London to Delhi flights

When fares to Delhi are lowest

Fares to Delhi are usually lowest outside Diwali, Christmas and New Year, Holi in March, and the UK school summer holidays in July and August. Book well ahead for festival travel and use the live fare calendar on this page, which shows this month's lowest fares, to compare your dates before you commit.

School terms and quieter weeks give you more room to choose. If your trip is flexible, shift your dates by a few days either side of a peak and compare what the calendar shows.

1. Open the live fare calendar on this page and note this month's lowest fares.
2. Enter your travel dates and check the days either side.
3. Set a price alert for the route so you get an email when fares drop.
4. Book once the fare sits under the usual price for your dates.

Direct flights and airlines on the route

Nonstop flights from London to Delhi are operated by Air India and British Airways, landing at Indira Gandhi International Airport (DEL). Other options we have seen involve stops, including Pegasus and AJet, or self-transfer routes that pair easyJet and Ryanair with a separate long haul ticket.

Nonstop is the simplest choice if you are travelling to see family, for a wedding or for work, because you land at DEL without changing planes. Check the operating airline on your booking before you pay.

Self-transfer routes can look appealing, but they are separate tickets. If the first flight is delayed, the second airline has no duty to rebook you, so allow a long connection and travel with hand luggage if you can. Pegasus and AJet routes with stops work the same way: confirm the connection is on one ticket before booking.

Remember the time difference when you pick flights. India is 5 hours 30 minutes ahead of the UK in winter and 4 hours 30 minutes ahead in British Summer Time, so plan pickups on Delhi local time.

Festival and holiday peaks to plan around

Diwali falls on 8 November 2026 and about 29 October 2027, and these weeks are among the busiest for London to Delhi travel. Christmas and New Year, Holi in March, and the UK school summer holidays in July and August also push fares up, so book early for weddings and family events in these periods.

Diwali dates move each year, so check the exact day before you fix your trip. Fares for the days around the festival tend to firm up months ahead.

Christmas and New Year catch people visiting family, and Holi in March brings another spike. The UK school summer holidays in July and August are the longest busy stretch, so families should plan furthest ahead.

Arriving in Delhi: phone, data and entry

India's main mobile networks are Jio, Airtel and Vodafone Idea, with coverage up to 5G. Sort out data before you fly so you can call family on landing and use maps at Indira Gandhi International Airport (DEL). Check the official entry rules for your passport before you travel.

A travel eSIM and a mobile top up bought before departure mean you land connected.

Entry requirements depend on your passport, so read the official rules for your nationality well before you fly. Do not rely on second hand advice.

How to get a price alert for your dates

Set a price alert on this page and we check fares every day and email when they fall well under the usual price for your dates or under your own target. That suits people booking around Diwali, Christmas or a wedding, when fares move quickly.

Add your route, your dates and your target, and let the alert do the watching. Use it alongside the live fare calendar on this page, which shows this month's lowest fares, so you know what a good fare looks like before you set your target.
