All 2 assessed routes are currently rated Flowing.
Via Philippines Approach scores highest on this corridor — clean airspace routing, with minimal detour impact.
Limited coverage — fewer corridor options than usual.
Alternative ICN–KUL routing that tracks through Philippine FIR airspace on the southbound leg before continuing to Malaysia. Operationally equivalent to the direct South China Sea routing in advisory clearance — airspace_score 0 on both. Adds roughly 10 minutes versus the primary routing.
Philippines FIR (RPHI) is operationally clean. Monitor convective NOTAMs during typhoon season (June–November).
The primary ICN–KUL routing tracks southwest over the East China Sea and South China Sea into Malaysia. Malaysia Airlines, Korean Air, and AirAsia X all operate this corridor as their standard filing. Completely avoids all advisory zones throughout. Airspace_score 0 on all segments. The fastest and cleanest option under all advisory 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.
