Sit on the Right side of the plane for the best views on flights from Paro to Calcutta. Right side captures the dramatic Himalayan departure from Paro and offers better views of the high terrain during the initial climb. While the landing favors left, the takeoff scenery is more visually distinctive and memorable.

During takeoff from Paro (PBH), sit on the Right side for the best views. Paro Valley sits in a narrow gorge with the Phobjikha Valley and eastern Himalayan ridges visible to the right during climb-out. Left side faces the western valley wall with less dramatic relief. Notable sights include: Paro Chu river valley floor, eastern Bhutanese Himalayan peaks (8,000-10,000 ft ridgelines), Druk Chirwang monastery perched on ridge, forested slopes of Paro District.

When landing at Netaji Subhash Chandra Bose International (CCU), sit on the Left side for the best views. Descent into Calcutta from the north brings the Hooghly River estuary and Sundarbans mangrove delta into view on the left. The river's winding course and the city's sprawl are most dramatic from this approach angle. Notable sights include: Hooghly River with its distinctive meanders, Sundarbans mangrove wetlands (dark green patches), Calcutta urban sprawl and Howrah Bridge area, Ganges Delta agricultural fields.

The flight from Paro (PBH) to Netaji Subhash Chandra Bose International (CCU) takes Approximately 1 hour to 1 hour 15 minutes.

The flight path descends from Bhutan's eastern Himalayan ridges (9,000-11,000 ft) southward across the Assam plains. Notable features include the Brahmaputra River valley visible to the east (left side of aircraft), the transition from mountainous terrain to flat alluvial plains around 30 minutes into flight, scattered towns in Assam including areas near Guwahati region, and the gradual appearance of the Ganges Delta's agricultural grid as the aircraft descends toward Calcutta. The Brahmaputra itself may be visible as a wide, braided river system if weather permits, appearing as a silvery-brown ribbon cutting through the green plains.
