GRUPO AEROPORTUARIO DEL PACIFICO, S.A.B. DE C.V. ANNOUNCEMENT REGARDING SWINE FLU VIRUS

Guadalajara, Jalisco, Mexico, April 27, 2009 - Grupo Aeroportuario del Pacífico, S.A.B. de C.V. (NYSE:PAC; BMV:GAP) (“the Company” or “GAP”) today announced the following:

On Sunday, April 26, 2009, the Mexican National Health Department confirmed the existence of Type A and B viruses in humans as well as the circulation of another strain of the virus, called Swine Influenza (Swine Flu Virus).

As a result of the alerts, the Health Departments in most of the Mexican states in which GAP’s airports operate set up epidemiology surveillance posts to be on the lookout for any persons affected by the symptoms, in order to maintain control over this outbreak and grant timely attention and follow up with those persons showing any signs of the virus. These symptoms are:

We are offering the health authorities all of the support required for any activity they consider necessary at each of our airports.

With the support of the airlines and the authorities at each of the terminal areas, we expect to successfully detect any passenger showing any of these signs. These passengers must be channeled via the control posts so that the Health Department can review the situation and, if necessary, take samples to rule out if the passenger is a carrier of the swine influenza virus.

Today, operations at the airports that GAP operates remained normal, that is, there were no cancelations of national or international flights.

The Company, together with the airport authorities and the airlines, will be in constant communication in order to update the market on instructions from the Health Department.

It is important to mention that at this moment we do not know the full impact that this situation will have on passenger traffic; this will depend on the amount of time that the risk prevails.
