Sit on the Right side of the plane for the best views on flights from Hanoi to Buenos Aires. Takeoff views from the right are significantly more dramatic (Truong Son Mountains and Red River Delta), while landing views favor the left (Río de la Plata and Buenos Aires). The takeoff advantage outweighs the landing disadvantage for overall journey interest.

During takeoff from Noibai International (HAN), sit on the Right side for the best views. Noibai typically departs northbound (Runway 01L/01R). Right-side seats face west across the Red River Delta toward the Truong Son Range. Left seats look east over the Gulf of Tonkin with less dramatic terrain. Notable sights include: Red River Delta (immediate foreground, patchwork of rice paddies and waterways), Truong Son Mountains (western horizon, spine of northern Vietnam), Gulf of Tonkin (eastern edge, visible as water body), Hanoi urban sprawl (directly below transitioning to rural delta).

When landing at Ezeiza Ministro Pistarini (EZE), sit on the Left side for the best views. Ezeiza typically lands from the east (Runway 09). Left-side seats face south across the Río de la Plata estuary and the Buenos Aires metropolitan area. Right seats look north over the flat pampas with less visual interest during final approach. Notable sights include: Río de la Plata estuary (wide, muddy-brown waterway dominating the view), Buenos Aires urban grid (extensive city sprawl with distinctive street patterns), Acoyte neighborhood and southern suburbs (immediate approach area), Pampas grassland (extending south and west, flat horizon).

The flight from Noibai International (HAN) to Ezeiza Ministro Pistarini (EZE) takes Approximately 19-20 hours (including typical routing via Middle East or Africa).

Flight path crosses the Indian Ocean (featureless water for 8-10 hours), passes over the Arabian Peninsula or East Africa depending on routing, then crosses central Africa (Sahara or sub-Saharan savanna depending on exact track), before reaching the South Atlantic. The Andes Mountains are visible during descent into Buenos Aires if approaching from the west, though most transoceanic routing approaches from the northeast.
