Sit on the Left side of the plane for the best views on flights from Paris to Bangkok. Left side wins both the departure over Paris and the arrival over Bangkok's river delta. During the cruise, the flight tracks southeast over the Alps, then across the Caspian Sea, Iran, and the Bay of Bengal — the left side faces northeast for much of the route, offering views over the Himalayas from a distance during the India segment, while the right side looks into the Indian Ocean. Left is the stronger choice for the full journey.

During takeoff from Charles De Gaulle (CDG), sit on the Left side for the best views. CDG typically departs eastward on runways 08L/08R or 09L/09R, meaning a left-side seat faces north toward Paris city center. You get a clear view of the Seine river bends, the Eiffel Tower area, and the dense Haussmann grid of central Paris as the aircraft climbs out over the Île-de-France plain. Notable sights include: Seine river meanders through Paris, Eiffel Tower and Champ de Mars district, La Défense business cluster to the west, Bois de Boulogne forest patch.

When landing at Bangkok International (BKK), sit on the Left side for the best views. Suvarnabhumi Airport typically lands from the east on runway 19L/19R or approaches from the north, with the aircraft tracking south or southwest over the Gulf of Thailand coastline and the Chao Phraya delta. A left-side seat faces east toward the Gulf of Thailand and the flat delta wetlands, while a right seat looks inland over featureless suburban sprawl. However on the more common northerly approach, left side gives a view over central Bangkok's skyline and the Chao Phraya river bends before touchdown. Notable sights include: Chao Phraya River winding through Bangkok, Gulf of Thailand coastline to the southeast, Bangkok central business district skyline, flat mangrove and rice paddy delta plain.

The flight from Charles De Gaulle (CDG) to Bangkok International (BKK) takes Approximately 11 to 12 hours.

The route crosses the Alps southeast of Geneva, then tracks over the Adriatic Sea and Greece, crosses Turkey and the Caucasus region, passes over the Caspian Sea, crosses Iran and Pakistan, then descends over the Indian subcontinent and Bay of Bengal before approaching Thailand from the northwest. The Himalayas are visible as a distant white wall on the northern horizon during the India segment. The Caspian Sea is a distinctive inland body of water visible below during the Iran transit.
