The London to Reykjavík route drawn as a great circle arc on a globe

What the aircraft actually flies over

From London the path crosses United Kingdom, then 1,312 km of open water.

The furthest the great circle gets from the equator is 64.0°N, 100% 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 London the aircraft points north-west (326°); it arrives into Reykjavík heading north-west (307°). That is 19° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
