## What the aircraft actually flies over

From Buenos Aires the path crosses Argentina, then 1,000 km of open water, then Argentina, then Chile, then 9,354 km of open water.

The great circle reaches 69.5°S, inside the Antarctic circle — which is why the route looks like a detour over the top of the world on a flat map, and like the obvious line on a globe.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 13,791 km. That is 2,025 km further, about 17% more, and roughly 2h 31m of extra flying.

Leaving Buenos Aires the aircraft points south-west (205°); it arrives into Sydney heading north-west (335°). That is 130° 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 1.67 t of CO₂e each way, counting non-CO₂ warming.
