As far as de-icing early, many times that is impossible due to local conditions. The fluid only works for a limited time, (depending on conditions and type of fluid used it could be as little as 10 minutes to over an hour) so would only have to be redone it done too early. Because of this it is usually done as close to departure time as possible. It is an unfortunate reality that weather conditions can cause delays, but that is unavoidable unless you skipped de-icing but the consequences for that would be quite unpleasant...As far as the meals go, it can be a long day when these delays happen, but keep in mind the the carriers primary duty is safe transportation, and not being a flying restaurant. Most seasoned travelers take responsibility for their own nutritional needs and bring along at least some food to tide them over if delays occur.
