Bintulu Airport — Bintulu, Malaysia

Bintulu Airport serves Bintulu, a coastal city in Sarawak, Malaysia, on the island of Borneo, home to a major liquefied natural gas export industry. The airport, coded BTU, is set at 74 feet in elevation, and traffic moves across a single runway shared by cargo flights and regular passenger service tied closely to the energy sector. Domestic routes from BTU connect Bintulu to Kuching, Kota Kinabalu, and Kuala Lumpur, serving both local residents and workers employed by the LNG plants and related industries based in the area. Given Bintulu's distance from Sarawak's other major cities, the airport remains a vital piece of infrastructure for the wider region's economy.
