Wow, so much inaccuracy its startling. Pay is as per the standard FO pay (which has just increased again with the BALPA negotiated payrise), if 75% part time your hours are capped at 675 hours (shock horror, 75% of 900). Also the loyalty pay has been switched into a loyalty bonus instead, so the payment isn't guaranteed unless the company is producing a profit.
Bit confused as to what your issue is to be honest and why your information is so horribly incorrect. . .or if you are even an EZY pilot.
