Grupo Aeroportuario del Centro Norte S.A. de C.V. operates and manages 13 international airports in the north and central regions of Mexico. The company's airports serve Monterrey, M xico's third largest metropolitan area, the tourist destinations of Acapulco, Mazatlan, and Zihuatanejo, and nine other regional centers and border cities. Since its inception in 1998, the company has been focusing on quality aeronautical and commercial services to passengers, airlines and others customers, achieving high standards of management and generating solid financial performance. Since 2000, OMAB has had the support of two strategic investors with significant experience in the operation of infrastructure and airport services: Empresas ICA, Mexico's largest engineering, procurement and construction company and A roports de Paris, a leading European airport operator.

The company has two sources of revenue: aeronautical services and non-aeronautical services. Revenue from its aeronautical services is earned from passenger charges, landing charges, aircraft parking charges, charges for airport security services, and charges for the use of passenger walkways. The company's revenue from non-aeronautical services is earned from the leasing of space in its airports to airlines, retailers, and other commercial tenants access fees collected from third parties providing complementary services at its airports and related miscellaneous sources. The company's principal source of revenue remains passenger charges, which are collected from airlines for each passenger. Passenger charges are automatically included in the cost of a passenger's ticket and are generally collected twice monthly from each airline.
