Sit on the Left side of the plane for the best views on flights from Portland to Dallas-fort Worth. The left side delivers the most dramatic scenery of the flight during departure — the Columbia River, Portland, and Mount Hood are genuinely spectacular. Mid-flight over Oregon and Nevada the views are comparable on both sides, but the left side also tracks closer to the Cascade and Sierra Nevada ranges in the distance during the early portion of the route. The landing advantage on the right is real but modest compared to the takeoff payoff on the left.

During takeoff from Portland International (PDX), sit on the Left side for the best views. PDX typically departs south on runway 28L/R heading west then turning south, or uses runway 10L/R heading east. On a southbound departure toward DFW, the left side gives you the Columbia River immediately below, then Mount Hood to the southeast and the Portland metro grid. The right side faces north toward Washington state with less dramatic terrain. Notable sights include: Columbia River, Mount Hood, Portland city grid, Willamette River confluence.

When landing at Dallas Fort Worth International (DFW), sit on the Right side for the best views. DFW typically lands from the east on runways 17C/17L/17R heading south, or from the north heading south. On approach from the north-northwest, the right side faces west toward Fort Worth and gives a clear view of the DFW metroplex sprawl, the Trinity River corridor, and downtown Fort Worth's skyline. The left side faces east toward Dallas proper but is often blocked by the fuselage angle on final. Notable sights include: Fort Worth downtown skyline, DFW airport layout, Trinity River, Lake Grapevine.

The flight from Portland International (PDX) to Dallas Fort Worth International (DFW) takes Approximately 3 hours 15 minutes to 3 hours 45 minutes.

The route crosses southern Oregon's high desert plateau, then the Basin and Range terrain of northern Nevada and Utah's edge, followed by the flat scrubland of the Texas Panhandle and North Texas. The Cascade Range is visible to the west shortly after departure. Over Nevada and Utah, the terrain is arid basin-and-range with dry lake beds occasionally visible. The Texas Panhandle is almost entirely flat agricultural land with center-pivot irrigation circles visible from altitude.
