Captain Rogelio Castillo National Airport — Celaya, Mexico

The code CYW belongs to Captain Rogelio Castillo National Airport, a modest airfield serving Celaya in Mexico's Bajío region, Guanajuato state. Celaya is a mid-sized industrial and agricultural city known for its confectionery industry and manufacturing base, and CYW primarily handles general aviation, flight training, and light domestic traffic rather than scheduled airline service. Most travelers heading to or from Celaya instead use the larger Del Bajío International Airport near León, which offers connections across Mexico and the United States. CYW's runway and facilities remain modest, reflecting its role as a secondary regional airfield supporting private pilots, agricultural aviation, and occasional charter flights within Guanajuato's fertile central plateau.
