Sit on the Left side of the plane for the best views on flights from Hakodate to Singapore. Left side wins both takeoff and landing. During the flight south, the left side also tracks along the western coast of Japan during initial climb, offering views of the Japanese Alps in the distance, and later passes over the South China Sea with views toward the Vietnamese and Malaysian coastlines as the flight descends toward Singapore.

During takeoff from Hakodate (HKD), sit on the Left side for the best views. Hakodate Airport typically departs runway 12 (southeast) or runway 30 (northwest). On a southbound flight to Singapore, a runway 12 departure heading southeast puts the left side facing northeast toward Hakodate Bay and the distinctive hourglass-shaped Hakodate Peninsula. The city of Hakodate and its famous harbor district are clearly visible on the left as the aircraft climbs and turns south. Notable sights include: Hakodate Bay and the narrow isthmus connecting the peninsula, Mount Hakodate (334m) at the peninsula tip, Tsugaru Strait to the north, Uchiura Bay (Funka Bay) to the west.

When landing at Singapore Changi (SIN), sit on the Left side for the best views. Changi Airport's primary arrival runway 02L/20R runs roughly north-south. Arriving from the north on runway 02 approach, the aircraft tracks over the Johor Strait and the northeastern tip of Singapore. The left side faces west over central Singapore, giving views of Marina Bay, the CBD skyline, and the reservoir system in the interior. The right side faces east over open South China Sea with little of interest. Notable sights include: Marina Bay Sands and CBD skyline, Johor Strait and the causeway to Malaysia, MacRitchie and Peirce Reservoirs in the central catchment area, East Coast Park and the southern coastline.

The flight from Hakodate (HKD) to Singapore Changi (SIN) takes Approximately 7 to 8 hours (no direct scheduled service exists; typical routing via connecting hub would add time, but a hypothetical direct flight would be roughly 7.5 hours covering about 5,300 km).

The flight path tracks south-southwest over Honshu and the Japanese Alps, crosses the East China Sea, passes over or near Taiwan and the Luzon Strait, continues over the South China Sea passing west of the Philippines, crosses over or near the northern tip of Borneo or the Sulu Sea depending on routing, and descends over the Malay Peninsula or directly over the South China Sea toward Singapore
