Via Hong Kong is the best route right now.
Based on official airspace warnings · checked 4h ago · How this works
Full breakdown →Best structural option for LHR→NRT. Cathay routes LHR–HKG via South Asia, bypassing the Central Asian corridor entirely. HKG–NRT is a clean northeast Asian segment.
This route is significantly longer than a more direct path
Route assessed 22h ago
Full breakdown →Strong alternative to Via Istanbul. ICN hub scores 0/3 (world-class) and the ICN→NRT second leg is only 2.5 hours over clean Pacific airspace — much shorter than IST→NRT. First leg uses the Central Asian corridor.
Very few backup paths if this route is disrupted
