Brunei International Airport (BWN/WBSB) is the only international airport in the Sultanate of Brunei, serving the capital Bandar Seri Begawan. It functions as the primary hub for Royal Brunei Airlines and handles the majority of the country's air traffic, both commercial and general aviation. The airport features a modern terminal building that was significantly upgraded and expanded in the 1990s to accommodate growing passenger numbers. Its strategic location on Borneo island connects Brunei to destinations across Asia, the Middle East, and beyond. Despite Brunei's small population and land area, the airport maintains international standards of infrastructure and handles a mix of regional and long-haul flights. Passenger volumes are modest relative to regional peers, reflecting the country's size.
