Sit on the Right side of the plane for the best views on flights from Paris to Calgary. While the left side wins at takeoff for the Paris cityscape, the right side delivers the Rocky Mountain Front Range on approach into Calgary, which is the single most spectacular visual moment of the entire flight. Over the Atlantic and Greenland the views are similar on both sides, but the right side also gets slightly better angles on Greenland's ice sheet during the mid-flight polar routing.

During takeoff from Charles De Gaulle (CDG), sit on the Left side for the best views. CDG departures heading west on runway 27L/27R put Paris city center on the left side. You get a clear view south over the Seine bends, the Eiffel Tower area, and the dense urban grid of central Paris before the aircraft climbs out over the western suburbs. Notable sights include: Seine river bends through Paris, Eiffel Tower district (Champ de Mars area), La Défense business district towers, Versailles palace and gardens to the southwest.

When landing at Calgary International (YYC), sit on the Right side for the best views. YYC typically uses runways 35L/35R for northbound arrivals, meaning the aircraft approaches from the south. The right side faces west, giving a direct view of the Rocky Mountain Front Range — the most dramatic visual feature of any approach into Calgary — with the Bow River valley and downtown Calgary visible below on descent. Notable sights include: Rocky Mountain Front Range (including Mount Yamnuska and the Fairholme Range), Bow River valley, downtown Calgary skyline, Nose Hill Park plateau.

The flight from Charles De Gaulle (CDG) to Calgary International (YYC) takes Approximately 9 to 10 hours.

The flight tracks northwest over the English Channel, then across southern England or Ireland, then out over the North Atlantic on a great circle route. Mid-flight passes over or near the southern tip of Greenland with its massive ice sheet and fjords visible on clear days. The route then crosses the Davis Strait and Baffin Island or northern Quebec, with the Canadian Shield's lake-dotted boreal forest below. As the aircraft descends into Alberta, the flat prairies give way to the dramatic transition at the Rocky Mountain foothills.
