OMA’s October 2008 Total Passenger Traffic Decreases 10.5 Percent; Year to Date Traffic Increases 1.6 Percent

MONTERREY, Mexico, Nov. 7, 2008 (GLOBE 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 decreased 10.5% in October 2008, as compared to October 2007.

Domestic traffic in October 2008 decreased 10.1% (-101,022 passengers) compared to the prior year period. Traffic at Durango, Mazatlan, Ciudad Juarez, Culiacan, Torreon, Chihuahua, and Monterrey were affected principally by the cancellation of frequencies by Aviacsa and VivaAerobus, the suspension of Aerocalifornia, and the departure of Avolar from OMA's airports. The reduction in traffic in San Luis Potosi was principally the result of a reduction in frequencies by Click Mexicana and a decrease in general aviation. The airports in Reynosa, Acapulco, and Zacatecas increased domestic traffic, principally as a result of increased activity on the part of Volaris, Alma, Interjet, and Click Mexicana. The start of operations on October 22, 2008 of Volaris in Chihuahua with a route to Toluca was noteworthy.

International traffic decreased 12.9% (-20,789 passengers) in October 2008, as compared to October 2007. The airports of Monterrey, Mazatlan, Zihuatanejo, Zacatecas, and Culiacan were the most affected, principally as a result of a reduction in frequencies and cancellation of routes by some U.S. carriers and the departure of Delta from some airports.

On October 21, 2008, the charter airline Aladia announced the suspension of its operations as a result of the difficult business environment facing the air transport industry, together with the International economic and financial crisis. This airline carried 1.4% of OMA's total passenger traffic for the first 10 months of 2008.

By airport

Monterrey, OMA's principal airport, served 506,815 passengers in October 2008, a decrease of 9.3% (-51,734 passengers) compared to the same month of 2007. Domestic traffic at Monterrey airport decreased 9.3%, principally as a result of a lower volume of traffic on Aviacsa and the cancellation of some routes by VivaAerobus. International traffic decreased 8.8%, affected by a reduction in flight frequencies by Continental and a reduced load factor on American Airlines.

Acapulco, OMA's third largest airport, recorded growth of 10.0% in October. Domestic traffic increased 11.5% as a result of an increase in passenger traffic to and from Toluca, Mexico City, and Tijuana. International traffic decreased 1.4%, principally because of a reduction in traffic to Houston and Phoenix.

The Reynosa airport continued to generate positive results. October total passenger traffic increased 19.1%, largely because of Volaris, Click Mexicana, and Alma.
