The pilots try to limit the motion you will feel on the plane. They do their very best to keep the turns shallow and the motion to a minimum so that you can focus on the beautiful scenery and not have to worry. However, there are windy days here, and that does create turbulence in the air. The pilots try to avoid the more turbulent areas and to minimize turning as much as possible. You will not feel as much motion in a plane as you will on a boat — it’s more like a bus — but on a windy day, it is like a bus on a winding road. If you are motion-sensitive in a car, this is similar.
