Not every flight from London to Sydney takes the same path right now.
2 of 3 routes rated Flowing. Via Singapore is the strongest current option.
Via Singapore — clean airspace routing, with moderate detour impact and reasonable hub reliability.
Best current option for LHR→SYD. LHR–SIN first leg uses Central Asian routing; SIN–SYD second leg is entirely clean. No advisory zone transit on either segment.
LHR–SIN first leg uses the Central Asian corridor — if Eurocontrol flow restrictions are active at departure, this leg is most exposed to delays. Plan extra buffer at Heathrow.
Cleanest airspace on both legs if Gulf avoidance is the priority. LHR–HKG via Central Asia; HKG–SYD clean southerly routing. Longest option but zero Gulf involvement.
High name recognition and strong hub frequency, but the LHR–DXB first leg transits the active Middle East advisory zone. Book with awareness of current conditions.

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.
