## What the aircraft actually flies over

From São Paulo the path crosses 15,395 km of open water, then Indonesia.

The furthest the great circle gets from the equator is 40.0°S, 36% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 16,514 km. That is 519 km further, about 3% more, and roughly 39m of extra flying.

Leaving São Paulo the aircraft points south-east (123°); it arrives into Singapore heading north-east (50°). That is 73° 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 2.27 t of CO₂e each way, counting non-CO₂ warming.
