The left side wins overall due to the spectacular Boston Harbor and downtown approach on landing, which is one of the most visually rewarding urban arrivals in the US. The right side is better for takeoff, but the left side also captures the northern Rockies, Great Lakes shoreline, and the Hudson Valley during cruise, making it the stronger seat for the full journey.
