to which the Stockholder is a party or bound or to which the
Stockholder's Shares are subject.  If the Stockholder is married and the
Stockholder's Shares constitute community property, this Agreement has been

statute, law, rule or regulation applicable to the Stockholder or the
Stockholder's Shares.

by, and constitutes a valid and binding agreement of, Sabre, enforceable
against Sabre in accordance with its terms, except as enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws of general application respecting creditors' rights and by
general equitable principles.

     6.   Miscellaneous.

          (a)  Benefit and Assignment.  This Agreement shall be binding upon
each party hereto and such party's successors and assigns.  This Agreement

whole or in part to any direct or indirect wholly-owned subsidiary of Sabre,
provided that Sabre shall remain liable for any obligations so assigned.

          (b)  Headings.  The section headings herein are for convenience
only and shall not affect the construction hereof.

          (c)  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware without regard
to principles of conflicts of laws.  Any suit, action or proceeding seeking
to enforce any provision of, or based on any matter arising out of or in
connection with, this Agreement or the transactions contemplated hereby or
thereby may be brought in any federal or state court located in the State of
Delaware, and each of the parties hereby consents to the jurisdiction of such
courts (and of the appropriate appellate courts therefrom) in any such suit,
action or proceeding and irrevocably waives, to the fullest extent permitted
by law, any objection which it may now or hereafter have to the laying of the
venue of any such suit, action or proceeding in any such court or that any
such suit, action or proceeding which is brought in any such court has been
brought in an inconvenient forum.  Process in any such suit, action or
proceeding may be served on any party anywhere in the world, whether within
or without the jurisdiction of any such court.  Without limiting foregoing,
each party agrees that service of process on such party as provided in
Section 6(h) shall be deemed effective service of process on such party.

          (d)  Severability.  If any term, provision, covenant or restriction
of this Agreement is  held to be invalid, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions of this
Agreement shall remain in full force and effect and shall in no way be
affected, impaired or invalidated.

          (e)  Enforcement of Agreement.  The parties agree that Sabre would
be irreparably damaged if for any reason the Stockholder failed, in breach of
its obligations hereunder, to perform any of its obligations under this

damages in such event.  Accordingly, Sabre shall be entitled to specific
performance and injunctive and other equitable relief to enforce the

performance of this Agreement by the Stockholder; and, if Sabre should
institute an action or proceeding seeking specific enforcement of the
provisions hereof, the Stockholder hereby waives the claim or defense that
Sabre has an adequate remedy at law and hereby agrees not to assert in any
such action or proceeding the claim or defense that such a remedy at law
exists.  The Stockholder further agrees to waive any requirements for the
securing or posting of any bond in connection with obtaining any such
equitable relief.  This provision is without prejudice to any other rights
that Sabre may have against the Stockholder for any failure to perform its
respective obligations under this Agreement.

          (f)  Amendments; Entire Agreement.  This Agreement may not be
modified, amended, altered or supplemented, except upon the execution and
delivery of a written agreement executed by the parties hereto.  This
Agreement contains the entire agreement between the parties hereto with
respect to the subject matter hereof and supersedes all prior and
contemporaneous agreements and understandings, oral or written, with respect
to such transactions.

          (g)  Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be an original, but all of which together

     e-commerce category, with a combined registered membership base of 17
     million and more than $1 billion in projected 1999 travel sales.<F1>

     portals including America Online/Netscape, Yahoo!, Lycos, Go Network,

     for the Internet.


FORT WORTH, TX and SAN FRANCISCO, CA -Oct. 4, 1999 -Sabre Holdings
Corporation (NYSE: TSG) and Preview Travel, Inc. (NASDAQ: PTVL) today
announced the creation of a new company that combines Sabre's Travelocity.com
division with Preview Travel.  The transaction creates the clear leader in
online travel, a new company that will be known as Travelocity.com.  Sabre
will retain 70 percent ownership of the new company with the remaining 30
percent owned by Preview Travel stockholders.  The new company will benefit
from a new, five-year contract with America Online, Inc. that makes
Travelocity.com the exclusive reservations engine for all travel-related
services within the AOL service, AOL.COM, CompuServe, Digital City and
Netscape, and provides Travelocity.com with a share of specified travel-
related advertising revenues. In addition, Yahoo! Inc. has extended its
existing contract with Travelocity.com and has agreed to invest in the new
entity.

The merger creates a new powerhouse in the online travel market, the largest
retail e-commerce category, projected to grow from $7.8 billion in 1999 to
$32.1 billion by 2004.<F2>  The new, combined company will have more than
17 million registered memberships and more than eight million unique monthly
visitors -making it 50 percent larger than the next largest online travel
agency site.<F3>  Travelocity.com will have established distribution
relationships with America Online//Netscape, Yahoo!, Lycos, Go Network,
Excite, @Home and CompuServe, among other leading Internet sites.  Combined
travel sales for the two companies in the first half of 1999 totaled more
than $467 million. The new company is projected to be the third largest e-
commerce site after Amazon.com and eBay<F4>, and one of the top ten
travel agencies based on 1999 booking estimates.<F5>

At the close of the transaction, the combined business will be headquartered
in Fort Worth, Texas, with a significant operating presence in San Francisco.
Terrell B. Jones, president of Travelocity.com, will be the president and

<PAGE>

chief executive officer of the new company.  Donald J. Carty, chairman of
Sabre Inc., will serve as chairman of the board until a new Sabre chief
executive officer is named.  James Hornthal, founder and chairman of Preview
Travel, Inc., will serve as vice chairman.

"The new Travelocity.com will bring together the very best of Travelocity and
Preview Travel -two successful and talented organizations -to create an
unparalleled combination of content and innovative services to online
consumers," Terrell B. Jones said.  "We've long admired the Preview Travel
site for the experience it provides consumers.  Going forward, as the leader
in online travel, our focus will continue to be on providing the best
shopping opportunities and customer support available anywhere -online or
offline."

"Bringing together the innovative technology solutions of Sabre's
Travelocity.com with Preview Travel's effective integration of content,
community, commerce and world-class customer service will benefit our
customers and our partners," James Hornthal said.  "We expect the additional
scale that we will achieve throughout the enterprise to translate into long-
term consumer and stockholder value."

America Online Agreement
At close of the merger transaction between Travelocity and Preview Travel,
Travelocity.com will have a new five-year agreement with America Online.
Under the new deal, the new Travelocity.com will be the exclusive
reservations engine for all travel-related services within the AOL service,
AOL.COM,  CompuServe, Digital City and Netscape. The AOL agreement will allow
users to access the same set of travel reservations services from each of
these AOL brands, providing a consistent and seamless experience from
multiple access points.  The agreement also calls for a unique revenue
sharing structure designed to reward both companies based on the success of
their trend-setting partnership.  AOL will share in commissions on travel
sales and Travelocity.com will share in advertising revenue.

Yahoo! Agreement
Sabre also announced that it has agreed on terms with Yahoo! Inc. for an
extension of the existing contract, strengthening the relationship between
Travelocity.com and Yahoo! Travel, Yahoo!'s comprehensive resource for
researching, planning and booking travel.  The agreement will be contributed
to the new Travelocity.com as part of the merger. Yahoo! has also agreed to
make a minority investment in the new company, demonstrating additional
support of the ongoing relationship with Travelocity.com.

Merger Structure
Sabre will contribute the assets of Travelocity.com plus $50 million in cash
in exchange for 70 percent ownership in the new company, formed as a Delaware
limited partnership.  Current Preview Travel stockholders will hold 30

                                      -2-

<PAGE>

percent of the combined entity through a new corporate entity,
Travelocity.com Inc.  At the close of this transaction, Preview Travel shares
will convert 1:1 into shares of the new company, and Travelocity.com Inc.
will trade under the symbol TVLY on the NASDAQ National Market System.

The merger has been approved by both Sabre and Preview Travel boards of
directors, and is expected to close in first quarter 2000.  The transaction
is subject to regulatory approval, customary closing conditions and requires
approval by Preview Travel's stockholders.

Preview Travel was advised by Hambrecht and Quist on the transaction, while
Sabre was advised by Goldman Sachs & Co.

Shareholder Benefits
"We have been committed to unlocking the value of Travelocity.com for Sabre's
shareholders," said Donald Carty, chairman of Sabre Inc.  "Through the new
ownership structure, we've created a pure Internet play in which our
shareholders will own a majority stake of the third largest e-commerce site.
In addition, this transaction provides Travelocity.com with access to
Internet currency, and at the same time preserves the product development
synergies that exist between Travelocity.com and Sabre."

Once the two sites are fully integrated, the new Travelocity.com will use the
Sabre computer reservations system, strengthening Sabre as the largest
processor of travel transactions on the Internet and the leader in all other
channels of travel distribution. Sabre will consolidate the financial results
of the new company into its own financial reporting and will continue to
trade under the symbol TSG on the New York Stock Exchange.  AMR's majority-
ownership of Sabre is unaffected by this transaction.

"Consolidation in growing markets is inevitable.  The drive to achieve global
scale is incredibly compelling for us and our strategic marketing partners,"
said Chris Clouser, president and chief executive officer of Preview Travel,
Inc.  "By combining resources with Travelocity, we are able to help write the
next chapter in online travel.  We expect our clear leadership position will
pay important dividends, now and in the future, for our customers, employees
and shareholders."
