Sit on the Left side of the plane for the best views on flights from Copenhagen to Seoul. While takeoff favors the right for Øresund Strait views, the landing approach on the left provides more sustained and dramatic scenery—the Yellow Sea, harbor infrastructure, and Songdo's modern skyline. The landing experience outweighs the takeoff advantage.

During takeoff from Kastrup (CPH), sit on the Right side for the best views. Copenhagen typically departs eastbound (runways 04L/04R or 22L/22R depending on wind). Right-side seats face the Øresund Strait and Swedish coast during initial climb, offering clear water and landmass contrast. Left side shows inland Danish terrain with less dramatic relief. Notable sights include: Øresund Strait (water body separating Denmark and Sweden), Malmö city (visible on Swedish side), Amager Island (immediate foreground), Tåsinge and Langeland islands (southeast in distance).

When landing at Incheon International (ICN), sit on the Left side for the best views. Incheon typically lands westbound (runways 16L/16R or 34L/34R). Left-side seats during approach offer views of the Yellow Sea, Incheon's harbor infrastructure, and the reclaimed land where the airport sits. Right side shows inland Korean terrain with less distinctive features during final approach. Notable sights include: Yellow Sea (water body), Incheon harbor and port facilities, Songdo International Business District (modern high-rises on reclaimed land), Ganghwa Island (visible to north during descent).

The flight from Kastrup (CPH) to Incheon International (ICN) takes Approximately 9.5 to 10.5 hours.

The flight path crosses the Baltic Sea (north of Poland), then transitions over Belarus and western Russia. Notable midpoint features include the Baltic coastline near Kaliningrad (visible during early cruise), the vast Russian steppe and taiga forests (appearing as uniform green or brown depending on season), and the Ural Mountains as a distant ridge on the horizon around the 5-6 hour mark. Later, the flight crosses Kazakhstan's steppes, then the Altai Mountains region. As the aircraft approaches East Asia, the Gobi Desert and Mongolian plateau become visible, followed by the North China Plain and finally the Korean Peninsula's mountainous spine (Taebaek Mountains) before descent into Incheon.
