The Seoul to Bangkok route drawn as a great circle arc on a globe

## What the aircraft actually flies over

From Seoul the path crosses 697 km of open water, then China, then Thailand.

The furthest the great circle gets from the equator is 37.5°N, 0% of the way along.

Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.

Leaving Seoul the aircraft points south-west (231°); it arrives into Bangkok heading south-west (219°). That is 11° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 544 kg of CO₂e each way, counting non-CO₂ warming.
