Sit on the Left side of the plane for the best views on flights from Denpasar to Singapore. The left side delivers the standout moment of the flight — Bali's volcanic peaks on departure are genuinely dramatic and rare to see from the air. The rest of the flight northwestward over the Java Sea and Sumatra's eastern lowlands is relatively featureless from either side, and the Changi approach views on the right are interesting but not exceptional. The volcanic departure view tips the balance to the left.

During takeoff from Bali International (DPS), sit on the Left side for the best views. Ngurah Rai Airport's primary departure runway (Runway 09) heads east, meaning the left side faces north toward Bali's volcanic interior. You get a direct view of Gunung Agung and Gunung Batur as the aircraft climbs out over the Badung Strait. The right side looks south over the Indian Ocean with little of interest. Notable sights include: Gunung Agung (3,031m), Gunung Batur and its caldera lake, the Badung Strait coastline, Nusa Penida island to the southeast.

When landing at Singapore Changi (SIN), sit on the Right side for the best views. Changi Airport's primary arrival runway (Runway 02L/02R) approaches from the south, meaning aircraft track northward over the Singapore Strait. The right side faces east, giving views over the eastern Singapore coastline, Changi district, and the southern tip of the Malay Peninsula. The left side looks west toward the city center and Johor Strait but is often obscured by the aircraft's approach angle. Notable sights include: Singapore Strait shipping lanes, Changi Beach and eastern coastline, Pulau Tekong island, southern tip of the Malay Peninsula (Johor).

The flight from Bali International (DPS) to Singapore Changi (SIN) takes Approximately 2 hours 30 minutes.

The flight tracks northwest over the Java Sea, passing north of Java's eastern tip and then over the Karimata Strait between Kalimantan (Borneo) and Sumatra. The southern coast of Sumatra's Bangka-Belitung islands may be visible below. The final descent crosses the Singapore Strait with its heavy shipping traffic before landing at Changi.
