Wish I could post a picture of the BA departure board. A sea of red from all the cancellations on short haul. Looks like they have pulled the plug on all shorthaul for the rest fo the day. My 14.50 departure now shoing 17.25 but no gate and it is now 17.20. The simple truth is that BA are not prepared, the have insufficient deicing, if any, actually working and they have lost control of their operation at T5. Back to the bad old days. They simply cannot be allowed to use weather as an excuse.This is simple operational management incompetance on a biblical scale.
