Both ends are in Asia. **Great circle** 816 km 507 mi **Estimated in the air** 1h 31m block time **Furthest from equator** 28.6°N at 0% along **One lap of Earth** 2.0% of 40,075 km Of the [292 routes catalogued here](https://orbitflights.app/routes), this is the 263rd longest. The Delhi to Kathmandu route drawn as a great circle arc on a globe ## What the aircraft actually flies over From Delhi the path crosses India, then Nepal. The furthest the great circle gets from the equator is 28.6°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: east out of Delhi, east into Kathmandu. Over this distance the curve has too little room to bend the compass. One economy seat on it is about 121 kg of CO₂e each way, counting non-CO₂ warming.
