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.
