Sit on the Left side of the plane for the best views on flights from Montreal to Sao Paulo. While takeoff offers better scenery, the landing approach over São Paulo's dramatic geography and the Serra da Cantareira provides the more memorable final hour. Left seats capture both the urban-to-mountain transition and the mountain backdrop on approach.

During takeoff from Montreal International Dorval (YUL), sit on the Right side for the best views. Dorval typically departs eastbound (Runways 06L/06R). Right-side seats face north across the Ottawa River valley and toward the Laurentian Mountains, offering immediate terrain contrast. Left side shows the flat St. Lawrence lowlands extending toward Vermont. Notable sights include: Ottawa River (immediate north), Laurentian Mountains (northern horizon, 30+ miles distant), Lake of Two Mountains (northwest, visible as water body), St. Lawrence River valley (south, receding).

When landing at Guarulhos (GRU), sit on the Left side for the best views. Guarulhos typically lands westbound (Runways 27L/27R). Left-side seats on approach face south-southwest toward the Serra da Cantareira mountains and the broader São Paulo metropolitan basin. Right side shows the industrial northern suburbs and approaches from less scenic angles. Notable sights include: Serra da Cantareira (southern/southwestern horizon, 20+ miles distant), Paraíba River valley (visible as linear feature), São Paulo urban sprawl (immediate surroundings), Atlantic Plateau escarpment (southern distant ridge).

The flight from Montreal International Dorval (YUL) to Guarulhos (GRU) takes Approximately 9.5 to 10.5 hours.

The flight crosses the Atlantic at roughly 35,000 feet, passing over open ocean with no visible landmarks for approximately 6-7 hours. The route tracks southeast from Montreal across the North Atlantic, then south-southwest toward Brazil. Approaching South America, the Amazon Basin becomes visible as vast, unbroken green forest canopy (around 8.5 hours into flight). The Brazilian Highlands (Serra Geral) appear as elevated terrain with subtle topographic variation. The final approach descends over the interior plateau before reaching the São Paulo basin.
