Sit on the Left side of the plane for the best views on flights from Frankfurt to Copenhagen. Left side wins both takeoff and landing. During the cruise phase heading roughly north-northeast, the left side also tracks over the German interior giving views of the North German Plain, and on descent you get the Øresund and Copenhagen approach. Right side has little to offer beyond open sea and flat farmland throughout.

During takeoff from Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt uses runway 25L/25C for westward departures frequently, then aircraft turn northward. A left-side seat captures the Frankfurt city skyline and the Main River as you climb out. The Taunus hills to the north are visible on the left as the aircraft turns toward the departure heading. Notable sights include: Frankfurt city skyline (Bankenviertel), Main River bend, Taunus hills, Rhine-Main flatlands.

When landing at Kastrup (CPH), sit on the Left side for the best views. Copenhagen Kastrup typically uses runways 22L/22R for southwesterly approaches or 04 for northeasterly approaches. On the common runway 22 approach, aircraft come in from the northeast over the Øresund strait. A left-side seat gives a clear view of central Copenhagen, the harbor, and the Øresund Bridge connecting Denmark to Sweden. Notable sights include: Øresund Bridge, Copenhagen harbor and city center, Amager Fælled (flat island terrain), Malmö coastline across the strait.

The flight from Frankfurt Main (FRA) to Kastrup (CPH) takes Approximately 1 hour 30 minutes.

The route crosses the North German Plain — flat, agricultural, with the Elbe River visible as a major waterway. Over Schleswig-Holstein the terrain remains low and open with scattered lakes and the Jutland Peninsula coastline visible. The flight then crosses the narrow Fehmarn Belt or Kattegat waters before descending over the Danish islands toward Copenhagen.
