Cheap flights London to Delhi

October is the cheapest month on this route, and it falls just before the winter rush, so circle it first. Prices are shown for every month from September through August, which means you can weigh a spring trip against a summer one instead of guessing. Midweek departures usually undercut weekend ones, while school breaks and the autumn festival season in India push fares the other way. If your dates are flexible, late autumn and the quieter weeks after the New Year tend to be kinder on the wallet.

Air India and Virgin Atlantic fly this route non-stop, with full-service cabins where a checked bag and a meal are normally part of the fare. Indigo and Air Arabia are the low-cost names here: they connect through their home hubs and charge separately for things like checked bags and seat choice. Qatar Airways, Gulf Air, Oman Air, Finnair, Turkmenistan Airlines and Azerbaijan Airlines all fly one-stop, so the journey stretches but the ticket often costs less. On any connecting fare, check whether your bags are checked through to Delhi or whether you collect and re-check them on the way.

Every flight lands at Indira Gandhi International, the airport serving Delhi, and it sits well outside the city, so leave real time for the transfer. The airport metro line is the quickest way in when the roads are jammed; prepaid taxi counters and app-based cabs are the other options, and the drive to the centre can crawl at peak hours. Immigration and baggage claim happen in the same terminal for international arrivals, so build in a buffer if you are carrying on to a domestic flight. Sort your payment method before you leave the terminal, since local apps often work better than foreign cards, and confirm which terminal your return flight uses.

Country facts: Wikidata

• Check which London airport your fare leaves from, because Heathrow, Gatwick, Stansted, Luton and London City are far apart.
• On a low-cost ticket, add the checked bag and seat you want at the time of booking rather than at the gate.
• If your trip is built from separate tickets, leave a long gap in case the first flight runs late.
• Confirm your visa or entry permission for India and that your passport has enough validity left.
• Book early for October if you want the cheapest month, and compare the weeks on either side of it.
• Check the connection airport and whether your bags are checked through to Delhi.
