Sit on the Left side of the plane for the best views on flights from Singapore to Cheju. Left side wins throughout: Singapore's city and harbor on departure, then the South China Sea and Philippine Sea coastlines during cruise, and Hallasan on approach to Jeju. The right side sees mostly open ocean for the majority of the flight.

During takeoff from Singapore Changi (SIN), sit on the Left side for the best views. Changi typically departs on runway 02L/02R heading north, which puts the left side facing west over Singapore's city center, Marina Bay, and the southern islands. You get a clear view of the CBD skyline and the reservoir system as the aircraft climbs out over the Strait of Malacca. Notable sights include: Marina Bay Sands and CBD skyline, Sentosa Island and the southern anchorage, Jurong Island industrial complex, Lower Seletar Reservoir.

When landing at Jeju International (CJU), sit on the Left side for the best views. Jeju International typically lands on runway 07, approaching from the west over the sea, which puts the left side facing south toward Hallasan, the dormant shield volcano dominating the center of the island. This gives the best view of the mountain and the island's dramatic southern coastline. Notable sights include: Hallasan (1,950m shield volcano, center of Jeju Island), Seogwipo city on the southern coast, Jeju City urban area, the basalt coastal cliffs of the southern shore.

The flight from Singapore Changi (SIN) to Jeju International (CJU) takes Approximately 5 hours 30 minutes.

The route tracks northeast over the South China Sea, passing east of Vietnam and the Vietnamese coastline, crossing the Taiwan Strait or skirting east of Taiwan depending on routing, then crossing the East China Sea before descending toward Jeju. The left side may catch distant glimpses of the Vietnamese coast and the Paracel Islands area in haze during the early cruise phase, and potentially the southern tip of Taiwan or its mountainous spine from distance during the mid-flight phase.
