LHR to DEL: distance bands, operating airlines, connection choices and disruption evidence for this direction of travel.
Examples, not a daily timetable. Confirm the operating airline, airports and stops on your booking.
The great-circle distance between LHR and DEL is approximately 6,731 km, in the over 3,500 km band. This endpoint calculation does not add detours. For a through connection, check the original departure and last ticketed destination before selecting a compensation band.
Air India identifies Delhi–Heathrow as DEL–LHR. Delhi Airport publishes a dedicated winter-fog advisory: low visibility is therefore a concrete seasonal issue to check, not a reason to assume every winter delay is exempt. Ask whether fog, an airport restriction or a later aircraft problem caused your particular arrival delay.
LHR departure puts this direction within UK261's territorial scope on any operating airline. That does not establish payment: arrival delay, cancellation notice, replacement timings and the proven cause still matter. Assess DEL–LHR separately; a return ticket does not make both directions identical.
On the Delhi-origin return, Air India and British Airways produce different UK operator tests; copy the actual operating airline. For a through London–Delhi–domestic India booking, keep the domestic boarding pass and final arrival. A separate Indian domestic booking must be disclosed rather than merged automatically.
Delhi's T1, T2 and T3 are not interchangeable departure points. The official transit guide identifies T3 as handling international services as well as domestic flights, while T1 and T2 serve domestic traffic. Verify the current terminal of the replacement flight rather than following the original ticket automatically.
