I guess one benefit of the ongoing postal dispute will be that the BA strike ballot will take longer than normal! ^
But on a more serious note, if the vote is yes, then I really don't see a rosy future for BA. I really don't see what the cabin crew will gain here. The only outcome will be negative on all sides (crew, company and customer). They may be able to negotiate some sort of short-term improved package, but if BA loses any bookings over the the Christmas period as a result of this I would foresee that the number of job losses will increase significantly.
I'm about as loyal a customer as BA could wish for, but I'm already starting to make other plans for my December business travel.
