MONTERREY, Mexico, April 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 7.7% in March 2008, as compared to March 2007. For the first quarter of 2008, total traffic increased 11.5%, as compared to the same period of 2007.

Domestic traffic in March 2008 increased 9.5% (+94,376 passengers), compared to the prior year period.

International traffic increased 1.9% (+5,721 passengers) in March 2008, as compared to March 2007. International traffic rose in Monterrey, Chihuahua, Culiacan, Torreon, San Luis Potosi, and Zacatecas as a result of increased frequencies on some routes. The principal decreases were in the tourist destination airports (Acapulco, Mazatlan, and Zihuatanejo) where the Holy Week vacation period did not stop the declining trend of recent months and the continued reduction of both scheduled and charter flights. International traffic in the first quarter decreased 2.0%.

By airport

Monterrey, OMA's principal airport, served 604,467 passengers in March 2008, an increase of 9.0% (+40,704 passengers) compared to the same month of 2007. Domestic traffic at Monterrey airport increased 7.6% as a result of the effect of the growing volume of passengers served by the new airlines, which was offset in part by fewer business passengers during the Holy Week vacation period and by a reduction in passengers carried by Aviacsa. International traffic rose 17.6% as a result of increased frequencies on routes to Los Angeles, San Antonio, and Las Vegas.

Traffic at Culiacan and Ciudad Juarez grew 30.6% and 27.2%, respectively. The airlines that started operating at these airports in 2007 have contributed significantly to their growth.
