Sit on the Left side of the plane for the best views on flights from Philadelphia to Portland. The left side wins on both ends: a skyline view of Philadelphia at takeoff and a striking view of Mount Hood and the Columbia River Gorge on approach into Portland, giving it far more visual variety than the right side's flatter, less distinctive scenery.

During takeoff from Philadelphia International (PHL), sit on the Left side for the best views. Departing PHL westbound, the left side offers a good look back at Philadelphia's skyline along the Delaware and Schuylkill rivers before the route turns toward the interior. It's a brief but distinct urban view compared to the flat suburban sprawl on the right. Notable sights include: Philadelphia skyline (Center City skyscrapers), Schuylkill River, Delaware River, Camden waterfront.

When landing at Portland International (PDX), sit on the Left side for the best views. On approach into PDX from the east or south, the left side typically reveals Mount Hood's snow-capped volcanic cone and the Columbia River Gorge, both dramatic and unmistakable landmarks. The right side mostly shows flat Willamette Valley farmland with less visual interest. Notable sights include: Mount Hood, Columbia River, Willamette River, Portland downtown skyline.

The flight from Philadelphia International (PHL) to Portland International (PDX) takes 5h 45m.

The route crosses the Appalachian Mountains (Allegheny ridges), the flat farmland of the Midwest, the Missouri River valley, and the Rocky Mountains before descending toward the Columbia River basin and the Cascade Range.
