Lewistown Municipal Airport

Lewistown Municipal Airport (KLWT) is a medium airport in Lewistown, MT. Pilots and dispatchers reference it by ICAO code KLWT or IATA code LWT. It sits in North America.

Lewistown Municipal Airport is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 6,100-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 6,100 ft (1,859 m), a midsize and super-midsize-class field. Representative aircraft that operate comfortably here include the Citation Longitude, Challenger 350, and Gulfstream G280. In practice this comfortable for most midsize and super-mid charter equipment.

Lewistown Municipal Airport sits at 4,170 ft above sea level. Hot-and-high conditions can meaningfully reduce takeoff performance in summer — planners should factor density altitude into payload and fuel decisions.

Local operations run on America/Denver. 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 36 departing and 28 arriving private-jet legs at KLWT across the next six months of operator inventory. 3 charter operators have run trips through this field in our recent inventory window.

Regional fields like KLWT 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.

Lewistown Municipal Airport is two miles southwest of Lewistown, in Fergus County, Montana. It is owned by the city and county.
