Singapore to Vientiane is 1,153 miles (1,856 km), a flight of about 2 hours 30 minutes.
While the right seat wins at takeoff for the Singapore skyline, the left seat dominates the majority of the flight. Once airborne and tracking northwest, the left side faces the Gulf of Thailand coastline of peninsular Malaysia, then the Cardamom Mountains and Cambodian lowlands, and finally the Mekong River valley and Vientiane on descent. The left seat delivers more sustained geographic interest across the full route.
Flight Path
The route tracks northwest over peninsular Malaysia, crossing the Main Range (Titiwangsa Mountains) visible as a spine of jungle-covered peaks running north-south. Over the Gulf of Thailand the coastline of southern Thailand is visible. The flight then crosses the Cardamom Mountains and the Dangrek Range escarpment marking the Thai-Cambodian border. The Khorat Plateau of northeast Thailand — flat, dry, and patchworked with rice fields — fills the view for the final 200 miles before the Mekong River appears at Vientiane.
