I'd recommend calling or sending a tweet daily... it might be a pain in the butt, but you don't want to miss inventory opening up earlier for some reason.
EDIT: Update, apparently now I am seeing O=2 on the ATL-CDG AF689 segment. Call now and see if DL can see availability and get the upgrade processed.
