Tan Son Nhat International Airport (IATA: SGN, ICAO: VVTS) is an international airport serving Ho Chi Minh City, the most populous city in Vietnam. It is located in the former Tân Bình district within the Ho Chi Minh City metropolitan area.
It is the busiest airport in Vietnam, with 32.5 million passengers in 2016, 38.5 million passengers in 2018, and about 41 million passengers in 2023. As of December 2023, it is the 50th-busiest airport in the world, and the fourth-busiest in Southeast Asia. As of April 2025, it has a total capacity of approximately 50 million passengers following the opening of Terminal 3. Previous capacity limits of approximately 30 million passengers had caused constant and increasing traffic and congestion, leading to the construction of another airport in Ho Chi Minh City as an alternative, scheduled to be completed by the first half of 2026.
