Hanoi to Singapore is 1,378 miles (2,218 km), a flight of about 3 hours 20 minutes.
The right side wins overall because the cruise phase passes near Cambodia's Tonle Sap Lake and the Mekong-Tonle Sap-Bassac river confluence at Phnom Penh, both highly distinctive from altitude, and the approach into Changi adds a clear view of Singapore's skyline across the Strait of Johor — together outweighing the left side's more limited, single-phase karst scenery at takeoff.
