Guam International Airport’s official name is Antonio B. Won Pat International Airport, named in honor of Antonio Borja Won Pat, the first person from Guam to serve as a delegate to the United States House of Representatives.
Its airport code is GUM.

Guam Airport has one main passenger terminal building.

Unlike large hub airports, there are no separate domestic and international terminals.
All flights — including domestic routes to Hawaii and the U.S. mainland, as well as international flights to Japan, Korea, and the Philippines — operate from the same terminal.

The terminal is designed with three levels.
The basement level is for arriving flights and houses the necessary baggage reclaim and customs clearance desks as well as the Airport Police station.

Apron Level is the departures floor with ticketing facilities.

One floor up, the third floor is where the departure gates are located as well as the airport’s immigration facilities.

Once connected to Guam Airport’s Wi-Fi, you can use ride-hailing apps like Stroll to book a ride.
It is generally more economical than taking a regular taxi.

However, one of the most popular options for visitors to Guam is renting a car.

Nissan Rent a Car operates directly at Guam International Airport, with a service counter conveniently located inside the terminal.

They offer on-airport pickup and return services, available 24 hours a day.

As an official manufacturer-operated branch, their vehicles are well maintained and kept in excellent condition.
