Dong Tac Airport, designated by IATA code TBB and ICAO code VVTH, serves the city of Tuy Hoa in Phu Yen Province, central Vietnam. It handles domestic passenger traffic connecting this coastal region to major Vietnamese cities such as Hanoi and Ho Chi Minh City. The airport occupies a site near the coast and operates as a relatively small regional facility. It supports both civil aviation and has historical roots as a military airfield used during the Vietnam War era. Passenger volumes remain modest compared to major Vietnamese hubs, reflecting the regional nature of Tuy Hoa's economy and tourism base, though the area's beaches and natural attractions draw increasing visitor interest.
