Sit on the Left side of the plane for the best views on flights from Montreal to Denver. While the takeoff offers pleasant river and mountain views, the landing descent into Denver provides more dramatic and visually distinctive scenery. The Rocky Mountains' scale and the sharp transition from plains to peaks create a more memorable window experience than the departure from Montreal.

During takeoff from St Hubert (YHU), sit on the Right side for the best views. Right-side seats offer views of the St. Lawrence River valley and the Laurentian Mountains as the aircraft climbs westward. The river's distinctive meanders and the forested ridge line of the Laurentians are clearly visible during the initial climb-out phase. Notable sights include: St. Lawrence River, Laurentian Mountains, Montreal urban sprawl to the south, Île Perrot.

When landing at Denver International (DEN), sit on the Left side for the best views. Left-side seats provide excellent views of the Rocky Mountains during the descent into Denver. The Front Range peaks, including Mount Evans and the Continental Divide, are prominently visible on the western approach. The transition from the Great Plains to mountainous terrain is dramatic and clearly defined. Notable sights include: Rocky Mountains Front Range, Mount Evans, South Platte River valley, Denver metropolitan area.

The flight from St Hubert (YHU) to Denver International (DEN) takes Approximately 4 hours 15 minutes.

The flight path crosses the Great Lakes region (Lake Michigan visible on the northern route), then transitions over the American Midwest. Notable midpoint features include the Mississippi River valley (if visible during cruise), the transition from deciduous forests to grasslands around Iowa/Missouri, and the gradual rise of terrain as the aircraft approaches the High Plains of eastern Colorado. The Platte River valley becomes visible roughly 90 minutes before landing, marking the final approach to the Rocky Mountains.
