Much will become clearer by mid-day on Monday.
At that stage everyone will have a better idea of how many flights BA have been able to operate. BTW, I will believe BA's figures, bacause as a plc they are not allowed to lie.
And, I am sure, BASSA will have generated additional fictional statistics which will undermine their case, the people who pay their subs to the Union, and indeed disrespect the whole of BA's good and loyal staff.
