Omlette - agree completely with your description of profit share. It has been that way since the profit share was first paid, donkeys years ago. As far as the 'bonus' goes though, and I stand to be corrected, I have never heard of anything like that being paid, at least not to pilots. There have always been rumours about Senior Management grades being given a 'bonus' for achieving some departmental target or other, but it has never been formally acknowledged or confirmed as far as I know. For pilots, the terms profit share and bonus have pretty much been used interchangeably.
