I think what peeves most people is the fact that there is little, if any information given to people regarding delays etc. Weather conditions aside, the latest fiasco is just one of many where "authorities" either are incapable or simply
will not provide any information to the poor traveller. Communication is a wonderful thing, and goes quite a long way to keeping the travellers onside and not simply feeling completely neglected - just how difficult is it to keep the public at large informed? Obviously, in the case of BAA and some airlines, extremely so!
