MONTERREY, Mexico, Dec. 5, 2012 (GLOBE NEWSWIRE) -- Mexican airport operator Grupo Aeroportuario del Centro Norte, S.A.B. de C.V., known as OMA (Nasdaq:OMAB) (BMV:OMA), reports that terminal passenger traffic at its 13 airports increased 8.3% in November 2012, as compared to November 2011. Domestic traffic increased 9.2%, and international traffic increased 2.5%.
