LHR to BOM: 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 BOM is approximately 7,213 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.
Mumbai in this pair is BOM. If an offer mentions another Mumbai-area airport, ask for its code before accepting it. A rebooking through Delhi can introduce a domestic Indian leg, baggage formalities and a different connection, so keep the replacement sequence instead of recording only the London flight.
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 BOM–LHR separately; a return ticket does not make both directions identical.
Air India's and British Airways' Heathrow services illustrate why operating nationality matters on BOM–LHR. The UK departure on the outbound has a different starting point. If you bought a separate domestic flight to reach BOM, retain that booking separately; a missed self-transfer is not automatically a protected through connection.
At Mumbai CSMIA, check BOM and the terminal on each boarding pass. A domestic connection does not mean you can infer the correct terminal from the city or airline name alone. Rebooking may change the building and the required baggage procedure at the same time.
