Sit on the Left side of the plane for the best views on flights from Calcutta to Ho Chi Minh City. While takeoff offers river views, the landing descent over the Mekong Delta's intricate canal and paddy system is more visually distinctive and geographically dramatic. The delta's geometric water patterns and villages provide superior scenic value compared to Calcutta's flatter, more industrial surroundings.

During takeoff from Netaji Subhash Chandra Bose International (CCU), sit on the Right side for the best views. Right-side seats offer views of the Hooghly River winding through Calcutta's eastern suburbs and the flat Ganges Delta plain stretching southeastward. The left side faces inland toward the city's western industrial areas with less dramatic topography. Notable sights include: Hooghly River (meandering through the delta), Calcutta city grid and Howrah Bridge area, flat alluvial plains of the Ganges Delta, scattered water bodies and agricultural fields.

When landing at Tansonnhat International (SGN), sit on the Left side for the best views. Left-side seats provide excellent views of the Mekong Delta's intricate waterway network and rice paddies as the aircraft descends toward Ho Chi Minh City from the northwest. The right side faces the industrial outskirts with less scenic interest. Notable sights include: Mekong Delta's braided river channels and canals, extensive rice paddies in geometric patterns, Can Tho or Ben Tre provinces' water villages, Ho Chi Minh City's sprawling urban area on final approach.

The flight from Netaji Subhash Chandra Bose International (CCU) to Tansonnhat International (SGN) takes Approximately 2 hours 45 minutes to 3 hours 15 minutes.

The flight path crosses the Bay of Bengal and enters Vietnam's coast near the Mekong Delta. Notable features include: the open water of the Bay of Bengal (relatively featureless but expansive), the Vietnamese coastline near Ca Mau Peninsula or Kien Giang Province with mangrove forests and coastal waterways, and the transition into the Mekong Delta's river system as the aircraft descends toward Ho Chi Minh City. The midpoint offers little scenic interest—mostly open water—making the takeoff and landing segments the primary viewing opportunities.
