Sit on the Left side of the plane for the best views on flights from Buffalo to Denver. Left side wins both ends of the flight. At takeoff you get Lake Erie and the Niagara River, and on approach into Denver the left side delivers the full panoramic view of the Front Range for 20-30 minutes of descent. The right side sees mostly flat Great Plains terrain throughout.

During takeoff from Buffalo Niagara International (BUF), sit on the Left side for the best views. Buffalo Niagara typically departs westward on runway 23 or southward on runway 14, and a left-side seat gives you a clear view back toward Lake Erie and the Niagara River corridor as you climb out. You can track the river south toward the gorge and see the urban grid of Buffalo below before turning west. Notable sights include: Lake Erie shoreline, Niagara River corridor, Buffalo downtown grid, Grand Island.

When landing at Denver International (DEN), sit on the Left side for the best views. Denver International sits northeast of downtown Denver, and aircraft typically approach from the east on runway 16L/R or from the northeast on runway 25. A left-side seat on approach from the east gives you a sustained, unobstructed view of the entire Front Range — from Longs Peak in the north down through the Denver foothills — as the Rockies form a dramatic wall along the western horizon during descent. Notable sights include: Front Range of the Rocky Mountains, Longs Peak, Mount Evans, Denver downtown skyline.

The flight from Buffalo Niagara International (BUF) to Denver International (DEN) takes Approximately 3 hours 30 minutes.

The route crosses southern Lake Erie briefly, then tracks over northern Ohio and Indiana farmland, across Illinois and the Chicago metro area to the south, then over Iowa and Nebraska cornbelt. Western Nebraska brings the first subtle terrain changes with the Sandhills. Eastern Colorado is flat High Plains until the Front Range suddenly appears on the horizon roughly 80 miles out from Denver.
