Not every flight from Hong Kong to Delhi takes the same path right now.
All 2 assessed routes are currently rated Flowing.
Via Bay of Bengal — clean airspace routing, with minimal detour impact and strong hub reliability.
Limited coverage — fewer corridor options than usual.
Primary HKG–DEL routing tracks southwest over the South China Sea, crosses Myanmar FIR, transits the Bay of Bengal, and enters India via eastern FIRs. Airspace_score 0 — avoids Central Asian FIRs, Iranian FIR, and Pakistani FIR entirely. Cathay Pacific, Air India, and IndiGo all operate non-stop on this corridor. Bay of Bengal routing is the standard industry choice under all advisory conditions.
Myanmar FIR (VYYY) — generally advisory-clean for overflights; verify current NOTAM status. Bay of Bengal transit and India entry are fully advisory-clean.
Northern HKG–DEL variant tracking northwest over China FIR, through Central Asian FIRs, and into Delhi. Airspace_score 1 for Central Asian FIR congestion and Iranian FIR proximity on the western approach. The Bay of Bengal direct is shorter, advisory-cleaner, and the industry standard — this northern routing only appears in exceptional filings.

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.
