Oh the claws are out on this one! Love it!
Just to toss a bit of fuel onto the fire, currently running on the BA BALPA forum is a thread of 'pilots who have been sent the wrong payslip to their home address'. One advises he got a LHR Purser' payslip, and most ungentlemanly spilled the beans- she got a shade under £3k takehome, and more than his goodself. Gross that up and you don't need to be a BA CSD, Purser will do nicely thankyou! Gross that up with Pension/tax added and you have got one amazing payment for cabin services- 3 weeks training and off you go!
