~13h 10m
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.
Limited alternative paths if the main corridor is disrupted
LHR→ICN uses the Central Asian corridor — check Eurocontrol ATFM status before departure. ICN→NRT transits Korean and Japanese airspace: clean, uncongested, no active advisories.
Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
