Dong Tac Airport — Tuy Hoa, Vietnam

Dong Tac Airport, also known as Tuy Hoa Airport with code TBB, serves the coastal city of Tuy Hoa in Vietnam's Phu Yen Province. Originally constructed during the Vietnam War era as a military airfield, the site was later converted for civilian use and now supports domestic flights connecting Tuy Hoa to Ho Chi Minh City and Hanoi. The airport serves a region known for its pristine beaches, fishing villages, and the dramatic Da Dia Reef rock formations along Vietnam's central coast. TBB has seen periodic upgrades to accommodate growing tourism interest in this less-developed stretch of coastline compared to more famous destinations like Nha Trang or Da Nang, gradually opening Phu Yen to wider visitor access.
