Not every flight from Paris to Tokyo takes the same path right now.
4 routes assessed for this corridor. Via Istanbul scores highest.
Via Istanbul — lower exposure than Gulf-connected options, with moderate detour impact and reasonable hub reliability.
Better structural resilience than the direct Central Asian routing by breaking the journey at Istanbul. IST–NRT still uses Central Asian corridor, but the hub break gives routing flexibility.
Limited alternative paths if the main corridor is disrupted
IST–NRT second leg traverses the Central Asian corridor — same exposure point as the direct flight, but you have a natural decision point at Istanbul to assess conditions before continuing.
Air China's China-side option for CDG→NRT. PEK→NRT is a short, clean segment (~3 hours) over Yellow Sea airspace. The CDG→PEK first leg uses the Central Asian corridor — same structural constraint as Via Istanbul on this pair.
Best structural resilience for CDG→NRT. Cathay routes CDG–HKG south via the Middle East/South Asia corridor, bypassing Central Asian congestion entirely. Trade-off: longer distance and Middle East advisory exposure on the first leg.
Active disruptions
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.
