Sit on the Right side of the plane for the best views on flights from Seoul to London. The right side delivers the more dramatic and varied departure sequence over Seoul and the Korean Peninsula's mountain spine. The landing views on the left are excellent over London, but the right side also picks up good views of Siberian river systems and Scandinavian coastline during the cruise, making it the stronger overall choice for the full journey.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. ICN departures on runway 15R/33L or 16/34 typically head northward or westward over the Yellow Sea. A right-side seat gives you views back toward Seoul and the Han River basin as you climb, plus the mountainous spine of the Korean Peninsula to the east. Left side faces open water almost immediately. Notable sights include: Han River and Seoul city grid to the east, Bukhansan granite peaks northeast of Seoul, Gyeonggi Bay and the tidal flats of the Yellow Sea below, Incheon Bridge visible near the airport.

When landing at Heathrow (LHR), sit on the Left side for the best views. Heathrow arrivals from the east typically use westward runways (09L/27R or 09R/27L), meaning the approach track comes in over central London. A left-side seat on this westbound approach gives a clear view of the Thames, central London landmarks, and the city grid as you descend through 3,000-5,000 feet over the eastern and central city. Notable sights include: Thames River winding through central London, Canary Wharf tower cluster in Docklands, The City of London and its skyline, Windsor Castle and the Thames Valley on final approach.

The flight from Incheon International (ICN) to Heathrow (LHR) takes Approximately 11 to 12 hours.

The route tracks northwest from Korea across the Yellow Sea, then over northeastern China and into Siberia crossing the Amur River basin. The flight passes over the vast boreal taiga of central Siberia with the Ob and Yenisei river systems visible as enormous braided waterways cutting through flat forested plains. Crossing into Europe, the Ural Mountains appear as a low, broad ridge — modest in height but clearly distinct from the plains on either side. The route then descends over Scandinavia, crossing southern Norway or Denmark before tracking south over the North Sea toward England.
