Overview
London Heathrow to Seoul Incheon — main UK-Korea trunk. Long eastbound shift on an overnight; aircraft choice and jet-lag prep both matter.
Jet lag
8-hour eastward shift on an overnight — large enough that pre-flight schedule shifting (2 nights earlier bedtime) pays off. Arrival-day morning light at Incheon or Seoul is the lever; plan 4-5 days for full adjustment.
Build a LHR→ICN adaptation scheduleBest window side
Eastbound — for sleep, pick the window for shade. The view side varies by routing; glare management is the higher priority.
Cabin humidity
Korean Air A380 and BA A350-1000 are the comfort picks. 777-300ER is the driest of the three on an 11-hour eastbound.
