REPLY OF CONCESIONARIA VUELA COMPAÑÍA DE AVI ACIÓN, S.A.P.I. DE C.V. d/b/a VOLARIS AND REQUEST FOR IMMEDIATE ACTION Concesionaria Vuela Compañía de Avi ación, S.A.P.I. de C.V. d/b/a Volaris (“Volaris”) submits this reply to the answer of American Airlines, Inc. (“American”) filed in the captioned docket, and respectfully requests immediate action on its application to serve Monterrey-Chicago, Mexico City-Las Vegas and Mexico City-Los Angeles.

American states in its answer that it does not oppose approval of Volaris’ application provided its application for extrabilateral authority to institute additional U.S. carrier service in the New York-Mexico City market is approved. 1 While American attempts to equate its application with Volaris’, the relief sought by American is substantially different—and greater—than th at sought by Volaris, which is narrowly tailored to address a specific competitive imbalance currently affecting Mexican carriers.

1 Application of American Airlines, Inc., for an Exemption, Docket DOT-OST-2011-___, July 5, 2011Reply of Concesionaria Vuela Compañía de Aviación, S.A.P.I. de C.V. d/b/a Volaris Docket DOT-OST-2011-0117 July 6, 2011

- 2 - Volaris requests authority only to repl ace service in three U.S.-Mexico markets that was discontinued by another Mexican ca rrier nearly one year ago. Approval of Volaris’ application will therefore not resu lt in more than the bilaterally-authorized number of carriers operating in any U.S.-Mexico market. American’s request is not comparable to Volaris’ application and should not be treated as such. American requests approval to operate as an additional U.S. carrier in a double designation market that is served currently by two U.S. carriers—Delta and Continental. If its application were approved, American would become the third operating U.S. carrier in the New York-Mexico market in competition with a single Mexican carrier, exacerbating the competitive im balance that now exists as a result of Mexicana’s service suspension. In contrast , approval of Volaris’ application would simply restore in three U.S.-Mexico markets the level of Mexican carrier competition that existed prior to August 2010, and that was ag reed to by the United States and Mexico

under the bilateral. Moreover, Volaris stated specifically in its application that it would terminate

service in the affected U.S.-Mexico market if and when Mexicana resumes operations, thus ensuring that no more than two carriers of either side will operate in a double designation market at any time, as the bilateral requires. In asserting that the “sameReply of Concesionaria Vuela Compañía de Aviación, S.A.P.I. de C.V. d/b/a Volaris Docket DOT-OST-2011-0117 July 6, 2011

- 3 - considerations” apply to its application as Volaris’, American ignores this important condition as well as the bilateral provisions on which it is based. 2 Approval of Volaris’ application shoul d not be delayed while the Department considers American’s request. The three ma rkets for which Volaris requests authority

have been without a second Mexican carrier since August 2010. The peak summer travel season has begun and Volaris must begin sales immediately if these services are to be inaugurated successfully. Consumers have b een denied the benefits of a choice in Mexican carriers for long enough; nothing in Amer ican’s reply or answer disputes this

fact or that additional Mexican carrier co mpetition would benefit consumers. Volaris respectfully requests that the Department immediately approve its application so that it can begin marketing and sale of its Mont errey-Chicago, Mexico City-Las Vegas and Mexico City-Los Angeles services. Respectfully submitted, /s/ Alfonso Ascencio Triujeque
