Sit on the Left side of the plane for the best views on flights from Rovaniemi to Paris. The left seat wins overall because the takeoff view over the Kemijoki-Ounasjoki confluence and Rovaniemi is genuinely spectacular and unique, especially in winter. During the cruise southward over Finland, Sweden, and the Baltic, the left side also tracks closer to the Gulf of Bothnia coastline and Swedish terrain. The CDG landing advantage on the right is real but modest.

During takeoff from Rovaniemi (RVN), sit on the Left side for the best views. Rovaniemi airport runway 03/21 means southbound departures head roughly south. A left (east) seat gives you a view over the Kemijoki River valley and the town of Rovaniemi itself, including the distinctive confluence of the Kemijoki and Ounasjoki rivers which is clearly visible from low altitude. The Arctic Circle marker area and the city grid are on this side. Notable sights include: Kemijoki and Ounasjoki river confluence, Rovaniemi city center grid, Ounasvaara hill east of the city, frozen/snow-covered river channels in winter.

When landing at Charles De Gaulle (CDG), sit on the Right side for the best views. CDG arrivals from the north typically use runways 26L/26R or 27L/27R, approaching from the northeast over the Paris basin. A right (north) seat on final approach gives views over the northern Paris suburbs, the A1 motorway corridor, and potentially the Seine valley. The left side faces south toward open farmland with less to see. Notable sights include: Northern Paris suburban sprawl, A1 autoroute corridor, Seine river bends northwest of Paris, Stade de France visible in Saint-Denis on close approach.

The flight from Rovaniemi (RVN) to Charles De Gaulle (CDG) takes Approximately 3 hours 30 minutes to 4 hours.

The flight tracks south-southwest over the Finnish boreal forest, crossing into Sweden over Lapland. Over central Sweden the terrain shows lakes and forest typical of the Norrland plateau. The flight crosses the Gulf of Bothnia or passes near it depending on routing, then transits Denmark or the southern Baltic, crossing Germany or the Low Countries before descending into the Paris basin over flat agricultural northern France.
