Bario Airport — Bario, Malaysia

Up in Sarawak's highlands, Bario Airport carries the code BBN and sits on the island of Borneo in Malaysia. At 3,350 feet, it ranks among the higher-altitude fields in the region, and a single runway forms the entire system connecting the isolated Kelabit Highlands with the rest of Malaysia. Road access to Bario stays limited, so BBN mostly handles short hops on small aircraft rather than anything resembling commercial jet service. The village depends on this airstrip for mail, supplies, and passenger movement to a degree unmatched by most other airfields in Malaysia's network, and its listing in flight databases reflects a modest but genuinely essential piece of highland infrastructure.
