Antonio B. Won Pat International Airport

Antonio B. Won Pat International Airport is the principal airport of Guam and the busiest airport in Micronesia, handling roughly 3.5 million passengers annually in pre-pandemic normal years. GUM's strategic significance far outstrips its passenger count: Guam is a US territory in the Western Pacific, 2,400 mi (3,860 km) from Honolulu, and GUM sits adjacent to Andersen Air Force Base, making the island one of the most militarily significant pieces of US territory in Asia. The airport is the de facto hub of the US Pacific aviation network outside Hawaii, and its 12,000-ft (3,660 m) runway can accommodate any aircraft in scheduled commercial service. GUM is a hub for United Airlines, a legacy of the former Continental Micronesia operation that merged into United in 2010. United operates an island-hopper service from GUM to Honolulu via Majuro, Kwajalein, Kosrae, Pohnpei, and Chuuk — the only scheduled service linking many of the smaller Federated States of Micronesia and Marshall Islands to the outside world, and one of the most distinctive remaining scheduled routings in the global network. International carriers Korean Air, Jeju Air, T'way, Jin Air, and Japan Airlines, All Nippon, Peach, T'way, Jetstar Japan, and United operate substantial Japanese and Korean inbound leisure traffic; China Airlines serves Taipei. Philippines AirAsia provides Manila service. GUM is named for Antonio Borja Won Pat, Guam's first elected delegate to the US Congress. A single runway, 06L/24R, measures 12,015 ft (3,662 m); a parallel military runway is used by Andersen AFB across the island. The airport's civilian terminal has been significantly expanded, with 10 jet bridges serving domestic (US) and international traffic in separated concourses — a split necessary because US-mainland arrivals at GUM are technically 'pre-cleared' domestic, while international arrivals face US customs.
