Via Singapore scores highest on this corridor — clean airspace routing, with moderate detour impact.
Limited coverage — fewer corridor options than usual.
ICN–CGK via Singapore or direct. Korean Air operates ICN–CGK non-stop direct — the cleanest option with no transit stop. The via-SIN routing via Singapore Airlines is the best hub alternative, routing south over East China Sea and South China Sea. Both are fully advisory-clean with no advisory zone exposure.
ICN–CGK is fully advisory-clean regardless of routing family. South China Sea and East China Sea transit are open and advisory-clean.
ICN–CGK via Hong Kong. Cathay Pacific operates the ICN–HKG–CGK connection. Fully advisory-clean routing south over the East China Sea and South China Sea. Alternative to direct and SIN routing when Cathay Pacific schedules fit better.

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.
