Terminal passengers: includes passengers on the three types of aviation (commercial, charter, and general aviation), and excludes passengers in transit.

Domestic traffic grew at the Culiacan, Durango, and Mazatlan airports by 14.8%, 7.7%, and 7.0%, respectively. The performance of VivaAerobus, Aeromar, and Grupo Aeromexico were noteworthy. VivaAerobus opened the Mazatlan-La Paz route on October 1 and Reynosa-Veracruz on October 2.

Aeromar opened the Monterrey-San Luis Potosi route on October 5. These factors were offset by the suspension of Aviacsa (suspended since July 6, 2009), the departure from the markets of Alma and Aladia, and a reduction in traffic on Interjet and Magnicharter. The Monterrey, Acapulco, and Ciudad Juarez airports had the largest traffic reductions.

International traffic decreased principally because of the cancellation of international routes by Continental, Grupo Aeromexico, and Alaska Airlines, in addition to the suspension of Aviacsa. The Monterrey, Mazatlan, Acapulco, and San Luis Potosi airports were the most affected. On the other hand, international traffic at Zacatecas increased 22.6% as a result of growth on traffic on the Chicago, Oakland, and Los Angeles routes.

The total number of flight operations (takeoffs and landings) in October 2009 decreased 8.6% as compared to October 2008.
