Chanute Martin Johnson Airport

Chanute Martin Johnson Airport (KCNU) is a medium airport in Chanute, KS. Pilots and dispatchers reference it by ICAO code KCNU or IATA code CNU. It sits in North America.

Chanute Martin Johnson Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 4,254-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 4,254 ft (1,297 m), a light-jet-class field. Representative aircraft that operate comfortably here include the Phenom 300, Citation CJ4, and Learjet 75. In practice this limits operations to light jets, turboprops, and short-field-capable aircraft.

Chanute Martin Johnson Airport lies at 1,002 ft elevation.

Local operations run on America/Chicago. Without scheduled airline traffic, the field tends to be quieter and more flexible for charter and corporate operations — a useful characteristic for early morning, late night, or short-notice flights that would be impractical at a hub.

SkyAccess inventory for KCNU updates continuously as operators publish new empty legs and one-way repositioning trips. Pricing on each leg is available with a free account, and an inventory alert will email you the moment a leg appears on the route you care about.

Regional fields like KCNU are a meaningful share of US private aviation — closer to the trip's actual origin or destination than the nearest major hub, with shorter ramp-to-cabin times that are the main reason owners and brokers prefer them.

Chanute Martin Johnson Airport is a city-owned airport located two miles southwest of Chanute, in Neosho County, Kansas. It is named for Martin Johnson, of the husband-and-wife explorers Martin and Osa Johnson, although it was Osa and not Martin who was native to Chanute.
