Sit on the Left side of the plane for the best views on flights from Portland to Philadelphia. The left side wins on both ends: a dramatic volcanic mountain departure from Portland and a skyline river view landing into Philadelphia, while the right side offers mostly flat Midwest plains during cruise with little variation.

During takeoff from Portland International (PDX), sit on the Left side for the best views. Departing PDX eastbound, the left side gets a clear view of Mount Hood rising sharply above the Cascade foothills, along with Mount St. Helens and Mount Adams visible further north. This is one of the most distinctive volcanic landscapes visible from any US departure. Notable sights include: Mount Hood, Mount St. Helens, Mount Adams, Columbia River Gorge.

When landing at Philadelphia International (PHL), sit on the Left side for the best views. On approach into PHL from the west, the left side offers views over the Philadelphia skyline and the Delaware River waterfront before landing. Center City's skyscrapers and the river bridges are visible in the final minutes of descent. Notable sights include: Philadelphia skyline, Delaware River, Ben Franklin Bridge, Schuylkill River.

The flight from Portland International (PDX) to Philadelphia International (PHL) takes 5h 05m.
