Wonder why there was a differential effect with T5 being closed earlier and for longer. Could it be that the specification of service level agreed between BAA and BA was inadequate? Why did BA cancel many of their flights on Thursday when there was no weather reason to do so, apart from at Aberdeen? One gets the impression that BA can't be bothered when things get too difficult, and the management have lost control to the extent that the inconvenience of the staff is a higher priority than that of the passengers. There were hardly any BA staff to be seen anywhere on when the chaos started on Thursday, and the low level customer service people who were around were not empowered to do anything. "Landing" or getting people out of the terminal is a shambolic event, which seems more akin to the "kettling" techniques for controlling riots.
They don't need to go to the Geneva etc to find out how to keep an airfield open, Newcastle will do, where several of the BA longhaul fleet are presently residing.
