Sit on the Left side of the plane for the best views on flights from Denver to Houston. The left side delivers the Rocky Mountain Front Range panorama on departure and Galveston Bay plus the NASA/Clear Lake area on arrival. The right side offers little beyond flat plains for most of the flight. Left wins both ends of the route.

During takeoff from Denver International (DEN), sit on the Left side for the best views. DEN's primary departure runways (16L/R heading south, or 35L/R heading north) mean the left side faces east toward the city and plains on southbound departures, but on the more common westbound climb-out after takeoff, the left side gets the Front Range of the Rockies. Departures toward Houston typically involve a southeasterly track, and as the aircraft banks right after liftoff, the left side faces northeast toward downtown Denver and the plains while the right side faces south. However, climbing out southeast, the left (north-facing) window captures the full panorama of the Rocky Mountain Front Range including Pikes Peak to the south and Longs Peak to the north spread across the horizon. Notable sights include: Rocky Mountain Front Range (Longs Peak to Pikes Peak), Denver city grid and downtown skyline, Chatfield Reservoir, Palmer Lake divide.

When landing at Ellington Fld (EFD), sit on the Left side for the best views. Ellington Field sits southeast of Houston, and approaches typically come in from the north or northwest on runway 17/35. On a northerly approach heading south, the left side faces east toward Galveston Bay and the Gulf of Mexico coastline, while the right side looks inland. The left window gives a clear view of the Houston Ship Channel, Clear Lake, and the broad expanse of Galveston Bay opening toward the Gulf. Notable sights include: Galveston Bay, Clear Lake and NASA Johnson Space Center campus, Houston Ship Channel industrial corridor, Galveston Island on the horizon.

The flight from Denver International (DEN) to Ellington Fld (EFD) takes Approximately 2 hours 15 minutes to 2 hours 30 minutes.

The flight crosses the Texas Panhandle's flat Llano Estacado plateau, the Canadian River breaks and caprock escarpment near Amarillo, then descends over the rolling Cross Timbers and post oak savanna of central Texas before reaching the flat Gulf Coastal Plain north of Houston. No significant water bodies or mountain terrain mid-route — largely featureless high plains transitioning to Texas prairie.
