Why book

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.

The catch

Very few backup paths if this route is disrupted

Worth knowing

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

Ranks below the direct option because the connection adds hub risk vs. BA/JAL's nonstop service. Ranks well above Gulf options because both legs avoid the advisory zone. Best used when nonstop availability is limited or Korean Air fares are compelling.

NRT→ICN is a short first leg (~1.5 hours) over clean East Sea airspace — no advisory concerns.
ICN hub rated 0/3 (world-class) with multiple daily ICN→LHR frequencies via Korean Air.
ICN→LHR uses the Central Asian corridor westbound — same routing constraint as the direct BA/JAL nonstop.
Neither leg touches the Middle East advisory zone — this routing is fully Gulf-free.
Total journey approximately 13 hours including layover. Use this when direct availability is sold out or Korean Air positioning suits your itinerary.
