I think Carpe ,the BA purser's pay you saw recently is certainly not typical of the rest of the company.
Maybe it was a -one-off-,where they triggered some outstanding allowances.
I have friends who are psrs within the company,and earn half that or less.
Meanwhile, like many airlines , the new crew are lucky to take home £1,000/mth,and then try to survive in W.London.
There are some that are highly paid in the company,and get destination payments for places they don't like going to,alot of time off,and v.large long flight payments (clue:these people are not on s/haul) , but as we have just been asked to save a further £17m in cabin services ,perhaps these are the people who will be targeted for the shortfall.
