The right side wins both ends of the flight: dramatic volcanic peaks of the Cascades on departure from Seattle and skyline views of Philadelphia along the Delaware River on arrival, while the left side mostly faces open plains and less distinctive terrain during these phases.
Flight Path
Rocky Mountain Front near Montana's Glacier country, the flat farmland of North Dakota and Minnesota, the Great Lakes region around Lake Michigan and Lake Erie, and the forested ridges of the Appalachian Plateau as the flight nears Pennsylvania.

Takeoff from SEA
RIGHTSEA departures to the east typically climb south from the airport before banking left onto an easterly heading, putting the Cascade volcanoes squarely on the right side of the aircraft. Mount Rainier's glaciated summit dominates the view, with Mount St. Helens and Mount Adams also visible to the south as the plane climbs toward cruise altitude.

Landing at PHL
RIGHTPHL arrivals generally land toward the west on runway 27, which brings the aircraft in from the east and slightly north of the airport. This puts the Philadelphia skyline and the Delaware River off the right side of the cabin during the final descent and approach turn.
