Delhi Airports Guide: Terminals, Transport, and Essential Information

Delhi, India’s capital and a major global aviation hub, is primarily served by one massive international airport complex. Unlike cities with multiple separate airports, Delhi consolidates almost all air traffic into a single, sprawling facility with distinct terminals. Understanding which terminal you use is critical, as they function almost like separate airports.

This guide explains the Indira Gandhi International Airport (DEL) complex, including its terminals, IATA codes, and clear, plain-English explanations of how to get to and from the city and navigate between terminals.

Indira Gandhi International Airport (DEL)

Overview: Indira Gandhi International Airport (DEL) is India’s busiest and primary international gateway. Located in Palam, approximately 20 km (12 miles) southwest of New Delhi city centre, it is a massive, modern facility that operates 24/7. It serves as a major hub for Air India, Vistara, and IndiGo, connecting India to the world.

Terminals: DEL operates three main passenger terminals. Crucially, they are not connected airside. You must know your terminal and allow significant time for transfers.

Terminal 1 (T1): The Domestic Terminal. It is further divided into:
- T1D: Handles all domestic flights for IndiGo and SpiceJet.
- T1C: The check-in and arrivals hall that serves both T1D and the adjacent…
- Terminal 1 Annex (T1A): Used by some Akasa Air flights.
Note: A major integrated expansion (T1) is underway to combine these.
Terminal 2 (T2): Currently functions as a flexi terminal used for international arrivals during peak hours, some domestic operations, or as a backup during terminal changes. Always verify if your flight uses T2.
Terminal 3 (T3): The flagship Integrated Terminal. This is where all international flights and full-service domestic carriers (Air India, Vistara, and some IndiGo domestic) operate. It is a vast terminal with separate levels for arrivals and departures.

Key Rule: International flights always use T3 (or occasionally T2). Domestic flights can use T1 or T3. Your airline determines your terminal.

Getting to and from Delhi Airport:

Delhi Airport Metro Express (Orange Line):
The fastest and most reliable way to reach the city centre. Connects both T1 and T3 to key stations in New Delhi (like New Delhi Railway Station) and central Delhi in about 20-25 minutes. Trains run every 10-15 minutes. Highly recommended to avoid road traffic.
Taxi:
Pre-paid taxi counters (official, fixed fare) are available in the arrivals halls of T1 and T3. This is the safest and most hassle-free taxi option. Avoid touts offering “cheap taxis.” Metered taxis are also available but insist on using the meter.
App-Based Cabs (Uber/Ola):
Widely used. Designated pick-up points are at both terminals (follow signs). Can be cheaper than pre-paid taxis but subject to surge pricing and driver cancellations.
Auto-Rickshaw:
Available from T1. Use the pre-paid booth. Suitable for shorter distances or if you have minimal luggage.
Hotel & Private Transfers:
Many hotels offer pick-up services. Private car services can be booked online for a seamless arrival.

Best for: All travellers to Delhi and those connecting across India or internationally. It is the only commercial airport for the National Capital Region (NCR).

Navigating Between Terminals at DEL

This is a critical operation. Since T1 and T3 are not connected airside, transferring between them for connecting flights requires exiting one terminal, travelling across the airport campus, and re-entering the other.

Free Airport Shuttle Bus: Delhi Airport runs a free, 24/7 shuttle bus service between T1 and T3. The journey takes 15-20 minutes without traffic. You must show a valid same-day ticket for the terminal you are travelling to.
By Taxi/Auto: You can take a metered taxi or auto-rickshaw between terminals, but the free shuttle is usually sufficient.
Minimum Connection Time: For self-transfer between terminals (especially International-Domestic on separate tickets), allow at least 4-5 hours to account for immigration, baggage claim, shuttle transfer, check-in, and security.

Essential Information for Delhi Airport (DEL)

Before You Go:

Terminal Verification: Always confirm your terminal with your airline 24-72 hours before your flight, as assignments can change.
Check-in: Arrive 3 hours before international flights and 2 hours before domestic flights. Queues for check-in, security, and immigration (at T3) can be very long.
E-Visa & Documents: Ensure you have the correct visa. The e-Visa line at immigration can be long. Have a printed copy and your return ticket details readily available.

Upon Arrival:

Immigration: Lines can be notoriously slow. Fill out any required forms in advance if not using e-Gates (available for eligible nationals).
SIM Cards: Purchase a local tourist SIM from kiosks in the arrivals baggage hall (Airtel, Jio, Vi). You will need a copy of your passport and visa, and a photo. This is the best place to get one.
Ground Transport: Ignore touts. Walk straight to the official “Pre-Paid Taxi” counter or follow clear signs for the “Metro” or “App-Based Cab” pick-up.

Departing:

Security: Separate security queues for men and women are common. There is often an additional security check at the gate where you may be tagged.
Food & Currency: T3 has extensive dining and shopping options airside. Spend or exchange your leftover Indian Rupees before clearing security, as options are limited airside and exporting large amounts of INR is prohibited.

Safdarjung Airport (Delhi Flying Club)

Overview: A small, historic airfield in South Delhi used only for general aviation, VIP movements, and flying clubs. It handles no commercial passenger flights. Travellers should not confuse this with DEL.

Travel Tips for Delhi

Traffic: Road traffic in Delhi is among the world’s most congested. The Metro Express is almost always faster than road transport during daytime hours. If you must drive, allow at least 60-90 minutes to get to the airport from the city, even for a 20 km journey.

Pollution & Season: Delhi experiences severe air pollution in winter (Oct-Jan). Summers (Apr-Jun) are extremely hot. Plan your wardrobe and activities accordingly.

Scam Awareness: At the airport, be wary of anyone offering “special help,” “hotel deals,” or unofficial taxi services. Use only official counters and pre-booked services.

Bottom line: Delhi’s airport is a complex but world-class facility. Your success hinges on knowing your terminal, using the Airport Metro to avoid traffic, allowing massive amounts of time for everything (immigration, transfers, travel), and using only official transport services upon arrival.
