What the aircraft actually flies over
From London the path crosses France, then Italy, then 751 km of open water, then Albania, then Greece, then 548 km of open water, then Egypt.
The furthest the great circle gets from the equator is 51.5°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 London the aircraft points south-east (120°); it arrives into Cairo heading south-east (141°). 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.
