Sit on the Left side of the plane for the best views on flights from Columbus to Denver. The left side misses the Columbus departure views but delivers the dominant spectacle of the flight: the full Rocky Mountain Front Range panorama on descent into Denver, which is far more dramatic than anything on the right side. Midway across Kansas the left side also gives slightly better angles on the flat river valleys below.

During takeoff from Port Columbus International (CMH), sit on the Right side for the best views. CMH typically departs west on runway 28L/28R, so the right (north) side gives you a clear view back over downtown Columbus and the Scioto River as you climb out. You'll see the grid of the city center and the river corridor before the aircraft turns westward. Notable sights include: Downtown Columbus skyline, Scioto River, Ohio State University campus (large oval stadium visible), Hoover Reservoir to the northeast.

When landing at Denver International (DEN), sit on the Left side for the best views. DEN predominantly lands from the east on runways 34L/34R or 35L/35R, with aircraft approaching from the east and touching down heading north or northwest. The left (west/southwest) side delivers the full panoramic view of the Front Range — the Rocky Mountains stretching from Pikes Peak in the south to Longs Peak in the north — as you descend across the flat plains toward the airport. Notable sights include: Front Range of the Rocky Mountains (Pikes Peak, Mount Evans, Longs Peak), Denver city skyline, South Platte River valley, Denver International Airport's white tensile roof structure.

The flight from Port Columbus International (CMH) to Denver International (DEN) takes Approximately 3 hours 15 minutes to 3 hours 45 minutes.

The flight tracks nearly due west across Indiana, Illinois, and Missouri before crossing into Kansas. Notable features include the Mississippi River crossing near St. Louis (visible as a wide brown ribbon with the Gateway Arch faintly visible from altitude), the flat agricultural checkerboard of central Kansas, the Republican and Smoky Hill River valleys cutting across western Kansas, and the gradual color shift from green Midwest farmland to the tan shortgrass prairie of eastern Colorado as you approach the Rockies.
