Spirit of St Louis Airport

Spirit of St Louis Airport (KSUS) is a medium airport in St Louis, MO. Pilots and dispatchers reference it by ICAO code KSUS or IATA code SUS. It sits in North America.

Spirit of St Louis Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 7,486-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 7,486 ft (2,282 m), a heavy-class field. Representative aircraft that operate comfortably here include the Gulfstream G550, Falcon 7X, and Bombardier Global 5500. In practice this most heavy and super-midsize jets operate here without restriction.

Spirit of St Louis Airport sits near sea level at 463 ft.

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 currently tracks 5 departing and 4 arriving private-jet legs at KSUS across the next six months of operator inventory. 25 aircraft from 10 operators are based here or fly through regularly, so most empty-leg supply originates from a local fleet rather than out-of-town repositioning.

Regional fields like KSUS 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.
