What exactly can the UK government do at this time? Yes there are a lot of people affected including myself...but I dont see what anyone can do. We are just waiting for this volcano to stop, and/or the weather pattern and winds aloft to divert the ash elsewhere.
Once this happens and the airspace is open, then they may be able to get something set up. Its one of the downsides of living on an island - limitted ways on and off it.
