Brunei International Airport — Bandar Seri Begawan, Brunei

Brunei International Airport is the principal air gateway to Brunei, serving the capital, Bandar Seri Begawan, on the island of Borneo. The runway system here is modest, just one strip at 73 feet of elevation, yet it carries the country's full load of international connections given Brunei's small size and population. BWN functions as the home base of Royal Brunei Airlines, the national carrier, which links the sultanate to destinations across Asia, Australia, and the Middle East. As Brunei's only major commercial airport, BWN carries outsized importance for a nation whose economy leans heavily on oil and gas exports, since nearly all business and diplomatic travel funnels through this one facility. Despite modest passenger volumes compared with regional giants like Singapore or Kuala Lumpur, the airport's large-airport classification reflects its role as the sole point of international entry for the country, rather than the scale of its infrastructure. Nearly every visitor, trade delegation, and returning resident passes through this one terminal, making BWN synonymous with international travel in Brunei in a way few national airports of larger countries could ever claim.
