                                                                  EXECUTION COPY

                                 FIRST AMENDMENT

                         AMENDED AND RESTATED AGREEMENT

                       FOR CRS ACCESS AND RELATED SERVICES

This FIRST AMENDMENT TO THE AMENDED AND RESTATED AGREEMENT FOR CRS ACCESS AND
RELATED SERVICES (this "Amendment"), dated as of December 13, 2002 ("Amendment
Effective Date"), is between Worldspan, L.P., a Delaware limited partnership,
("Worldspan") and Orbitz, LLC, a Delaware limited liability company ("Orbitz").

WHEREAS, Orbitz and Worldspan entered into that certain Amended and Restated
Agreement for CRS Access and Related Services dated as of November 1, 2001 (the
"Agreement"); and

WHEREAS, Orbitz and Worldspan desire to amend the Agreement as set forth herein;

NOW, THEREFORE, Orbitz and Worldspan hereby agree to amend the Agreement as
follows:

1.   The "WHEREAS" clauses are hereby restated in their entirety to provide as
follows:

     "WHEREAS, Orbitz operates various businesses offering travel-related
     products and services to the end-user community as well as to the travel
     industry;

     WHEREAS, among its other businesses, Orbitz provides travel end-users with
     a consumer-oriented Internet travel portal under the "Orbitz.com" domain
     name through which they can complete the booking of air travel, hotel
     accommodations, car rentals, and other travel products (such portal, and
     any related, private labeled or successor Internet sites, such as "Orbitz
     for Business," that are controlled by Orbitz, the "Orbitz Website");

     WHEREAS, Orbitz also provides or may in the future provide to travel
     professionals in the travel industry certain travel-related products and
     services that are not oriented to a consumer end-user and that do not use
     or access the Orbitz Website, including, without limitation, travel agent
     desktop tools and other products and services intended for use by travel
     agents, corporate travel managers and other travel professionals,
     ("Industry Services");

     WHEREAS, in connection with its Orbitz Website business, Orbitz has
     selected Worldspan to provide access to and use of the computer
     reservations systems operated by Worldspan as provided in this Agreement,
     and has selected other

<Page>

     companies to provide the booking engine, fulfillment services, customer
     service center, and other products and services required by Orbitz for the
     Orbitz Website;

     WHEREAS, it is the intent of the parties that this Agreement shall govern
     the provision of such services to Orbitz and the use of the Worldspan
     System, but only in connection with the Orbitz Website business, and not in
     connection with Industry Services or any other business that Orbitz
     operates or may operate."

2.   Section 2.1 is hereby restated in its entirety to provide as follows:

     "2.1 CRS ACCESS. During the Term of this Agreement, Worldspan will provide
     Orbitz, as well as the Booking Engine Provider, the Customer Service Center
     Provider, the Fulfillment Provider, ITA and any other third parties that
     may be engaged by Orbitz to provide products or services for the operation
     of the Orbitz Website and that require such access in order to provide
     those products or services, with access to the Worldspan System (including,
     without limitation, Availability Data Services) for the purposes of the
     operation of the Orbitz Website and in accordance with the provisions of
     this Agreement. Orbitz is authorized to access Availability Data Services,
     for the purposes of processing any Supplier Link Segments as set forth in
     Sections 2.10 and 4.7 herein and as otherwise in a manner that is
     consistent with this Agreement."

3.   A new Section 2.10 is hereby added to the Agreement to provide as follows:

     "2.10 AUTHORIZATION TO USE THE AVAILABILITY DATA SERVICES FOR SUPPLIER LINK
     SEGMENTS.

     (a)    During the Term of this Agreement and subject to Section 4.7,
     Worldspan will provide Orbitz, as well as the Booking Engine Provider, the
     Customer Service Center Provider, the Fulfillment Provider, ITA and any
     other third parties that may be engaged by Orbitz to provide products or
     services for the operation of the Orbitz Website, access to the
     Availability Data Services in connection with an Orbitz offering made to
     any User using the Orbitz Website; provided, however, that Orbitz is not
     authorized to access the Worldspan System or the Availability Data Services
     in connection with any contract or agreement with a Worldspan Customer for
     the purpose of providing such Worldspan Customer access to the Orbitz
     Website, unless Orbitz has obtained Worldspan's prior written consent. For
     the avoidance of doubt, the license in the previous sentence does not
     authorize the use or remarketing of Availability Data Services other than
     for the Orbitz Website.

     (b)    Orbitz may terminate use of the Availability Data Services upon 60
     days' prior written notice to Worldspan. Worldspan may terminate provision
     of the Availability Data Services to or on behalf of Orbitz upon the
     earlier of (i) termination of use of such services by Orbitz or ITA, or
     (ii) the end of any period specified in an Orbitz notice electing to use
     such services."

4.   Section 3.2 is hereby restated in its entirety to provide as follows:

     "USE OF WORLDSPAN SYSTEM. Orbitz has incorporated the Worldspan System into
     the Orbitz Website and will use reasonable business efforts to encourage
     Users to book travel by means of the Orbitz Website so as to generate Net
     Segments booked through the Worldspan System. For the avoidance of doubt,
     the foregoing sentence shall not impair or restrict Orbitz' right to
     encourage Users to book travel through Supplier Link Segments, provided
     that such bookings are consistent with Orbitz' obligations under this
     Agreement.

     (a)    Effective January 1, 2003, Orbitz agrees (i) to cause not less than
     one hundred percent (100%) of all Non-Direct Connect Car Segments and (ii)
     to cause not less than one hundred percent (100%) of all Airline Non-Direct
     Connect Segments booked on behalf of all Users, including Corporate Users,
     by means of the Orbitz Website to be booked through the Worldspan System.

     (b)    In the event the number of Adjusted Quarterly Net Segments booked
     through the Worldspan System falls below the Applicable Quarterly Minimum
     set forth below in any calendar quarter commencing with the calendar
     quarter beginning January 1, 2003, Orbitz shall pay Worldspan the Minimum
     Segment Fee set forth in Section 4.8(a) in accordance with the payment
     terms set forth therein.

     For purposes of the foregoing calculation, the number of Net Segments (if
     any) by which the Applicable Quarterly Minimum is exceeded in a particular
     calendar quarter shall be carried forward and applied to the next
     subsequent calendar quarter in such calendar year. The number of Net
     Segments in a particular calendar quarter plus the number of excess Net
     Segments, if any, carried forward from the previous calendar quarter(s) in
     such calendar year shall be referred to as the "Adjusted Quarterly Net
     Segments." With respect to the calendar quarter ending March 31, the
     Adjusted Quarterly Minimum shall equal the number of actual Net Segments
     booked through the Worldspan System during such calendar quarter. For
     illustration, if the number of Net Segments achieved in the calendar
     quarter ending March 31 is [***], thus exceeding the Applicable Quarterly
     Minimum for such quarter by 1,000,000, then the Adjusted Quarterly Net
     Segments for the quarter ending June 30 shall be the number of Net Segments

     actually achieved in such quarter, plus 1,000,000, and to the extent this
     Adjusted Quarterly Net Segments value exceeds the Applicable Quarterly
     Minimum of [***] Net Segments for the quarter ending June 30, such excess
     shall be applied toward the Adjusted Quarterly Net Segment calculation for
     the quarter ending September 30. No such excess shall be carried forward
     into a subsequent calendar year or backwards to a previous calendar year.

     Notwithstanding the foregoing, no Minimum Segment Fee shall be payable by
     Orbitz for a given calendar quarter, even if the total number of Adjusted
     Net Segments in such calendar quarter does not equal or exceed the
     Applicable Quarterly Minimum, if, either (i) Orbitz has not booked any
     Airline Direct Connect Segments or Direct Connect Car Segments in such
     calendar quarter and processes 100% of Orbitz' air and car bookings through
     Worldspan, or (ii) (A) a Safe Harbor Event has occurred, (B) Orbitz has
     provided notice to Worldspan of such Safe Harbor Event within 20 days
     following its occurrence, (C) Orbitz has not provided notice to Worldspan
     of a prior Safe Harbor Event during such calendar year, and (D) beginning
     on the fifth business day following Orbitz' provision of such notice to
     Worldspan, for the remainder of the calendar quarter and until the end of
     the calendar year (or such earlier time as Orbitz declares, by written
     notice to Worldspan, the conclusion of the Safe Harbor Event), Orbitz has
     eliminated all Airline Direct Connect Segments and all Direct Connect Car
     Segments and processes 100% of Orbitz' air and car bookings through
     Worldspan.

     (c)    Orbitz agrees that it will not directly or indirectly acquire or use
     any products or services from a CRS other than Worldspan to support or use
     with the Orbitz Website for Airline Direct Connect Customers or Direct
     Connect Car Customers. Notwithstanding the foregoing, if Worldspan
     eliminates a product or service used by Orbitz and does not replace it with
     a comparable product or service on commercial terms no less favorable to
     Orbitz, Orbitz may obtain a replacement product or service from another
     CRS. Orbitz will use reasonable business efforts to prevent unauthorized or
     improper use of or access to the Worldspan System and to ensure that its
     employees, agents, third parties that may be engaged by Orbitz to provide
     products or services for the operation of the Orbitz Website, and Users
     access and use the Worldspan System in compliance with all reasonable
     instructions provided by Worldspan, including the following:

     (i)    The Worldspan System may not be used to transmit personal messages,
            make speculative or improper bookings, train anyone other than
            Orbitz employees, agents, or Users, or publish or disseminate a
            compilation of air carrier service or other information.

            Proper and permitted use of the Worldspan System, including data and
            services provided through such system, consists of (i) using the

            Availability Data Services with respect to one or more Airline
            Direct Connect Customers for purposes of and consistent with this
            Agreement, (ii) making proper and legitimate reservations and
            booking Segments, (iii) issuing travel documents related to such
            Segments, and (iv) performing normal accounting and record keeping
            functions, all of the foregoing only in accordance with rules and
            regulations issued from time to time by Worldspan and subject to the
            terms and conditions of this Agreement. Improper use of the
            Worldspan System includes, without limitation, making speculative or
            improper bookings, reserving space in anticipation of demand, and
            improper creation or modification of records.

            Orbitz shall not use or access the Worldspan System, including data
            and services provided through such system, without Worldspan's prior
            written consent (i) to make bookings on any CRS other than
            Worldspan, (ii) to make bookings on any airline or other reservation
            system (except as permitted in Section 2.10), (iii) to develop or
            test software applications, including without limitation, booking
            engines, corporate booking programs, FLIFO-type products, fares and
            pricing tools, caching products, travel agent desktop tools, and
            airline hosting applications (which such prior written consent shall
            not be unreasonably withheld), or (iv) in any other manner that is
            not expressly permitted hereunder or is unauthorized or improper.

            Orbitz' employees, agents, and Users may not enter passive bookings
            (e.g., GC, HK, MK or BK codes) into the Worldspan System when no
            corresponding space has been reserved with the corresponding travel
            supplier's internal reservations system. Any passive bookings will
            be removed from the Worldspan System if the corresponding space is
            cancelled.

     (v)    The material and information supplied by Worldspan will not be
            manipulated in a manner that would lead to inaccurate, misleading,
            or discriminatory presentation of information to consumers.

            Orbitz will promptly report to Worldspan any incidents of suspected
            unauthorized access to or use of the Worldspan System and will use
            reasonable commercial efforts to curtail access to or use of the
            Worldspan System by any User upon Worldspan's reasonable request.

            Other than as described in Section 2.10, Section 4.7(c), oras may be
            mutually agreed in writing by the parties, Orbitz shall not,
            effective January 1, 2003, use the Worldspan System to service
            Supplier Link Segments, including but not limited to, such services
            as PNR storage, queues, profiles, fares and pricing systems, Auto
            Re-Issues or Rapid Re-Price. Also, Orbitz shall not use the
            Worldspan System to search for fares,

            rates, schedules or itineraries that involve Airline Direct Connect
            Segments."

5.   Section 4.4 of the Agreement is hereby restated in its entirety to provide
as follows:

     "4.4 [Intentionally Deleted]"

6.   A new Section 4.7 is hereby added to the Agreement to provide as follows:

     "4.7 SUPPLIER LINK CONDITIONS AND PROCESSING FEE.

     (a)    Effective January 1, 2003, within 90 days after the Implementation
     Date for an Airline Direct Connect Customer, Orbitz shall discontinue all
     access, either directly or through ITA, to the Worldspan System with
     respect to Supplier Link Segments for such Airline Direct Connect Customer.
     In the event Orbitz or ITA, acting at the direction and on behalf of
     Orbitz, as the case may be, continues to generate DIR INVQ Messages for any
     Airline Direct Connect Customer more than 90 days after the Implementation
     Date, Orbitz shall pay Worldspan a monthly processing fee in accordance
     with Table 1 set forth on Schedule E for each such month.

     (b)    Orbitz will use its good faith efforts to keep Worldspan's Contract
     Manager apprised of the expected Implementation Date for each Airline
     Direct Connect Customer and each Direct Connect Car Customer no less than
     30 days prior to the anticipated Implementation Date, and to coordinate
     with the Worldspan Contract Manager during such 30 day period. Following
     the actual Implementation Date for each Airline Direct Connect Customer and
     each Direct Connect Car Customer, Orbitz will provide prompt and
     simultaneous notice thereof to Worldspan's Contract Manager and the carrier
     or car rental company, as applicable. No later than 90 days after the
     Implementation Date of an Airline Direct Connect Customer, Orbitz will
     reduce the total DIR INVQ Messages sent to Worldspan on Orbitz' behalf by
     the amount shown on Table 2 set forth on Schedule E for each named carrier.
     Upon implementation of all of the Core Airline Customers as Airline Direct
     Connect Customers, Orbitz shall be permitted no more than a total of 5 DIR
     INVQ Messages per second to supply the availability cache for all carriers
     other than the Airline Direct Connect Customers.

     (c)    Notwithstanding Sections 4.7(a) and (b), Orbitz shall discontinue
     all access, either directly or through ITA, to the Worldspan System with
     respect to Supplier Link Segments for American Airlines no later than
     January 31, 2003 and with respect to Supplier Link Segments for Continental
     Airlines no later than January 1, 2003. In the event Orbitz or ITA, acting
     at the direction and on behalf of Orbitz, as the case may be continues to
     generate DIR INVQ Messages for American Airlines or Continental Airlines
     after January 1, 2003, Orbitz shall pay Worldspan a monthly processing fee
     in accordance with Table 1 set forth on Schedule E for each month of usage.

     A new Section 4.8 is hereby added to the Agreement to provide as follows:

     "4.8 MINIMUM SEGMENT FEES. Commencing January 1, 2003 and through the
     balance of the Term of this Agreement, in the event Orbitz does not satisfy
     the minimum Net Segments or minimum Net Car Segments requirements described
     in subsection (a) or (b) below, Orbitz will pay Worldspan a fee ("Minimum
     Segment Fee") calculated as follows:

     (a)    In the event Orbitz does not satisfy the requirements of Section
     3.2(b) with respect to a particular calendar quarter, then, in addition to
     all payments under this Agreement, Orbitz shall pay to Worldspan a Minimum
     Segment Fee equal to the difference between the Applicable Quarterly
     Minimum for such calendar quarter and the Adjusted Quarterly Net Segments
     applicable to such calendar quarter, multiplied by $1.78.

     (b)    In the event Orbitz books a Direct Connect Car Segment in a
     particular calendar quarter through a Direct Connect Car Customer and does
     not, during such calendar quarter, book at least the minimum Net Car
     Segments set forth below through the Worldspan System ("Applicable
     Quarterly Minimum Net Car Segments"), then, in addition to all payments
     under this Agreement, Orbitz shall pay to Worldspan a Minimum Segment Fee
     equal to the difference between the Applicable Quarterly Minimum Net Car
     Segments set forth below and the Adjusted Quarterly Net Car Segments (as
     defined below) for such calendar quarter, multiplied by $1.78.

     For purposes of the foregoing calculation, the number of Net Car Segments
     (if any) by which the Applicable Quarterly Minimum Net Car Segments for a
     particular calendar quarter is exceeded shall be carried forward and
     applied to the next subsequent quarter in such calendar year. The number of
     Net Car Segments in a particular calendar quarter plus the number of excess
     Net Car Segments carried forward, if any, from the previous calendar
     quarter(s) in such calendar year shall be referred to as the "Adjusted
     Quarterly Net Car Segments." With respect to the calendar quarter ending
     March 31, the Adjusted Quarterly Net Car Segments shall equal the number of
     actual Net Car Segments booked through the Worldspan System during such
     calendar year.

     For illustration, if the number of Net Car Segments achieved in the
     calendar quarter ending March 31, 2003 is [***], thus exceeding the
     Applicable Quarterly Minimum Net Car Segments for such quarter by 100,000,
     then the Adjusted Quarterly Net Car Segments for the quarter ending June
     30, 2003 shall be the number of Net Car Segments actually achieved in such
     quarter, plus 100,000, and to the extent this Adjusted Quarterly Net Car
     Segments value exceeds the Applicable Quarterly Minimum Net Car Segments of
     [***] for the quarter ending

     June 30, 2003, such excess shall be applied toward the Adjusted Quarterly
     Net Car Segment calculation for the quarter ending September 30, 2003. No
     such excess shall be carried forward into a subsequent calendar year or
     backward into a previous calendar year.

     Notwithstanding the foregoing, no Minimum Segment Fee shall be payable by
     Orbitz, even if the total number of Adjusted Quarterly Net Car Segments for
     a given calendar quarter does not equal or exceed the value set forth
     below, if, (i) a Safe Harbor Event has occurred, (ii) Orbitz has provided
     notice to Worldspan of such Safe Harbor Event within 20 days following its
     occurrence, (iii) Orbitz has not provided notice to Worldspan of a prior
     Safe Harbor Event during such calendar year, and (iv) beginning on the
     fifth business day following Orbitz' provision of such notice to Worldspan,
     for the remainder of the calendar quarter and until the end of the calendar
     year (or such earlier time as Orbitz declares, by written notice to
     Worldspan, the conclusion of the Safe Harbor Event), Orbitz has eliminated
     all Direct Connect Car Segments and processes 100% of Orbitz' car bookings
     through Worldspan.

     (g)    If this Agreement terminates in the middle of a calendar quarter,
     then (A) the Minimum Segment Fee, if applicable, for the final quarter of
     this Agreement shall be prorated on a per diem basis based on the
     Applicable Quarterly Minimum requirement for Net Segments and the
     Applicable Quarterly Minimum Net Car Segment requirement for Net Car
     Segments for the quarter in which this Agreement terminates and (B) if the
     number of Net Segments or Net Car Segments, as the case may be, achieved
     during such calendar year exceeds the sum of the Applicable Quarterly
     Minimums or Applicable Quarterly Minimum Net Car Segments, respectively,
     for any prior calendar quarters in such calendar year PLUS the pro rated
     requirement calculated pursuant to (A) above, then any Minimum Net Segment
     Fees paid by Orbitz with respect to such calendar year shall be reimbursed
     by Worldspan to Orbitz within 30 days following the termination of the
     Agreement.

     (h)    Notwithstanding the foregoing, no Minimum Segment Fee shall apply in
     any calendar year in which Orbitz terminates the Agreement in accordance
     with Section 7.1, 7.2, 7.3, 7.4, 7.5 or 9.1."

8.   Section 9.1 is amended by adding the following to the end thereof:

     "Notwithstanding the foregoing, in the event (x) Orbitz merges,
     consolidates, or otherwise combines with a CRS; or (y) substantially all of
     the operating assets of Orbitz are acquired by a CRS; Orbitz shall not
     assign or transfer this Agreement or any of its rights or obligations under
     this Agreement, without the prior written consent of Worldspan. In the
     event Orbitz requests a consent in connection with a proposed transaction
     described in (x) or (y) above, and Worldspan fails to provide such consent
     within 10 days of receipt of the request, then such consent shall be deemed
     to have been denied, and either Orbitz or Worldspan shall have the right to
     terminate this Agreement, by notice to the other, with such termination not
     to take effect until the consummation of such proposed transaction.

9.   Section 9.15 is hereby restated in its entirety to provide as follows:

     "9.15 ORBITZ AUDIT RIGHTS. During the Term of this Agreement and for one
     (1) year thereafter, Worldspan agrees to keep all usual and proper records
     and books of account relating to the products and services provided by
     Worldspan and operation of the Worldspan System pursuant this Agreement.
     Once each calendar year during the Term of the Agreement, and upon twenty
     (20) days prior written notice to Worldspan, Orbitz may have an auditor
     inspect the records and other information collected, generated or
     maintained by Worldspan arising out of or in connection with the provision
     of the services pursuant to this Agreement, during Worldspan 's normal
     business hours, for the sole purpose of determining the accuracy of the
     charges, expenses, costs, fees, service levels, and otherwise determining
     Worldspan's compliance with this Agreement. Orbitz shall pay for all the
     costs of such inspection, including all reports and any other information
     supplied. Information disclosed to Orbitz or to its auditing representative
     in the course of such inspection shall be subject to the confidentiality
     requirements of this Agreement and may not be used for any purpose
     whatsoever other than the determination of compliance with Worldspan's
     obligations under this Agreement."

10.  A new Section 9.16 is hereby added to the Agreement to provide as follows:

     "9.16 WORLDSPAN'S AUDIT RIGHTS. During the Term of this Agreement and for
     one (1) year thereafter, Orbitz agrees to keep all usual and proper records
     and books of account relating to Net Segments and Supplier Link Segments
     generated by Orbitz, the operation of the Orbitz Website, and other
     activities and matters pursuant this Agreement. Once each calendar year
     during the Term of the Agreement, and upon twenty (20) business days prior
     written notice to Orbitz, Worldspan may have an auditor inspect the records
     and other information collected, generated or maintained by Orbitz arising
     out of or in connection with this Agreement, during Orbitz' normal business
     hours, for the sole purpose of determining the accuracy of the calculation
     of Net Segments and Supplier Link Segments, and otherwise determining
     Orbitz' compliance with this Agreement. Worldspan shall pay for all of the
     costs of such inspection, including all reports and any other information
     supplied. Information disclosed to Worldspan or to its auditing
     representative in the course of such inspection shall be subject to the
     confidentiality requirements of this Agreement and may not be used for any
     purpose whatsoever other than the determination of compliance with Orbitz's
     obligations under this Agreement."

11.  A new Section 9.17 is hereby added to the Agreement to provide as follows:

     "9.17 NO CONFLICT. (a) Worldspan represents and warrants to Orbitz that
     neither the execution and delivery of this Agreement nor the performance by
     Worldspan of its obligations hereunder does or will constitute a breach,
     default, or violation of any of Worldspan's obligations under any contract,
     agreement, license, consent or permit to which it is a party.

                                       10
<Page>

     (b)    Except as provided in the next sentence, Orbitz represents and
     warrants to Worldspan that neither the execution and delivery of this
     Agreement nor the performance by Orbitz of its obligations hereunder does
     or will constitute a breach, default, or violation of any of Orbitz's
     obligations under any contract, agreement, license, consent or permit to
     which it is a party. In light of the complaint filed by Amadeus Global
     Travel Distribution, S.A. and Amadeus s.a.s. (collectively, "Amadeus")
     against Orbitz in the United States District Court for the District of
     Delaware, Orbitz represents and warrants, to the best of its knowledge and
     belief, that neither the execution and delivery of this Agreement nor the
     performance by Orbitz of its obligations hereunder does or will constitute
     a breach, default, or violation of any of Orbitz's obligations to Amadeus
     under its agreements with ITA Software, Inc."

12.  The definition of "Airline Direct Connect Segment" in Schedule A of the
     Agreement is hereby amended to provide as follows:

     "Airline Direct Connect Segment" means each nonstop or direct airline
     flight booked by means of the Orbitz Website with an Airline Direct Connect
     Customer using that carrier's internal airline reservation system and not
     using a CRS or global distribution system."

     The definition of "CRS" in Schedule A of the Agreement is hereby amended to
     provide as follows:

     "CRS" means a computer reservation system that is operated by Worldspan,
     Sabre, Galileo, Amadeus, Abacus, Infini, Axxess, Pegasus, Wizcom or by any
     other company that operates such a system in order to provide information
     about the schedules, fares, rates, and availability of the products and
     services of travel suppliers and to enable the making of reservations and
     the issuance of tickets for such products and services, but excluding a
     travel supplier's own system (including where a travel supplier's own
     system is, or is a partition within, a computer system that would otherwise
     be a CRS hereunder) to the extent such travel supplier's own systems are
     used to provide information and enable the making of reservations and the
     issuance of tickets for that particular travel supplier. As examples, the
     internal system of Lufthansa for the issuance of airline tickets and the
     internal system of Avis for the making of car reservations would not be
     considered CRSs even if such systems were maintained by Amadeus and Wizcom,
     respectively, within the computer reservation systems operated by Amadeus
     and Wizcom.

13.  Schedule A of the Agreement is hereby amended by adding the following

Orbitz, or ITA acting at the direction of and on behalf of Orbitz, as the case
may be, may forward 22 DIR INVQ Messages per second ("Allowable Messages"),
subject to reduction in accordance with the following:

     (i)    Orbitz agrees that it will cause ITA to make such changes and
            modifications as necessary in order to reduce the number of DIR INVQ
            Messages per second by 4 prior to January 1, 2003, subject to
            Worldspan providing such cooperation and assistance reasonably
            necessary for ITA and Orbitz to achieve the foregoing.

     (ii)   In addition, as each of the following air carriers (i) becomes an
            Airline Direct Connect Customer, (ii) ceases participation in the
            Worldspan System at the Airline Source level, or (iii) ceases

            TO WORLDSPAN THE RELEVANT PROCESSING FEE FOR A NAMED CARRIER AS SET
            FORTH IN TABLE 1 ABOVE, NO REDUCTION IN DIR INVQ MESSAGES FOR SUCH
            CARRIER SHALL BE REQUIRED.

Notwithstanding the foregoing, in the event any Core Airline Direct Connect
Customer merges with another Core Airline Direct Connect Customer, then the
number of DIR INVQ Messages set forth in Table 2 shall be subject to adjustment
by Worldspan but in no event will the adjustment be more than the sum of the
number of DIR INVQ Messages per second in Table 2 for each carrier involved in
the merger.

WORLDSPAN AND ORBITZ CONFIRM TECHNOLOGY PARTNERSHIP

ATLANTA, CHICAGO, XXXXXXX, 2002--Worldspan and Orbitz today announced a new
long-term technology partnership agreement to support Orbitz' domestic airline
bookings. Both parties confirmed that Worldspan remains Orbitz' preferred
technology partner and they have finalized their long-term contract that
includes an agreement for Orbitz to purchase a broad range of technology
services. This relationship is an important joint step in reengineering the

Worldspan, which has been instrumental in changing the industry's dynamics, will
continue to supply Orbitz with the technology needed to maintain Availability
Processing, Flight Information (FLIFO) via XML and booking for international,
interline, and paper tickets and for all other airlines who do not choose to
subscribe to the Supplier Link booking service.

"Worldspan remains committed to the efficiency of the industry," said Paul
Blackney, Worldspan's president and chief executive officer. "Our partnership
with Orbitz is a strong commitment by both companies to do what it takes to
provide valuable innovations to the traveling public. We pride ourselves on our
inventive technology, innovative solutions and customer support and look forward
to continuing to be Orbitz' technology partner."

"Worldspan's reliability and innovation has been a contributing factor to
Orbitz's success," said Jeff Katz, Orbitz President and CEO. "We look forward to
continuing our successful technology partnership as Orbitz grows its business as
a leader in online travel."
