# Copenhagen to Reykjavík: distance, flight time and the route it really takes

Copenhagen Kastrup to Keflavik is 2,144 km of great circle — 1,332 mi — and an estimated 3h 10m in the air. Both ends are in Europe.

## What the aircraft actually flies over

From Copenhagen the path crosses 1,645 km of open water, then Iceland.

The furthest the great circle gets from the equator is 64.0°N, 100% of the way along.

Flying the line that looks straight on a Mercator map — one constant compass bearing — would cover 2,170 km. That is 26 km further, about 1% more, and roughly 2m of extra flying.

Leaving Copenhagen the aircraft points north-west (310°); it arrives into Reykjavík heading west (279°). That is 31° 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 318 kg of CO₂e each way, counting non-CO₂ warming.
