TyreCreep - I fully agree that legislation on the mandatory wearing of seatbelts be introduced. However, there is an aside to that on long sectors in the shape of DVT, with pax being encouraged to get up and 'walk' regularly.
Given the majoritively unpredictable nature of CAT (or other unforseen upsets), there is always going to be the risk (however small) of pax being 'glued to the bins' or getting rag-dolled around the cabin.
We certainly don't want to risk a DVT related death on the back of insisting pax only unbuckle to use the toilet, there has to be a very careful balance of both risks, and whilst the DVT risk is certainly lesser, it still exists and must be considered.
