Sit on the Right side of the plane for the best views on flights from Seattle to Buenos Aires. Right side wins both ends of the flight. During the long overwater and overland cruise through Central America, the Andes corridor, and Patagonia, the right side also faces generally east toward the Andes as the route tracks south along the western side of South America, offering occasional Andean views during daylight hours.

During takeoff from Seattle Tacoma International (SEA), sit on the Right side for the best views. SEA's primary departure runways (16L/16R heading south, or 34L/34R heading north) mean a right-side seat gives you views east toward the Cascade Range and Mount Rainier. Rainier at 14,411 ft is unmistakable and dominates the eastern skyline during climb-out, especially on southbound departures banking right. Notable sights include: Mount Rainier (southeast), Lake Washington (east), downtown Seattle skyline (north), Puget Sound (west, briefly visible on left before banking).

When landing at Ezeiza Ministro Pistarini (EZE), sit on the Right side for the best views. EZE sits west of Buenos Aires, and aircraft typically approach from the east or northeast on runway 11/29. A right-side seat on approach gives views of the Rio de la Plata estuary and the Buenos Aires city grid spreading out to the east, with the wide brown estuary visible to the north. Notable sights include: Rio de la Plata estuary (north/northeast), Buenos Aires city grid (east), Parana Delta wetlands (north), suburban Buenos Aires sprawl (below on approach).

The flight from Seattle Tacoma International (SEA) to Ezeiza Ministro Pistarini (EZE) takes Approximately 13 to 14 hours.

The route typically tracks south along the Pacific coast through Central America, then crosses into South America near Colombia or Ecuador. The Andes cordillera runs parallel to the right side of the aircraft for much of the South American leg, with volcanic peaks visible in Ecuador and Peru during daylight. The Atacama Desert in northern Chile appears as a stark brown plateau. The route eventually crosses the Argentine pampas on descent into Buenos Aires. Much of the flight is overnight given departure times, so Andean views depend heavily on scheduling.
