Indira Gandhi International (IGI) Airport (IATA: DEL, ICAO: VIDP), located in Delhi, is one of India's main domestic and international gateways. The airport has been named after former prime minister Indira Gandhi, the daughter of Jawaharlal Nehru. It is the second busiest airport in South Asia.

Earlier known as Palam airport, it was renamed IGI airport with the inauguration of a new international building (Terminal 2) on 2 May 1986. The older Palam airport (Terminal 1) is exclusively used for domestic operations. A new Terminal 3 building should be complete by 2010.

There is a free transfer shuttle between the Indira Gandhi International terminals.
