Kosrae International Airport

Kosrae International Airport (PTSA) is a medium airport in Okat, Micronesia. Pilots and dispatchers reference it by ICAO code PTSA or IATA code KSA. It sits in Oceania.

Kosrae International Airport is a regional commercial airport that doubles as a busy private-aviation base. Operators benefit from full instrument approaches and an FBO infrastructure scaled for regular jet traffic, often without the congestion of the nearest major hub.

The longest runway measures 5,752 ft (1,753 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.

Kosrae International Airport sits near sea level at 11 ft.

Local operations run on Pacific/Kosrae. Scheduled airline service is light enough that it rarely interferes with charter movements, though planners should still expect to coordinate with the handling agent for international turnarounds.
