Via Hong Kong scores highest on this corridor — clean airspace routing, with moderate detour impact.
Limited coverage — fewer corridor options than usual.
CGK–NRT via Hong Kong, routing northeast over South China Sea into HKG then east over East China Sea to Japan. Fully advisory-clean corridor. Cathay Pacific provides strong CGK–HKG connections with reliable HKG–NRT service. Preferred when HKG transit times and Cathay Pacific's dense schedule offer a better connection than the SIN routing.
CGK–HKG–NRT is fully advisory-clean. Monitor HKG connection time — Cathay Pacific offers multiple CGK–HKG daily frequencies.
CGK–NRT via Singapore, routing north over the South China Sea and East China Sea into Japan. Fully advisory-clean — the corridor avoids all current advisory zones including Iranian FIR, Central Asian FIRs, and Russian airspace. Singapore Airlines and Garuda Indonesia provide good CGK–SIN connections; SQ continues SIN–NRT daily. Preferred when hub transit is acceptable and airspace minimisation is the priority.

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.
