Guam airport overview
Guam International Airport, officially known as Antonio B. Won Pat International Airport, is situated on the central part of the north coast of Guam. Everything is close by in Guam and the airport is no exception: it’s a mere 5km (3 miles) east of Agana (Hagatna), the capital city of Guam.
Guam International Airport was originally used as a military airport during World War II. In 1992, the first passenger terminal at the airport began to operate as travellers started to realise that Guam had more to offer in terms of beaches, sun and sea. The terminal consists of three levels: arrivals go through the basement level of the terminal, the second floor is mostly admin and the departure gates are located on the third floor.
The airport has served as the perfect base in Micronesia for Continental Airlines. The Antonio B. Won Pat International Guam Airport also serves ANA, China Airlines, Northwest Airlines and Japan Air Lines. Asia Pacific airlines also use the airport as a hub and operate many flights to Guam International. There are regular flights to Antonio B. Won Pat International Guam Airport for holidaymakers travelling from Australia, Japan, South Korea, the Philippines, China and the United States.
Guam is a US overseas territory and the airport took its name from Antonio Borja Won Pat, a citizen of Guam, who was the first delegate to represent Guam in the US House of Representatives. The island is popular with tourists searching for an island getaway.
