Sit on the Left side of the plane for the best views on flights from Boise to Denver. Left side wins both ends of the flight. During the cruise portion heading southeast, the left side also tracks closer to the Sawtooth Range remnants and the high terrain of central Idaho early in the flight, and later gives better angles on the Colorado Rockies as you approach Denver.

During takeoff from Boise Air Terminal (BOI), sit on the Left side for the best views. Departing Boise typically heads east or southeast. The left (north) side gives you a clear look back at the Boise Front foothills and the Boise River valley cutting through the city. You also get a better angle on Lucky Peak Reservoir as the aircraft climbs and turns. Notable sights include: Boise River valley, Lucky Peak Reservoir, Boise Front foothills, downtown Boise grid.

When landing at Denver International (DEN), sit on the Left side for the best views. Denver International sits on the plains east of the Rockies. On approach from the west, the left side faces south and gives you a sustained view of the entire Front Range — from Pikes Peak in the south to Longs Peak in the north — as the aircraft descends over the plains. The right side faces north toward open prairie with far less visual interest. Notable sights include: Rocky Mountain Front Range, Longs Peak, Pikes Peak (distant), Denver metro skyline.

The flight from Boise Air Terminal (BOI) to Denver International (DEN) takes Approximately 1 hour 30 minutes to 1 hour 45 minutes.

After leaving Boise, the route crosses the Snake River Plain and the high desert of southern Idaho, then passes over the rugged terrain of the Sawtooth and Smoky Mountains to the north. Crossing into Utah airspace, the Great Salt Lake Desert and Wasatch Front may be visible to the south. Over western Colorado, the route crosses the Uinta Basin and the Book Cliffs before the Colorado Rockies come into view on descent toward Denver.
