Sit on the Right side of the plane for the best views on flights from Toronto to Denver. The left seat wins at takeoff for the Toronto skyline and lake views, but the right seat delivers the more dramatic and sustained payoff — the Rocky Mountain Front Range panorama on approach into Denver is one of the most spectacular arrivals in North America. If you can only pick one side for the whole flight, right side wins for the landing alone.

During takeoff from Buttonville Muni (YKZ), sit on the Left side for the best views. Buttonville's primary runway 15/33 means departures heading northwest or south. A westbound departure toward DEN will typically involve a left turn after takeoff, putting the left side over downtown Toronto, Lake Ontario, and the CN Tower. The right side faces suburban sprawl to the north and east with little of interest. Notable sights include: CN Tower and downtown Toronto skyline, Lake Ontario shoreline, Toronto Islands, Pearson International Airport to the west.

When landing at Denver International (DEN), sit on the Right side for the best views. Denver International sits east of the city, and aircraft typically land from the east heading west on runways 16L/R or 34L/R. On approach from the east heading westbound, the right side faces south and southwest, giving a clear panoramic view of the entire Front Range — the Rocky Mountain wall from Pikes Peak in the south to Longs Peak in the north. The left side looks north over flat plains. Notable sights include: Front Range of the Rocky Mountains, Pikes Peak to the south, Longs Peak to the north, Denver city skyline against the mountain backdrop.

The flight from Buttonville Muni (YKZ) to Denver International (DEN) takes Approximately 3 hours 30 minutes to 4 hours depending on winds and routing.

The flight tracks southwest over Lake Erie's southern shore, then across Ohio and Indiana farmland, over Chicago's southern suburbs, across the flat Illinois and Iowa corn belt, over the Missouri River valley near Omaha, then across the Nebraska Sandhills and the high plains of eastern Colorado before the dramatic Front Range reveal on descent. The terrain is largely flat agricultural land for the middle two hours, with the gradual rise of the Great Plains visible as the aircraft approaches Colorado.
