Sit on the Right side of the plane for the best views on flights from Seattle to Frankfurt. Right-side seats win overall due to superior views during the critical takeoff phase with Mount Rainier and the Cascades. While the landing favors the left, the extended transatlantic cruise offers minimal scenic value regardless of side, making the dramatic Seattle departure the deciding factor.

During takeoff from Boeing Fld King Co International (BFI), sit on the Right side for the best views.

Notable sights include: Mount Rainier (14,410 ft, ~50 miles southeast), Cascade Range peaks, Lake Washington, Puget Sound shoreline.

When landing at Frankfurt Main (FRA), sit on the Left side for the best views. Left-side seats provide views of the Rhine River valley, the Main River, and Frankfurt's skyline during the descent approach from the northwest. Aircraft typically approach Frankfurt from the west or northwest, making the left side optimal for viewing the river systems and city landmarks. Notable sights include: Rhine River, Main River, Frankfurt skyline and financial district, Taunus hills to the north.
