Sit on the Left side of the plane for the best views on flights from Dehra Dun to Delhi. While takeoff favors the right for Himalayan views, the landing approach provides superior geography—the Yamuna River, Delhi Ridge, and city structure are more visually distinctive and sustained than the brief Doon Valley departure. Left seats capture the most geographically significant portion of the flight.

During takeoff from Dehradun (DED), sit on the Right side for the best views. Dehradun airport (VIDN) typically departs northwestbound. Right-side seats face the Himalayan foothills and the Doon Valley's northern rim, where the Mussoorie range rises distinctly. Left side shows the valley floor and southern plains with less dramatic relief. Notable sights include: Mussoorie Ridge (northern escarpment of Doon Valley), Himalayan foothills receding northward, Rispana River valley, forested slopes of the lower Himalayas.

When landing at Indira Gandhi International (DEL), sit on the Left side for the best views. Approach to Delhi typically uses runways 27L/27R (westerly) or 28L/28R (northwesterly). Left-side seats on descent from the north provide clear views of the Yamuna River's course through Delhi, the ridge system (Aravalli foothills), and the city's northern expansion toward Noida. Right side faces the western plains with less distinctive features. Notable sights include: Yamuna River (meandering through Delhi), Aravalli Ridge (Delhi Ridge system running north-south), Noida urban sprawl (eastern bank), Delhi cantonment and central city districts.

The flight from Dehradun (DED) to Indira Gandhi International (DEL) takes Approximately 55-65 minutes.

The flight path (roughly 130 km southwest) crosses the transition zone between the Himalayan foothills and the Indo-Gangetic Plain. Notable features include: the Ganges River valley to the west (visible as a linear depression), the gradual lowering of terrain from ~2,000 feet in the Doon Valley to ~700 feet at Delhi, scattered towns along the NH-119 corridor (Roorkee, Meerut region), and the progressive flattening of the landscape as the aircraft descends toward the plains. The Aravalli Ridge system becomes visible on the right (east) side during descent, running north-south as a subtle but persistent elevation feature.
