Tân Sơn Nhất International Airport is the busiest airport in Vietnam with 32.5 million passengers in 2016 and 38.5 million passengers in 2018.
It serves Ho Chi Minh City as well as the rest of southeastern Vietnam.
As of January 2017, it had a total capacity of only 25 million passengers, which has caused constant congestion and sparked debate for expanding or building a new airport.
The airport's IATA code, SGN, is derived from the city's former name of Saigon.
It was the 25th busiest airport in the world in 2020.
