Changing terminals at Delhi Airport can feel confusing, especially when you have a connecting flight departing from a different terminal. But the process is fairly straightforward once you know which transport option to use.

Delhi's Indira Gandhi International Airport (IGI Airport) has three terminals—T1, T2 and T3—and passengers have several ways to travel between them.

The free shuttle bus is the easiest option

For most passengers, the free inter-terminal shuttle bus is the most convenient way to travel between terminals.

The shuttle service operates around the clock and connects the airport's terminals at regular intervals.

If you need to travel from T1 to T2 or T3, head towards Lane 1 in the arrivals area and follow the signs for the inter-terminal shuttle.

Passengers may need to show their boarding pass and obtain a transit bus coupon from the designated kiosk before boarding.

Travelling between T2 and T3

T2 and T3 are located relatively close to each other, making this transfer easier than travelling from T1.

The terminals are approximately 500 metres apart. Passengers who are comfortable walking and have manageable luggage may be able to make the journey on foot.

If you're carrying heavy bags or travelling with elderly passengers, using the shuttle bus may be more convenient. Buggy services may also be available on request.

Passengers travelling from T3 towards T2 can also use the connecting tunnel near Pillar 18.

What happens if you have connecting flights?

Changing terminals becomes slightly more complicated when your connecting flights are on different airlines or involve checked baggage.

For some domestic connections, you may need to:

1. Collect your checked baggage.

2. Exit the terminal.

3. Travel to the next terminal.

4. Check in again.

5. Drop off your baggage.

6. Clear security once again.

The exact process depends on your airlines, tickets and whether your baggage is checked through to the final destination.

International connections may require extra time

If your connection involves an international flight, you may have to complete additional formalities such as immigration, customs and security checks.

This is why passengers with international connections should allow plenty of time between flights rather than relying on the minimum connection time.

Keep these things in mind before changing terminals

Before leaving for the airport, check the terminal mentioned on your latest flight information or boarding pass.

Also remember to:

• Keep your boarding pass easily accessible.

• Check whether your airline operates from T1, T2 or T3.

• Allow sufficient time for the terminal transfer.

• Consider your baggage when deciding whether to walk or take the shuttle.

• Follow airport signs rather than relying solely on directions from other passengers.

• Confirm your connection and check-in requirements with the airline if you have separate tickets.

The bottom line

Changing terminals at Delhi Airport doesn't have to be stressful. The free inter-terminal shuttle is generally the most convenient option, while T2 and T3 are close enough to make the transfer relatively easy.

The most important thing is to check your terminal in advance and leave enough time for the transfer, check-in, baggage and security procedures. A little preparation can make your airport connection much smoother.
