Sit on the Left side of the plane for the best views on flights from Delhi to Calcutta. While takeoff favors the right, the landing approach provides more dramatic and sustained views of the Hooghly River and Calcutta's historic riverfront—the most distinctive geographic feature of this route. The landing experience outweighs the takeoff advantage.

During takeoff from Indira Gandhi International (DEL), sit on the Right side for the best views. DEL typically departs runway 09L/09R (westbound) or 27L/27R (eastbound). Right-side seats offer views of the Yamuna River floodplain and the sprawling southern suburbs of Delhi during initial climb. Westbound departures (more common) provide the clearest view of the city's eastern expansion and the river's meanders. Notable sights include: Yamuna River (visible as a distinct silvery ribbon below), Delhi's southern urban sprawl extending toward Noida, Aravalli Hills as a distant hazy ridge to the south, Indira Gandhi International Airport complex itself receding below.

When landing at Netaji Subhash Chandra Bose International (CCU), sit on the Left side for the best views. CCU uses runways 10/28. Approach vectors typically come from the west or northwest. Left-side seats provide excellent views of the Hooghly River (Ganges distributary) and Calcutta's riverfront districts during descent. The river's distinctive curves and the city's colonial-era layout are clearly visible from 8,000-12,000 feet. Notable sights include: Hooghly River with its characteristic bends and ghats, Calcutta's dense urban core on the eastern bank, Howrah Bridge area (visible as a distinct crossing point), Salt Lake City (Bidhannagar) as a planned grid development to the northeast.

The flight from Indira Gandhi International (DEL) to Netaji Subhash Chandra Bose International (CCU) takes Approximately 2 hours 15 minutes.

The flight path crosses the Gangetic Plain from west to east. Notable features include the Ganges River itself (visible as a major waterway around the Varanasi region if slightly north of direct routing), scattered towns and agricultural fields across Bihar and Jharkhand, and the transition from the Indo-Gangetic Plain's flat terrain to slightly more undulating ground as you approach Bengal. The Damodar River valley may be visible to the south depending on exact routing. No major mountain ranges intersect this route—the Himalayas lie well to the north.
