Delhi’s Indira Gandhi International Airport is preparing a major overhaul under its Master Plan 2026, aiming to boost capacity, modernize terminals, and potentially introduce a new Terminal 4. With T3 set for a significant expansion and T2’s future under review, the airport is positioning itself for rising passenger demand. Improved inter-terminal connectivity, upgraded infrastructure, and a vision for handling up to 125 million passengers make Delhi a future-ready global aviation hub.
