All 2 assessed routes are currently rated Flowing.
Via Singapore scores highest on this corridor — clean airspace routing, with moderate detour impact.
Limited coverage — fewer corridor options than usual.
NRT–CGK via Singapore, routing south over the East China Sea and South China Sea into SIN then a short hop to Jakarta. Fully advisory-clean throughout — avoids all advisory zones. Singapore Airlines operates the anchor NRT–SIN service; Garuda Indonesia and SQ provide SIN–CGK. The SIN hub is well-suited for Japan–Indonesia connections with high frequency.
East China Sea and South China Sea transit are fully advisory-clean. SIN–CGK is operationally routine. Monitor SIN connection timing for tight schedule windows.
NRT–CGK via Hong Kong, flying southwest over East China Sea to HKG then south through South China Sea into Indonesia. Fully advisory-clean — avoids all current advisory zones. Cathay Pacific provides reliable NRT–HKG connections with daily HKG–CGK service. Alternative to the SIN routing when Cathay Pacific schedules provide a better connection window.

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.
