Antalya to Cairo is about 757 km and usually takes around 1h 30m in the air. The track it follows runs over the Anatolian plateau, the Mediterranean, and North Africa.
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 the air is usually calm and settled. Above North Africa daytime heat can stir shallow thermals lower down, but the air smooths out at cruise.
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.
