GRUPO AEROPORTUARIO DEL PACÍFICO INFORMS REGARDING THE

 INDEFINITE SUSPENSION OF OPERATIONS OF GRUPO MEXICANA DE

AVIACIÓN

Guadalajara, Jalisco, Mexico, August 30, 2010 - Grupo Aeroportuario del Pacífico, S.A.B. de C.V., (NYSE: PAC; BMV: GAP) (“the Company” or “GAP”) announces that as of 12:00 noon on Saturday, August 28, 2010, Grupo Mexicana de Aviación, or “GMA”, which operates through its three subsidiaries, Compañía Mexicana de Aviación (Mexicana), Aerovías Caribe, S.A. de C.V. (Mexicana Click), and Mexicana Inter, S.A. de C.V. (Mexicana Link), has suspended operations indefinitely.

On the date of suspension of its operations, GMA was present at 10 of GAP’s 12 airports (Guanajuato, Guadalajara, La Paz, Los Mochis, Morelia, Mexicali, Puerto Vallarta, Los Cabos, Tijuana and Manzanillo); Furthermore, during 2009, GMA represented 12.63% of GAP’s total revenues.

During the first half of 2010, GMA transported 1,869,636 total passengers in GAP’s network representing 18.26%, making it the third-largest airline in terms of the number of passengers transported within GAP’s airports (the first being Grupo Aeromexico and the second being Volaris).

During the first half 2010, GMA operated a total of 13 exclusive routes (the sole operator), in which 403,384 passengers were transported and 14 dominated routes (routes in which GMA’s market share was greater than 50%), in which 344,680 passengers were transported.  The remaining passengers were transported on a total of 30 competitive routes (routes in which GMA’s market share was less than 50%), which transported a total of 1,121,572 passengers.

GAP estimates that the highest-density and highest-occupancy routes operated by GMA to date will be gradually substituted by other airlines via the opening of new routes or increased frequencies, or in some cases, the absorption of passengers by existing or available seats on the routes mentioned above.  It is worth noting that the reaction time of domestic airlines to cover routes to the United States will be constrained in the short term by the FAA’s safety rating downgrade of the Mexican Aeronautical Authority, which restricts the opening of new routes to the United States.

It is also worth noting that during 2009 and the first half 2010, aeronautical revenues from GMA represented 16.23% and 17.03% of GAP’s total aeronautical revenues, respectively. As of August 27, 2010, GAP recognizes a pending balance from GMA of Ps. 49.9 million.  Of this amount, Ps. 41.2 million correspond to Airport Usage Fees, which GMA collected on behalf of GAP’s airports from passengers on Mexicana, Click or Link as of August 27, 2010.  This amount has yet to be received by GAP, but in the case of GMA’s insolvency proceeding or bankruptcy, this amount should not be considered as part of GMA’s liabilities subject to its creditors as it is GAP’s exclusive property. GAP will initiate the necessary legal proceedings so that the judges and legal authorities overseeing the insolvency petition pr ioritize GAP’s claim for its Airport Usage Fees.

Updated Guidance

Due to the expected short-term impact of GMA’s suspension of operations, GAP has adjusted its 2010 estimates as follows:

·   Total passenger traffic will increase between 2.5% and 4%;

·   Aeronautical revenue will increase between 13% and 16%;

·   Commercial revenue will grow between 3.5% and 5%;

·   Total revenues will increase between 11% and 13.5%;

·   Cost of services will increase from 13% to 15%;

·   EBITDA margin will be between 64% and 65%, with an increase between 9% and 11% in absolute terms.

·   Effective tax rate will be 35%.
