Bangkok Airways is a Thai airline that flies passengers to destinations across Thailand and Southeast Asia. It is best known for operating several smaller regional airports in Thailand, including the ones serving Koh Samui, Sukhothai, and Trat — tourist islands and historic towns that most major airlines do not serve. This makes Bangkok Airways unusual because it both runs the airline and owns the airports it flies into.

The company earns money by selling plane tickets, charging airport fees, and offering ground handling and other airport services to other airlines. It operates mainly within Thailand and on short regional routes to neighboring countries like Cambodia, Myanmar, and the Maldives. Owning its own airports gives Bangkok Airways a strong competitive advantage because rivals cannot easily compete on those routes. The main growth driver is continued recovery in Thai tourism, but the business faces real risk from rising fuel costs and competition from low-cost carriers expanding across Southeast Asia.
