Sit on the Right side of the plane for the best views on flights from Calcutta to New York. The right side wins overall because the Kolkata departure offers genuinely dramatic and rare views — the Hooghly River, Howrah Bridge, and the vast Bengal delta are spectacular and seldom seen by Western travelers. The JFK arrival on the left is excellent but Manhattan approaches are more commonly experienced. Right side also captures the Greenland ice sheet and Canadian Shield lakes during the polar routing.

During takeoff from Netaji Subhash Chandra Bose International (CCU), sit on the Right side for the best views. CCU's primary departure runway 19R sends aircraft heading roughly south before turning northwest, placing the Hooghly River and central Kolkata on the right side. You get a clear view of the river's distinctive bend through the city and the dense urban grid of north Kolkata. Notable sights include: Hooghly River bend through Kolkata, Howrah Bridge (visible as a steel cantilever span), Salt Lake City township grid to the northeast, Sundarbans mangrove delta beginning to the south.

When landing at John F Kennedy International (JFK), sit on the Left side for the best views. JFK's most common arrival paths from the east bring aircraft in over the Atlantic on runway 22L/31L approaches, with Manhattan's skyline visible to the left (north) as you cross the Jamaica Bay shoreline. The left side gives you the clearest view of Lower Manhattan, the Verrazano-Narrows Bridge, and the full sweep of New York Harbor. Notable sights include: Manhattan skyline (Lower Manhattan and Midtown towers visible simultaneously), Jamaica Bay and its barrier islands, Verrazano-Narrows Bridge, New York Harbor.

The flight from Netaji Subhash Chandra Bose International (CCU) to John F Kennedy International (JFK) takes Approximately 16 to 17 hours nonstop, typically operated via a polar or near-polar routing over Central Asia, Russia, and the North Atlantic.

The route typically tracks northwest over the Gangetic Plain, then over the Hindu Kush and Pamir ranges of Afghanistan and Tajikistan, across the vast Siberian taiga and river systems including the Ob and Yenisei, over the Arctic Ocean near the North Pole, then descending across the Greenland ice cap (visible as a featureless white plateau), the Davis Strait, Labrador, and the Canadian Maritime provinces before reaching the US Northeast coast
