About
Indira Gandhi International Airport (DEL) is India's largest and busiest airport, handling ~70 million passengers annually. Operated by Delhi International Airport Limited (DIAL), a GMR Infrastructure-led consortium under a 30-year operate-maintain-develop concession from the Airports Authority of India.
The airport's centrepiece is Terminal 3 (T3), opened in July 2010 ahead of the Commonwealth Games. T3 was Asia's largest airport terminal at opening with 5.4 million square feet of floor area, 78 immigration counters, 168 check-in counters, 90 air-bridges, and capacity for 34 million passengers annually. Construction was executed by L&T at ₹12,700 crore — completed in 37 months from groundbreaking, an exceptionally fast schedule for a terminal of this scale.
The airport has three runways (28/10, 29/11, 27/09) — making it one of the few Indian airports with parallel triple-runway operations — plus an Air Force separate-use runway (V-runway). T3 is the international + domestic-Air-India terminal; T1 (renovated 2024) handles low-cost domestic; T2 is reserved for surge operations.
IGI is a 5-star Skytrax airport (since 2015) and ranks among the world's top 15 busiest airports by passenger traffic. A 4th runway and Terminal 4 are under planning to handle projected 2030 throughput of 130 million passengers.
