Tan Son Nhat International Airport (SGN/VVTS) is the largest and busiest airport in Vietnam, serving the country's commercial capital, Ho Chi Minh City. It handles both international and domestic traffic, consistently processing over 38 million passengers annually before the COVID-19 pandemic significantly reduced travel volumes. Originally built during the French colonial era and expanded significantly during the Vietnam War when it served as a major U.S. military air base, the airport has since been converted entirely to civilian use. Its infrastructure has struggled to keep pace with rapid passenger growth, leading to chronic congestion. A new terminal (Terminal 3) has been under development to relieve capacity pressures, and a new Long Thanh International Airport is planned northeast of the city to eventually absorb overflow traffic. Vietnam Airlines, Vietjet Air, and Bamboo Airways use Tan Son Nhat as a primary hub.
