If you can get DL to reissue all in J for you great. Keep in mind prem economy or even J intra-Europe on AF means nothing. Oh wait, prem economy means sit towards the front, J means no one in the middle seat. Same seat, same food.
I have never had issues for the intra-EU segments and was always in Biz. They have changed that slightly. PV has moved before the curtain (like two or three rows of PV) and they do serve Intra-EU Biz food now. However, middle seat is not protected so is is pretty much Y.
