Which airlines fly Delhi to London non-stop?
Air India, British Airways and Virgin Atlantic all fly daily from Terminal 3 at Delhi to London Heathrow, several times a day between them. At Heathrow, Air India uses Terminal 2, British Airways mostly Terminal 5 and Virgin Atlantic Terminal 3 — useful to know for pick-ups.
Indian airlines have been routing around Pakistani airspace since 2025, which can add 30–60 minutes to Air India's flights compared with British Airways and Virgin.
What are the best flight timings?
India is 4 hours 30 minutes ahead of the UK in British summer time and 5 hours 30 minutes ahead in winter. Morning and early-afternoon departures from Delhi land the same afternoon or evening, which is easiest on body clocks. Overnight departures land in the early morning — fine for business travellers, harder for families.
Baggage on full-service fares
All three are full-service airlines with meals included. Standard economy usually includes at least one 23 kg bag, but the cheapest "light" fares on some airlines exclude checked baggage. Compare like for like before choosing the lowest fare.
Getting from Heathrow to central London

When to book, and connecting options
Book 6–10 weeks ahead for June–August and Christmas, when students and holidaymakers fill flights. January–March and November are usually cheapest. One-stop flights via Dubai, Doha, Abu Dhabi or Istanbul add 4–7 hours but can save money.
Tips for families and seniors
- Apply for visas early; summer appointment slots fill quickly.
- Request wheelchair assistance at booking — Heathrow walks are long.
- Book a daytime flight with young children, and order vegetarian or Jain meals at least 24 hours ahead.
