Domestic traffic increased at eight airports. Growth at the Chihuahua, Tampico, Zacatecas, Acapulco, and Mazatlan airports was noteworthy. In Chihuahua, traffic grew on the routes to Mexico City (where Interjet and Click Mexicana opened routes) and Guadalajara. Tampico traffic grew on the routes to Monterrey and Mexico City. Traffic growth in Zacatecas was principally the result of increased traffic on the Tijuana route. In Acapulco, traffic increased on the routes to Mexico City (where Interjet opened a route) and Guadalajara. Mazatlan traffic grew on the routes to La Paz and Guadalajara. Traffic at the other five group airports decreased.

During the month of July, VivaAerobus opened the Monterrey-Tuxtla Gutierrez route, and Interjet opened the Zihuatanejo-Mexico City route.

International traffic increased at nine airports, with Monterrey, Zacatecas, San Luis Potosi, Acapulco, and Mazatlan showing noteworthy increases. Monterrey benefitted from an increase in traffic to Houston, principally because of the opening of new routes by VivaAerobus and Aeromexico Connect. Zacatecas increased traffic on the route to Los Angeles. San Luis Potosi benefitted from an increase in passenger traffic to Dallas. Acapulco traffic increased on the Phoenix route, while Mazatlan traffic rose on the routes to Houston and Phoenix. International traffic decreased most in the Chihuahua and Torreon airports.
