Both ends are in Europe. **Great circle** 830 km 516 mi **Estimated in the air** 1h 32m block time **Furthest from equator** 48.1°N at 100% along **One lap of Earth** 2.1% of 40,075 km Of the [292 routes catalogued here](https://orbitflights.app/routes), this is the 260th longest. The Bucharest to Vienna route drawn as a great circle arc on a globe ## What the aircraft actually flies over From Bucharest the path crosses Romania, then Hungary. The furthest the great circle gets from the equator is 48.1°N, 100% 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. Leaving Bucharest the aircraft points north-west (302°); it arrives into Vienna heading north-west (295°). That is 7° 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 123 kg of CO₂e each way, counting non-CO₂ warming.
