LHR to SIN: 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 SIN is approximately 10,881 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.
Singapore Airlines advertises London departures from both Heathrow and Gatwick. This page uses LHR, so check that a replacement does not silently move you to LGW. At Changi, a connection onward to Australia may still be part of the same protected London-origin journey; retain the final airport on the ticket.
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 SIN–LHR separately; a return ticket does not make both directions identical.
SIN–LHR on Singapore Airlines and on British Airways requires different carrier-status analysis. A BA marketing number on a Singapore-operated sector is not the same as BA operating it. Changi landing time is not the final arrival when a same-reservation Australian connection is still outstanding.
At Singapore Changi, the distinction between Terminals 1–3, Terminal 4 and Jewel matters during a disrupted connection. A terminal shuttle, an airside connection and a visit to Jewel are different journeys; check which one your replacement itinerary actually requires.
