"Tan Son Nhat International Airport (Vietnamese: Sân bay Quốc tế Tân Sơn Nhất) is Vietnam's largest international airport in terms of area (1,977 acres compared with 1,606 acres of Hanoi's Noi Bai International Airport and Da Nang's Da Nang International Airport). It has a handling capacity of 15-17 million passengers per year, compared with the capacity of Hanoi - Noi Bai airport of 8 million passengers and Da Nang's 2 million passengers. It is also the largest airport of Vietnam in terms of passengers handled (with an estimated number of over 12.5 million passengers per year in 2009, accounting for more than half of Vietnam's air passenger traffic), serving Ho Chi Minh City as well as Dong Nam Bo in southern Vietnam. Its IATA code SGN was derived from the city's former name of Saigon."
For an airport of such a commanding size, the urinals serving the facility are exceedingly small.
