Today, the airport occupies 4,520 acres and has four active runways- including the impressive Reef Runway, which measures 12,000 feet and is the first major runway in the world to be built entirely offshore. It is served by 27 domestic and international carriers, four commuter airlines, and three inter-island airlines.

Yes, Daniel K. Inouye International Airport (HNL) is a very large and busy hub, serving as the principal gateway for the Hawaiian Islands. It covers over 4,500 acres, which is larger than some small cities, and features four active runways, including the famous "Reef Runway" built entirely on reclaimed land in the ocean. The airport is divided into three terminals: Terminal 1 (primarily Hawaiian Airlines), Terminal 2 (international and major US carriers), and Terminal 3 (small commuter airlines). Navigating it can be a challenge due to its "open-air" design and long walking distances; however, the Wiki Wiki Shuttle (a fleet of buses) helps transport passengers between concourses. In 2026, the airport has fully integrated the "Mauka Concourse" expansion, which added modern gates and improved TSA efficiency. While it is not as massive as Atlanta or Denver, its unique layout and high volume of wide-body aircraft for transpacific flights give it the feel of a major global megahub, often requiring at least 20-30 minutes to transit from security to the furthest gates.
