Copenhagen to Paris is about 1,004 km and usually takes around 2h in the air. The track it follows runs over Scandinavia, Central Europe, the North Sea, and Western Europe.
Over the North Sea, Central Europe, and Western Europe the air is usually calm and settled. Nearer Scandinavia the weather turns more Atlantic and the ride can be livelier for short spells, still firmly within the routine.
On a flight this short most of the time is climb and descent, so any small movements come early and late; the cruise in between is brief but calm.
