Tân Sơn Nhất International Airport is an international airport serving Ho Chi Minh City, the largest city of Vietnam. It serves Tan Binh District, where the airport is located in the Ho Chi Minh City metropolitan area, as well as the rest of southeastern Vietnam. It is the busiest and largest 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 second-busiest in Southeast Asia. As of April 2024, it has a total capacity of only around 30 million passengers, which has caused constant and increasing traffic and congestion, hence it has sparked debates for expanding or building a new airport, of which the plan of the new airport as an alternative is under construction since 2021, and will be completed by 2025.
