Delhi Indira Gandhi (DEL)
Delhi Indira Gandhi (DEL) at a glance
Indira Gandhi International Airport in Delhi is the busiest airport in India and all of South Asia, handling 77.8 million passengers in 2024, a total that places it among the world's ten busiest and keeps climbing with the fastest-growing major aviation market on Earth. Operated by a GMR Group-led consortium, it became India's first airport with four runways in 2023 and an elevated taxiway to match.
Delhi is the stage for Indian aviation's twin dramas: Air India's Tata-era rebuild, hubbed at the vast Terminal 3 with Singapore Airlines holding 25.1%, and IndiGo's relentless expansion as it takes hundreds of new Airbus jets. The airport's master plan targets capacity beyond 100 million passengers, aiming to keep India's international transfers at home rather than routing them over the Gulf.
