Sit on the Left side of the plane for the best views on flights from Singapore to Calcutta. While the right side wins at takeoff for Singapore's skyline, the left side dominates the majority of the flight. Once airborne and tracking northwest, the left side faces southwest over the Andaman Sea, the Bay of Bengal coastline, and eventually the Hooghly delta approach into Kolkata. The Hooghly River and Howrah Bridge on landing are genuinely iconic and hard to beat.

During takeoff from Singapore Changi (SIN), sit on the Right side for the best views. Changi typically departs westward on runway 02L/20R or 02C/20C, meaning a westbound departure gives the right side views over the Singapore Strait and the city skyline including Marina Bay. The right side captures the dense urban core and the southern islands as the aircraft climbs out over the strait. Notable sights include: Marina Bay Sands and CBD skyline, Sentosa Island and the southern islands chain, Singapore Strait shipping lanes with heavy vessel traffic.

When landing at Netaji Subhash Chandra Bose International (CCU), sit on the Left side for the best views. Kolkata's Netaji Subhash Chandra Bose airport primarily uses runway 01L/19R, with arrivals often from the south heading north. On a northward approach, the left side looks west over the Hooghly River, which makes a dramatic bend through the city, and the Howrah Bridge is visible as a distinctive cantilever span. The right side faces east over flat agricultural Bengal with less visual interest. Notable sights include: Hooghly River and its sweeping bend through Kolkata, Howrah Bridge cantilever span, dense urban grid of central Kolkata and Howrah district.

The flight from Singapore Changi (SIN) to Netaji Subhash Chandra Bose International (CCU) takes Approximately 3 hours 15 minutes.

The flight tracks northwest across the Bay of Bengal, a largely featureless open ocean crossing at cruise altitude. The Andaman and Nicobar Islands may be visible far to the left early in the flight as low green specks on the horizon. The coast of Myanmar and Bangladesh comes into view as the aircraft descends, with the vast Ganges-Brahmaputra delta visible as a maze of brown river channels and green islands spreading across the horizon before Kolkata.
