With the falling snow ,BA have cancelled their entire Heathrow departure programme today from 1000 to 1700. Other operators appear to be operating as close to normal as possible, albeit with delays. Blanket cancellations in times of uncertainty have been "The BA way" or "Policy" for some time now , rendering them the least good choice of airline out of their home base on such occasions. Does anyone have any idea what prompted today's decision? Anything to do with industrial relations?
