Terminal 2, formerly known as the 'Overseas Terminal,' handles all international connections and some mainland domestic flights. Terminal 1, often referred to as the 'Interisland Terminal,' exclusively services domestic Hawaiian Airlines flights within the state and the U.S. mainland.

At Daniel K. Inouye International Airport (HNL) in Honolulu, the terminals are divided based on the airline and the nature of the flight. Terminal 1 is exclusively dedicated to Hawaiian Airlines. It handles all of the carrier's inter-island flights between the Hawaiian Islands, as well as their domestic mainland U.S. and international departures. Terminal 2, which is the largest terminal at HNL, is the "Overseas Terminal" that services all other major domestic and international airlines, including Delta, United, American, Southwest, and Japan Airlines. Terminal 2 is famous for its open-air garden courtyards that offer a peaceful tropical atmosphere for travelers. There is also a Terminal 3, which is a much smaller facility used primarily by regional commuter airlines like Mokulele Airlines. A free "Wiki Wiki Shuttle" bus and various pedestrian walkways connect the terminals for passengers needing to transfer between carriers.
