Chennai International Airport, formerly known as Madras International Airport is located in Tirusulam, 7 km south of Chennai (Madras), India. It is the third busiest airport in the country in terms of international and overall passenger traffic. It is located along Meenambakkam and Tirusulam with passenger entry at Tirusulam and cargo entry at Meenambakkam. The International terminal is named after Former Late Chief Minister of Tamil Nadu, Annadurai. The domestic terminal is named after another former Chief Minister of Tamil Nadu, Kamaraj. It was built on land donated by former governor of Madras Presidency, L. Sriramulu Naidu.Chennai had one of the first airports in India, and was the final destination of Air India's first flight from Bombay (Mumbai) via Belgaum in 1954. The first passenger terminal was built at the northeast side of the airfield, which lies in the suburb of Meenambakkam due to which it was referred to as Meenambakkam Airport. A new terminal complex was subsequently built at Tirusulam, further south near Pallavaram to which, passenger operations were shifted.� 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.
