Turbulence is a part of flying. The only big danger that turbulence presents is Clear Air Turbulence (CAT). This turbulence cannot be picked up on radar. A quick search on google should give you more information about this phanomenon. My cousin , who used to work for CE
(Nationwide , South Africa) as an F/A , experienced CAT while flying between CPT
. The 737-200 dropped 3000ft from FL320 to FL290. The pilots recovered the aircraft safely but unfortunately , my cousin who was working in the aisle , suffered a neck injury. This injury has prevented her from continuing as an F/A and had to take early retirement.
So , turbulence mostly ins't threatening to the state of the aircraft , but as someone mentioned , it will probably cause more harm to you than the aircraft. Whenever I travel , I always keep my seatbelt fastened throughout the flight. And no , I'm not afraid of turbulence and have no fear of flying at all.
So , buckle up and enjoy the ride
