   Air Services Agreement, dated as of June 11, 2001 by and between Chautauqua
            Airlines, Inc. ("Chautauqua") and AMR Corporation ("AMR")


Dear Mr. Bedford:

                  We refer to the agreement described above (the "Air Services
Agreement"). (Unless otherwise defined in this letter, capitalized terms that we
use below have the meaning set forth in the Air Services Agreement.)

Chautauqua has informed AMR that Chautauqua wishes to take delivery of three
Firm Approved Aircraft under a financing arrangement that is not a Lease
meeting the requirements of Section 7.03(c) of the Air Services Agreement
(such financing arrangement, and any refinancing of such arrangement that is
also not a Lease meeting the requirements of such Section 7.03(c), an
"Alternative Financing"). The three Firm Approved Aircraft referred to above
have serial numbers 145538, 145543 and 145544, respectively (each, a
"Specified Aircraft"). AMR consents, on the following terms, to such
deliveries under such Alternative Financing arrangements.

1)   Until such time as Chautauqua is able to close an Alternative Financing
     arrangement with Banco Nacional de Desenvolvimento Economico e Social or
     its affiliate Agencia Especial de Financimento Industrial - FINAME
     (either being referred to hereafter as "BNDES"), Chautauqua will only
     enter into an Alternative Financing with Embraer (or an affiliate
     thereof) (an "Embraer Alternative Financing"), and thereafter, Chautauqua
     will only enter into an Alternative Financing (including, without
     limitation, a refinancing of an Embraer Alternative Financing other than
     pursuant to a Lease meeting the requirements of Section 7.03(c) of the Air
     Services Agreement) with BNDES.

2)   Chautauqua acknowledges that AMR and AA intend to negotiate with BNDES
     forms of leveraged lease documentation (the "AA/BNDES Form Lease") based on
     existing

Commission.

     aircraft loans by BNDES to AMR affiliates and acceptable to AMR for
     submission to lessors (which may include Solitair Corp., an affiliate of
     Chautauqua; Chautauqua or a subsidiary of Chautauqua (each a "CAI
     Affiliate") as the equity participant) with respect to any Firm Approved
     Aircraft financed by BNDES that are subsequently leased to AA or an AMR
     affiliate (a "Permitted Assignee") pursuant to either the "put" or "call"
     provisions of the Air Services Agreement. Any AA/BNDES Form Lease shall be
     subject to the approval of the lessor under such leveraged lease.
     Chautauqua and AMR intend to negotiate leveraged lease documentation based
     on the AA/BNDES Form Lease and acceptable to AMR for lease to an AMR
     affiliate with a CAI Affiliate as equity participant acting through a trust
     or similar entity (such lease, a "Chautauqua Leasing Arrangement"). AMR and
     Chautauqua and their respective affiliates shall not have any liability
     under this letter for any failure to reach agreement as to an AA/BNDES Form
     Lease, as to a Chautauqua Leasing Arrangement, or as to any Alternative
     Financing or other arrangement.

3)   Until the date that (i) AMR and BNDES agree to the terms of an AA/BNDES
     Form Lease, (ii) AMR and Chautauqua agree on the terms of a Chautauqua
     Leasing Arrangement and, (iii) financing for a Specified Aircraft has
     been put in place with BNDES that permits such Specified Aircraft to be
     leased to a Permitted Assignee pursuant to an AA/BNDES Form Lease (and,
     if applicable, under a Chautauqua Leasing Arrangement) upon exercise of
     any put or call option referred to below, Chautauqua will not enter into
     any Alternative Financing for any Specified Aircraft other than the
     Embraer Alternative Financing. If the conditions of the preceding
     sentence are satisfied, Chautauqua may enter into an Alternative
     Financing of a Specified Aircraft on such agreed terms without further
     approval by AMR of such financing (a "Definitive Alternative
     Arrangement") for purposes of the Air Services Agreement.

4)   At the time of (a) a transfer to AMR or an affiliate of a leasehold
     interest in a Specified Aircraft or (b) a lease to an AMR affiliate
     under a Chautauqua Leasing Arrangement, in either case pursuant to a
     One-Time Put Option, a Call Option or a One-Time Call Option, the
     Specified Aircraft shall be subject only to the lien of the Alternative
     Financing (but otherwise free and clear of all liens, including liens
     permitted by the Alternative Financing).

5)   At such time as Chautauqua enters into an [*], provided that (a) the
     "Lender's Debt Rate" shall be the interest rate charged by [*], and (b)
     the illustrative Average Monthly Accounting Rent shall be [*] rather
     than the figure set forth on such [*] in each case subject to further
     adjustment as provided in [*]. In the event Chautauqua subsequently
     enters into a Definitive Alternative Financing with BNDES, Chautauqua's
     reimbursable aircraft

     ownership costs with respect to the respective Specified Aircraft shall
     be recalculated pursuant to [*], as if such aircraft was leased by
     Chautauqua, provided that the illustrative Average Monthly Accounting
     Rent shall be [*] rather than the figure set forth on such Exhibit P
     subject to further adjustment as provided in Exhibit P. The foregoing is
     not intended to amend or modify Schedule E-3, Section 1. J of the Air
     Services Agreement or Schedule E-3, Section 1. K of the current proposed
     draft of the Amended and Restated Air Services Agreement.

6)   AMR agrees that it may not exercise either of its One-Time Call Option
     or its Call Option under 7.03 of the Air Services Agreement and
     Chautauqua agrees that it may not exercise its One-Time Put Option under
     Section 7.03 of the Air Services Agreement with respect to any Specified
     Aircraft that is subject to an Alternative Financing until such time, if
     any, that a Definitive Alternative Financing or a Lease is entered into
     with respect to such aircraft.

7)   Except as otherwise expressly provided herein, this letter does not limit
     (a) any of AMR's One-Time Call Option or AMR's Call Option or
     Chautauqua's One-Time Put Option pursuant to Section 7.03 of the Air
     Services Agreement, which options will remain in effect with respect to
     each Specified Aircraft, or (b) any of the other rights or obligations
     of Chautauqua or AMR under the Air Services Agreement.

8)   This letter agreement does not apply to any Firm Approved Aircraft other
     than the Specified Aircraft.

9)   AMR agrees that each Specified Aircraft shall be placed into service under
     the Air Services Agreement and waives any claim for any delay in placing
     such Aircraft into service, including any claim for liquidated damages
     under Section 1.02(a) of the Air Services Agreement. AMR further
     acknowledges and agrees that Chautauqua has the right under certain
     circumstances to return the Specified Aircraft to Embraer and agrees that
     in the event Chautauqua exercises such right, (a) such Aircraft shall
     be removed from service under the Air Services Agreement, (b) such
     Aircraft shall no longer be subject to the terms and conditions of the
     Air Services Agreement, (c) the Air Services Agreement shall be amended
     mutatis mutandi to reflect the removal from service of such Aircraft,
     and (d) AMR consents to the removal from service of such Aircraft.

         Except as modified hereby, the Air Services Agreement remains in
effect. This letter agreement shall be governed by the internal laws of Texas
without reference to conflict of laws rules.

         This letter agreement may be executed in separate counterparts, each of
which when so executed and delivered shall be an original, but all such
counterparts shall together constitute but one and the same instrument.
Execution may be effected by delivery of facsimiles of signature pages (and the
parties shall follow such delivery by prompt delivery of originals of such
pages). This letter agreement may be executed in any
