While the departure gives a brief, worthwhile look at Sri Lanka's coast and highlands, most of the flight is spent over open ocean with little to see; the arrival into Singapore compensates with a genuinely striking urban and maritime scene, tipping the overall balance to the right side.
Flight Path
The route's midpoint lies over the open waters of the Bay of Bengal and Andaman Sea, south of the Nicobar Islands and north of Sumatra, with no land in sight until the aircraft nears the northern tip of Sumatra and the Strait of Malacca later in the flight.
