Sit on the Right side of the plane for the best views on flights from Paris to Hanoi. While left offers good Paris departure views, right provides superior scenery for the majority of the flight and especially during the critical landing phase. The Red River Delta and approach to Hanoi are visually distinctive and geographically significant, making right the better overall choice.

During takeoff from Charles De Gaulle (CDG), sit on the Left side for the best views. Left side offers views of the Seine River winding through Paris and the surrounding Île-de-France region as you climb out. You'll see the city's urban sprawl and the flat agricultural plains extending northward toward the English Channel. Notable sights include: Seine River, Paris metropolitan area, Île-de-France plains, English Channel coastline (distant).

When landing at Noibai International (HAN), sit on the Right side for the best views. Right side provides excellent views during descent into Hanoi. You'll see the Red River Delta's intricate network of waterways, rice paddies, and the Tonkin Gulf coastline. The approach typically brings the right wing toward the delta's western edge, offering clear views of the river system and surrounding lowlands. Notable sights include: Red River Delta, Tonkin Gulf, Red River, Hanoi urban area.

The flight from Charles De Gaulle (CDG) to Noibai International (HAN) takes Approximately 11-12 hours.

The flight path crosses the Alps (visible from both sides during early climb, roughly 1-2 hours out), then proceeds southeast over the Mediterranean, Middle East, and South Asia. Notable midpoint features include the Adriatic Sea, Balkans, Black Sea region, Caucasus Mountains, Persian Gulf, Arabian Sea, and the Indian subcontinent. The Himalayas become visible on the left side during descent into Southeast Asia, roughly 1-2 hours before landing. The flight primarily follows a southeast corridor, so neither side dominates the entire route, but the landing approach heavily favors the right.
