Honolulu International Airport (HNL) serves Honolulu, United States, and sits at an elevation of just 13 feet above sea level, reflecting its location on the coast of Oahu. The airport lies approximately 3.5 miles from the city center, making it a short and convenient distance from downtown Honolulu.

Given its position in the Pacific, Honolulu International Airport functions as a key gateway connecting the Hawaiian Islands to destinations across North America and beyond, while also supporting inter-island travel throughout the state. The airport's traffic reflects this dual role, combining domestic connections within the islands with longer-haul flights reaching across the Pacific Ocean toward the North American mainland and other international points. Its low elevation and coastal setting mean that flights arriving and departing typically operate over open water for significant portions of their approach and departure paths, a characteristic feature of island airports in this region. Travelers using Honolulu International Airport can expect a mix of short regional hops and extended overwater routes, underscoring the airport's importance as both a local hub for the Hawaiian archipelago and a broader link between the Pacific and other continents.
