Sit on the Left side of the plane for the best views on flights from Denver to Everett. Left side wins at both ends of the flight. During the cruise over Idaho and eastern Washington, the left side also tracks closer to the Cascade Range foothills and offers glimpses of volcanic peaks like Mount Adams on approach into the Pacific Northwest.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN's primary departure runway 35L/34R sends aircraft northwest, putting the entire Front Range and Rocky Mountain wall on the left side. You get a sweeping view of the Rockies from Pikes Peak in the south up through the Indian Peaks and beyond as you climb out heading northwest. Notable sights include: Front Range Rocky Mountains, Denver metro grid, Pikes Peak (south), Longs Peak and Indian Peaks (northwest).

When landing at Snohomish Co (PAE), sit on the Left side for the best views. PAE sits just east of Puget Sound, and aircraft typically approach from the south or southeast on runway 34L/34R heading northwest. A left window seat gives you views over Puget Sound, the Seattle skyline to the south, and the Olympic Mountains across the water to the west. Notable sights include: Puget Sound, Seattle skyline (south), Olympic Mountains (west across the Sound), Cascade foothills (east).

The flight from Denver International (DEN) to Snohomish Co (PAE) takes Approximately 2 hours 15 minutes to 2 hours 30 minutes.

After crossing the Rockies, the flight tracks northwest over Wyoming's high desert basin, then crosses into southern Idaho over the Snake River Plain. The broad flat lava fields and agricultural pivot-irrigation circles of the Snake River Plain are visible mid-flight. Approaching Washington, the Columbia Plateau's dry channeled scablands give way to the Cascade foothills. On clear days, Mount Rainier and Mount Adams are visible to the left as you descend into the Puget Sound lowlands.
