All 3 assessed routes are currently rated Flowing.
Via Hong Kong — clean airspace routing, with moderate detour impact and strong hub reliability.
Advisory-clean NRT–DEL routing via Hong Kong. The NRT–HKG leg tracks southwest over the East China Sea — advisory-clean. The HKG–DEL leg routes northwest over the South China Sea and Myanmar, avoiding Central Asian FIRs. Cathay Pacific provides reliable NRT–HKG–DEL connections. Preferred when Central Asian advisories are elevated. Adds ~1.3h versus the Central Asia direct.
NRT–HKG–DEL is fully advisory-clean. Verify Cathay Pacific HKG–DEL schedule for adequate connection time after the NRT–HKG leg.
Fully advisory-clean NRT–DEL routing via Singapore. The NRT–SIN leg routes south through Southeast Asian FIRs — clean throughout. The SIN–DEL leg tracks northwest over the Indian subcontinent. Singapore Airlines operates both legs. Longest routing at ~10.3h; preferred when both Central Asian advisories and northern alternatives carry elevated notices.
The primary NRT–DEL routing tracks westbound across China and Central Asian FIRs before descending into India. Air India, JAL, and ANA all operate direct service. Airspace_score 1 for Central Asian FIR congestion and Iranian FIR proximity on the western segment as the aircraft approaches DEL. When Central Asian FIR advisories are stable this is the fastest option at ~7.3h.

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.
