Jaysus, you have to wonder why they didn't realise it when WW said prior to the first strike: "I can tell you one thing, we'll be flying this weekend".
Remember Unite's statement on the eve of the 1st strike that BA's planned strike flight schedule was a "work of fantasy"? They were clearly deluded enough to think that WW was bluffing at the time. Hopefully Tony Woodley can inject some sense of realism now.
