Grupo Aeroportuario del Pacifico Update

Grupo Aeroportuario del Pacífico, S.A.B. de C.V., (NYSE: PAC; BMV: GAP) ("the Company” or "GAP”) announced that at the Company’s Board of Directors’ Meeting held on August 26, 2011, and in accordance with Mexico’s Securities Market Law and the Company’s by-laws, the Board appointed as Directors by co-optation the following individuals: Jaime Cortés Rocha, Francisco Glennie y Graue, José Alejandro Casas Gonzalez, Carlos Bravo and Leon Falic. These appointments will serve as Directors until they are ratified or substituted at the next Shareholders’ Meeting of the Company. If ratified, their independence will also be certified.

In addition, the Board of Directors appointed Eduardo Gallástegui Armella as a Director by co-optation. Mr. Gallástegui has served as a Director of the Company after being designated by Grupo México S.A.B. and one of its subsidiaries, as shareholders of the Company in accordance with Article 50 of Mexico’s Securities Market Law and Article 15 of the Company’s by-laws, during the Shareholders’ Meeting of the Company held July 22 to 25, 2010. His independence will also be certified at the Shareholders’ Meeting of the Company.

These appointments by co-optation were made as a result of the resignation of two independent Directors of the Company and as a consequence of the fact that as a result of the suspension issued by a judge of Resolutions VII and VIII of the Company’s Shareholders’ Meeting held April 27, 2011, the majority of the Directors would have ceased their duties due to the conclusion of their legally and statutorily mandated terms. Moving forward, if the suspension by the judge is lifted prior to the next Shareholders’ Meeting and the nominations from the Shareholders’ Meeting held April 27, 2011 take full effect, the appointments by co-optation made on August 26, 2011 will no longer be effective with respect to those Directors that have not resigned.

Furthermore, the Board of Directors has determined that the Audit Committee of the Company will be comprised of Mssrs. José Alejandro Casas González, Carlos Bravo and Jaime Cortés Rocha.
