The story of today’s Kona airport begins with the rapid growth of West Hawaiʻi in the 1960s. The former Kona Airport near Kailua could no longer meet long-term aviation needs, so the State of Hawaii planned a new facility at Keāhole. Construction began in 1969 on a large lava-field site north of Kailua-Kona, with crews creating a new runway, taxiway, aircraft apron, terminal buildings, roads, parking, support facilities, and an air traffic control tower.
Keahole Airport was dedicated on July 1, 1970, and operations shifted from the old Kona Airport without interrupting scheduled service. The original airport featured a 6,500-foot runway and a cluster of high-beam, Polynesian-inspired terminal buildings. That village-like architectural concept became one of the airport’s defining characteristics and helped establish the open-air atmosphere visitors still associate with KOA today.
A major turning point came in 1994, when the runway was extended from 6,500 feet to 11,000 feet. The longer runway made it possible for fully loaded wide-body aircraft to operate direct services between Kona and distant mainland gateways. Scheduled transpacific operations expanded the airport’s role from a primarily interisland facility into a major western gateway for Hawaiʻi Island.
International capability developed further in the 1990s with federal inspection facilities supporting direct flights from Japan. In later years, passenger growth led to terminal modernization, including improvements to security screening, holding rooms, concessions, restrooms, and circulation between the north and south portions of the terminal complex. The airport was renamed in honor of Ellison Onizuka, the Hawaiʻi-born astronaut and U.S. Air Force officer who died aboard Space Shuttle Challenger in 1986.
Today KOA continues to evolve through modernization and long-range planning while preserving an airport experience strongly shaped by its lava-field setting and low-rise, open-air design. It remains essential to tourism, local residents, cargo movement, business travel, and the transportation network connecting Hawaiʻi Island with Honolulu, the mainland United States, and international markets.
