Antonio B. Won Pat International Airport: what's nearby, how to get there and when to go · 2026
Residents traveling on and off the island pass through this single commercial airfield, making its terminal schedules and transpacific flight links a constant factor in long-term planning.
Commercial aviation on Guam centers entirely on Antonio B. Won Pat International Airport, connecting the territory across the Pacific.
The airfield stands across the municipalities of Tamuning and Barrigada as the territory's sole international portal. Built during wartime and later expanded from a naval air station into a civilian transport center, the facility handles passenger movements and air cargo across the western Pacific. United Airlines operates a primary passenger hub here, while Asia Pacific Airlines maintains its central freight base on the site.

Civilian aviation evolved from a military Quonset hut after defense travel restrictions ended, eventually transferring control from naval authorities to the local airport agency. Modern operations include dedicated international arrival corridors designed to segregate inbound travelers from departing crowds in compliance with federal aviation security standards, streamlining passenger processing through updated security checkpoints.
Flight networks connect the island to destinations across Asia and the Pacific, including Honolulu, Tokyo, Manila, and Seoul. For temporary residents and long-term workers, reliance on this lone airport means off-island supply chains, mail transit, and emergency evacuations depend entirely on scheduled carrier routes, making airfield operations integral to daily life on the island.
