Delhi Airport's Terminal 2, which began operations in 1986, is expected to be phased out within the next six to seven years as part of a major expansion plan for Terminal 3. The operator, Delhi International Airport Ltd (DIAL), is moving forward with plans for a new Pier E, which will increase the airport's capacity by handling around 1.2 crore passengers annually. Domestic flights currently managed by Terminal 2 will be transferred to the expanded Terminal 3 once Pier E is operational. Discussions with airlines are ongoing to determine the timing of this expansion, which is closely linked to the airlines' fleet expansion and aircraft delivery schedules, impacted by global supply chain issues. The expansion will also necessitate significant infrastructure upgrades, including widening ramps and extending forecourt areas. Additionally, the introduction of an automated air train is planned to enhance passenger movement within the airport complex. The final decisions regarding the future use of the Terminal 2 site remain pending, depending on evolving aviation demand.
