Miley Memorial Field

Miley Memorial Field (KBPI) is a medium airport in Big Piney, WY. Pilots and dispatchers reference it by ICAO code KBPI or IATA code BPI. It sits in North America.

Miley Memorial Field is a regional airport primarily serving general aviation, charter, and corporate flight departments. The 6,803-foot runway means it is well-suited as a dedicated bizjet field, free from airline scheduling pressure.

The longest runway measures 6,803 ft (2,074 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.

Miley Memorial Field sits at 6,990 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 86 departing and 43 arriving private-jet legs at KBPI across the next six months of operator inventory. 4 charter operators have run trips through this field in our recent inventory window.

Regional fields like KBPI 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.
