About This Route
Which side of the plane should I sit on flying from Noibai International (HAN) to Siem Reap (REP)?
Sit on the Left side of the plane for the best views on flights from Hanoi to Siem-reap. While takeoff offers the Red River Delta's intricate waterways on the right, the landing view of Tonlé Sap Lake—one of Southeast Asia's most visually distinctive geographical features—makes left-side seats the better overall choice for this route.
