Delhi to London flights — quick facts

Airlines flying Delhi to London non-stop

Air India is the biggest operator, with around 25 weekly non-stops (3–4 daily) on the B777-300ER and the refurbished A350-900, the latter carrying its newest business and premium-economy cabins. British Airways runs about 14 weekly non-stops on the B777-300ER and A350-1000. Virgin Atlantic operates around twice-daily non-stops on the A350-1000 and B787-9. IndiGo launched DEL–LHR in February 2026 with five weekly flights on a Boeing 787 wet-leased from Norse Atlantic, in a dual-class IndiGoStretch-and-economy layout — usually the cheapest economy on the route.

Flight time, distance and routing

Non-stop Delhi to London is about 9h–9h 45m westbound and roughly 8h–8h 40m eastbound, faster with the jet stream. Total distance is around 6,730 km. London is 4h 30m behind India during British Summer Time (late March to late October) and 5h 30m behind during GMT. Most departures are timed morning or late evening, landing in London afternoon or night respectively.

Best time to book and seasonal fares

Peaks are June–August (UK summer, Indian school holidays and family-visit traffic), mid-December (Christmas) and late March/Easter. The cheapest months are usually January to mid-February and October to early November. For non-summer travel book 10–14 weeks ahead; for the June–August peak, 16–20 weeks. One-stop fares via Gulf hubs often beat the non-stop in peak season, at the cost of 4–6 extra hours. Seasonal guidance only — check live fares in the FlightGPT search.

Getting your Delhi-London fare cheaper

IndiGo's new wet-lease service has launched at competitive economy fares, so include it when comparing. Tuesday and Wednesday departures often save 10–20%. A one-stop via Doha (Qatar Airways), Abu Dhabi (Etihad) or Dubai (Emirates) frequently undercuts the non-stop, especially in summer. If you want a strong cabin, search Air India's refurbished A350-900 and Virgin/BA's A350-1000 specifically. No rupee figure is promised here — compare every carrier live in the FlightGPT search.

Airports and terminals (DEL T3, LHR)

Delhi (DEL) — Terminal 3 for all international departures on this route. London Heathrow (LHR) has four passenger terminals: Air India uses Terminal 2 (the Queen's Terminal), British Airways uses Terminal 5, Virgin Atlantic uses Terminal 3, and IndiGo operates from Terminal 4. Check your terminal on the Heathrow site before travel, as transfers between Heathrow terminals take time.

Baggage on Delhi-London flights

Full-service economy on this route is typically 1×23 kg checked + 7 kg cabin, with some Air India fares including 2×23 kg; premium economy and business carry more — see the Air India baggage guide. IndiGo's DEL–LHR IndiGoStretch fare typically includes a generous checked allowance; see the IndiGo baggage guide. Always confirm the exact allowance by fare class on the booking page.

UK visa for Indian passport holders

Indians need a UK Standard Visitor visa, applied online and via VFS Global biometrics in India. The standard six-month visa carries a UK Home Office fee (check the current amount on GOV.UK) plus VFS charges; longer-validity visitor visas exist but still cap each visit at six months. Crucially, even airside transit at Heathrow usually needs a Direct Airside Transit Visa (DATV), as Indians are on the GOV.UK DATV-required list. If you also hold a valid US, Canada, Australia or NZ visa, Transit Without Visa exemptions may apply — verify on GOV.UK.

Connecting alternatives via the Gulf

If the non-stop is pricey, one-stop routings via Doha, Dubai or Abu Dhabi on Qatar Airways, Emirates and Etihad often win on fare and offer excellent cabins, adding only a few hours. These also open more UK arrival options — many Gulf carriers fly onward to Manchester, Birmingham and Edinburgh, which Indian carriers do not serve non-stop. Keep the journey on one ticket for protected connections and through-checked bags.

Travel tips and why visit London

London needs little introduction — the British Museum, the Tower, West End theatre, parks and a vast Indian community and food scene. Summer has the best weather and longest days but the highest fares; spring and autumn balance cost and conditions. For UK cities beyond London, connect via Heathrow on BA, Virgin or Air India, or via a European or Gulf hub. Compare every carrier, including IndiGo's new service, live in the FlightGPT search.
