Daniel K. Inouye International Airport — Honolulu, Oahu, United States

Daniel K. Inouye International Airport, given the code HNL, functions as the main entry point welcoming travelers to Hawaii, handling the bulk of long-haul traffic arriving on Oahu from the US mainland, Asia, and the Pacific. It was renamed in 2017 in honor of the state's longtime United States senator, a decorated World War II veteran who represented Hawaii in Congress for decades. One of its most distinctive features is the Reef Runway, built in the 1970s atop coral fill in shallow coastal waters, an engineering approach that avoided displacing existing neighborhoods. The airport functions as the primary hub for Hawaiian Airlines and serves as the connecting point for inter-island flights reaching Maui, Kauai, and the Big Island. Its open-air terminal design and tropical garden courtyards reflect an architectural style distinct from most major American airports.
