## What the aircraft actually flies over

From Bangalore the path crosses India, then Nepal, then China, then Mongolia, then Russia, then 1,434 km of open water, then the United States, then 2,518 km of open water, then the United States.

The great circle reaches 70.9°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 16,115 km. That is 2,127 km further, about 15% more, and roughly 2h 39m of extra flying.

Leaving Bangalore the aircraft points north (20°); it arrives into San Francisco heading south-east (156°). That is 136° 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 1.98 t of CO₂e each way, counting non-CO₂ warming.
