Sit on the Left side of the plane for the best views on flights from Copenhagen to Helsinki. While takeoff favors the right, the landing view from the left—approaching over the Finnish archipelago and Gulf of Finland—is more visually distinctive and memorable. The archipelago's intricate island pattern and the water approach are the flight's most striking geographic features.

During takeoff from Kastrup (CPH), sit on the Right side for the best views. Right side seats capture the Øresund Strait and the Swedish coast as you climb northeastward. CPH typically departs runways 04L/04R or 22L/22R; northeasterly departures show the water crossing and Malmö's urban sprawl across the sound. Notable sights include: Øresund Strait, Malmö city (Sweden, south side of sound), Amager Island (Copenhagen's eastern district), Kastrup industrial area.

When landing at Helsinki Vantaa (HEL), sit on the Left side for the best views. Left side provides the best approach view of the Finnish archipelago and the descent into Helsinki. HEL typically uses runways 04L/04R or 22L/22R; southwesterly approaches show the island-dotted Gulf of Finland and the approach path over water. Notable sights include: Gulf of Finland (Suomenlahti), Finnish archipelago islands, Vantaa city (northern Helsinki), Lake Tuusula (inland, visible before final descent).

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

The flight crosses the Baltic Sea at roughly 58°N, passing over open water with no major landmarks visible. The route tracks northeast across the Gulf of Bothnia's southern approaches. Approximately 30 minutes into the flight, you may glimpse the Swedish coast receding to the west (left), and 45 minutes in, the Finnish coastline begins to appear on the right. The Åland Islands (autonomous Swedish-speaking region) lie south of the direct route but are occasionally visible in clear conditions as low-lying archipelago terrain around 60°N, 20°E.
