Sit on the Left side of the plane for the best views on flights from Seattle to Firenze. The left side delivers the more dramatic single moment of the flight — Mount Rainier and the Seattle skyline on departure are genuinely spectacular.

Notable sights include: Florence Cathedral (Duomo) and its dome, Arno River, Tuscan hills (Chianti and Apennine foothills), Ponte Vecchio area.
