KGMU is the ICAO code for Greenville Downtown Airport (IATA GMU), located in Greenville, SC.
Greenville Downtown Airport (KGMU) is a medium airport in Greenville, SC. Pilots and dispatchers reference it by ICAO code KGMU or IATA code GMU. It sits in North America.
Greenville Downtown Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 5,393-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.
The longest runway measures 5,393 ft (1,644 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.
Greenville Downtown Airport lies at 1,048 ft elevation.
Local operations run on America/New_York. 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 currently tracks 108 departing and 124 arriving private-jet legs at KGMU across the next six months of operator inventory. 6 charter operators have run trips through this field in our recent inventory window.
Regional fields like KGMU 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.
