Indira Gandhi International Airport (IGI) in Delhi is India's busiest airport. There are plans to eventually have two international terminals at this airport to manage the crowd. IndiGo, India's largest domestic airline, has requested that Delhi International Airport Limited construct some infrastructure to handle the foreign flow of customers. It has requested that facilities for handling foreign crowds be developed for the impending expanded Terminal 1. Presently all international flights are managed by Terminal 3. According to a source, the expansion strategy was to make it an all-domestic terminal. The construction of the same slowed down owing to COVID-19 in 2020 and 2021. However, the rebound in travel following the pandemic was entirely unforeseen and has made the authorities consider the new plan.
Given the rise in traffic, the expansion of T1 will go on as per the original plan. After the completion, the clearance for international traffic at T1 will be taken by multiple government agencies. Now, the expansion and renovation of Terminal 1 are anticipated to be completed by September 2023. IndiGo Airlines currently operates through all three terminals: T1, T2, and T3. It has insisted on running all of its flights from one. This is to improve operational efficiency and passenger comfort. Given the current settings, travelers find it hard to travel between all of the terminals as there aren't any automated carriers (like air trains). There have been instances where travelers have arrived at the wrong terminal and had to hurry to their correct one. Once the updated strategy takes place, the issue will be solved.
