Sit on the Left side of the plane for the best views on flights from Boston to Frankfurt. Left side wins both ends of the flight. Over the Atlantic mid-flight there is little to distinguish sides, but the left seat delivers Boston's harbor and skyline on departure and Frankfurt's city center and the Taunus on approach, making it the clear choice for the whole journey.

During takeoff from General Edward Lawrence Logan International (BOS), sit on the Left side for the best views. Logan's most common eastward departures on Runway 33L/33R or 22L head northeast over the harbor then curve north. A left seat gives you Boston Harbor, the downtown skyline, and the Charles River basin as you climb out. Right seat faces the open Atlantic with little to see. Notable sights include: Boston Harbor islands, downtown Boston skyline with the Prudential and Hancock towers, Charles River and Cambridge, Cape Ann coastline to the north.

When landing at Frankfurt Main (FRA), sit on the Left side for the best views. Frankfurt typically uses westward landings on Runway 25L/25R, meaning the approach comes from the east over the Rhine-Main region. Left side gives you the Frankfurt skyline (Bankenviertel), the Main River, and the Taunus hills to the north. Right side faces south toward flat farmland. Notable sights include: Frankfurt Bankenviertel skyscrapers, Main River curving through the city, Taunus hills to the north, Sachsenhausen district south of the Main.
