## What the aircraft actually flies over

From Frankfurt the path crosses Germany, then Austria, then Hungary, then Serbia, then Romania, then Bulgaria.

The furthest the great circle gets from the equator is 50.0°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 Frankfurt the aircraft points south-east (114°); it arrives into Istanbul heading south-east (129°). That is 15° 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 272 kg of CO₂e each way, counting non-CO₂ warming.
