Sit on the Left side of the plane for the best views on flights from New York to Denver. Left side wins both ends of the flight. During the cruise over Pennsylvania, Ohio, Indiana, and Illinois the views are relatively flat and similar on both sides, but the left side picks up better angles on the Great Lakes shoreline near Chicago and the Missouri River valley before the dramatic Front Range arrival at Denver.

During takeoff from John F Kennedy International (JFK), sit on the Left side for the best views. JFK departures heading west typically use runways 31L/31R, banking left over Jamaica Bay and the Rockaway Peninsula. The left side gets a clear view of Lower Manhattan's skyline, the Verrazano-Narrows Bridge, and the Hudson River as the aircraft climbs and turns westward. Notable sights include: Lower Manhattan skyline, Verrazano-Narrows Bridge, Jamaica Bay, Hudson River.

When landing at Denver International (DEN), sit on the Left side for the best views. Denver approaches from the east on runways 34L/34R or 35L/35R, meaning the aircraft descends over the plains with the Front Range of the Rockies visible to the west. The left side faces south-southwest and gets a panoramic broadside view of the entire Front Range including Pikes Peak and the Denver metro spread below. Notable sights include: Front Range of the Rocky Mountains, Pikes Peak, Denver metro grid, Rocky Mountain Arsenal area.

The flight from John F Kennedy International (JFK) to Denver International (DEN) takes Approximately 4 hours 15 minutes.
