Servicing the U.S. territory of Guam, Antonio B. Won Pat Guam International Air Terminal welcomes visitors to the westernmost island “Where America’s Day Begins”. Known as the Gateway to Micronesia, the former military airfield services Asian countries such as Korea, Singapore, Japan and Thailand, and offers flights to Australia and American cities such as Honolulu and Los Angeles. As a territory of the United States, entry and visa requirements for the Guam airport are dictated by The United States Customs and Border Protection Agency.

The airport sits in both Tamuning and Barrigada, about four kilometres from Guam’s capital city of Hagatna, and three kilometres from numerous hotels along Tumon Bay. Guam tourism, luxury shopping and outdoor activities captivate visitors in Tumon Bay, who flock to one of the world’s largest tunnel aquariums and traditional ice shows and fire dances. Nightclubs and Vegas-style attractions go over-the-top at night with exotic animal and magic shows, while the calmer daytime hours reveal pristine wildlife-preservation beaches.

A passenger’s lounge and retail, food, duty-free and beverage outlets cater to passengers awaiting inward and outward-bound flights, and currency exchange booths are readily available. Rental car agencies operate directly from the airport, major international companies such as Hertz, Budget and Avis, and more than a dozen tour-group counters dot the airport. It’s easy to grab a taxi outside the West Arrival terminal building, with flat rates to major hotels and resorts in Guam, and to Andersen Air Force Base and the Naval Hospital.

The airport is named after Antonio Borja Won Pat, the first Guam native to sit in the United States House of Representatives. The airport’s history as a military airfield ties into the conflicts over Japanese defence of the Mariana Islands, World War II bombardments by the United States Army Air Forces Seventh Air Force, and its post-war reincarnation as the Naval Air Station Agana. The Government of Guam's Department of Commerce took over the operation as a civilian airport in 1969.
