Sit on the Left side of the plane for the best views on flights from Denver to Dallas-fort Worth. The left side wins overall because the Rocky Mountain Front Range departure view is one of the most spectacular in US domestic aviation — a long wall of high peaks visible for the first 20-30 minutes of flight. The DFW arrival on the right is good but the Texas plains offer less drama. Left side gets the mountains on departure and still has a reasonable view of the metroplex on arrival.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN typically departs southbound or eastbound. On a southbound departure from runway 17L/17R, the left (east) side gives you the Denver metro grid and the plains, but on the more common eastbound then south routing, the left side picks up the Front Range and Rocky Mountains as the aircraft banks south. The Rocky Mountain Front Range — from Longs Peak down through Mount Evans and Pikes Peak — lines up beautifully on the left as you climb out heading southeast toward DFW. Notable sights include: Rocky Mountain Front Range (Longs Peak, Mount Evans, Pikes Peak), Denver metro grid and downtown skyline, Chatfield Reservoir south of Denver, Palmer Lake divide area.

When landing at Dallas Fort Worth International (DFW), sit on the Right side for the best views. DFW arrivals from the north typically use runways 17L/17R or 18L/18R, meaning the aircraft approaches from the north heading south. On this approach, the right (west) side gives you the best view of the DFW airport complex itself, Fort Worth city center to the west, and the sprawling Dallas-Fort Worth metroplex laid out across the flat Texas plains. The left side faces east toward open suburban sprawl with less visual interest. Notable sights include: Fort Worth downtown skyline, DFW airport complex and its distinctive oval terminal layout, Lake Grapevine to the northeast, Dallas skyline visible to the east on the horizon.

The flight from Denver International (DEN) to Dallas Fort Worth International (DFW) takes Approximately 2 hours to 2 hours 20 minutes.

The flight crosses the Texas Panhandle and southern Oklahoma. Notable features include the Canadian River breaks and caprock escarpment of the Llano Estacado visible as subtle terrain changes in the otherwise flat high plains, the Red River valley marking the Texas-Oklahoma border, and the gradual transition from shortgrass prairie to the more developed Cross Timbers region of north Texas as you descend toward DFW.
