Delhi Airport's Terminal 1 (T1) is set to resume operations on August 17 after being closed since June 28 due to a roof collapse caused by heavy rains, resulting in one death and several injuries. This reopening is part of the Phase 3A expansion project by Delhi International Airport Limited (DIAL), led by the GMR Group, and was inaugurated by Prime Minister Narendra Modi in March. The new terminal aims to alleviate congestion at Terminals 2 and 3, enhancing overall airport capacity and passenger experience with advanced amenities and technology. Initially, SpiceJet will move 13 flights to T1 on August 17, followed by IndiGo shifting 34 flights on September 2. Despite these changes, T1 will operate at 25% of its pre-collapse capacity. Passengers are advised to check their terminal information and note the specific entry gates for SpiceJet (Gate A) and IndiGo (Gates 5 and 6).
