# Hong Kong to Singapore: distance, flight time and the route it really takes

Hong Kong to Singapore Changi is 2,566 km of great circle — 1,594 mi — and an estimated 3h 41m in the air. Both ends are in Asia.

## What the aircraft actually flies over

From Hong Kong the path crosses 1,142 km of open water, then Vietnam, then 1,123 km of open water.

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 Singapore. Over this distance the curve has too little room to bend the compass.

One economy seat on it is about 380 kg of CO₂e each way, counting non-CO₂ warming.
