Sit on the Left side of the plane for the best views on flights from Seoul to Jakarta. While right seats dominate the departure from Incheon, left seats provide superior views during the critical landing phase at Jakarta, which offers more dramatic and varied geography. The Citarum River, Jakarta Bay, and port infrastructure are more visually distinctive than the departure views.

During takeoff from Incheon International (ICN), sit on the Right side for the best views. Incheon typically departs runways 03L/03R (northeast heading) or 15L/15R (southwest heading). Right seats offer the best view of Seoul's urban sprawl and the Han River delta during northeast departures, which are more common. During southwest departures, right seats still capture the Yellow Sea coastline and Gyeonggi Province's industrial zones. Notable sights include: Han River estuary and delta, Seoul metropolitan area (visible as dense urban grid), Gyeonggi Province industrial zones, Yellow Sea coastline.

When landing at Soekarno Hatta International (CGK), sit on the Left side for the best views. Jakarta's Soekarno Hatta uses runways 07L/07R (east heading) or 25L/25R (west heading). Left seats during eastbound approaches capture the Citarum River's brown water, Jakarta's northern port district, and Java Sea. During westbound approaches, left seats show the approach over Jakarta Bay and the city's western industrial zones. East approaches are more common, making left the consistent winner. Notable sights include: Citarum River (distinctive brown coloration), Jakarta Bay, Port of Tanjung Priok (visible as container terminals and ship traffic), Java Sea.

The flight from Incheon International (ICN) to Soekarno Hatta International (CGK) takes Approximately 5 hours 15 minutes.

The flight path crosses the Yellow Sea, passes over the Korean Peninsula's western coast, then transitions over the East China Sea. Around the midpoint near Taiwan's airspace (though typically routed north of Taiwan), you'll see the Luzon Strait region. The route then continues south over the Philippine Sea, passing east of the Philippines, before descending toward Java. Notable water features include the transition from temperate to tropical waters, visible as color changes in the sea. The flight crosses the equator approximately 2 hours before landing.
