Yap International Airport — Yap Island, Micronesia

Yap International Airport, known by the code YAP, is the sole air link for Yap State in the Federated States of Micronesia, a cluster of volcanic and outer reef islands in the western Pacific. A single runway handles the airport's limited but essential schedule, with United Airlines providing the primary connection to Guam and, on many routings, onward to Palau. Yap itself is unusual among Pacific islands for its hilly, volcanic terrain rather than a low coral atoll, and it remains famous for traditional stone money, huge carved limestone discs once used as currency and still honored in local custom. Divers are drawn to the surrounding waters for regular manta ray sightings. Because commercial flights are infrequent, the airport operates at a modest scale, yet it remains the primary gateway for tourism, government travel, and supplies reaching this remote island community.
