**ANSWER OF AMERICAN AIRLINES, INC.**

American Airlines, Inc. hereby answers the application submitted by Delta Air Lines, Inc. on April 8, 2010

seeking a frequency allocation to serve between Detroit and

Sao Paulo. Delta’s application is outside the scope of the

U.S.-Brazil Memorandum of Understanding of June 26, 2008

(Attachment B, Annex 1, Section II (2), p. 4 n. 5), and nonresponsive to the Department’s notice of March 23, 2010

inviting applications. Sao Paulo is not an eligible destination for the new frequencies that take effect on October 1,

2010.

For all the reasons set forth in our motion to

dismiss of April 12, 2010 (DOT-OST-2010-0090) and reply of

April 23, 2010 (DOT-OST-2010-0088 and DOT-OST-2010-0090),

which we incorporate herein by reference, Delta’s Sao Paulo

application should be dismissed.- 2 –

Respectfully submitted,
