The Daniel K. Inouye International Airport was built in 1927 and was Hawaii’s first complete airfield. The airport has a large runway built on reclaimed land called the coral runway. This runway was designated as an emergency landing strip for the Space Shuttle. On any given day, there are around 190,000 visitors to Oahu, which is up from around 8,000 during the COVID lockdowns and still down from the 200,000 visitors in 2019. This makes the Honolulu International Airport a very busy place. The Honolulu International Airport shares some facilities with the adjacent Hickam Air-force Base, so it is not uncommon to see military aircraft coming and going as your plane taxis out to the runway. The body of water next to the airport is called Keehi Lagoon. It was once used as a takeoff and landing area for seaplanes and flying boats. The Daniel K. Inouye International Airport has three main terminals. One for inter-island flights, one for international and domestic flights to the US Mainland, and the final is for small planes. There are also handling facilities for private planes and helicopters. Many helicopter tours operate from this area.
