Copenhagen to Antalya is about 2,489 km and usually takes around 4h in the air. The track it follows runs over Scandinavia, Central Europe, the Balkans, the Eastern European plains, the Anatolian plateau, and the Mediterranean.
Air lifting over the Anatolian plateau can raise brief, light ripples at cruise; crews know these spots well and the movement stays gentle. Over the Mediterranean, Central Europe, the Balkans, and the Eastern European plains 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. This track threads jet-stream latitudes, so in winter you may feel a few minutes of light, choppy air high up; summer usually rides calmer.
For most of a flight this length you are at a steady cruise above the weather, where the ride is smooth; the livelier moments, if any, are short.
