Kona International is the only remaining major airport in the Hawaiian Islands where a mobile ramp is used to plane and deplane passengers. Kona International sees daily Airbus and Boeing jetliner service including 717, 737, 757, 767, A321, A330 and 777 aircraft, as well as smaller inter-island aircraft, and general private aviation. The airport terminal is a rambling, open-air set of structures. Long after other airports in Hawaii converted their terminals to multi-story buildings with automated jetway systems, Hawaiian Airlines could still utilize their DC-9 fleet's tailcone exits at Kailua-Kona.
