Ladies and Gentlemen:

            1. Reference is made to the Underwriting Agreement between us dated
September 6, 2001 (the "Original Agreement"; capitalized terms used herein,
unless defined herein, are being used herein as defined therein). Delta Air
Lines, Inc. hereby proposes to amend the Original Agreement by substituting for
Schedule A thereto the Revised Schedule A attached to this Amendment.

            2. In all respects not inconsistent with the terms and provisions of
this Amendment, the Original Agreement shall continue to be in full force and
effect in accordance with the terms and conditions thereof. From and after the
date hereof, each reference to the Original Agreement in any other instrument or
document shall be deemed a reference to the Original Agreement as amended
hereby, unless the context otherwise requires.

            If the foregoing is in accordance with your understanding, please
sign and return a counterpart hereof to the Company, plus a counterpart hereof
for the Company's counsel, whereupon this letter shall constitute a binding
agreement between each of the Underwriters and the Company. It is understood
that your acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among Underwriters,
the form of which shall be submitted to the Company for examination upon
request, but without warranty on your part as to the authority of the signers
thereof.

                                    Very truly yours,

                                    DELTA AIR LINES, INC.
