## What the aircraft actually flies over

From Helsinki the path crosses Finland, then Russia, then China, then Russia, then 705 km of open water, then Japan.

The great circle reaches 67.3°N, inside the Arctic 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 8,782 km. That is 953 km further, about 12% more, and roughly 1h 11m of extra flying.

Leaving Helsinki the aircraft points north-east (51°); it arrives into Tokyo heading south-east (152°). That is 101° 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 1.11 t of CO₂e each way, counting non-CO₂ warming.
