The right side scores higher due to Barcelona's exceptional landing approach over the Mediterranean and Montserrat mountains, which provides dramatic terrain variety and recognizable urban landmarks. While St. Louis offers a decent takeoff view of the Gateway Arch and Mississippi River, the majority of the transatlantic flight is open ocean on both sides (5+ hours), which limits both sides significantly. The right side's landing sequence compensates with genuine scenic drama that the left side's flat Midwest departure cannot match.
