Chuuk International Airport — Weno Island, Micronesia

Chuuk International Airport, marked by the code TKK, sits on Weno Island within Chuuk Lagoon, part of the Federated States of Micronesia in the western Pacific, and functions as the gateway to one of the world's most renowned wreck-diving destinations. The lagoon surrounding the airport holds the remains of dozens of Japanese naval and merchant vessels sunk during a major American air raid in 1944, an operation that left behind an extraordinary underwater museum now explored by scuba divers from around the globe. TKK connects Weno to Guam and other Micronesian islands through limited but essential air service, since the remote, scattered geography of the Federated States makes sea travel between islands slow and impractical for most visitors and residents alike. Beyond diving tourism, the airport supports the everyday needs of Chuuk State's population, handling government travel, medical evacuations, and cargo shipments to an island community with few other reliable transport links to the outside world.
