Good news as Larrude says. I checked the LGW home page (www.baa.co.uk) and DL does use the North terminal (same as BA). Still, you don't have too much time. I wouldn't risk if the ATL-LGW and LGW-CDG flights are not on the same ticket/itinerary. You could take a chance if DL really pads their schedule well (e.g., if the allowed flight time is 9 hrs or more).
