GUADALAJARA, Mexico, June 4 /PRNewswire-FirstCall/ -- Grupo Aeroportuario del Pacifico, S.A.B. de C.V. (NYSE: PAC; BMV: GAP) ('the Company' or 'GAP') announced today preliminary terminal passenger traffic figures for the month of May 2009 compared to traffic figures for May 2008.

During May 2009, total terminal passengers decreased 36.6% compared to the previous year; international passenger traffic decreased 43.7% and domestic passenger traffic decreased 33.3% compared to May 2008.

Regarding material events for the month, during the last week of May, the epidemiological alert for the AH1N1 flu virus epidemic was raised, which resulted in the cancellation of flights from Canada, the U.S. and some domestic flights due to low load levels. This resulted in the decline of international and domestic passenger traffic. The decrease in traffic at the Aguascalientes airport, however, was due to the cancellation of the San Marcos Festival, which attracts thousands of tourists to this city each year.

Additionally, the Mexican Federal Aviation Authority suspended Aviacsa's operations due to irregularities in aircraft safety. Aviacsa operates at the airports of Guadalajara, Hermosillo, Puerto Vallarta and Tijuana. As of May 2009, Aviacsa transported 298,011 passengers for the year, 5.9% of domestic passengers and 3.6% of GAP's total passengers.
