## What the aircraft actually flies over

From Perth the path crosses 5,586 km of open water, then Sri Lanka, then India, then 1,632 km of open water, then Pakistan, then Iran, then Turkey, then 689 km of open water, then Russia, then Moldova, then Romania, then Ukraine, then Slovakia, then Czechia, then Germany, then Belgium, then United Kingdom.

The furthest the great circle gets from the equator is 51.5°N, 100% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 14,768 km. That is 259 km further, about 2% more, and roughly 19m of extra flying.

Leaving Perth the aircraft points north-west (313°); it arrives into London heading west (273°). That is 40° 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 2.06 t of CO₂e each way, counting non-CO₂ warming.
