Indira Gandhi International Airport, also known as IGI Airport or Delhi Airport, is one of the busiest and most important airports in India. Located in Palam, New Delhi, the airport covers more than 5,100 acres and handles millions of passengers every year. It is named after former Prime Minister Indira Gandhi and is operated by Delhi International Airport Limited (DIAL), a consortium led by the GMR Group along with the Airports Authority of India, Fraport Germany, and Eraman Malaysia. Over the years, Delhi Airport has expanded its infrastructure, upgraded its terminals, and added new technologies to offer a smoother travel experience.

Today, IGI Airport is known for its world-class terminals, advanced safety systems, improved baggage handling, growing airline network, and excellent connectivity to all parts of Delhi NCR.

Terminals at Indira Gandhi International Airport

Delhi Airport operates through three main terminals – Terminal 1, Terminal 2, and Terminal 3. Each terminal is designed to manage different air traffic and provide specific facilities to passengers.

Terminal 1: Dedicated to Domestic Low-Cost Carriers

Terminal 1 caters mainly to domestic, low-cost airlines. After major expansion work, the terminal became operational on 15 April 2025. Its total area has increased from 55,740 sq mt to 206,950 sq mt. The terminal now provides both arrival and departure services under one building.

Key upgrades at Terminal 1 include the DigiYatra facial recognition system, more than 100 common-use kiosks for fast check-ins, and a baggage handling capacity of 6,000 bags per hour.

Terminal 2: Reopened in October 2025 After Renovation

Terminal 2 was closed in April 2025 for renovation and reopened on 25 October 2025. The upgraded terminal now handles up to 15 million passengers annually. The new design includes skylight ceilings, improved fire safety systems, better flooring, modern interiors, updated boarding bridges, and self-baggage drop counters.

The reopening of T2 has reduced the load on Terminal 3 and improved the flow of domestic flights.

Terminal 3: Main Terminal for Domestic and International Flights

Terminal 3 (T3) is the largest and most advanced terminal at Delhi Airport. Spread across 20 acres, it manages most international flights and some domestic operations. With around 168 check-in counters, almost 100 immigration counters, automated baggage handling, and a multi-level parking system, T3 provides a smooth travel experience for passengers.

It also houses several lounges, duty-free shops, restaurants, and passenger service centers.

Expansion of Terminal 3

Delhi Airport is currently working on expanding Terminal 3 to increase international handling capacity. One domestic pier (Pier C) is being converted into an international pier, which is expected to raise international capacity from 20 million to 32 million travellers annually. Due to this upgrade, Air India and Air India Express have shifted some domestic flights to Terminal 1 and Terminal 2.

A future plan includes building a new international pier, Pier E, expected to be completed by 2028.

Future Terminals: T4, T5, and T6

The airport authorities have proposed three new terminals – Terminal 4, Terminal 5, and Terminal 6. Once completed, most international flights will be shifted to these new terminals. Terminal 3 will then handle domestic flights only. This expansion aims to support Delhi’s rise as a major global aviation hub.
