## What the aircraft actually flies over

From Hong Kong the path crosses 452 km of open water, then China, then 258 km of open water, then Laos, then Thailand.

The furthest the great circle gets from the equator is 22.3°N, 0% of the way along.

Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.

The heading barely moves: south-west out of Hong Kong, south-west into Bangkok. Over this distance the curve has too little room to bend the compass.

One economy seat on it is about 250 kg of CO₂e each way, counting non-CO₂ warming.
