Sit on the Left side of the plane for the best views on flights from Frankfurt to Seoul. Left side wins both ends of the flight. At departure you get the Frankfurt skyline and Main River, and at arrival you get the Yellow Sea tidal approach and Han River estuary. During the cruise over Siberia, left side also faces generally south toward the more populated and geographically varied terrain.

During takeoff from Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt airport's primary departure runway 25C/25L sends aircraft westward before turning north, putting the left side over the Rhine-Main basin and the city of Frankfurt itself. You get a clear view of the Frankfurt skyline, the Main River bends, and the Taunus hills to the north. Notable sights include: Frankfurt city skyline and Bankenviertel towers, Main River bends through the city, Taunus hill range to the north, Sachsenhausen district and Alte Brücke.

When landing at Incheon International (ICN), sit on the Left side for the best views. Incheon airport sits on Yeongjong Island and aircraft typically approach from the west over the Yellow Sea on runway 15L/15R heading southeast. The left side gives you the view over the Yellow Sea tidal flats and the approach over the island's western shore, while also revealing the Han River estuary and the distant Seoul skyline to the east. Notable sights include: Yellow Sea tidal mudflats west of Yeongjong Island, Han River estuary and Ganghwa Island, Incheon city waterfront and reclaimed land, distant Seoul skyline on the eastern horizon.

The flight from Frankfurt Main (FRA) to Incheon International (ICN) takes Approximately 11 to 12 hours.

The route tracks northeast over Poland and the Baltic states, then across western Russia and into Siberia over the Ural Mountains, crossing the vast West Siberian Plain, then over Lake Baikal region, descending across northeastern China and Manchuria, crossing the Yellow Sea before arriving at Incheon. Lake Baikal is the single most dramatic visible feature at cruise altitude — its elongated dark blue shape is unmistakable against the Siberian landscape roughly at the flight midpoint.
