Structure
Chennai International Airport consists of three terminals: The old terminal at Meenambakkam is used for cargo, while the new passenger terminal complex at Tirusulam is used for passenger operations. The passenger terminal complex consists of the domestic and international terminals interconnected by a link building, which houses administrative offices and a restaurant. Although the complex is one continuous structure, it was built incrementally, with the Kamaraj and Anna terminals being added in 1988 to the pre-existing Meenambakkam terminal.
The first part to be built was the international terminal which had two aerobridges (jetways), followed by the domestic terminal with three aerobridges. After the completion of the domestic terminal, the old terminal at Meenambakkam was used exclusively for cargo. Recently the international terminal was extended further south by adding a new block which includes three aerobridges. At present, the new international block is used for departures while the older building is used for arrivals.
