Via Istanbul is the best route right now.
Based on official airspace warnings · checked 3h ago · How this works
Full breakdown →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.
Very few backup paths if this route is disrupted
Route assessed 21h ago
Full breakdown →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.

Full breakdown →The top option avoids the warning area this route crosses.
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.
