Sit on the Left side of the plane for the best views on flights from Copenhagen to Helsinki. While takeoff favors the right (Øresund Strait views), the landing approach over the Gulf of Finland and Helsinki archipelago is more visually distinctive and extended. Left-side seats capture the archipelago's complexity and Suomenlinna fortress, making the overall journey more rewarding on the left.

During takeoff from Kastrup (CPH), sit on the Right side for the best views. Right-side seats offer views of the Øresund Strait and Swedish coast during northbound climb-out. CPH typically departs runways 04L/04R or 22L/22R; northbound departures (04L/04R) provide immediate views of the water crossing toward Sweden. Notable sights include: Øresund Strait, Malmö skyline (Sweden, across the sound), Amager Island (Copenhagen's eastern district), Tåsinge Island.

When landing at Helsinki Malmi (HEM), sit on the Left side for the best views. Left-side seats capture the approach over the Gulf of Finland and Helsinki's archipelago. HEM approaches typically use runways 04 or 22; southbound approaches (runway 22) descend over the eastern archipelago and inner harbor, providing extended water and island views. Notable sights include: Gulf of Finland, Helsinki archipelago (Suomenlinna fortress island visible), Vantaa industrial area, Lake Tuusula (inland).

The flight from Kastrup (CPH) to Helsinki Malmi (HEM) takes Approximately 1 hour 15 minutes.

The flight crosses the Baltic Sea at roughly 60 miles altitude. Notable midpoint geography includes the Swedish east coast (Uppland region) passing to the left, the open Baltic waters with occasional cargo ship traffic, and the approach to the Finnish coast near the Turku archipelago before turning northeast toward Helsinki. No major mountain ranges are visible; the terrain is uniformly low-lying Nordic landscape with scattered islands throughout.
