                  AMENDMENT 7 AIRFRAME PRICE REVISION FORMULA

      l.    BASE PRICE

            The Base Price of the A320 Airframe for the Amendment 7 A320
            Aircraft, the Base Price of the A319 Airframe for the Amendment 7
            A319 Aircraft and the Base Price of the A321 Airframe for the
            Amendment 7 A321 Aircraft are as set forth in the Amendment in
            January 2003 delivery conditions and will be escalated to the date
            of Aircraft (excluding A318 Aircraft) delivery as set forth in this
            Exhibit D-2.

      2.    BASE PERIOD

            The above Base Price has been established in accordance with the
            averaged economic conditions prevailing in December 2001, January
            2002, February 2002 and corresponding to theoretical delivery
            conditions prevailing in January 2003 as defined by [*] index values
            indicated in Paragraph 4 of this Exhibit D-2.

            The Base Price is subject to adjustment for changes in economic
            conditions as measured by data obtained from the US Department of
            Labor, Bureau of Labor Statistics, and in accordance with the
            provisions of Paragraphs 4 and 5 of this Exhibit D-2.

            [*] index values indicated in Paragraph 4 of this Exhibit D-2 will
            not be subject to any revision of these indexes.

      [*]

      In determining the Revised Base Price at delivery of the Amendment 7
      Aircraft (excluding A318 Aircraft), each quotient will be calculated to
      the nearest ten thousandth (4 decimals). If the next succeeding place is
      five (5) or more, the preceding decimal place will be raised to the next
      higher figure. The final factor will be rounded to the nearest ten
      thousandth (4 decimals). After final computation, Pn will be rounded to
      the next whole number (0.5 or more rounded to l).

5.    GENERAL PROVISIONS

5.1   Substitution of Indexes

      In the event that:

      (i)   the U.S. Department of Labor substantially revises the methodology
            of calculation of any of the indexes referred to hereabove, or

      (ii)  the U.S. Department of Labor discontinues, either temporarily or
            permanently, any of the indexes referred to hereabove, or

      (iii) the data samples used to calculate any of the indexes referred to
            hereabove are substantially changed,

      the Seller will select a substitute index.

      Such substitute index will reflect as closely as possible the actual

            In determining the Revised Reference Price [*] shall be calculated
            to the nearest tenth (1 decimal). Each quotient [*] shall be
            calculated to the nearest ten-thousandth (4 decimals). If the next
            succeeding place is five (5) or more the preceding decimal place
            shall be raised to the next higher figure.

            After final computation Pn shall be rounded to the nearest whole
            number (0.5 rounds to 1).

5           GENERAL PROVISIONS

5.1         The revised Reference Price at the date of Aircraft Delivery shall
            be the final price and shall not be subject to any further
            adjustments in the indexes.

5.2         If no final index values are available for any of the applicable
            month, the then published preliminary figures shall be the basis on
            which the Revised Reference Price shall be computed.

5.3         If the US Department of Labor substantially revises the methodology
            of calculation or discontinues any of the indexes referred to in
            this Attachment I to Exhibit 2, the Seller shall reflect the
            substitute for the revised or discontinued index selected by
            INTERNATIONAL AERO ENGINES, such substitute index to lead in
            application to the same adjustment result, insofar as possible, as
            would have been achieved by continuing the use of the original index
            as it may have fluctuated had it not been revised or discontinued.

            Appropriate revision of the formula shall be made to accomplish this
            result.

5.4         Should the above escalation provisions become null and void by
            action of the US Government, the price shall be adjusted due to
            increases in the costs of labor and material which have occurred
            from the period represented by the applicable Reference Price
            Indexes to the Fifth (5th), Sixth (6th) and Seventh (7th) months
            averaged prior to the scheduled delivery of the applicable Aircraft.

5.5         The Revised Reference Price at delivery of the Aircraft in no event
            will be less than the Reference Price defined in Paragraph 4.2.A.3.3
            to Amendment 7 to the Agreement for the V2524-A5, in Paragraph
            5.2.A.3.3 to Amendment 7 to the Agreement for the V2527-A5, and in
            Paragraph 6.2.A.3.3 to Amendment 7 to the Agreement for the
            V2533-A5, as applicable.

                                 LICENSE FOR USE
                  OF THE PERFORMANCE ENGINEERING PROGRAMS (PEP)

1.       GRANT

         The Seller grants to the Buyer the right to use the Performance
         Engineering Programs (PEP) in machine-readable form on a single
         computer network during the term of this license agreement (the
         "License Agreement").

         Use of the PEP in readable form shall be limited to one (1) copy.
         However, the Buyer may make duplicate copies, provided that they are
         either contained in the same network as the original copy, or produced
         for checkpoint and restart purposes or made with the consent of the
         Seller for a specific need.

2.       MERGING

         The PEP may be used and adapted in machine-readable form for the
         purpose of merging it into other program material of the Buyer, but, on
         termination of this License Agreement, the Buyer shall remove the PEP
         from the other program material with which it has been merged.

         The Buyer agrees to reproduce the copyright and other notices as they
         appear on or within the original media on any copies that the Buyer
         makes of the PEP.

3.       PERSONAL LICENSE

         The above described license is personal to the Buyer and its computer
         service contractors, nontransferable and nonexclusive.

4.       INSTALLATION

         It is the Buyer's responsibility to install the PEP and to perform any
         mergings and checks. The Seller shall, however, assist the Buyer's
         operations engineers in the initial phase following the delivery of the
         PEP until such personnel reach the familiarization level required to
         make inputs and correlate outputs.

5.       PROPRIETARY RIGHTS AND NONDISCLOSURE

5.1      The PEP and the copyright and other proprietary rights of whatever
         nature in the PEP are and shall remain with the Seller. The PEP and its
         contents are designated as confidential.

5.2      The Buyer undertakes not to disclose the PEP, parts thereof or its
         contents to any third party except the Buyer's computer service
         provider, without the prior written consent of the Seller. Insofar as
         it is necessary to disclose aspects of the PEP to employees, such
         disclosure is permitted only for the purpose for which the PEP is
         supplied and only to the employee who needs to know the same.

6.       CONDITIONS OF USE

6.1      The Seller does not warrant that the PEP shall contain no errors.
         However, should the PEP be found to contain any error at delivery of
         the PEP, the Buyer shall notify the Seller promptly thereof and the
         Seller shall take all proper steps to correct the same at its own
         expense.

6.2      The Buyer shall ensure that the PEP is correctly used in appropriate
         machines as indicated in the Performance Programs Manual (PPM) and that
         staff are properly trained to use the same, to trace and correct
         running faults, to restart and recover after fault and to operate
         suitable checks for accuracy of input and output.

6.3      It is understood that the PPM is the user's guide of the PEP and that
         the Buyer shall undertake to use the PEP in accordance with the PPM.

6.4      The PEP is supplied under the express condition that the Seller shall
         have no liability in contract or in tort arising from or in connection
         with the Buyer's use of or inability to use the PEP.

7.       DURATION

         Subject to the Buyer's compliance with the terms of this License
         Agreement, the rights under this License Agreement shall be granted to
         the Buyer for as long as the Buyer operates an Aircraft to which the
         PEP refers.

Re:      FLEXIBILITY

Dear Ladies and Gentlemen:

         In connection with the execution of Amendment No. 7 (the "Amendment")
to the Airbus A319/A320 Purchase Agreement dated as of September 12, 1997, (the
"Agreement") between AVSA S.A.R.L., (the "Seller") and AMERICA WEST AIRLINES,
INC., (the "Buyer"), the Buyer and the Seller have agreed to amend Letter
Agreement No. 2 to Amendment No. 3 to the Agreement, as amended by Amendments 4,
5 and 6, with this Letter Agreement No. 2 to the Amendment (the "Letter
Agreement") to the Amendment. For the purposes of this Letter Agreement only,
the term Aircraft as defined under the Agreement will be deemed to include
Amendment No. 7 Aircraft only. Capitalized terms used herein and not otherwise
defined in this Letter Agreement will have the meanings assigned thereto in the
Agreement or the Amendment. The terms "herein," "hereof" and "hereunder" and
words of similar import refer to this Letter Agreement.

         Both parties agree that this Letter Agreement will constitute an
integral, nonseverable part of the Amendment, except that if the Agreement or
the Amendment and this Letter Agreement have specific provisions that are
inconsistent, the specific provisions contained in this Letter Agreement will
govern.

  1.     Cancellation of Unexercised Option Aircraft and Purchase Right Aircraft

         The remaining [*] unexercised Option Aircraft provided in Paragraph 2
         of Letter Agreement No. 2 to Amendment No. 3 to the Agreement, as
         amended, and the twenty-five (25) Purchase Right Aircraft provided in
         Paragraph 3 of Letter Agreement No. 2 to Amendment No. 3 to the
         Agreement, as amended, are hereby cancelled and neither party has any
         remaining rights or obligations with respect thereto. Paragraph 2 of
         Letter

AWE - A318/A320 - LA2-AM7                LA2 - 1

<PAGE>

         Agreement No. 2 to Amendment No. 3, as amended shall have no further
         force and effect with respect to any unexercised Option Aircraft.
         Paragraph 3 of Letter Agreement No. 2 to Amendment No. 3, as amended,
         is cancelled and shall have no further force and effect.

2.       New Purchase Right Aircraft

2.1      The Seller hereby grants to Buyer the right to purchase up to fourteen
         (14) New Purchase Right Aircraft, which the Buyer will have the right
         to purchase as either an A319, A320 and/or A321 Aircraft for delivery
         dates in [*]

2.2      The New Purchase Right Aircraft will remain without reserved delivery
         quarters by the Seller [*] until the Buyer requests a delivery date by
         written notice to the Seller, such notice also specifying the type of
         New Purchase Right Aircraft the Buyer is considering to firmly
         purchase. The Seller will then provide in writing within [*], subject
         to its industrial and commercial constraints at the time, a delivery
         month and year, which will remain subject to prior sale and other
         disposition until written confirmation of acceptance from the Buyer and
         concurrent payment of a Purchase Right Aircraft Predelivery Payment as
         set out in [*] of Letter Agreement No. 4 to the Amendment (upon which
         the New Purchase Right Aircraft will be an Amendment 7 Aircraft under
         the Agreement).

2.3      In connection with the unexercised Option Aircraft cancelled pursuant
         to Paragraph 1, above, the Seller acknowledges to have already received
         as of date hereof, from the Buyer Option Fees in the amount of US $[*]
         and the Seller and the Buyer agree that such Option Fees will be
         credited to the Buyer in increments of [*] against the New Purchase
         Right Aircraft Predelivery Payment to be paid by the Buyer to the
         Seller upon the exercise of each of the New Purchase Right Aircraft (as
         described in [*] of Letter Agreement No. 4 of the Amendment).

2.4      Purchase Incentives for New Purchase Right Aircraft are set forth in
         Letter Agreement No. 3 to the Amendment.

3.       A318 Aircraft Conversion and Cancellation Rights

         At the Buyer's request, the Seller grants the Buyer the right to
         convert up to fifteen (15) A318 Aircraft to either an Amendment 7 A319
         Aircraft, Amendment 7 A320 Aircraft and/or Amendment 7 A321 Aircraft
         (the "Converted A318 Aircraft") or alternately to cancel the A318
         Aircraft. The Buyer may exercise such conversion and cancellation
         rights as follows:

         (i)      [*]

         (ii)     [*]

         (iii)    [*]

5.       DELIVERY

         Notwithstanding any provisions of the Agreement to the contrary, the
         Seller shall not be obligated to deliver to the Buyer more than a total
         of [*] (including A318 Aircraft, [*], New Purchase Right Aircraft and
         Amendment 7 Aircraft) in any given calendar year. Any provision of the
         Agreement, as amended, or of any other agreement between the parties
         establishing a lower yearly threshold on the Seller's delivery
         obligations shall have no further force or effect.

6.       ASSIGNMENT

         Notwithstanding any other provision of this Letter Agreement or of the
         Agreement, this Letter Agreement and the rights and obligations of the
         Buyer hereunder will not be assigned or transferred in any manner
         without the prior written consent of the Seller, and any attempted
         assignment or transfer in contravention of the provisions of this
         Paragraph 6 will be void and of no force or effect.

America West Airlines, Inc.
Phoenix Sky Harbor International Airport

Phoenix, Arizona 85034
Attention:  Tom Weir, Treasurer

Subject:    Side letter No. 15 to the Amended and Restated V2500 Support
            Contract between America West Airlines, Inc., and IAE International
            Aero Engines AG dated 7 October 1998

Dear Tom:

We refer to the Amended and Restated V2500 Support Contract between America West
Airlines, Inc. ("AWA") and IAE International Aero Engines AG ("IAE") dated 7
October 1998 (said Amended and Restated V2500 Support Contract, being
hereinafter referred to as the "Contract"). Capitalized terms used herein which
are not otherwise defined shall have the same meaning as those given to them in
the Contract.

1.    FINANCIAL SUPPORT

      1.1   Fleet Introductory Assistance Credit

            IAE shall support AWA's firm and binding commitment to purchase from
            AVSA S.A.R.L. ("Airbus") seven (7) new, firmly ordered A319 aircraft
            and ten (10) new, firmly ordered A320 aircraft powered by new
            V2524-A5 and V2527-A5 Propulsion Systems, respectively, to be
            delivered in accordance with the schedule set forth in Exhibit A to
            this Side Letter (the "Firm 2004 Aircraft") pursuant to an Amendment
            to the existing Purchase Agreement by and between Airbus and AWA
            (the "Airbus Purchase Agreement"). To assist AWA with introducing
            the Firm 2004 Aircraft into its fleet, IAE will provide fleet
            introductory assistance credits to AWA of $[*] of the A319 aircraft
            and $[*] of the A320 Aircraft, all in January 2003 U.S. Dollars (the
            "Credits").

<PAGE>

      1.2   Fleet Expansion Commitment

            a.    Airbus has provided AWA with purchase rights for up to fifteen
                  (15) A320 family aircraft. AWA agrees that if they exercise
                  any of these purchase right aircraft, they will be powered by
                  either V2500-A5 or Pratt & Whitney 6000 propulsion systems,
                  whichever may be applicable (with respect to the V2500-A5
                  powered aircraft these shall be referred to as the "2004
                  Purchase Right Aircraft"). To assist AWA with introducing such
                  2004 Purchase Right Aircraft into its fleet, should such
                  aircraft be V2500-A5 powered, IAE will grant to AWA the same
                  credits for such aircraft as set forth in Clause 1.1 above.
                  All Purchase Right Aircraft shall be delivered to AWA [*].

            b.    [*]

            c.    AWA agrees to purchase new spare Engines at the appropriate
                  thrust rating at prices no less favorable to AWA than the Firm
                  2004 Spare Engines (as defined below) with each of the [*] and
                  [*] 2004 Purchase Right Aircraft (the "2004 Purchase Right
                  Spare Engines"). At the request of AWA, IAE will adjust the
                  contractual spare engine coverage requirements for various
                  thrust categories in order to more closely approximate the
                  thrust coverage requirements of AWA's V2500-A5 powered fleet.
                  [*]

      1.3   Credit Escalation

            The credits described in Clauses 1.1 and 1.2 above are subject to
            escalation in accordance with the IAE Escalation Formula set forth
            in Exhibit B-1 to this Side Letter from the base month of [*] to the
            date of delivery to Airbus by IAE of the Propulsion Systems for the
            corresponding Firm 2004 Aircraft or 2004 Purchase Right Aircraft.

      1.4   Spare Engine Purchase

            AWA firmly and irrevocably agrees to purchase two (2) new spare
            V2524-A5 Engines and three (3) new spare V2527-A5 Engines to be
            delivered in accordance with the delivery schedule set forth in
            Exhibit A to this Side Letter (together the "Firm 2004 Spare
            Engines"); provided, however, AWA (a) shall not be required to
