Antonio B. Won Pat International Airport (GUM)

Antonio B. Won Pat International Airport functions as a single terminal with arrivals on the ground floor and departures upstairs. A central check-in hall feeds two concourses: the west side (gates 1–5) handles many regional routes while the east pier (gates 7–20) serves most long-haul flights. Walking from ticketing to the far end of the east pier takes about 10–12 minutes, and moving between the end gates of each pier is roughly a seven- to eight-minute stroll through the central spine. TSA security sits mid-terminal at the entrance to the concourses, with additional document checks for certain carriers near the gates. Evening and late-night departure banks toward Japan and Korea can create 20–35 minute queues; midday windows often see 10–20 minute waits. Transfer passengers from regional flights must re-clear security before proceeding airside. All arrivals route directly into U.S. Customs and Border Protection for immigration prior to baggage claim. Processing times commonly range from 15–40 minutes depending on the number of widebody arrivals, followed by agriculture screening and customs x-ray in the exit hall. Passengers continuing to domestic U.S. points re-screen with TSA on the departures level; inter-island connections to Saipan and other Marianas destinations follow the same arrival flow before check-in. Airside amenities include the United Club and Sagan Bisita Lounge near the central gate area, DFS duty-free shops in both departures and arrivals corridors, and a mix of eateries offering local Chamorro plates, noodle bowls, coffee, and grab-and-go snacks. Landside services cover currency exchange, ATMs, travel essentials, car-rental desks, and ride-hailing pick-up zones just outside the arrivals canopy. Accessibility features range from elevators and ramps connecting all levels to wide corridors with wheelchair-friendly flooring and priority seating near each gate; airlines coordinate escort service when booked in advance. Family needs are supported by nursing rooms near Gates 12/13, changing tables in most restrooms, and a small children’s play corner by Gate 9 to occupy kids before boarding.
