This routing avoids all known warning areas and conflict zones on the Asia-Europe corridor. It ranks well compared to alternatives that pass through or near disrupted airspace in the Middle East and Central Asia.
Seoul hub rated 0/3 (world-class) — Incheon is one of the world's most resilient transit hubs with excellent onward connections throughout Northeast Asia.
The Seoul to Tokyo second leg is only ~2.5 hours over clean Korean/Japanese airspace — dramatically shorter and less corridor-exposed than Istanbul to Tokyo (~9 hours through Central Asia).
London to Seoul first leg uses the Central Asian corridor. This is the same exposure as the Istanbul option on the first leg — but the hub break at Seoul provides recovery optionality.
Korean Air operates 2 daily London to Seoul departures with 10+ daily Seoul to Tokyo frequencies — strong second-leg rebooking depth.
Total journey with a normal layover runs approximately 14.5 hours. On a clear day the direct BA/JAL flight is slightly faster; via Seoul offers a better hub.
