That's my point. If you have a GUC, you're better off using it on any X+ fare on DL to get into BE than to use it on AF with an expensive premium economy fare to upgrade into AF business class.
Similarly, I think the old fare class rules still apply for the upgrade from coach to premium economy on AF, which is an even worse deal.
