~12h 55m

Best for

Korean Air's NRT→LHR option via Incheon. ICN sits naturally westward from Tokyo on the path to Europe — minimal geometric deviation. ICN hub is world-class (0/3); ICN→LHR uses Central Asian corridor with a natural hub recovery point.

Weakness

Limited alternative paths if the main corridor is disrupted

Watch

ICN→LHR uses the Central Asian corridor. Check ATFM restrictions before departure. NRT→ICN over East Sea airspace is clean and uncongested.

Evaluated using advisory airspace exposure, corridor sensitivity, detour impact, and hub routing logic — based on EASA and national authority advisories.
