John Glenn Columbus International Airport

John Glenn Columbus International Airport (KCMH) sits 6 miles east of downtown Columbus, Ohio. The field handles significant commercial service (Southwest, Delta, American, United, JetBlue, Frontier, Spirit, Allegiant) and a meaningful flow of business aviation, particularly driven by the substantial Columbus corporate community (Nationwide Insurance, JPMorgan Chase Columbus operations, L Brands HQ, AEP, Cardinal Health, Big Lots), Ohio State University, and the state-capital government flow.

The two runways at KCMH (10R/28L 10,701 ft, 10L/28R 8,000 ft) handle every current business jet without restriction. Three FBOs (Atlantic Aviation, JetExpress, and OSU Airport) handle business movements. Field elevation is 815 feet, no density-altitude concerns. The dominant operational considerations are Ohio Valley winter weather (snow, freezing rain), summer thunderstorms, and the structural OSU football traffic — for every home game KCMH handles concentrated bizjet inbound flow that drives ramp pressure. The Memorial Tournament golf event in Dublin (May) is another structural peak. Ground time to downtown Columbus is 10–15 minutes; OSU campus is 20; Dublin / Powell corporate corridor is 25–35.

John Glenn Columbus International Airport is an international airport located 6 miles (9.7 km) east of downtown Columbus, Ohio. It is managed by the Columbus Regional Airport Authority, which also oversees operations at Rickenbacker International Airport and Bolton Field. The airport code "CMH" stands for "Columbus Municipal Hangar", the original name of the airport.
