To fly to Sabah, Borneo you need to fly to one of three airports – Kota Kinabalu airport (BKI) the main gateway to Sabah, Sandakan airport (SDK) on the east coast and Tawau airport (TWU) on the south coast. Which airport you fly in to/out of depends upon your itinerary and your flight route to Sabah. There are currently direct flights to an airport in Sabah from a range of airports in South East Asia with most direct routes being via Kuala Lumpur, Singapore or Hong Kong. More recently you can fly direct to Kota Kinabalu (BKI) from South Korea, certain cities in China, Taiwan, Japan and the Philippines. For other parts of Borneo, you can fly to Sarawak’s Kuching airport and Brunei’s Bandar Seri Begawan airport.
