According to the most recent information, the Indira Gandhi International Airport (IGI) in Delhi may soon be expanded to include two international terminals.
At this time, the only facility that is able to handle foreign flights is Terminal 3 at the IGI airport. On the other hand, extensive improvements of Terminal 1 (T1) at IGI are currently underway and are scheduled to be completed by September 2023 at the latest. The Terminal 1 of the Delhi Airport can begin operating international flights once renovations are complete.
According to one of our sources, “The expansion was intended to be a domestic terminal only.” During the years 2020 and 2021, the pace of work on T1 was slowed down because to Covid. After then, the recovery in airline travel has been far stronger than anyone had imagined it would be. As a result, the construction on T1 will be finished according to the original plan in order to avoid any delays caused by the increase in traffic, and after that, clearance will be sought from the many government entities that are concerned in order to have facilities for international traffic at T1″.
It has also been stated that it is just a matter of time before Terminal 1 begins handling both domestic and international flights, as soon as it receives all of the necessary clearance from the government. It is believed that in the not too distant future, Tata Group airlines (Air India-Vistara and AI Express-AirAsia India integrated) and foreign carriers will use Terminal 3, while T1 will be responsible for handling low-cost airlines such as IndiGo. On the other side, T2 is going to be responsible for handling all of the domestic flights.
Because of the existing circumstances, it is becoming increasingly difficult for people to move about the airport from one terminal to another using automated movers (also known as air trains). There have been occasions when passengers have arrived at the incorrect terminal and been forced to make a mad dash to the terminal that was intended for them.
