Sit on the Left side of the plane for the best views on flights from Calcutta to Paro. While takeoff offers the Sundarbans delta, the landing approach into Paro provides the more dramatic and sustained views—the Phobjikha Valley, the Dochula escarpment, and the eastern Himalayan peaks create a far more visually distinctive finale than the relatively flat delta landscape at departure.

During takeoff from Netaji Subhash Chandra Bose International (CCU), sit on the Right side for the best views. CCU typically departs eastbound on Runway 01 or 03. Right-side seats face north and northeast, directly toward the Ganges River delta and the Sundarbans wetlands. Left seats look inland over the city and industrial areas with minimal geographic interest. Notable sights include: Hooghly River (immediately below during climb), Sundarbans mangrove delta (northeast, expanding toward horizon), Bay of Bengal (distant eastern horizon), Kolkata urban sprawl (western side, receding).

When landing at Paro (PBH), sit on the Left side for the best views. PBH approaches from the west on Runway 15 (southbound descent). Left-side seats face west and southwest during final approach, offering direct views of the Phobjikha Valley, the dramatic eastern Himalayas, and the Dochula Pass ridge system. Right seats face the opposite direction with minimal scenic value. Notable sights include: Eastern Himalayan peaks (Jomolhari massif region on horizon), Phobjikha Valley (broad, flat valley floor below), Dochula Pass ridge (prominent escarpment), Paro Chu river valley (narrow gorge leading to airport).

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

The flight path crosses from the Ganges delta northwestward across Bangladesh and into Bhutan. Notable midpoint features include the Brahmaputra River valley (visible around 30 minutes into flight, appearing as a broad, braided river system with multiple channels), the foothills of the Assam-Meghalaya plateau (rolling terrain with scattered settlements), and the transition into the higher Himalayan foothills as the aircraft climbs toward Paro's 7,000-foot elevation. The Bhutan border region shows a dramatic shift from flat agricultural plains to steep, forested mountainous terrain.
