Both ends are in Asia. **Great circle** 822 km 511 mi **Estimated in the air** 1h 31m block time **Furthest from equator** 37.5°N at 0% along **One lap of Earth** 2.1% of 40,075 km Of the [292 routes catalogued here](https://orbitflights.app/routes), this is the 261st longest. The Seoul to Shanghai route drawn as a great circle arc on a globe ## What the aircraft actually flies over From Seoul the path crosses 802 km of open water. The furthest the great circle gets from the equator is 37.5°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 Seoul, south-west into Shanghai. Over this distance the curve has too little room to bend the compass. One economy seat on it is about 122 kg of CO₂e each way, counting non-CO₂ warming.
