Sit on the Right side of the plane for the best views on flights from Portland to Buenos Aires. While left seats excel during PDX departure for Cascade views, the landing at EZE strongly favors right seats for the dramatic Río de la Plata estuary approach and extended views of Buenos Aires' southern approach corridor. The landing experience outweighs the takeoff advantage.

During takeoff from Portland International (PDX), sit on the Left side for the best views. PDX typically departs runways 10L/10R (northwesterly) or 28L/28R (southeasterly). Left seats on northwest departures capture the Cascade Range immediately, with Mount Hood dominating the eastern horizon. On southeast departures, left seats still offer better views of the Willamette Valley's urban sprawl and the volcanic peaks beyond. Notable sights include: Mount Hood (11,240 ft, ~50 miles east), Cascade Range spine, Willamette River valley floor, Portland metro area grid.

When landing at Ezeiza Ministro Pistarini (EZE), sit on the Right side for the best views. Approaching EZE typically uses runways 09 (westerly) or 27 (easterly). Right seats on easterly approaches descend over the Río de la Plata estuary and the southern Buenos Aires suburbs, offering extended views of the massive river delta and the city's sprawl. Westerly approaches also favor right seats for viewing the estuary and approach corridor. Notable sights include: Río de la Plata estuary (massive muddy-brown water body), Buenos Aires southern suburbs and industrial zones, Aeroparque Jorge Newbery (smaller airport visible on approach), Ezeiza International Airport runway complex.

The flight from Portland International (PDX) to Ezeiza Ministro Pistarini (EZE) takes Approximately 10.5 to 11.5 hours.

This southeasterly route crosses the continental United States (Great Plains, Mississippi River valley visible on clear days), then the Gulf of Mexico or Atlantic approaches depending on routing. Over South America, the flight passes over the Amazon Basin (green canopy, river systems), then descends toward the Paraná River system and the Pampas grasslands before reaching Buenos Aires. The Andes Mountains are typically too far west of this routing to be visible, but the transition from tropical forest to temperate grassland is geographically significant.
