Sit on the Left side of the plane for the best views on flights from Denver to Vancouver. Left side wins both ends of the flight decisively. At takeoff you get the full Rocky Mountain Front Range panorama, and on approach into Vancouver you get the North Shore Mountains and the city. During the cruise over British Columbia, left side also tracks closer to the Coast Mountains interior ranges as the route curves northwest.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN typically departs northwest on runway 34L/35L or west on runway 25. A left-side seat gives you a clear view of the Front Range of the Rocky Mountains, including the prominent peaks of Mount Evans and Longs Peak rising above the foothills just west of Denver. The city grid of Denver spreads out below before the terrain rises dramatically to the west. Notable sights include: Front Range Rocky Mountains (Mount Evans at 14,265 ft, Longs Peak at 14,259 ft), Denver city grid and downtown skyline, Red Rocks Amphitheatre area in the foothills, Denver Tech Center sprawl to the south.

When landing at Vancouver International (YVR), sit on the Left side for the best views. YVR approaches typically come from the east or southeast on runway 08L/08R, meaning the aircraft tracks westward over the Fraser Valley before turning over the Strait of Georgia. Left-side seats get the best view of the North Shore Mountains — the Garibaldi Range and the distinctive twin peaks of The Lions above Vancouver — plus the city of Vancouver itself and English Bay. Right side faces south toward the flat Fraser Delta farmland. Notable sights include: North Shore Mountains (Garibaldi Range, The Lions peaks), Vancouver city and English Bay, Strait of Georgia, Fraser River delta farmland patchwork.

The flight from Denver International (DEN) to Vancouver International (YVR) takes Approximately 2 hours 45 minutes to 3 hours.

The flight crosses southern Wyoming's high desert plains, then enters Idaho and Montana terrain including the Snake River Plain. Over central British Columbia the route passes over the Columbia Mountains and the Okanagan Highlands. The Canadian Rockies and Interior Plateau of BC are visible as the aircraft descends toward the coast, with the Fraser Canyon cutting through the Coast Mountains just before the Fraser Valley opens up near Vancouver.
