Lots of support being shown around LHR for the strikers from other staff and passengers, I would say BA's claims of "All planned flights will be operating as normal" are a little far fetched!
I imagine it takes quite a bit of courage to take part in a strike with this much publicity, but when you have very little to lose it probably makes the decision easier. I hear that the strike pay of £60/day the union are paying them will probably put more money in their pockets even after losing 2 days pay for stirking! (surley this can't be true?)
