Re: Notice of American Airlines (Chicago-Mexico City) (DOT-OST-2004-16945)_____________________________

Dear Mr. Gretch:

American Airlines, Inc. hereby provides notice that, effective December 16, 2010, or as soon as all necessary authorizations are obtained, it will resume nonstop operations with its own aircraft between Chicago and Mexico City.

American will operate daily nonstop service on a yearround basis using 148-seat B737 aircraft (16C/132Y). Southbound, American will depart Chicago at 0900 and arrive in Mexico City at 1315. Northbound, American will depart Mexico City at 1420 and arrive in Chicago at 1810.

American’s certificate of public convenience and necessity for Route 628 authorizes scheduled foreign air transporttation of persons, property, and mail on several U.S.-Mexico transborder route segments, including Chicago-Mexico City. American started operating ORD-MEX service in the 1940s. On May 16, 2004, American began reciprocal codeshare services with Mexicana between Chicago and Mexico City, as authorized by Notice of Action Taken in this docket dated April 29, 2004. American continued to display the AA* code on Mexicana’s Chicago-Mexico City flights until Mexicana ceased operations on August 11, 2010.

On May 9, 2009, American suspended its own-metal ORD-MEX nonstop flights, but inadvertently did not provide notice to the Department as required by Order 99-6-6, June 4, 1999, p. 9:- 2 –

“Any U.S. carrier wishing to convert its authorized nonstop transborder operations from direct carrier service (designation) to service involving only the display of its code on another Mexican or U.S. carrier’s flights (codeshare-only authorization), or vice versa, must file a notice with the Depart- ment . . . . If no party opposes the request, andsufficient designations or codeshare-only authorizations, as applicable, are available, we will convert the operations as requested.”

By this letter, American provides notice that it will resume own-metal nonstop operations between Chicago and MexicoCity effective December 16, 2010, and requests that the Department convert American’s authorized ORD-MEX operations from codeshare-only to direct carrier service.

We are polling the parties named on the attached service list for non-objections.

Respectfully submitted,

Carl B. Nelson
