UFG,
Shortly before I parted company with BA CitiExpress, cabin crew pay varied from base to base.
I'm not aware of your location, so just be prepared for it to be considerably less than that already mentioned.
I am refering to Brymon salary, so maybe the salaries have been brought in line since the merger.
Be prepared to work hard if you get through, but at the end of the day, its what you make it.
Good Luck!
