Chuuk International Airport, designated IATA code TKK and ICAO code PTKK, is located on Weno Island in Chuuk State, part of the Federated States of Micronesia. It is the primary air gateway to the Chuuk Lagoon, one of the world's most celebrated wreck-diving destinations, where dozens of Japanese vessels sunk during World War II Operation Hailstone in 1944 lie on the seafloor. The airport serves both domestic inter-island routes within the Federated States of Micronesia and international connections, linking Chuuk to Guam and other Pacific island destinations. Due to its remote location in the western Pacific, air travel is the principal means of reaching the island from outside the region. The facility is a modest, single-terminal airport reflecting the relatively small population and visitor volume of Weno Island. It plays a critical economic role for Chuuk State by enabling the dive tourism industry that draws visitors from around the world.
