Via Hong Kong scores highest on this corridor — clean airspace routing, with moderate detour impact.
Limited coverage — fewer corridor options than usual.
Clean alternative via HKG for when direct fares are high or schedules don't suit. Both legs are fully advisory-clean.
SIN–HKG–ICN is advisory-clean. Adds ~75 minutes versus direct due to the northern detour through HKG.
Clean, high-frequency route over the South China Sea and Philippine Sea. Multiple carrier options with strong rebooking depth at both ICN and SIN.

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.
