Antonio B. Won Pat International Airport, named after Guam's first delegate to the U.S. Congress, has served as the primary aviation hub for Guam and the broader Micronesian region since its establishment in the post-World War II era. Situated near the capital Hagåtña, it handles a significant volume of leisure and business travelers connecting Asia, the U.S. mainland, and the Pacific islands. As the busiest airport in Micronesia, it plays a critical economic and logistical role for an island territory that depends heavily on air access.
- Terminal A — Handles international arrivals and departures, including major carriers from Japan, Korea, and the U.S. mainland, with duty-free retail and dining options.
- Terminal B — Serves regional and commuter operations connecting Guam to neighboring Micronesian island destinations.
- Taxi services available at the arrivals curb outside the terminal
- Rental car counters from major agencies including Hertz, Avis, and Budget
- Hotel shuttle buses operated by major resort properties in Tumon Bay
- Rideshare-style app-based services available on island
- Private transfer and tour company pickups by arrangement
- Hilton Guam Resort & Spa
- Hyatt Regency Guam
- Dusit Thani Guam Resort
- Sheraton Laguna Guam Resort
- Hotel Nikko Guam
Inside the terminal, travelers will find a modest selection of quick-service restaurants, a coffee shop, and snack outlets suited for pre-departure meals. Tumon Bay, the island's main tourist and resort strip located a short drive away, offers a wide range of dining from local Chamorro cuisine to Japanese and Korean restaurants catering to the island's international visitor base. Arriving early allows time to explore terminal food options, though choices expand significantly once you reach the resort district.
- Guam operates on Chamorro Standard Time (UTC+10), which is ahead of most U.S. departure cities by 15–17 hours — adjust plans accordingly.
- U.S. citizens do not need a passport to travel to Guam, but many international visitors benefit from the Guam-CNMI Visa Waiver Program — confirm eligibility before travel.
- Tumon Bay resorts are roughly 10–15 minutes by taxi from the airport and are the main accommodation hub for most visitors.
- Duty-free shopping is available both in the terminal and at dedicated shops throughout Tumon, with favorable pricing on cosmetics, alcohol, and electronics popular among Asian visitors.
