Seoul sits at 37.5665°N, 126.9780°E, while Bangkok is located at 13.7563°N, 100.5018°E. The initial compass bearing from Seoul to Bangkok is 232° (SW), so a great-circle flight path leaves Seoul heading roughly SW. 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 23.81° and the longitude difference is 26.48°. 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.
The geographic midpoint between Seoul and Bangkok is approximately 26.2623°N, 112.3749°E. This is the great-circle halfway position — the spot where you would be exactly 1,861 km from each city. On long-haul flights this point usually falls over open ocean or remote terrain, which is why in-flight maps often look "empty" mid-route.
Bangkok is roughly 1 hour behind Seoul. When it is 09:00 in Seoul, it is approximately 08:00 in Bangkok. Daylight saving time can shift the offset by an hour during certain months, so confirm the exact difference for your specific travel dates.
