Sit on the Left side of the plane for the best views on flights from Vancouver to Denver. Left side dominates the full flight. At takeoff you get the Fraser Delta, Vancouver skyline, and North Shore mountains. Through the cruise you track southeast over the Okanagan highlands, the Columbia River basin, and the Idaho-Montana Rockies — all better framed on the left. On descent into Denver the left side shows the city grid clearly while the right gets the Front Range, but the takeoff and cruise views tip the balance firmly left.

During takeoff from Vancouver International (YVR), sit on the Left side for the best views. YVR's primary departure runway 26L sends aircraft westward over the Fraser River mouth before turning southeast. Left side passengers get a clear view back over the Fraser Delta, Richmond, and the North Shore mountains including the Garibaldi massif. The right side faces south toward the flat farmland of Delta and the US border. Notable sights include: Fraser River delta and its braided channels, North Shore mountains (Grouse, Seymour, Cypress), Mount Garibaldi to the northeast, downtown Vancouver skyline across Burrard Inlet.

When landing at Denver International (DEN), sit on the Left side for the best views. DEN's primary arrival from the north typically uses runways 34L/34R, bringing aircraft in from the north-northwest on a southward heading. Left side passengers face east toward the flat plains and can see the Denver metro grid clearly. Right side gets the Front Range and Rocky Mountains — but left still wins overall for the flight because of the superior takeoff views. Notable sights include: Denver metro grid and downtown skyline, Rocky Mountain Front Range (Longs Peak, Mount Evans visible to the west), Denver International Airport's distinctive white tent roof structure, South Platte River corridor through the metro.

The flight from Vancouver International (YVR) to Denver International (DEN) takes Approximately 2 hours 30 minutes to 2 hours 50 minutes.

The route passes over the Okanagan Valley and its lakes in southern BC, then crosses the Selkirk and Purcell mountain ranges of eastern BC and northern Idaho, followed by the broad Snake River Plain of southern Idaho, then the high desert plateau of southwestern Wyoming before descending toward the Colorado Front Range and Denver.
