groundhand - I am sorry if you think that is is wrong for staff and their nominees to be upgraded when on rebate travel - just to make a few points.....firstly it is a perk as others have highlighted and what is wrong with that, when upgraded staff are appropriatley dressed and discreet, there are certain rules that have to be followed. Secondly the staff member on rebate travel that you are seated next to in Club/FIRST etc may actually be entitled to that seat subject to space availability due to length of service or level within the company.
There are a few exeptions to the rule and I am sure that if noticed then the CSD/Purser is informed and the matter dealt with.
Please do not begrudge us hard working staff one of the very few perks we have left
