About this airport

Welcome

Antonio B. Won Pat International Airport, better known as Guam Airport (GUM), offers a unique travel experience more akin to a bustling Pacific transit station than a standard U.S. terminal. Waves of late-night flights from Japan, Korea, Micronesia, and Hawaii converge in its compact Main terminal. Over 3.7 million passengers pass through this gateway annually, creating a lively yet tightly coordinated environment shaped by a strong military presence and geared towards East Asian tourists and island hoppers.

At a glance

Situated just 6 kilometers northeast of Hagåtña, GUM hosts a single terminal that acts as a crucial hub for United Airlines. The airport features two runways, supporting both commercial and military aviation. Despite its small size, the airport handles a large volume of nighttime international flights, with passenger experience ranging from leisurely island-paced to hurried and crowded during peak hours.

Terminals & layout

The Main terminal serves all airlines, including United Airlines, Japan Airlines, and Korean Air. This single-terminal setup simplifies navigation but also means congestion can peak during late-evening flights, especially from 10 PM to 2 AM when many long-haul departures occur. The terminal includes various gates connected by concourses lined with restaurants, shops, and lounges, suitable for both quick layovers and longer waits.

Getting to and from the city

Transportation from GUM to downtown Hagåtña and the main tourist area of Tumon is primarily by taxi, with fares ranging from $15 to $25 for the 15-minute journey. For budget-conscious travelers, arranging a hotel shuttle in advance can be a cost-effective alternative. Although taxis are convenient, they're considered pricey for the short distance, especially when shuttles or shared rides can cut costs significantly.

Traveller essentials

The airport offers basic amenities, but frequent flyers advise downloading entertainment beforehand due to the notoriously unreliable Wi-Fi. Secure offline files if you need to work, as connectivity can struggle during busy periods. Parking options include Public Parking Lot and West Arrival Parking, both charging $10–$15 per day. For peace of mind, plan for longer processing in customs and security during peak arrival and departure times.

Dining & shopping highlights

The dining landscape at GUM is dominated by recognizable chains like Burger King, KFC, and Subway. Island Fiesta and UCC Café provide some local flair. Food service can be inconsistent, often thinning out during late-morning to mid-afternoon lulls when some outlets may close. Shopping includes Lotte and DFS Duty Free, with locals valuing the duty-free stores for Guam-branded snacks and East Asian cosmetics at competitive prices.

Lounges

The airport features six lounges, including Sagan Bisita and United Club, all situated in the Main terminal. These lounges reflect a mix of traveler types, from business professionals to military personnel. However, note that during peak hours, space can become limited, particularly with heavy late-night traffic.
