An FYI. and sorry if this has already been posted. Just flew FCO-ATL last Sunday. Delta has moved their check-in counters to Terminal 1 for all their flights to the US, so DO NOT GO TO TERMINAL 5 FIRST. Walk in to Terminal 1, and go to the right. You need proof that you are on a Delta flight to even enter the area to check in, so if you haven't gotten your boarding pass, print up your itinerary that proves you're on one of their flights.
