Sit on the Left side of the plane for the best views on flights from Barcelona to Toronto. Left side wins both ends of the flight. At takeoff you get Barcelona's iconic urban layout and the Mediterranean coast, and on arrival you get the Toronto skyline and Lake Ontario. The transatlantic cruise at 35,000 feet over open ocean and Newfoundland/Labrador offers little window-seat advantage on either side.

During takeoff from Barcelona (BCN), sit on the Left side for the best views. Barcelona El Prat typically departs on runway 07R heading northeast, then turns northwest toward the Atlantic. The left side gives you the city of Barcelona, the Gothic Quarter grid, and the Sagrada Familia visible as you climb over the urban core. The Collserola ridge and Tibidabo hill are clearly identifiable just inland. Notable sights include: Barcelona city grid and port, Tibidabo hill and Collserola ridge, Montjuïc promontory, Mediterranean coastline curving toward the Ebro delta.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. Pearson typically lands on runway 06L/06R or 23 depending on wind. On the common westerly approach from the east, the left side tracks over Lake Ontario and gives you the Toronto skyline, CN Tower, and the lake's north shore. The right side sees suburban sprawl with little of interest. Notable sights include: CN Tower and Toronto downtown skyline, Lake Ontario shoreline, Toronto Islands, Mississauga suburban grid approaching the airport.

The flight from Barcelona (BCN) to Lester B Pearson International (YYZ) takes Approximately 9 to 9.5 hours.

The flight tracks northwest over the Pyrenees and Bay of Biscay, crosses the Atlantic at high latitude passing south of Greenland and Iceland's influence zone, crosses Newfoundland's rugged interior and the Gulf of St. Lawrence, then tracks southwest over Quebec and Ontario toward Toronto. The Newfoundland coastline and St. Lawrence River mouth are the most visually distinctive geographic features during the descent phase.
