OMA Reports February 2010 Traffic

MONTERREY, Mexico, March 9, 2010 (GLOBE NEWSWIRE) -- Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (Nasdaq:OMAB) (BMV:OMA), reports that terminal passenger traffic at its 13 airports decreased 12.5% in February 2010, as compared to February 2009. Domestic traffic decreased 13.4%, and international traffic decreased 8.7%.

Of total traffic, 97.4% was commercial aviation, and 2.6% was general aviation.

­Domestic traffic grew at three airports. Chihuahua and Culiacán traffic benefitted from increases on the routes to Guadalajara. Traffic in San Luis Potosí increased because of growth on the Monterrey route.

Domestic Traffic decreased in all other airports. The Monterrey, Acapulco, and Tampico airports had the largest traffic reductions; traffic reductions on the Mexico City route were the most important factor. The suspension of Aviacsa (suspended since July 6, 2009) also affected all three airports; in addition Acapulco and Tampico traffic were affected by a reduction in traffic carried by Interjet.

International traffic recorded growth at four airports. Noteworthy was the growth in traffic at the Zacatecas airport on its route to Los Angeles. The Tampico, Durango, and Chihuahua airports grew traffic on their routes to Houston.

The airports that had the largest reductions in international passenger traffic were the tourist destination airports. Acapulco and Zihuatanejo were affected by a decrease in charter traffic; Mazatlán was affected by reductions on the routes to Los Angeles and Houston.

The total number of flight operations (takeoffs and landings) in the month decreased 0.9% as compared to the prior year period.
