So here are some tips from a former frequent flyer: buckle up all the time! Even if you're just sitting there reading a book or watching the IFE. The stories you hear about turbulence injuries all comes from people not buckled in. Yes, Clear Air Turbulence can't be detected and if you are up and about to use the washroom, you're out of luck. It won't probably won't crash during turbulence incidents, is there a chance of being mishandled, yes, but the chances are pretty low. Look at the crashes in the last 5 years and see which operators are involved. How often you see the US big 3, CX, JAL, ANA, CI, and EVA having a major incident? Look up safety ratings online if you need a piece of mind. Finally, read the safety instructions a few times, memorize how many rows you are from the exit, ware pants and shoes (not shorts, skirts, crocs, sandals, high heels).
