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 . </P> <P> Tan Son Nhat International Airport has its origins in the early 1930s, when the French colonial government constructed a small airport with unpaved runways, known as Tân Sơn Nhất Airfield near the village of Tan Son Nhat . By mid-1956, with U.S. aid, a 7,200 - foot (2,190 m) runway had been built and the airfield near Saigon became known as South Vietnam's principal international gateway . During the Vietnam War (or Second Indochina War), Tan Son Nhut Air Base (then using the alternative spelling Tân Sơn Nhứt) was an important facility for both the U.S. Air Force and the Republic of Vietnam Air Force . Between 1968 and 1974, Tan Son Nhut Airport was one of the busiest military airbases in the world . During the last days of South Vietnam, Pan Am schedules from 1973 showed Boeing 747 service was being operated four times a week to San Francisco via Guam and Manila . Continental Airlines operated up to 30 Boeing 707 military charters per week to and from Tan Son Nhut Airport during the 1968--74 period . </P>
