Chicago to Malargue is 5,477 miles (8,814 km), a flight of about 10 hours.
While left offers good Chicago departure views, right dominates the flight's most dramatic scenery—the Andes Mountains during the long southern approach occupy nearly half the flight duration and provide unmatched visual impact.
Flight Path
The flight path crosses the Gulf of Mexico (visible as open water with scattered clouds), then passes over the Yucatan Peninsula and Central America. Over South America, the Amazon Basin appears as dense green forest canopy with river systems visible as dark linear features. The flight then transitions to the Brazilian Plateau and eventually the Andes foothills. The most notable midpoint feature is the Amazon River system—visible as a massive dendritic network of waterways around 6,000-8,000 feet altitude. Secondary features include the Andes cordillera becoming progressively more prominent as the aircraft descends toward Argentina, with the transition from tropical to arid landscape clearly visible. The Paraná River basin may be visible depending on exact routing. Right side seats will see the Andes increasingly dominate from roughly 3-4 hours before landing.
