Sit on the Left side of the plane for the best views on flights from Rome to Toronto. Left side wins at both ends of the flight. Departure gives you Rome and the Alban Hills crater lakes; arrival gives you Lake Ontario and the Toronto skyline with the CN Tower. Over the Atlantic the views are largely featureless ocean on both sides, so the terminal phases decide it.

During takeoff from Ciampino (CIA), sit on the Left side for the best views. Ciampino's primary departure runway 15 sends the aircraft southeast before turning northwest toward the Atlantic. A left seat gives you a clear view back over central Rome including the Tiber River bends, the Colosseum area, and the Vatican dome as the aircraft climbs and banks. The Alban Hills volcanic complex sits immediately to the southeast and is visible on the left during initial climb. Notable sights include: Alban Hills (Castelli Romani volcanic crater lakes), Tiber River snaking through Rome, Vatican City and St. Peter's dome, Lake Albano crater lake.

When landing at Lester B Pearson International (YYZ), sit on the Left side for the best views. Pearson's primary arrival runway 06L/24R and 05/23 configurations typically bring transatlantic flights in from the east or northeast. A left seat on approach from the east gives views over Lake Ontario's northern shoreline, the Toronto downtown skyline including the CN Tower, and the grid of the city spreading north. The right side faces largely suburban sprawl toward Mississauga. Notable sights include: Lake Ontario northern shoreline, Toronto downtown skyline with CN Tower, Humber River valley, Highway 401 corridor.

The flight from Ciampino (CIA) to Lester B Pearson International (YYZ) takes Approximately 9 to 10 hours.

After departing Rome the route typically tracks northwest over Tuscany and the Ligurian coast, then crosses the French Alps or southern France before reaching the Atlantic near the Bay of Biscay. The transatlantic crossing passes south of Iceland and Greenland's southern tip, which may be visible as ice-covered terrain on the left side at cruise altitude in clear conditions. The route then crosses Newfoundland and the Gulf of St. Lawrence, where the St. Lawrence River estuary and the Canadian Shield's lake-dotted boreal forest become visible during descent.
