Sit on the Right side of the plane for the best views on flights from Sao Paulo to Montreal. While takeoff offers mountain scenery, the landing approach over the St. Lawrence River and Laurentian Mountains provides more dramatic and sustained visual interest. The river crossing is a signature geographic feature of the Montreal approach that outweighs the initial climb-out views.

During takeoff from Congonhas (CGH), sit on the Left side for the best views. Left side offers views of the Serra da Mantiqueira mountain range and the Paraíba River valley as the aircraft climbs westward out of São Paulo. Right side faces the urban sprawl of greater São Paulo with limited scenic distinction. Notable sights include: Serra da Mantiqueira (distant peaks to the northwest), Paraíba River valley, Atlantic coastal escarpment, São Paulo metropolitan area receding below.

When landing at St Hubert (YHU), sit on the Right side for the best views. Right side provides views of the St. Lawrence River, the Laurentian Mountains, and the approach over the Ottawa River valley during descent into Montreal. Left side faces inland terrain with less distinctive features during the final approach. Notable sights include: St. Lawrence River (broad and prominent), Laurentian Mountains (northern ridge), Ottawa River valley, Montreal urban area and surrounding lowlands.

The flight from Congonhas (CGH) to St Hubert (YHU) takes 9h 15m.

The flight path crosses the Appalachian Mountains in eastern North America (visible as a series of ridges and valleys during the mid-flight cruise phase), the Great Lakes region (Lake Ontario and Lake Erie visible during descent into eastern Canada), and the transition from tropical/subtropical Brazilian highlands through temperate North American forests. The Atlantic seaboard and major river valleys (Hudson, Delaware, Susquehanna) may be visible during the approach phase depending on exact routing.
