Indira Gandhi International Airport (IGI), known by its code DEL, is India’s busiest airport and one of Asia’s top 20 by passenger traffic. Located about 16 km from Connaught Place, it serves as the main gateway to over 100 domestic and international destinations.

For many travelers, the challenge isn’t just the flight, it’s understanding which terminal to go to, how to move between them, and how to make the most of the facilities. This guide offers a complete overview of Delhi Airport’s terminals, airlines, connectivity, and traveler tips so your journey feels smoother and less stressful.

Understanding the Terminals at Delhi Airport

Delhi Airport operates through three major terminals, each serving different types of flights. Knowing the right one in advance is essential.

Terminal 1 (T1): Domestic Low-Cost Hub

If you’re flying with IndiGo, SpiceJet, or Akasa Air, you’ll most likely use Terminal 1. Compact in size and recently expanded, T1 is the go-to for budget and regional domestic travel. It has self-check-in kiosks, food courts, prepaid taxi access, and a multi-level car park. The Magenta Metro Line connects directly to this terminal.

Terminal 2 (T2): Transitional Domestic Terminal

At the moment, T2 is closed for renovation, but it is scheduled to reopen in October 2025. Once back in operation, it will handle part of Air India and IndiGo’s domestic flights, designed to make domestic-to-international transfers more efficient. A pedestrian walkway links it directly with Terminal 3.

Update

Starting October 26, 2025, IndiGo Airlines will resume flight operations from Terminal 2 (T2) at Delhi’s Indira Gandhi International Airport (IGI). More details here

Terminal 3 (T3): International & Full-Service Airlines

The largest and most modern terminal, T3 is the home of all international flights along with Air India, Vistara, and some IndiGo domestic routes. It is where you’ll find duty-free shopping, premium lounges, multi-level parking, and the Airport Express Metro line. Travelers heading to or from Connaught Place or New Delhi Railway Station often prefer this terminal for its direct metro connectivity.
