Sit on the Right side of the plane for the best views on flights from Montreal to Porto. While takeoff favors the left, the landing approach on the right side provides more dramatic and memorable scenery—the Douro estuary and Porto's historic hillside architecture are far more visually distinctive than the relatively flat terrain on approach from the left.

During takeoff from Montreal International Dorval (YUL), sit on the Left side for the best views. Left side offers views of the St. Lawrence River valley and the Laurentian Mountains as the aircraft climbs northeastward out of Montreal. Right side faces inland toward less distinctive terrain. Notable sights include: St. Lawrence River, Laurentian Mountains (Chaîne des Laurentides), Montreal urban sprawl, Île-Perrot.

When landing at Porto (OPO), sit on the Right side for the best views. Right side provides excellent views of the Douro River estuary, the Atlantic coastline, and Porto's distinctive hillside architecture as the aircraft descends toward OPO from the northeast. The city sits on steep terrain overlooking the river mouth, making it visually striking from the right side during approach. Notable sights include: Douro River estuary, Atlantic Ocean, Porto's historic Ribeira district on hillsides, Serra da Arrabida (distant southern hills).

The flight from Montreal International Dorval (YUL) to Porto (OPO) takes Approximately 6.5 to 7 hours.

The flight path crosses the Atlantic Ocean for roughly 5 hours. Notable features include: the Newfoundland and Labrador coastline (if visible during early stages), the open Atlantic with occasional shipping lanes, the Irish coast and Celtic Sea (approaching European airspace), and the Bay of Biscay. The aircraft typically follows a great-circle route, passing well north of the Azores. Over the Atlantic, there are few visible landmarks except occasional cloud formations and the curvature of the ocean horizon. As the flight approaches Portugal, the Iberian Peninsula becomes visible, with the Portuguese coastline and interior plateau gradually appearing on the horizon before descent toward Porto.
