Sit on the Left side of the plane for the best views on flights from Spokane to Denver. Left side wins both takeoff and landing. During the cruise portion heading south-southeast, the left side also tracks closer to the Idaho-Montana border ranges early on and then offers oblique views toward the Tetons and Wind River Range in Wyoming as distant horizon features. The right side faces east toward the Great Plains for most of the flight.

During takeoff from Spokane International (GEG), sit on the Left side for the best views. Spokane typically departs runway 21 (heading southwest) or runway 3 (heading northeast). On a southbound flight to Denver, expect a southwesterly departure or a turn south shortly after. Left side gives you the Spokane River valley, downtown Spokane, and views toward the Palouse hills. Right side faces northwest toward less distinctive terrain. Notable sights include: Spokane River gorge below downtown, Palouse farmland rolling hills to the south, Liberty Lake and Medical Lake visible as small water bodies, distant Blue Mountains on the southern horizon.

When landing at Denver International (DEN), sit on the Left side for the best views. Denver International sits east of the Rockies on the plains, and aircraft typically approach from the east or northeast on runways oriented north-south. A left window seat on approach from the north gives a clear broadside view of the entire Front Range — from Longs Peak down through the Denver metro foothills — as the aircraft descends over the plains. Right side faces east toward flat featureless prairie. Notable sights include: Front Range of the Rockies including Longs Peak and Mount Evans, Denver city skyline against the mountain backdrop, Cherry Creek Reservoir visible southeast of downtown, Rocky Mountain National Park peaks on the northern horizon.

The flight from Spokane International (GEG) to Denver International (DEN) takes Approximately 1 hour 45 minutes to 2 hours.

The flight crosses the Snake River Plain of southern Idaho, then the high desert of southwestern Wyoming including the Green River Basin. The Wind River Range is visible as a prominent snow-capped ridge to the left (east-southeast) in Wyoming. The flight then crosses northern Colorado's high plains before descending toward Denver. No significant mountain crossings — the Rockies remain largely to the left as a distant wall for much of the Wyoming and Colorado segments.
