Sit on the Left side of the plane for the best views on flights from Copenhagen to Frankfurt. The left side delivers the Øresund Bridge on departure and the Frankfurt skyline with the Main river on approach. The right side offers relatively featureless Baltic and North German plain for most of the flight. Left wins both ends of this route.

During takeoff from Kastrup (CPH), sit on the Left side for the best views. CPH typically departs on runway 22L/22R heading southwest, which puts the left side facing southeast over the Øresund strait and the Swedish coast. You get a clear view of the Øresund Bridge connecting Denmark and Sweden, one of the most recognizable structures in Scandinavia. Notable sights include: Øresund Bridge (Denmark-Sweden link), Malmö city waterfront across the strait, Amager Fælled wetlands below, Copenhagen city center and harbour to the north.

When landing at Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt typically lands on runway 25L/25C/25R from the east, meaning the aircraft approaches heading west. The left side faces south, giving views over the Taunus hills, the Frankfurt skyline to the north, and the Main river valley. On a southerly approach variant, the left side captures the Rhine-Main plain and the city's distinctive cluster of skyscrapers. Notable sights include: Frankfurt city skyline (Bankenviertel skyscrapers), Main river winding through the city, Taunus hills to the north, Rhine-Main flatlands.

The flight from Kastrup (CPH) to Frankfurt Main (FRA) takes Approximately 1 hour 45 minutes to 2 hours.

The route tracks southwest over the flat North German Plain — Schleswig-Holstein farmland, the Hamburg metropolitan area visible to the right around the midpoint, the Elbe river crossing near Hamburg, then transitioning into the rolling hills of Hesse as you approach Frankfurt. No significant mountain ranges on this route — it is predominantly low-lying agricultural terrain with river valleys.
