Sit on the Left side of the plane for the best views on flights from Houston to Denver. Left side wins both ends of the flight. At takeoff you get the Houston skyline and Ship Channel. En route the left side tracks westward and picks up the Texas Panhandle's Canadian River breaks and eventually the first views of the Rockies. The landing approach delivers the entire Front Range panorama on the left, which is genuinely one of the best arrival views in the continental US.

During takeoff from George Bush Intcntl Houston (IAH), sit on the Left side for the best views. IAH typically departs northwest on runways 26L/26R or north on 15R/33L. On a northwest departure toward Denver, the left (south) side looks back over downtown Houston's skyline and the Ship Channel industrial complex. The right side faces open suburban sprawl with little of interest. Notable sights include: Downtown Houston skyline, Houston Ship Channel and refineries, Lake Houston to the northeast, Hobby Airport in the distance to the south.

When landing at Denver International (DEN), sit on the Left side for the best views. DEN typically lands from the east on runways 34L/34R or 35L/35R, approaching from the plains. On approach from the south-southeast (coming from Houston), the left side faces west and has a continuous, unobstructed view of the entire Front Range of the Rocky Mountains — from Pikes Peak in the south to Longs Peak in the north — as the aircraft descends over the plains. The right side looks east over flat featureless Colorado prairie. Notable sights include: Front Range of the Rocky Mountains (Pikes Peak, Mount Evans, Longs Peak), Denver city skyline against the mountains, the flat Colorado High Plains, Cherry Creek Reservoir.

The flight from George Bush Intcntl Houston (IAH) to Denver International (DEN) takes Approximately 2 hours 45 minutes.

The flight crosses the flat Texas coastal plain, then the rolling Cross Timbers of north Texas, the Texas Panhandle with the Canadian River canyon system visible as a notable break in the flat terrain, the New Mexico-Colorado border region with the Raton Mesa and Comanche National Grassland, then the Colorado High Plains before the dramatic Front Range comes into view on descent. No significant water bodies. Terrain remains flat until the final 100 miles when the Rockies appear on the western horizon.
