Named after Indira Gandhi, a former Prime Minister of India, Indira Gandhi International Airport is the busiest airport in the country in terms of passenger traffic since 2009. With the commencement of operations at Terminal 3 in 2010, it became India’s and South Asia’s largest aviation hub. In 2014, the airport handled a total of more than 39 million passengers. The airport serves as hub for Air India, AirAsia India, GoAir, IndiGo, Jet Airways, SpiceJet and Vistara.
Safdarjung Airport was built in 1930 and was the main airport for Delhi until 1962. Due to increasing passenger traffic at Safdarjung, civilian operations were moved to Palam Airport (later renamed to IGIA) in 1962.
