The new satellite terminal will be connected through a four way underground walkalator for passenger movement across different terminals. Still the airport will reach saturation by 2022 with a peak capacity of 40 million passengers and a proposal for new airport in chennai is underway for decades. Once the new airport is commissioned, both the airports will be functional until all operations are moved to the new airport.

It was the first airport in India to have international and domestic terminals located adjacent to each other. This airport serves as the regional headquarters of the Airports Authority of India for South India comprising the states of Tamil Nadu, Andhra Pradesh, Telangana, Karnataka, and Kerala and the union territories of Puducherry and Lakshadweep.
