                    dated as of January 10, 2001 (as amended from time to time,
                    the "Credit Agreement") among Trans World Airlines, Inc., as
                    borrower, certain of its subsidiaries, as guarantors, the
                    Lenders from time to time party thereto and AMR Finance,

Dear Bill:

                  This letter is to evidence our agreement as to the following:

                  1. The last sentence of Section 2.2(a) of the Credit Agreement
is hereby deleted in its entirety and the following inserted in lieu thereof:

                  "The Borrower may not request more than one Borrowing per
Business Day."

                  2. The Borrower transferred and sold Receivables to
Constellation on January 10, 11, 12, 15 and 16, 2001, and in exchange therefore,
received cash in an amount equal to approximately $30,000,000 (the
"Transaction"). The Lenders hereby waive any Default or Event of Default arising
solely from the consummation of the Transaction; provided, however, such
transferred Receivables shall not be included as "Receivables" or "Eligible
Receivables" for purposes of calculating the Borrowing Base.

                  3. The following sentence is hereby added as the last sentence
to Section 6.1(a) of the Credit Agreement:

                  "Notwithstanding the foregoing and with respect to the monthly
financial information of the Borrower and it Subsidiaries for the fiscal month
ended December 31, 2000 only, the Borrower shall be permitted to deliver such
information to the Administrative Agent no later than February 15, 2001."

Dear Kate:

         This letter is to evidence our agreement that the phrase "thirty (30)
days" set forth in Section 7.11(b) of the Credit Agreement is hereby deleted and
replaced with the phrase "sixty (60) days".

         As a material inducement to the Lenders to execute this letter,
Borrower hereby represents and warrants to the Lenders that, after giving effect
to this letter and the waiver contained herein: (a) all of the representations
and warranties contained in the Credit Agreement and the other Loan Documents
are true and correct as of the date hereof as though made as of such date
(unless they speak to a specific date or are based upon facts which have changed
by transactions expressly contemplated or permitted by the Credit Agreement);
and (b) no Default or Event of Default exists.

         By execution of this letter in the space provided below, Borrower
consents to the foregoing and ratifies and confirms that the Credit Agreement
and all other Loan Documents, and all renewals, extensions, and restatements of,
and amendments and supplements to, any of the foregoing, are and remain in full
force and effect in accordance with their respective terms.

         The waiver hereby granted by the Lenders does not (a) constitute a
waiver or modification of any other terms or provisions set forth in the Credit
Agreement or any other Loan Document and shall not impair any right that any
Lender may now or hereafter have under or in connection with the Credit
Agreement or any other Loan Document, and (b) impair any

respective successors and permitted assigns.

                  This letter, when countersigned by the Required Lenders, shall
be a "Loan Document" as defined and referred to in the Credit Agreement and the
other Loan Documents, and may be signed in any number of counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument. THIS LETTER SHALL BE GOVERNED BY AND CONSTRUED IN

the final, entire agreement among the parties hereto and supersede any and all
