Singapore sits at 1.3521°N, 103.8198°E, while Seoul is located at 37.5665°N, 126.9780°E. The initial compass bearing from Singapore to Seoul is 28° (NNE), so a great-circle flight path leaves Singapore heading roughly NNE. Because the Earth is curved, the actual heading shifts gradually along the route — pilots and navigation systems update it continuously instead of holding a single fixed compass bearing.
The latitude difference is 36.21° and the longitude difference is 23.16°. Each degree of latitude represents about 111 km, which is one reason cross-latitude routes feel longer even when the map looks similar to east–west journeys.
