Sit on the Left side of the plane for the best views on flights from Oslo to Frankfurt. Left side delivers the best views at both ends of the flight — Lake Mjøsa on departure and Frankfurt's skyline plus the Rhine on approach. During cruise over Germany, the left side also faces south toward the Ruhr valley and central German landscape as the route tracks southwest.

During takeoff from Oslo Gardermoen (OSL), sit on the Left side for the best views. Gardermoen's primary departure runway 01L/19R means southbound departures head roughly south. A left-seat (east-facing) window gives views over the Mjøsa lake — Norway's largest — and the forested Hedmarken plateau as the aircraft climbs and turns southwest toward the continent. Notable sights include: Lake Mjøsa (Norway's largest lake, clearly visible to the east), Hamar town on Mjøsa's eastern shore, the Hedmarken forested plateau, Oslo's eastern suburbs and Oslofjord visible briefly to the southwest.

When landing at Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt typically uses runways 25L/25C for westward landings, meaning the approach comes from the east over the Rhine-Main region. A left-seat (south-facing) window on approach gives clear views of the Rhine River, the Taunus hills to the north, and Frankfurt's distinctive skyline as you descend over the city. Notable sights include: Frankfurt city skyline (Bankenviertel skyscrapers clearly visible), Rhine River and Main River confluence near Mainz, Taunus hill range to the north, Wiesbaden and Mainz urban areas along the Rhine.

The flight from Oslo Gardermoen (OSL) to Frankfurt Main (FRA) takes Approximately 2 hours 10 minutes.

The route crosses southern Scandinavia over the Danish straits and Jutland peninsula, then enters northern Germany over Schleswig-Holstein. The flight tracks roughly southwest over the North German Plain — flat, heavily farmed lowlands with the Elbe River crossing visible near Hamburg. Further south the landscape rises slightly into the Hessian highlands before descending into the Rhine-Main basin at Frankfurt.
