MONTERREY, Mexico, Aug. 13, 2010 (GLOBE NEWSWIRE) -- Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (Nasdaq:OMAB) (BMV:OMA) announced that it has ended the agreement for collection of passenger charges with the airlines of Grupo Mexicana, including Mexicana de Aviación, Click Mexicana, and Mexicana Link. This measure has been taken in order to protect future revenues as a result of developments in these airlines.

Effective August 21, 2010, these three airlines will either have to pay OMA in advance passenger charges for departing passengers at OMA airports or ask their passengers to make the payment directly in the airport prior to boarding, based on procedures that will be announced in the near future. OMA will work together with these airlines to make the payment process flexible and efficient for passengers.

This measure applies only to the airlines Mexicana de Aviación, Click Mexicana, and Mexicana Link. The agreements for the collection of passenger charges with other airlines continue unchanged.

The Grupo Mexicana airlines currently operate at the following OMA airports: Acapulco, Chihuahua, Culiacán, Durango, Mazatlán, Monterrey, Reynosa, Tampico, Torreón, and Zihuatanejo. For the first six months of 2010, the Grupo Mexicana airlines generated 12.2% of OMA's revenues, with Mexicana de Aviación accounting for 5.9%. Of the Ps. 458.8 million in accounts receivable on OMA's balance sheet as of June 30, 2010, the Grupo Mexicana airlines owed Ps. 99.8 million, including Ps. 49.5 million from Mexicana de Aviación; most of these receivables are for passenger charges.
