Panama City → Istanbul Turbulence Forecast

Panama City to Istanbul is about 10,817 km and usually takes around 15h in the air. The track it follows runs over the North Atlantic, Western Europe, the Alps, and the Balkans.

Air lifting over the Alps can raise brief, light ripples at cruise; crews know these spots well and the movement stays gentle. Over Western Europe and the Balkans the air is usually calm and settled. Nearer the North Atlantic 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.

A flight this long spends hours at a high, smooth cruise. Even when one stretch is bumpy it is a small slice of the whole trip, and the aircraft treats it as routine.
