Sit on the Left side of the plane for the best views on flights from Taipei to Calcutta. While takeoff favors the right for Taiwan Strait views, the landing approach to Calcutta provides more dramatic and sustained visual interest with the Hooghly River's oxbow meanders and Sundarbans delta—distinctive geographic features that dominate the final 30 minutes of flight. Left seats capture these better during standard easterly approaches.

During takeoff from Chiang Kai Shek International (TPE), sit on the Right side for the best views. TPE typically departs runway 05L/05R (northeast heading). Right-side seats face the Taiwan Strait and northern Taiwan's coastline during initial climb, with clear views of the Taipei Basin and coastal geography before heading west toward the Asian mainland. Notable sights include: Taiwan Strait (immediate right), Taipei Basin urban sprawl, northern Taiwan coastline, Yangmingshan volcanic plateau to the northwest.

When landing at Netaji Subhash Chandra Bose International (CCU), sit on the Left side for the best views. CCU uses runways 10/28 depending on wind. For typical easterly approaches (runway 10), left-side seats provide views of the Hooghly River's dramatic meanders, the Sundarbans mangrove delta to the south, and Calcutta's urban sprawl. The river's oxbow bends are particularly distinctive from altitude. Notable sights include: Hooghly River with characteristic oxbow meanders, Sundarbans mangrove delta (south), Calcutta urban area, Howrah Bridge area.

The flight from Chiang Kai Shek International (TPE) to Netaji Subhash Chandra Bose International (CCU) takes Approximately 4 hours 45 minutes to 5 hours 15 minutes.

The flight path crosses the Bay of Bengal heading west-southwest. Notable features include the Irrawaddy Delta (Myanmar) visible around the 2-hour mark if flying slightly north of direct track, the Andaman Sea's open waters dominating the mid-flight period, and the Sundarbans mangrove delta appearing approximately 30-45 minutes before landing. The Arakan Mountains (Myanmar-Bangladesh border) may be visible as a distant ridge on the northern horizon during the middle portion of the flight, depending on exact routing and visibility.
