Delhi airport’s expanded new Terminal 1 to be opened to passengers from August 17
The older T-1 building of Indira Gandhi International airport still under repair, and only new building will be opened, said DIAL authorities.

The newly expanded world-class Terminal 1 (T-1) of Delhi’s Indira Gandhi International airport will be operational from August 17, announced Delhi International Airport Ltd (DIAL) on Wednesday. This expansion was part of the Phase 3A expansion project, which was inaugurated by Prime Minister Narendra Modi on March 10.
The older T-1 building is still under repair and only the new building will be opened to the public on August 17, said airport officials.
On June 28 a part of the metal canopy over Terminal 1 collapsed due to heavy rainfall, resulting in the death of one man and injury of eight others. After the incident, IndiGo and SpiceJet flight operations, which majorly used T-1, were shifted to Terminals 2 and 3.
In preparation for the terminal’s opening, DIAL has coordinated with airlines IndiGo and SpiceJet to shift their flight operations back to Terminal 1. SpiceJet will be the first to transition, moving 13 flights to the new terminal on August 17. IndiGo will follow suit on September 2, transferring 34 of its flights from Terminals 2 and 3 to Terminal 1.
Regarding the terminal’s launch, Videh Kumar Jaipuriar, CEO of DIAL, said, “The state-of-the-art Terminal 1 will significantly boost our capacity, easing pressure on Terminals 2 and 3. Passengers can expect a smoother travel experience with improved amenities and advanced technology.”
According to officials, the new terminal has features such as the innovative Queue-Buster Mobile Check-in Service, designed to minimize waiting times at check-in counters. Other advanced facilities include the Automated Tray Retrieval System (ATRS), Individual Carrier System (ICS), Common Usage Self Service (CUSS), Aerobridges, and Self Baggage Drop (SBD) kiosks.
Specific entry points for passengers
For passenger convenience, specific entry points have been designated at the new terminal. Passengers flying with SpiceJet will use Entry Gate A on the ground floor, while those flying with IndiGo will enter through Entry Gates 5 and 6 on the first floor, informed airport officials.
All arrivals will occur through a dedicated arrival area on the ground floor. DIAL has installed clear signage throughout the airport and on roadways to guide passengers to the correct departure points, officials added. Additionally, RAXA guards will be on hand to assist and direct passengers to the appropriate areas for IndiGo and SpiceJet flights.
The expansion of Terminal 1 began in 2019 in response to a significant increase in Air Traffic Movements (ATMs) and passenger numbers, which had exceeded earlier projections.
