Guam International Airport (GUM), officially named Antonio B. Won Pat International Airport, serves as a critical Pacific Ocean hub connecting the United States territory of Guam to major destinations across Asia, Oceania, and the U.S. mainland. Located approximately 6 kilometers (4 miles) northeast of Hagåtña, the island's capital, the airport lies within the municipalities of Tamuning and Barrigada. With a single integrated passenger terminal, the airport caters to more than 3.6 million passengers annually, functioning as a strategic gateway for transpacific travel and a major hub for United Airlines' Pacific operations.

Guam International Airport Terminal Map and Layout

The passenger terminal at Guam International Airport follows a three-level linear design with a central atrium that gracefully blends modern functionality with traditional Chamorro architectural elements, including stylized latte stone motifs displayed prominently at the terminal's entrance. The terminal building encompasses approximately 550,000 square feet of floor space, providing ample room for passenger processing, retail, and airline operations.

The basement level houses all arrival facilities, including customs and immigration processing, baggage claim carousels, and the Hafa Adai Gardens. The apron level, which functions as the departure level, contains airline ticketing counters and check-in areas. The third floor features departure gates, immigration facilities for departing passengers, and administrative offices for the Guam International Airport Authority.

A unique architectural characteristic of Guam International Airport stems from its original design concept. Since all flights require customs or immigration inspection, the post-security concourse and gate area was not initially designed to separate arriving and departing passengers completely. The only normal passenger entrance is through security, and the only normal exit is through immigration. Semi-permanent movable walls now divide much of the concourse length into two halves, maintaining compliance with post-9/11 security requirements while preserving the terminal's operational efficiency. For connecting flights, most passengers will exit one gate and walk through the concourse area, which contains all gates in a single connected space. Walking between the farthest gates takes approximately 8 to 10 minutes.

Navigating Guam International Airport Terminals

Guam International Airport operates a single integrated terminal rather than separate terminal buildings. The concourse level contains all departure gates divided between a west concourse and an east concourse arrangement, with gates numbered sequentially. Moving walkways assist passengers traversing the longer stretches of the departure level, and clear bilingual signage in English and Japanese guides travelers throughout the facility.

Departures Level (Third Floor)
All airlines check in on the apron level, one floor below the departure gates. After clearing security screening, passengers ascend to the third-floor concourse where all gates, dining options, duty-free shopping, and lounges are located. United Airlines operates primarily from gates near the center and east sections of the concourse, while most international carriers use gates on the west concourse. The Lotte Duty Free store anchors the retail offerings on this level, operating 24 hours daily. Dining options include local Chamorro cuisine alongside familiar American fast-food chains.

Arrivals Level (Basement)
All arriving passengers, regardless of origin, descend to the basement level for processing through U.S. Customs and Border Protection. Baggage claim carousels sit adjacent to the customs inspection area. After clearing customs, passengers exit into the public arrivals hall where ground transportation options, including rental car counters and shuttle pickup points, are readily accessible.

Transportation to and from Guam International Airport

Navigating from Guam International Airport to your final destination requires some advance planning, as the island's public transportation infrastructure differs significantly from major mainland U.S. cities. Renting a car remains the most popular and practical option for visitors wanting to explore Guam's beaches, shopping districts, and cultural sites at their own pace.

Getting to and from Guam International Airport by Car

Guam International Airport sits along South Marine Corps Drive (Route 1), the island's primary north-south arterial road. The main airport entrance is on Chalan Pasaheru, which connects directly to Route 1. Traffic congestion can occur during peak morning hours (7:00 AM to 9:00 AM) and evening hours (4:00 PM to 6:00 PM), particularly around the Tamuning and Hagåtña areas. Allow an extra 15 to 20 minutes for travel during these periods.

The airport's parking lot, completed alongside the terminal expansion in the 1990s, offers approximately 710 parking spaces. Short-term parking is conveniently located directly in front of the terminal building, with rates averaging $3 per hour up to a daily maximum of approximately $15. Long-term parking sits adjacent to the short-term lot, with daily rates around $10 to $12. Payment is accepted via cash and major credit cards at automated pay stations. The parking lots are surfaced, well-lit, and patrolled regularly by airport police.

A cell phone waiting lot is available for drivers picking up arriving passengers. Located near the airport entrance on Chalan Pasaheru, this free waiting area allows you to park temporarily until your arriving party contacts you for curbside pickup. Wait times are limited to 30 minutes, and vehicles must remain attended at all times. Curbside drop-off at the departure level permits a maximum dwell time of 5 minutes; vehicles left unattended will be ticketed and may be towed.

Several hotels near the airport offer park and fly packages for travelers leaving the island for extended periods. These typically include one night's accommodation with up to 7 or 14 days of complimentary parking, providing a cost-effective alternative to long-term parking fees.

Getting to and from Guam International Airport by Rideshare or Taxi

Rideshare services operate differently on Guam compared to the U.S. mainland. While Uber and Lyft do not currently operate on the island, the local taxi industry remains robust and well-regulated. Taxi stands are located directly outside the arrivals hall on the basement level. Metered taxis serve the airport, with fares to Tumon hotels averaging between $15 and $25, a journey of approximately 10 to 15 minutes. Trips to Hagåtña cost around $12 to $18. Most drivers accept U.S. dollars in cash, and many also accept major credit cards, though it is advisable to confirm payment method before starting your journey. A small number of private sedan and van services operate by advance reservation, offering fixed-rate transfers to hotels and military bases.

Getting to and from Guam International Airport by Public Transportation

Public bus service is provided by the Guam Regional Transit Authority. The closest bus stop is on South Marine Corps Drive, approximately a 10 to 15-minute walk from the terminal along Chalan Pasaheru. Buses are limited in frequency and primarily serve commuters, making this option impractical for visitors with luggage. Most travelers arriving at Guam International Airport opt for rental cars, taxis, or pre-arranged hotel shuttles instead of public transit.

Key Amenities at Guam International Airport

ATMs

ATMs are located on the apron level near the check-in counters and on the third-floor concourse level near the departure gates. Machines dispense U.S. dollars and are operated by Bank of Guam and First Hawaiian Bank. A total of six ATMs are distributed throughout the terminal.

Lost and Found

The Guam International Airport Authority Airport Police manage lost and found services. The lost and found office is located on the basement level near the GIAA administrative offices. For inquiries about lost items, contact the Airport Police at (671) 646-0300 or visit the information desk on the departure level. Items found at security checkpoints are typically held by TSA for 30 days before being transferred to the general lost and found.

Luggage Services

Luggage carts are available at the arrivals area and departure curbside for a rental fee of approximately $4 per cart. There is no luggage storage or left-luggage facility at the airport due to security regulations. Luggage wrapping services are not currently available.

Pets

Pet relief areas are located outside the terminal building at both ends of the arrivals level. Service animals are permitted throughout the terminal. Travelers flying with pets should contact their airline directly for specific carrier requirements, health certificate documentation, and applicable fees, as regulations vary by carrier. Guam maintains strict quarantine regulations for animals arriving on the island.

Showers

Currency Exchange

Currency exchange services are limited at Guam International Airport. As Guam is a U.S. territory, the U.S. dollar is the official currency. Most international travelers arrive with U.S. dollars or withdraw cash from ATMs upon arrival. Currency exchange counters formerly operating near arrivals have been discontinued. Japanese yen are sometimes accepted at major hotels and shopping centers in Tumon, but the airport itself operates strictly in U.S. dollars.

Smoking Area

Guam International Airport is a smoke-free facility in all indoor areas. Designated smoking areas are located outside the terminal building at marked locations on the arrivals and departures curbsides. Smoking is strictly prohibited beyond security checkpoints, as no indoor smoking lounges exist post-security.

Complimentary WiFi is available throughout the terminal building. Connect to the "GIAA-Free-WiFi" network and accept the terms of service for unlimited free access. Charging stations with standard U.S. power outlets and USB ports are located near gate seating areas throughout the concourse level, with additional stations near the food court.

Other Amenities

Duty Free and Shopping at Guam International Airport

Duty-free shopping is available at Guam International Airport, operated by Lotte Duty Free. Located in the departure lobby on the third floor, the store operates 24 hours daily, 365 days a year, and accepts various international credit cards including JCB, Visa, Mastercard, and American Express. Guam's status as a U.S. territory with unique customs regulations permits duty-free allowances for departing passengers on most international flights. The store stocks a comprehensive range of international brands spanning cosmetics, fragrances, fashion accessories, watches, premium liquor, tobacco products, and Guam-exclusive souvenirs.

Shopping at Lotte Duty Free presents strong value, particularly for cosmetics and fragrances from Asian beauty brands alongside Western luxury names. Liquor prices are competitively priced compared to mainland U.S. retail, while exclusive travel-retail gift sets frequently offer substantial savings. The store accepts JCB coupons offering a 10% discount on purchases over $50, though certain premium brands and tobacco products are excluded from promotional discounts.

For local souvenirs such as Chamorro crafts, woven items, and locally produced cookies and candies, the airport offers a modest selection. However, Tumon's shopping centers and the Guam Premier Outlets typically provide wider variety and better pricing for general souvenirs. The airport is best for last-minute duty-free cosmetics, liquor, and chocolates.

Clear expedited security is not currently available at this airport. The busiest departure days are Thursday through Monday, with peak hours concentrated between 6:00 AM and 9:00 AM, and again between 5:00 PM and 8:00 PM, aligning with United Airlines' banked schedule for transpacific and regional island-hopper flights.

Guam International Airport Drop Off and Pick Up Information

A strict 5-minute dwell time applies to vehicles at the curb; unattended vehicles are ticketed and may be towed. No parking is permitted on the departure roadway. Arriving passengers are picked up on the basement level outside the baggage claim and customs exit. The arrivals pickup zone features designated lanes for private vehicles, taxis, and hotel shuttles. The free cell phone waiting lot on Chalan Pasaheru near the airport entrance provides a convenient staging area for drivers waiting for arriving passengers. Drivers should remain with their vehicles and enter the arrivals pickup zone only after their passenger confirms readiness at the curb.

Flight Routes and Airlines at Guam International Airport

United Airlines dominates operations at Guam International Airport, utilizing the facility as its primary Pacific Ocean hub. United operates an extensive network of regional island-hopper flights serving destinations across Micronesia, including Chuuk, Pohnpei, Kosrae, Kwajalein, and Majuro, along with the Honolulu-Guam route and direct services to Tokyo-Narita, Osaka, Nagoya, and Fukuoka. Philippine Airlines flies to Manila, while Korean carriers including Korean Air, Jeju Air, Jin Air, and T'way Air connect Guam to Seoul-Incheon and Busan. China Airlines operates service to Taipei. Seasonal charters occasionally serve Guam from additional Asian gateways. The island-hopper route, flown by United's Boeing 737 aircraft, is legendary among aviation enthusiasts for its unique stops across remote Pacific atolls.

Renting a car at Guam International Airport provides the ultimate flexibility for exploring the island's beaches, shopping, and cultural sites. Rental car counters are located in the arrivals hall on the basement level, adjacent to baggage claim. Major companies operating on-site include SIXT, which maintains a branch at 484 South Marine Corps Drive near the airport, Toyota Rent A Car (operating since 1914 as Guam's oldest rental company), and several local agencies. SIXT offers a diverse fleet including compact cars, sedans, sports cars, convertibles, and SUVs. Toyota Rent A Car operates a complimentary 24-hour shuttle service from the airport, departing every 15 minutes from the left exit of the arrivals lobby; they do not have a counter inside the terminal.

Popular vehicle types include compact economy cars for Tumon-area stays, midsize sedans for couples, and SUVs for families or those planning to explore Guam's southern beaches and more rugged terrain. Advance booking is strongly recommended, particularly during peak tourism seasons including Japanese Golden Week, summer months, and year-end holidays. Renting a car unlocks access to remote beaches, waterfall hiking trails, and the scenic coastal drives that define Guam's natural beauty. Fuel stations are abundant along Marine Corps Drive, with the closest station approximately half a mile south of the airport.

Long-term parking, suited for travelers leaving vehicles for multiple days, charges approximately $10 to $12 per day. Payment is accepted via cash and credit cards at automated pay machines located at the pedestrian exits. The parking lots are surfaced, fenced, illuminated, and patrolled by airport police. Electric vehicle charging stations are not currently available at the airport parking facilities, though charging infrastructure is expanding on Guam, with stations available at select Tumon hotels.

Places to explore near Guam International Airport

The airport's central location in Tamuning places visitors within easy reach of Guam's primary tourism district. Tumon Bay, famous for its white sand beaches and luxury resorts, lies just 10 minutes north, approximately 5 kilometers away with a drive time of 10 to 15 minutes depending on traffic. The capital city of Hagåtña sits 4 kilometers southwest, an 8-minute drive, featuring the Guam Museum, Latte Stone Park, and historic Spanish-era buildings.

For nature adventures, Ritidian Point in Guam's northernmost reaches offers pristine beaches and jungle trails, reachable in approximately 45 minutes.

Essential Travel Tips

U.S. citizens traveling to Guam from the mainland U.S. require only a valid government-issued photo ID, such as a driver's license, though a U.S. passport is recommended as flights may divert or transit through foreign territories. International visitors must possess a valid passport and may require a U.S. visa or ESTA authorization, as Guam is under U.S. jurisdiction. The Guam-CNMI Visa Waiver Program permits entry for nationals of select Asian countries under specific conditions.

Arrive at Guam International Airport at least 2 hours before international departures and 90 minutes before domestic island-hopper flights. Flight status updates are available on the airport website and through individual airline apps.

When searching for flights or reserving a rental car, entering GUM ensures you are booking services for the Antonio B. Won Pat International Airport in Tamuning.

The airport's full official name honors Antonio Borja Won Pat, Guam's first congressional delegate. You will see GUM printed on your boarding pass, luggage labels, and throughout travel itineraries when departing from or arriving on the island.

Guam Airport sits directly within Tamuning's municipal boundaries, so the distance to the core commercial area is approximately 1.5 to 2 miles. By car, the drive takes roughly 5 to 7 minutes under normal traffic conditions. The popular Tumon Bay hotel strip, also part of Tamuning, is slightly farther at about 3 miles, equating to a 10-minute drive. Given Guam's compact size and excellent road network, travelers should consider the airport centrally located. Whether you are heading to a business meeting near the ITC intersection or checking into a beachfront resort, you will spend minimal time in transit from GUM compared to larger international airports on the mainland.

Guam Airport operates a single, integrated passenger terminal building with separate areas designated for arrivals and departures on different levels. The lower level handles arriving passengers, baggage claim, and customs processing, while the upper level is dedicated to check-in counters and security screening for departing flights. Despite its single-terminal design, the facility is modern and spacious, efficiently managing both international and domestic United Airlines operations. The compact layout means you do not need to worry about inter-terminal trains or complex transfers. All airline gates, retail shops, and dining options are accessible within a short walking distance once you clear security and proceed to the concourse area.

United Airlines is the dominant carrier at GUM, operating a significant hub with frequent flights to Honolulu, Tokyo-Narita, Manila, and various Micronesian islands. Other major airlines serving Guam include Japan Airlines, Korean Air, EVA Air, Philippine Airlines, China Airlines, and Jin Air. Low-cost regional carriers such as Jeju Air and T'way Air also offer seasonal and scheduled services, primarily connecting Guam with South Korea. The route network caters heavily to the tourism market, with extensive connections to Japan and Korea. Domestic routes to the U.S. mainland are available via United's Honolulu gateway. Always verify current schedules, as regional airline service can fluctuate based on tourism demand and seasonal factors.

Yes, Guam Airport is a fully equipped international airport serving as the primary gateway to the U.S. territory of Guam. It handles direct flights from Japan, South Korea, the Philippines, Taiwan, China, and various Micronesian destinations. The facility maintains U.S. Customs and Border Protection services for all international arrivals, operating under the same federal security standards as mainland U.S. airports. For U.S. citizens, traveling to Guam requires no passport if arriving from another U.S. point, though a Real ID-compliant identification is mandatory. International visitors must possess valid passports and any applicable U.S. visas or ESTA authorization under the Guam-CNMI Visa Waiver Program, which allows entry for eligible nationalities without a standard U.S. visa.

The most convenient method is a taxi, which costs approximately $15 to $25 USD depending on your exact hotel location in Tumon Bay. The ride takes about 10 minutes. Many major hotels also offer complimentary shuttle services; you should confirm availability and pickup procedures with your accommodation before arrival. Public transit via the Guam Regional Transit Authority bus is limited, but the Tumon Shuttle does connect the airport to the hotel strip for around $3 USD per ride. If you prefer independence upon arrival, renting a car directly at the terminal is highly recommended, as Guam's road system is easy to navigate and parking is generally free at hotels and shopping centers.

Public bus service near Guam Airport exists, but it is not directly integrated into the terminal complex. The Guam Regional Transit Authority operates several bus routes, with the closest stops along Marine Corps Drive, approximately a 10-minute walk from the terminal entrance. The Tumon Shuttle service provides connections to the hotel district for around $3 USD per ride. However, luggage and the tropical heat can make walking to the bus stop challenging for many travelers. Most visitors prefer taxis, hotel shuttles, or rental cars for a seamless transition from the airport. If you are on a strict budget and traveling light, the public bus is functional but requires patience and precise timing.

Taxi fares from GUM to Tumon Bay hotels typically range between $15 and $25 USD, with the variance depending on the specific resort's distance from the terminal. A trip to central Tamuning locations costs slightly less, usually around $10 to $15 USD. Official airport taxis operate on a metered system, and you can find the taxi stand directly outside the arrivals level. Rides to the naval base or farther southern villages will cost more, generally $30 to $40 USD. It is advisable to confirm the estimated fare with the driver before departing. Most drivers accept cash in U.S. dollars, and a small number may accept credit cards, but carrying cash is strongly recommended.

Ride-hailing apps such as Uber and Lyft do not operate on Guam. The island relies entirely on traditional taxi services and hotel shuttles for metered transportation. You can find a dedicated taxi queue immediately outside the baggage claim area on the arrivals level. Stroll Guam, a locally developed app, sometimes offers private driver dispatch services, but availability varies significantly. Most visitors find that renting a car provides the best flexibility for exploring the island, as public transportation is limited and taxis cannot be summoned via app. If you plan to rely solely on taxis, save the contact number for a reputable local cab company before arrival.

GUM hosts a dedicated Rental Car Center directly adjacent to the terminal. Major on-site brands include Hertz, Budget, Avis, Enterprise, National, and local specialists like Nissan Rent a Car. Several other providers, including Dollar and Thrifty, operate shuttle-served facilities less than half a mile from the airport. Because Guam is a popular tourist destination with limited public transit, vehicle availability can be tight during holiday seasons and summer months. Booking in advance through a comparison platform is essential to secure your preferred vehicle type and the most competitive rate. Most companies offer unlimited mileage, and air conditioning is standard in nearly all rental fleets.

The consolidated Rental Car Center is located in the ground transportation area directly across from the passenger terminal. After exiting baggage claim, follow the clearly marked signs to the pedestrian walkway leading to the rental facility. The walk takes less than three minutes and is entirely covered, protecting you from sun and rain. Some off-airport rental agencies maintain desks inside the terminal and provide complimentary shuttle vans that pick up curbside. When returning your vehicle, look for Car Rental Return signs on the airport access road. The return lot is well-lit and located adjacent to the same facility where you picked up your car, streamlining the walk back to the departure level.

Yes, advance reservations are strongly recommended. Guam's tourism economy creates fluctuating demand, and peak travel periods such as Golden Week, Obon, summer vacation, and the Christmas holiday season can deplete rental fleets completely. Walk-up availability is rarely guaranteed, and last-minute rates are typically significantly higher. Booking online at least two weeks ahead allows you to compare rates and secure the vehicle class you actually need, whether a compact sedan for city driving or a larger SUV for exploring off-road beaches. Most comparison websites offer free cancellation options, so reserving early preserves your flexibility without financial risk.

You must present a valid driver's license. U.S. citizens can use a license issued by any state or territory. International visitors from most countries can rent using their home country license along with a valid passport. An International Driving Permit is not legally required for English-language licenses, but it can be helpful if your license uses non-Roman characters. You also need a credit or debit card in the primary driver's name for the security deposit. If using a debit card, be prepared for a larger hold on funds, and confirm with the rental company in advance. The minimum age to rent is typically 21, though drivers under 25 may incur an additional young driver surcharge.

The standard minimum rental age in Guam is 21 years old. However, renters between the ages of 21 and 24 are typically subject to a daily underage driver surcharge, ranging from approximately $15 to $30 USD per day depending on the rental company and vehicle class. Some specialty vehicle categories, including SUVs, premium sedans, and convertibles, may require the driver to be at least 25. Active-duty military personnel stationed on Guam can sometimes have the underage fee waived; you must present valid military orders and identification at the counter. Always check the specific age policy listed in the terms and conditions when booking, as they vary between providers.

Short-term parking in the lot directly opposite the terminal costs approximately $2 USD per hour, with a daily maximum around $12 to $14 USD. Long-term parking in the economy lot is priced at roughly $10 USD per day. Payment kiosks accept cash and major credit cards before you return to your vehicle. The parking facility is well-maintained and secured with regular patrols. Compared to major mainland U.S. airports, GUM parking is relatively affordable. If you are picking up a passenger and expect to wait less than 30 minutes, the cell phone waiting lot offers a free alternative. Always lock your vehicle and do not leave valuables visible inside.

Yes, GUM provides an economy long-term parking lot designed for travelers leaving their vehicles for several days or weeks. The daily rate is approximately $10 USD, making it a cost-effective option for short inter-island trips or longer mainland journeys. The lot is located a slightly farther walk from the terminal compared to the premium short-term spaces, but the distance is still manageable with luggage carts. Regular security patrols monitor the area. Given Guam's warm climate, it is wise to use a sunshade for your windshield and ensure all windows are fully closed. For extended absences, confirm your vehicle insurance and registration are current before departure.

The free cell phone waiting lot is situated directly along the airport entrance road, just before you reach the terminal curb. Follow the signs for 'Cell Phone Lot' immediately after turning off Route 10A. Drivers must remain with their vehicles at all times while waiting. Once your arriving passenger has collected their luggage and is curbside, you can drive forward to the arrivals pickup area in under a minute. This lot eliminates the need to circle the airport repeatedly or park in paid short-term spaces while waiting for a delayed flight. Idling or parking curbside in the active loading zone is prohibited, so use the lot to avoid fines.

Yes, the departure level upper roadway allows active curbside drop-off directly in front of the check-in hall doors. Porters are usually available to assist with luggage. For security reasons, unattended vehicles are strictly prohibited; you must remain with your car if you are not actively unloading. If you wish to accompany someone inside the terminal to check-in, you must park in the short-term lot. The curbside arrival pickup on the lower level operates similarly: drivers must stay with the vehicle until the passenger appears. Airport police regularly enforce the no-waiting policy to maintain smooth traffic flow and security, so plan your timing accordingly.

Yes, Guam Airport offers complimentary WiFi throughout the terminal building. Select the 'GUM Free WiFi' network from your device settings and accept the terms of use via the splash page. The connection speed is generally adequate for checking emails, browsing websites, and confirming flight or hotel details. Streaming high-definition video can be inconsistent during peak departure times due to bandwidth demand. Charging stations and power outlets are located near gate seating areas, allowing you to keep devices powered. If you need a more secure or faster connection, several airline lounges provide private WiFi for their guests. The free service covers both the pre-security and post-security areas.

GUM features the Sagan Bisita Lounge, available to all passengers for a fee regardless of airline or class of service, typically around $30 to $40 USD per entry. United Airlines also operates a United Club for eligible passengers, including Club members, premium cabin travelers, and Star Alliance Gold status holders. These lounges provide comfortable seating, complimentary snacks, beverages, WiFi, and flight information monitors. Shower facilities are available in select lounges, offering a valuable amenity for travelers arriving on early morning flights before business meetings. Access policies and hours can change, so check with your airline or look for updated signage upon arrival at the terminal.

ATMs are readily available in both the pre-security check-in lobby and the post-security departures concourse. They dispense U.S. dollars, the official currency of Guam. Standard international banking fees apply for overseas cards, so notify your bank of travel plans to avoid declined transactions. A currency exchange counter is typically open during peak international flight windows, but relying on an exchange booth is not recommended due to less favorable rates. Instead, withdrawing cash directly from an airport ATM generally provides a better mid-market exchange rate. Most hotels and shops across Guam accept major credit cards, so carrying large amounts of cash is unnecessary for most travelers.

Airlines recommend arriving at least 2 hours before an international departure and 90 minutes before a domestic flight to the U.S. mainland. Guam's traffic is generally predictable, but the single terminal's check-in lines can become congested during the late-night bank of departures to Asia, typically between 10 PM and 2 AM. If you are departing during this peak window, adding an extra 30 minutes is wise. Checking in online before arriving saves significant time. Baggage drop lines move efficiently, but passport verification and security screening still require buffer time. Travelers connecting from regional island flights should pay close attention to minimum connection times provided by their operating airline.

TSA PreCheck is available at GUM for eligible passengers on participating airlines, primarily United Airlines. Approved travelers can use the dedicated expedited screening lane, allowing them to keep shoes, belts, and light jackets on and leave laptops and compliant liquids in their carry-on bags. The availability of the PreCheck lane aligns with peak departure schedules and may not operate 24/7. You must have the TSA PreCheck indicator printed on your boarding pass to access this lane. Guam follows the same Transportation Security Administration protocols as all U.S. airports. If you are not enrolled in PreCheck, simply follow the standard screening procedures, which are clearly explained by security officers.

The post-security concourse features several dining options ranging from quick-service to sit-down venues. Local favorites offer Chamorro-inspired barbecue plates, while familiar global brand outlets serve standard coffee, pastries, and sandwiches. A full-service restaurant provides hot dinners and cold drinks, catering to the late-night long-haul flight crowd. Before security, a small cafe serves passengers seeing off friends and family. Prices are typical of U.S. airport dining, generally ranging from $8 to $18 USD for a meal. Because flight delays can happen, secure-side dining remains open to match departure windows, but choices narrow during the early morning lull between flight banks. Snacks and bottled water are widely available.

Yes, Lotte Duty Free operates an extensive shopping area in the international departures concourse. Travelers can purchase liquor, tobacco, fragrances, cosmetics, luxury chocolates, and Guam-themed souvenirs at tax-advantaged prices. The main store is conveniently laid out, funneling passengers through bright aisles toward their boarding gates. While deals on spirits and cosmetics can be competitive, compare against your home country prices, as some luxury items may not represent a significant saving. You must present a valid international boarding pass to make a purchase. Duty-free liquid purchases are delivered in tamper-evident sealed bags, permissible on connecting flights as long as the seal remains intact per TSA rules.
