The Seoul to Shanghai route drawn as a great circle arc on a globe
What the aircraft actually flies over
From Seoul the path crosses 802 km of open water.
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.
The heading barely moves: south-west out of Seoul, south-west into Shanghai. Over this distance the curve has too little room to bend the compass.
