                             Exhibit D - Fees/Costs

1.   Payment:

     Expedia will pay TRX on a Mid/Back Office and Front Office Fee basis in
accordance with the prices set forth below:

     (1)  "Mid/Back Office Fee" as used herein shall include payment for the
following services: ticketing, refunds, voids, exchanges, support for LTA (lost
ticket applications) reconciliation, debit memo processing, process and ticket
distribution, ARC processing, record keeping and accounting, quality control
processes (CoRRe, CRS scripts, all automated/robotic processes), delivery
emails, schedule change processing and emails, survey emails, system planning
and maintenance and reporting. The parties may mutually agree in writing to
include other services within this definition of Mid/Back Office Fee. The
parties agree that the Mid/Back Office Fee shall be [*] for the term of this
Agreement.

     (2)  "Front Office Fee" as used herein shall include payment for the
following services: emails answered ("Emails"), Calls, reporting, system
planning and maintenance, resolution and escalation for pre-trip and en-route
customer service issues, and post-travel customer service research and issue
resolution ("CRD"). The parties may mutually agree to include other services
within this definition of Front Office Fee. The parties agree that the Front
Office Fee shall be based on the formula set forth in Section (3)(b), (3)(c),
and (3)(d) below.

     (3)  The monthly payment will be determined as follows:

          (a)  TRX will multiply the number of Tickets issued per month ("Net
     Voided Tickets") times the Mid/Back Office Fee to calculate the price per
     month. (For example, if 100,000 Tickets are sold during a particular month,
     payment will be 100,000 multiplied by [*] or [*]).

          (b)  Expedia will pay TRX for the Services in accordance with the
     prices set forth below (based on an assumption of [*] minutes per telephone
     Call which includes talk time, hold time and after Call work, defined
     hereinafter as the "Call Standard"). In the case where actual telephone
     Call handling durations vary [*] above the Call Standard and TRX can
     substantiate claims in writing to Expedia's reasonable satisfaction that
     material changes to Expedia's Call handling tools or procedures caused said
     increase in Call handling durations for any two (2) consecutive months,
     Expedia has thirty (30) days from substantiation of such claims to correct
     and/or change said Expedia Call handling tools or procedures in an effort
     to reduce Call handling durations to be within [*] of the Call Standard. In
     the event Expedia does not assist in reducing Call durations to be within
     [*] of the Call Standard, TRX has the right to demand that the parties
     negotiate in good faith to mutually agree upon a new per Call price which
     will be paid retroactively to the first month of the increased Call
     handling duration. In the case where actual Call

[*] The redacted portion, indicated by this symbol, is the subject of a
confidential treatment request and has been filed separately with the Securities
and Exchange Commission.

<PAGE>

               handling durations vary [*] below the Call Standard for any three
               (3) consecutive months, Expedia has the right to demand that the
               parties negotiate in good faith to mutually agree upon a new per
               Call price to be paid retroactively to the first month of the
               decreased Call handling duration. TRX will multiply the number of
               Calls answered per month times [*] to calculate the price per
               month. (For example, if there are 50,000 inbound Calls answered
               during a particular month, payment will be 50,000 multiplied by
               [*] or [*]).

                    (c) TRX will multiply the number of Emails per month by [*]
               to calculate the price per month. (For example, if there are
               50,000 Emails during a particular month, payment will be 50,000
               multiplied by [*] or [*]). TRX agrees to answer Emails at
               discounted pricing based on volume. The parties agree that
               Expedia will pay TRX [*] for each Email in excess of [*] Emails
               in a calendar month.

                    (d) TRX will multiply the number of CRD Cases Completed
               (defined below) per month by [*] to calculate the price per
               month. (For example, if there are 1,000 CRD during a particular
               month, payment will be 1,000 multiplied by [*] or [*]). For the
               purpose of clarity, "CRD Cases Completed" refers to the number of
               unique customer service cases which require off-line follow-up
               research with a vendor and/or Expedia and which shall include
               verbal and written follow-up communication to the customer
               (except in such cases that vendor and/or EI will conduct such
               follow-up) and adequate documentation entered into the [*]
               system.

                    (e) In addition, TRX agrees to consolidate Expedia's support
               activities to its Atlanta, GA, Parkersburg, WV, and Orangeburg,
               SC facilities. Once accomplished, Expedia agrees to pay TRX the
               monthly costs of internet access bandwidth to its Parkersburg, WV
               and Orangeburg, SC customer contact centers for each month that
               TRX's total [*] utilization rate exceeds [*] of Calls answered.
               For the purpose of clarity, it is estimated that total monthly
               costs for internet bandwidth to both centers is [*].
               Notwithstanding the foregoing, in no event will Expedia's
               commitment to this cost exceed [*] per month. TRX will invoice
               Expedia for actual bandwidth costs (not to exceed [*] per month)
               for each month that TRX's total [*] utilization rate exceeds [*]
               of Calls answered.

                    (f) Each month, TRX will calculate the "Schedule Change
               Ratio" by dividing the actual number of outbound schedule change
               calls by the number of Calls. If the Schedule Change Ratio
               exceeds [*], Expedia shall pay TRX an additional amount which
               will be determined by multiplying (i) the difference of the
               number of outbound schedule change less the Target Schedule
               Change Calls (defined below) by (ii) [*]. The "Target Schedule
               Change Calls" shall mean the number equal to [*] multiplied by
               the number of Calls.

[*] The redacted portion, indicated by this symbol, is the subject of a
confidential treatment request and has been filed separately with the Securities
and Exchange Commission.

<PAGE>

          (4) Front Office and Mid/Back Office services shall encompass all
     Services that TRX has historically provided to Expedia.

          (5) The parties will actively work together to analyze the cause of
     Calls, inbound emails, and CRDs (what problems or issues motivate customers
     to Call, email, or CRD TRX), and improve these ratios (determine and
     implement a strategy/process design to prevent or reduce the number of
     Calls, inbound emails and CRDs.)

2.   Costs

     (a)  Expedia shall bear the costs for the following items in connection
with the Services ("Expedia Costs"):

          [*]

     (b)  TRX shall bear all traditional costs associated with providing the
Services ("TRX Costs"). Traditional costs are all costs that have been borne by
TRX and Expedia as of the Execution Date of the AMENDMENT NUMBER 1, except for
the Expedia Costs defined above and as may otherwise be set forth in the
Agreement.

     (c)  Expedia may request reasonable changes in the scope or manner of
performance of the Services being performed by TRX hereunder. Upon receipt of
each such request from Expedia (a "Change Request"), TRX will evaluate the
impact that the Change Request will have on the resources required by TRX to
perform the Services and the amounts then payable to TRX hereunder. TRX will
give an initial response to such requests to Expedia as to the results of such
evaluation (a "Change Proposal") within five (5) business days following receipt
of that Change Request, unless otherwise agreed to by Expedia. If Expedia does
not receive a written response to the Change Request within five (5) business
days, the Change Request is deemed accepted. In the event that, upon the request
of Expedia, TRX performs Services not included under this Agreement, Expedia
shall bear any and all costs of such Services, including, but not limited to,
technology development costs, as mutually agreed upon by the parties.
Notwithstanding the provisions of Section 3 of the Agreement, in the event TRX
provides technology development to Expedia as a Service not included under this
Agreement, (i) if TRX charges Expedia below the then current market rate for
such Service, TRX shall own any and all intellectual property rights for such
developed technology; and (ii) if TRX charges Expedia at or above the current
market rate for such Service, Expedia shall own any and all intellectual
property rights for such developed technology.

     (d)  Notwithstanding the requirements of Section 1(j) of the Agreement,
TRX agrees, at no charge, to annually provide to and ensure that, all its
employees and Expedia-permitted contractors and subcontractors performing any
Services hereunder, agree to

[*] The redacted portion, indicated by this symbol, is the subject of a
confidential treatment request and has been filed separately with the Securities
and Exchange Commission.

<PAGE>

undertake and successfully complete a minimum of [*] hours of training to
prepare TRX to provide the Services outlined in this Agreement (the "Minimum
Annual Training"). [*] hours per quarter of the aforementioned [*] annual hours
of training shall, if needed, be specifically related to enhancements to
Expedia's products and services which materially change the services provided by
TRX. In the event that TRX determines that additional training is needed, due to
Expedia enhancements which materially change the services provided by TRX, TRX
shall provide to Expedia, for review and approval, a proposed training plan,
including a detailed description of the content of such training and the time
required to conclude such training ("TRX Training Request"). Expedia may request
that TRX provide specific training in addition to the Minimum Annual Training
("Expedia Training Request"). Upon receipt of an Expedia Training Request, TRX
will evaluate the Expedia Training Request and provide a written proposal to
Expedia as to the scope of the training, training schedule, and hours required
to provide such training. Expedia agrees to provide the necessary training
materials, for limited duplication, upon request by TRX and following Expedia
approval, to be used by TRX to provide training. Expedia agrees to pay TRX [*]
per hour for any training provided by TRX under a TRX Training Request approved
and accepted by Expedia, or an Expedia Training Request approved and accepted by
TRX.

     (e)  Expedia shall bear all costs of and relating to and any and all
American Express charges incurred in connection with the Services and shall pay
all such costs directly to American Express. TRX agrees to provide to Expedia
the applicable American Express bills and such other documentation reasonably
requested by Expedia, which are in TRX's possession.
