I agree.. you can try complaining to the ATUC's at
complaints@auc.org.uk , but to be honest, I think you will find the weather related delays tend to get short shrift. I know that you feel that it was only your aircraft, but if you go back and look at the stats, you will almost certainly find that if the airfield was closed for one hour, there will have been significant delay's throughout the day. De-icing is problematic. Detroit has that weather all the time in winter, so probably has more infrastructure to cope with it, but I agree.. we appear in the UK to be chronically unprepared for weather extremes
