Hilo International Airport — Hilo, United States

ITO is Hilo International Airport, serving Hilo on the Big Island of Hawaii. Located on the wetter, eastern side of the island near Kilauea and Hawaii Volcanoes National Park, ITO provides an alternative entry point to the Big Island distinct from the busier Kona International Airport on the drier west coast. The airport primarily handles inter-island flights within Hawaii along with some flights to the U.S. mainland, serving residents, volcano researchers, and tourists visiting the island's lush rainforest, waterfalls, and active volcanic landscapes. Hilo's economy has historically centered on agriculture, particularly macadamia nuts and tropical flowers, and ITO supports the transport needs of this quieter, less tourist-saturated side of the Big Island.
