Not every flight from London to Singapore takes the same path right now.
3 routes assessed for this corridor. Via Istanbul scores highest.
Via Istanbul — lower exposure than Gulf-connected options, with minimal detour impact and reasonable hub reliability.
Best option for LHR→SIN. Avoids the Middle East advisory zone on both legs. Turkish Airlines and Singapore Airlines both serve this pairing via IST, giving strong combined frequency.
Route passes near an advisory zone (not through it)
IST–SIN second leg routes over Iran/Pakistan. If Iranian FIR restrictions tighten, this leg could be rerouted, adding up to 40 minutes.
Gulf-free routing via Cathay's Hong Kong hub. Longer total journey but cleanest airspace profile of the three options.
Reliable option with high frequency, but the LHR–DXB leg crosses the active Middle East advisory zone.
Active disruptions
FlightDetour evaluates route options using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on publicly available EASA and national authority advisories.
Coverage focuses on major long-haul corridors. Some routing patterns — including certain China-side connections via mainland Chinese hubs — are not yet included. If you expect an option here and don't see it, that's a coverage gap, not an assessment.
Scores compare corridor quality; they do not predict airline operations or safety outcomes. Verify with your airline and government travel advisories before booking.
