Sit on the Right side of the plane for the best views on flights from London to Seoul. The right side delivers the London departure spectacle which is the most dramatic single moment of the flight. The polar route over Siberia offers limited differentiation between sides at cruising altitude, and the Incheon arrival views are good but less iconic. The London departure on the right side is the clear highlight of the journey.

During takeoff from Heathrow (LHR), sit on the Right side for the best views. Heathrow departures on the eastbound 09L/09R runways head east, putting central London on the right side. You get a clear view over the Thames corridor, the City, and Canary Wharf as the aircraft climbs out. The left side faces north toward the suburban sprawl of Slough and Uxbridge with little of interest. Notable sights include: Thames River bend at Kew and Richmond, Canary Wharf tower cluster, The City of London and St Paul's dome area, Windsor Castle and Great Park to the southwest during the turn.

When landing at Incheon International (ICN), sit on the Left side for the best views. Incheon approaches typically come in from the west or northwest over the Yellow Sea onto runways 15L/15R or 33L/33R. On the common westerly approach over the Yellow Sea, the left side faces south toward the Korean coastline and the Han River estuary, while the right side looks out over open water. On the 33 heading approach, the left side picks up the Seoul metropolitan skyline and the Han River valley inland. Notable sights include: Han River estuary and tidal flats near Incheon, Ganghwa Island in the Yellow Sea approach, Seoul city skyline visible inland to the east, Songdo International Business District reclaimed land near the airport.

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

The route tracks northeast over the North Sea, across southern Scandinavia or the Baltic states, then over western Russia and into Siberia. The vast Siberian taiga — endless boreal forest broken by frozen river systems including the Ob and Yenisei — dominates the mid-flight view. The route then descends toward Mongolia or northern China before crossing the Yellow Sea into Korea. At cruising altitude the Ural Mountains appear as a subtle low ridge, and the Mongolian steppe transitions visibly from forest to open grassland.
