What the aircraft actually flies over
From Santiago the path crosses Chile, then 11,057 km of open water.
The furthest the great circle gets from the equator is 61.7°S, 50% of the way along.
Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 12,774 km. That is 1,434 km further, about 13% more, and roughly 1h 47m of extra flying.
Leaving Santiago the aircraft points south-west (215°); it arrives into Sydney heading north-west (325°). That is 111° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.
