CAI to LHR: 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 CAI and LHR is approximately 3,533 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.
Cairo International is CAI, while Sphinx International is SPX. They are different airports even when a booking search groups them under Cairo. A replacement to SPX should specify the transfer to the original or agreed destination, particularly if an onward domestic flight still leaves from CAI.
CAI–LHR begins outside the EU/UK. A standalone UK arrival generally needs a UK or EU operating carrier for UK261; a non-UK/non-EU operator is not covered by destination alone. Show any earlier same-reservation departure before applying this standalone-sector rule.
British Airways is a UK-operator example, but do not assume every Cairo–London ticket is operated by BA. The CAI-origin return can turn on that distinction, while a departure from Heathrow starts within UK scope on any airline. A through itinerary onward into Egypt needs all sectors, not only the London leg.
Heathrow's crucial distinction is between a protected airside connection and two flights you booked separately. The terminal-transfer route, baggage collection and border formalities can differ even when both tickets say LHR.
