The damage has already been done, with the threatened IA, to any BA forward bookings. Hence, if I were WW, I would just wait, and watch the lambs run to the slaughter. And slaughter it will be; there are plenty of other people out there who will do the job for less money.
What a shame BASSA didn't sit down, negotiate, and try to work out a solution (it was only 82 million, at the start). Too many egos, writing cheques they expect other people to cash, to miss-quote Top Gun.
