Guam Airport Information

Guam’s primary airport is Antonio B. Won Pat International Airport, commonly called Guam Airport. The airport’s namesake is the first delegate from Guam to the U.S. House of Representatives, and it is operated by the Guam International Airport Authority which took over the facility in 1976. Since then, two new terminal buildings have been built and the airport can handle 2.5 million passengers. Guam, a  U.S. territory, is a tropical paradise with great infrastructure and plenty to see and do- so the airport needs to be able to process its many visitors! 
Guam’s current terminal was completed in 1998 and was built to grow as air traffic to Guam increases. It has three levels, with arrivals, baggage claim and airport police on the first level, ticketing counters on the second (apron) level, and departure gates and immigration facilities on the third. There are 21 gates, and everything one could need from an airport in terms of eating, drinking and shopping- with eateries scattered all over the terminal both before and after security and duty free shops for departing and arriving passengers. There is a United Airlines lounge for their VIP passengers and United Club members on the departures concourse, and a Sagan Bista Lounge which is operated by Delta Air Lines and Lufthansa and open to their VIP passengers and frequent fliers.
There are a long list of airlines flying from Guam Airport, and an even longer list of possible destinations. Most flights are to various Asian airports, with some to Australia, Russia and the United States. China Airlines, Japan Airlines, Jeju Air, Jin Air and Korean Air operate frequent flights to China, Japan and Korea, along with United which has a large presence in the airport and a huge number of destinations including Hong Kong, Honolulu, Cairns, Manila and many more.
Security at the airport is administered by the U.S. Transportation Security Administration. Anything that could potentially be considered a weapon is strictly forbidden from all carry-on luggage, and there are restrictions on liquids and gels, which must be less than 3.4 ounces each and collectively placed in a clear, quart-sized ziploc bag. The usual suspects are restricted by customs rules- fresh fruit and vegetables, plants, animals, drugs and weapons. Guam is a territory of the United States, so U.S citizens do not require a passport unless passing through any non-U.S. ports, although it is advised. All other arrivals will require a passport and a U.S. visa.
The airport is located quite centrally on the island of Guam, not far from the capital, Hagåtña. It is surrounded by suburbia so there are plenty of shops, restaurants and hotels within a very short drive of the terminal. The heart of Hagåtña is only 6 kilometres from the airport terminal, and dotted around the rest of the island are beaches, villages and picturesque rural areas in the southern end. The climate is generally warm and humid.
