MONTERREY, Mexico, Jan. 9, 2008 (PRIME NEWSWIRE) -- Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (Nasdaq:OMAB), reports that total passenger traffic (terminal passengers) at its 13 airports was 1.3 million in December 2007, an increase of 12.9% compared to December 2006.

Domestic traffic in December 2007 totaled 1,012,991 passengers, an increase of 16.2% compared to the prior year. Eleven of our airports reported growth in domestic passenger traffic as a result of new routes opened by the new airlines (Aladia, Alma, Avolar, Interjet, VivaAerobus, and Volaris). During December, Avolar opened the Durango-Puebla route and Alma began the Monterrey-Chihuahua route. Passenger traffic at the Zacatecas airport decreased 27.4%, as a result of the suspension of operations of Lineas Aereas Azteca on March 26, 2007, and the beginning of proceedings to revoke its concession, announced on October 10, 2007.

International traffic totaled 232,126 passengers in December 2007, a 0.6% increase compared to December 2006. The Culiacan, Chihuahua, San Luis Potosi and Monterrey airports recorded the most significant increases, as a result of the increase in frequencies and opening of international routes. During December, Mexicana opened the San Luis Potosi-Chicago and Monterrey-San Antonio routes. International passenger traffic at the Acapulco, Mazatlan and Zihuatanejo airports was affected by a reduction in charter and seasonal flights.
