Monterrey, Mexico, February 9, 2009—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 10.5% in January 2010, as compared to January 2009.

Domestic traffic grew at four airports: Culiacán, +9.1%; Zacatecas, +5.3%; San Luis Potosí, +2.5%, and Durango, +0.8%. Culiacán traffic benefited from the performance of VivaAerobus, Interjet, and Grupo Mexicana. Grupo Aeroméxico led growth in San Luis Potosí and Zacatecas. Zacatecas and Durango also benefited from an increase in general aviation.

These factors were offset principally by the suspension of Aviacsa (suspended since July 6, 2009) and the reduction in traffic on Interjet and Grupo Aeroméxico. The Monterrey, Acapulco, Zihuatanejo, and Ciudad Juárez airports had the largest traffic reductions.

International traffic recorded growth at five airports. Noteworthy were the growth in traffic at the Zacatecas airport (+20.7%) on its routes to Los Angeles and Chicago, and at the Durango airport (+53.2%) on its routes to Houston and Chicago.

The airports that had the largest reductions in international passenger traffic were Zihuatanejo, Acapulco, and Mazatlán, where the common factor was a decrease in charter traffic, and Monterrey which was affected by a reduction in traffic to and from Houston along with the Aviacsa effect.

The total number of flight operations (takeoffs and landings) in the month increased 0.6% as compared to the prior year period.
