Right seats capture the most continuous and dramatic geography: the Strait of Johor on departure, the Gulf of Tonkin crossing during cruise, and the Red River Delta approach into Hanoi. Left seats miss much of the water crossing and approach detail.
Flight Path
The flight crosses the Gulf of Tonkin (Bac Bo Gulf) heading northwest. At cruise altitude (around 25,000 feet), you'll see the Vietnamese coastline emerge gradually—first the narrow coastal plains, then the Red River Delta becoming visible as a distinctive patchwork of agricultural fields and waterways. The Tonkin Gulf itself is a broad, shallow body of water; on clear days, the transition from open water to the delta's complex river system and rice paddies is striking. The flight path typically passes east of Haiphong before turning toward Hanoi's inland location. No major mountain ranges are visible from cruise altitude on this route, but the general terrain rises from the flat delta toward inland highlands to the west.
