YYC F/A is quite correct, I am on a higher payscale at MAN! only goes to show that the company (sometimes)values experiance.
While I was at LHR before going to do the L/H at man my take home was about 1,250 on average inc all allowances as the lowest grade flt supervisor.
Basically its pay v lifestyle. I recently saw one of our girls who now flies for virgin and commutes from Man. She looked rough and tired and wished she hadn't made the move, said she was overworked and being paid peanuts for it. As everyone says, the grass is not greener on the other side, but then if you don't try it youll never know. but the bmi lifestyle may not be for you!! I love it personally and have made great friends over the years.
Maybe your just getting itchy feet at V.S. What about going for promotion? would that not be more pay and make the job more interesting??
