Indira Gandhi International Airport is about 14km southwest of the centre. International and domestic flights use the gleaming new Terminal 3. Ageing Terminal 1 is reserved for low-cost carriers. Free shuttle buses (present your boarding pass and onward ticket) run between the two terminals every 20 minutes, but can take an hour or more. Leave at least three hours between transfers to be safe.
The arrivals hall at Terminal 3 has 24-hour forex, ATMs, prepaid taxi and car-hire counters, tourist information, bookshops, cafes and a Premium Lounge with short-stay rooms.
You’ll need to show your boarding pass to enter the terminal. At check-in, be sure to collect tags for all your carry-on bags and ensure these are stamped as you go through security.
Delhi’s airport can be prone to thick fog in December and January (often disrupting airline schedules) – it’s wise to allow a day between connecting flights during this period.
