Gateway to Kosrae, Micronesia's unspoiled island paradise.

Location
Okat, Federated States of Micronesia
Kosrae International Airport (IATA: KSA, ICAO: PTSA) serves Kosrae State, the easternmost state of the Federated States of Micronesia. Located near the village of Okat on the northern coast of Kosrae Island, the airport is the sole air entry point to this remote and ecologically rich island in the western Pacific Ocean. The airport features a single runway and limited facilities befitting its small population base and low passenger volumes. It primarily handles regional turboprop and jet service connecting Kosrae to other Micronesian islands and to Honolulu. The facility is vital for supplying the island with goods and connecting its roughly 6,000 residents to the wider region. Kosrae is renowned for its pristine coral reefs, mangrove forests, and ancient stone ruins at Lelu, and the airport serves as the starting point for eco-tourists and divers visiting the island. Despite its modest infrastructure, the airport plays a critical role in the economic and social life of Kosrae State.
Terminals
The airport has a single small terminal building handling both arrivals and departures with basic passenger amenities.
Getting to & from
Taxis and rental vehicles are the primary ground transportation options connecting the airport to Lelu and other parts of Kosrae Island.
