What the aircraft actually flies over
From Seattle the path crosses 4,125 km of open water.
The furthest the great circle gets from the equator is 47.4°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 Seattle the aircraft points south-west (240°); it arrives into Honolulu heading south-west (219°). That is 21° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
