Airbus A350 service from Singapore to Kolkata, enhancing the weekly seat capacity. Expansion The construction of the new terminal, as well as runway expansion, marked the end of Phase I of the project. AAI officials have announced that they are prepared to execute Phase 2 of the Kolkata Airport expansion plan. This involves the construction of a new ATC Tower to provide controllers with a better view of the planes at the new terminal. The building will be accompanied by a 4-storey office complex. Initially, a 112-meter tower was proposed, but the height has been revised multiple times and in 2017 it was decreased to 51.4 meter. The under construction tower is expected to be complete by late 2023. New expansion plan The new terminal T2 inaugurated in 2013 is on the verge of reaching its annual capacity of 24 million passengers four years ahead of the initial projections. To tackle this, AAI has planned to upgrade and expand the airport and increase its passenger capacity by 100% to handle up to 40 million passengers annually. The new ₹1,000 crore expansion plan will be carried out in 2 phases. The number of parking bays will be increased to 105 by 2024. Phase 1 Airport officials said as per the first phase of the expansion plan, the old domestic terminal will be demolished and a 7000 sq. m. new building will be constructed in the area. The building will be linked with the existing terminal of the airport with the help of walkalators and would also have walk-in gates on the ground floor. This building will be used only for boarding and de-boarding of passengers. Passengers arriving in the boarding building would take the connecting bridge to the terminal and then leave the airport. This would reduce peak-hour congestion when several flights do not get enough apron space. This would immediately increase the passenger capacity by a few million and would solve the space crunch for the time being. The phase 1 expansion plan has been sanctioned by AAI. Phase 2 A master plan has been made for the construction of a third terminal that will increase the airport's passenger capacity to 45 million. The plan has received the first nod from the aviation ministry. The new terminal T1 will come up north of the current integrated terminal.
