Sit on the Left side of the plane for the best views on flights from Oslo to Helsinki. While takeoff favors the right for Oslofjord views, the landing approach on the left provides more dramatic and distinctive geography—the Gulf of Finland, archipelago, and Finnish lake landscape are more visually striking than the inland forest views on the right during descent.

During takeoff from Oslo Gardermoen (OSL), sit on the Right side for the best views. OSL typically departs runway 01L/01R (northbound) or 19L/19R (southbound). Right-side seats offer views of the Oslofjord's eastern shoreline and the forested terrain of Akershus immediately after departure. Left seats face inland toward less distinctive forest. Notable sights include: Oslofjord (eastern arm), Akershus forest belt, Lake Mjøsa (visible at distance on clear days), Oslo city sprawl receding southward.

When landing at Helsinki Vantaa (HEL), sit on the Left side for the best views. HEL typically lands runway 04R/04L (eastbound) or 22R/22L (westbound). Left-side seats during approach offer views of the Gulf of Finland's northern coast, the Sipoo archipelago, and the distinctive landscape of southern Finland with its lakes and forest patterns. Right seats face inland forest with fewer distinctive features. Notable sights include: Gulf of Finland (northern shore), Sipoo archipelago and skerries, Lake Tuusula (visible inland), Helsinki city district spreading across peninsulas.

The flight from Oslo Gardermoen (OSL) to Helsinki Vantaa (HEL) takes Approximately 1 hour 15 minutes.

The flight path crosses the Swedish-Norwegian border near the Göta älv region, then continues southeast over Swedish territory (Värmland and Södermanland provinces with their characteristic lakes and forest), before crossing into Finland near the Turku archipelago region. The entire route remains over boreal forest and lake systems with occasional glimpses of larger water bodies. No major mountain ranges are visible; the terrain is relatively low-lying throughout.
