Clearly this is a very srerious matter that mixes the shade of uniform with lounge priviliges, surcharges and everything else. From the OP it appears that these must all be taken together. After a long haul flight I could not possibly enter a lounge if the staff are wearing yelllow in the morning. If it were afternoon it would be ok, but yellow in the evening would be incorrrect. The coloour of uniforms is number one on my agenda for improvement. Who is behind me on this? Who willl show solidarity? Can we go to FB/AF/KL with one voice here? Can we show what we really think about the important isssues? For me, uniform colour is number one on my list. Who is with me on this?
