What the aircraft actually flies over

From Zurich the path crosses Austria, then Hungary, then Romania, then Moldova, then Ukraine, then Russia, then 541 km of open water, then Turkmenistan, then Afghanistan, then Pakistan, then India, then 2,216 km of open water, then Malaysia.

The furthest the great circle gets from the equator is 47.7°N, 5% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 10,606 km. That is 301 km further, about 3% more, and roughly 22m of extra flying.

How these numbers are worked out

The distance is the great circle between the two airports’ real coordinates — the shortest path over a sphere, and the measure airlines and loyalty programmes use. It is computed, not looked up from a table of published routes.

The time is an estimate derived from that distance, using the same arithmetic Orbit uses when you log a flight without timestamps: a typical airliner block speed of 500 mph plus thirty minutes for taxi, climb and descent. Real schedules run longer or shorter depending on winds, air traffic control routing and how far the gate is from the runway. Aircraft also do not fly perfect great circles — jet streams, airspace closures and ETOPS limits all bend the path, usually by a few percent.
