Turbulence
I fly frequently also and always keep my seat belt loosely fastened. I would like to say to SLF that in my experience a lot of pax do not realise the danger of wandering about the cabin,some cannot even open the toilet door ,some dont even hear the message "please put your seat in the upright position"!! I have seen pax walking to the toilet while almost touching down so not all pax are frequent flyers ,most think they are on a large Bus!!!
