OMA’s June 2008 Total Passenger Traffic Increases 3.1 Percent

                     Domestic Traffic Grows 3.5 Percent                 International Traffic Grows 1.2 Percent 

MONTERREY, Mexico, July 8, 2008 (PRIME NEWSWIRE) -- Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA, reports that total passenger traffic (terminal passengers) at its 13 airports increased 3.1% in June 2008, as compared to June 2007.

Domestic traffic in June 2008 increased 3.5% (+33,849 passengers), compared to the prior year period. The airports that reported the most significant growth in passenger traffic were Acapulco, Tampico, Monterrey, and Zihuatanejo, as a result of an increase in frequencies and a higher occupation rate on some domestic flights, particularly those to and from Toluca and Mexico City. The airports in Durango, San Luis Potosi, Torreon, and Mazatlan registered reductions, in large measure because of reduced frequencies on some routes and the cancellation of other routes.

International traffic increased 1.2% (+2,073 passengers) in June 2008, as compared to June 2007. Airports in Durango, Tampico, Monterrey, San Luis Potosi, Chihuahua, Torreon, and Acapulco showed growth, principally as a result of international routes opened in recent months. Airports in Culiacan, Mazatlan, Zihuatanejo, and Zacatecas recorded reductions in international traffic, as a result of a cancellation of routes by U.S. carriers and a reduction in frequencies on some scheduled international routes.

The continued increase in international oil prices has caused the cancellation of routes, reduction in flight frequencies, tariff adjustments, and other actions by the airlines, all of which affects traffic growth.
