Indira Gandhi International Airport Terminal 3 details

An airport terminal is a building for handling passengers. That big building would be a terminal, by definition. There are airports with no buildings for handling passengers at all… they have no terminals. But they also typically don't have many flights.

Terminal 3 is used by the majority of the members of the Oneworld airline alliance: American Airlines, Cathay Pacific, Finnair, Iberia, Japan Airlines, Qantas, Royal Jordanian, and SriLankan Airlines. British Airways, which mainly uses Terminal 5, also offers some flights from this terminal.
There are no physical airside connections between any of the other terminals. Inter-terminal connections between terminals 1, 2, and 3, and between them and the other terminals, require passengers to exit security, then walk or use a shuttle-bus to get to the other terminal, then re-clear security.
