The airport is served by the airport metro station of the Chennai Metro and the Tirusulam railway station of the Chennai Suburban Railway system. To cope with the passenger traffic, two new terminals, namely, T2 and one satellite terminal, are under construction to handle 40 million passengers per year. Once completed, it will be India's first airport to have a satellite terminal. The new satellite terminal will be connected through a four way underground walkalator for passenger movement across different terminals. Still, the Tirusulam airport complex is expected to reach saturation by 2035, with a peak capacity of 40 million passengers, and a proposal for a new greenfield airport in Chennai is underway for decades. Once the new airport is commissioned, both the airports will be functional.
