Sit on the Left side of the plane for the best views on flights from New Orleans to Denver. Left side wins both ends of the flight. At takeoff you get Lake Pontchartrain and the Mississippi River crescent, and on arrival you get the full panoramic broadside view of the Rocky Mountain Front Range. The right side offers flat plains for most of the flight and faces away from the mountains on approach.

During takeoff from Louis Armstrong New Orleans International (MSY), sit on the Left side for the best views. MSY's primary departure runway 20 sends aircraft southwest before turning northwest toward Denver. A left-side seat gives you a clear view back over Lake Pontchartrain to the north and the Mississippi River's distinctive bends through New Orleans. The city grid and French Quarter waterfront are visible on the left as the aircraft banks northwest. Notable sights include: Lake Pontchartrain (massive lake immediately north of the city), Mississippi River crescent bend through downtown New Orleans, New Orleans city grid and CBD, Lake Borgne to the east.

When landing at Denver International (DEN), sit on the Left side for the best views. DEN's primary arrival from the southeast typically uses runways 34L/34R or 35L/35R, bringing aircraft in from the south-southeast on a northward heading. A left-side seat faces west, giving you a direct broadside view of the entire Front Range of the Rocky Mountains — from Pikes Peak in the south to Longs Peak in the north — as you descend over the plains. The right side faces east toward the flat Kansas/Colorado plains with little of interest. Notable sights include: Front Range of the Rocky Mountains (Pikes Peak, Mount Evans, Longs Peak visible as a continuous wall), Denver city skyline in the middle distance, Chatfield Reservoir south of Denver, the flat checkerboard agricultural plains of the Denver metro area.

The flight from Louis Armstrong New Orleans International (MSY) to Denver International (DEN) takes Approximately 3 hours 15 minutes.

The flight crosses the Arkansas River valley in central Arkansas, then the flat Oklahoma plains, followed by the Texas Panhandle's Llano Estacado plateau. Over eastern Colorado the terrain gradually rises from 3,000 to 5,000 feet as the high plains approach the Rockies. The Canadian River and Cimarron River valleys are faintly visible as shallow erosion cuts across the Oklahoma and Texas panhandle landscape.
