Sit on the Left side of the plane for the best views on flights from Houston to Portland. Left side wins both ends of the flight. During the cruise over the Pacific Northwest, the left side also tracks closer to the Cascades as the route curves northwest, giving occasional views of volcanic peaks including Mount Shasta and the Oregon Cascades on the approach phase.

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 15L/15R.

Right side faces open suburban sprawl with little of interest. Notable sights include: Houston downtown skyline, Houston Ship Channel and refineries, Lake Houston to the northeast, Buffalo Bayou corridor.

When landing at Portland International (PDX), sit on the Left side for the best views. PDX primarily lands from the east on runways 28L/28R, approaching over the Columbia River from the east. The left side faces south toward Mount Hood dominating the horizon and the city of Portland below, while the right side looks north into Washington state with less dramatic scenery. Notable sights include: Mount Hood to the southeast, Portland city grid and Willamette River, Columbia River directly below on approach, Mount St. Helens on the distant northern horizon.

The flight from George Bush Intcntl Houston (IAH) to Portland International (PDX) takes Approximately 4 hours 15 minutes.

The route tracks northwest from Houston across eastern Texas, then over New Mexico and Arizona high desert, crossing the Colorado Plateau with its canyon systems visible at altitude, then over Nevada's Basin and Range terrain, before entering Oregon and the Cascade Range corridor on descent into Portland. Mount Shasta in northern California is a notable landmark on the left side during descent.
