Sit on the Left side of the plane for the best views on flights from Delhi to Zurich. While the right side wins at Delhi departure, the left side dominates the majority of the flight — it faces south over Afghanistan and Iran giving views of the Zagros Mountains and Persian highlands, then the Turkish plateau, and delivers the spectacular Alpine approach into Zurich. The Alpine panorama on landing alone makes left the better overall choice.

During takeoff from Indira Gandhi International (DEL), sit on the Right side for the best views. IGI Airport typically departs westward or northwestward on runways 28/29, so the right side faces north toward Old Delhi, the Yamuna River, and the dense urban sprawl of central Delhi. You get a clear view of the city grid and the river bending through it as you climb out. Notable sights include: Yamuna River bend through Delhi, Old Delhi's dense urban core, Connaught Place area grid, Indira Gandhi Canal to the north.

When landing at Zurich (ZRH), sit on the Left side for the best views. Zurich typically lands on runway 14 or 16 from the northeast, or runway 28 from the east. On the common easterly approach over the Swiss Plateau, the left side faces south toward the Alps — you get a panoramic view of the Bernese and Glarus Alps, Lake Zurich, and the city itself on final approach. Notable sights include: Lake Zurich stretching southeast, Swiss Alps panorama to the south (Glarus Alps, Bernese Alps on the horizon), Zurich city center and Limmat River, Lake Greifen to the east.

The flight from Indira Gandhi International (DEL) to Zurich (ZRH) takes Approximately 8 to 9 hours.

The route crosses Pakistan's Punjab plains, then the Hindu Kush foothills near Kabul, the Iranian plateau and Zagros Mountain ranges, southeastern Turkey and the Anatolian plateau, then the Balkans and Austrian Alps before descending into Switzerland. The Zagros Mountains over Iran and the Turkish-Iranian border highlands are particularly dramatic from altitude on the left side.
