In order to cope with the passenger traffic two new terminals namely T5 and T6 (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 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.
