Sit on the Left side of the plane for the best views on flights from Jakarta to Singapore. Left side wins both departure and arrival. During the cruise northward over the Java Sea and into the Singapore Strait, the left side also faces west toward the Riau Islands and the Malay Peninsula coast, giving more geographic interest than the open South China Sea on the right.

During takeoff from Soekarno Hatta International (CGK), sit on the Left side for the best views. CGK's primary departure runway 25L/25R sends aircraft northwest before turning north toward Singapore. The left side faces east toward Jakarta's urban sprawl and the Thousand Islands (Kepulauan Seribu) scattered across the Java Sea. You get a clear look at the dense city grid and the bay. Notable sights include: Jakarta Bay (Teluk Jakarta) with its industrial port, Kepulauan Seribu (Thousand Islands) chain extending north, Jakarta's central business district skyline to the southeast, coastal reclamation areas along the northern waterfront.

When landing at Singapore Changi (SIN), sit on the Left side for the best views. Changi typically lands from the east on runway 02L/02R or from the west on 20L/20R. On the common easterly approach over the Singapore Strait, the left side faces north toward the Johor Strait and peninsular Malaysia, giving views of the causeway and southern Johor. On a westerly approach, the left side looks over central Singapore and the harbor. Notable sights include: Johor Strait separating Singapore from Malaysia, the Woodlands/Tuas causeway links, Singapore's central reservoir system (MacRitchie, Upper Seletar), Changi's reclaimed land and terminal complex.

The flight from Soekarno Hatta International (CGK) to Singapore Changi (SIN) takes Approximately 1 hour 45 minutes.

The flight tracks north-northwest over the Java Sea, passing over or near the Riau Archipelago (Kepulauan Riau) including Batam and Bintan islands, which are clearly visible from altitude as large green islands in shallow turquoise water. The Singapore Strait narrows noticeably on descent, with heavy tanker and container ship traffic visible below.
