The left side wins on both ends of the flight: a scenic left-turning departure over Washington D.C.'s monuments and river, and a descent into Seattle that keeps Mount Rainier and the Cascades in view before landing. The right side mostly offers flat Midwestern plains during cruise with no comparable bookend views.
