Not every flight from London to Seoul takes the same path right now.
3 routes assessed for this corridor. Via Hong Kong scores highest.
Via Hong Kong scores highest on this corridor — lower exposure than Gulf-connected options, with moderate detour impact.
Best-rated option for LHR→ICN. HKG→ICN second leg is only 3.5 hours via clean Korean airspace. No Gulf exposure on either leg.
Limited alternative paths if the main corridor is disrupted
LHR→HKG depends on the Central Asian corridor. Check Eurocontrol ATFM status day-of. HKG→ICN is clean and high-frequency.
Hub break at Istanbul before the long Central Asian corridor leg to Seoul. Lower advisory exposure than Gulf options.
Most direct routing when the Central Asian corridor is clear. No connection risk, but entirely dependent on one corridor — high schedule variance.
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.
