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 when direct is unavailable or overpriced. Both legs are fully advisory-clean. Cathay Pacific's HKG hub is reliable.
BKK–HKG–ICN is advisory-clean. Adds approximately 75 minutes versus direct due to the HKG detour.
Clean, high-frequency route. Thai Airways, Korean Air, Asiana, and multiple LCCs provide strong daily capacity on this popular leisure corridor.

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.
