Honolulu International Airport (IATA: HNL, ICAO: PHNL) is the principal aviation gateway of the City & County of Honolulu and the State of Hawaii and identified as one of the busiest airports in the United States.

Opened in March 1927 as John Rodgers Airport, Honolulu International Airport is the principal hub of Hawaiian Airlines and Aloha Airlines, the two largest Hawaii-based airlines. Both airlines offer flights between the various airports of the Hawaiian Islands and also serve the continental United States. Honolulu International Airport is host to major United States and international flagship commercial carriers with direct routes to American, Asian, and Pacific Rim destinations.

Due to its proximity to the center of the Pacific Ocean, Honolulu has historically been a stop for many transpacific flights to and from North America. With the advent of ultra-long range aircraft, however, many flights are now able to overfly Honolulu - the notable exception being flights between Australia and Canada. As such, the airport has seen a notable decrease in international passenger traffic over the years. Now that virtually all airline service to Honolulu is based on demand, there are far fewer flights to Australia, the South Pacific or southeast Asia today than 15 or 20 years ago. Almost all flights now go to Japan or the United States. However, Honolulu has continued to see major growth in the domestic market as major airlines have added frequencies and even non-stop links to smaller hubs such as Phoenix, Denver and Cincinnati.
