Not every flight from Delhi to Hong Kong 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 DEL–HKG routing tracks southeast from Delhi, crossing the Bay of Bengal, Myanmar FIR, and South China Sea before reaching Hong Kong. Airspace_score 0 — completely avoids Iranian FIR, Pakistani FIR, and Central Asian FIRs. Cathay Pacific, Air India, and IndiGo operate non-stop service. The southeastern Bay of Bengal routing is the standard industry choice under all advisory conditions.
Myanmar FIR (VYYY) overflight — generally advisory-clean; verify current NOTAMs. Bay of Bengal and South China Sea transit are fully advisory-clean.
Northern DEL–HKG variant routing northwest from Delhi then east across Central Asian FIRs and through China. Airspace_score 1 for Central Asian FIR congestion and Iranian FIR proximity near departure. Bay of Bengal routing is shorter, advisory-cleaner, and the industry standard for DEL–HKG.

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.
