Might as well necro this thread instead of starting a new one. I have an upcoming trip to Canada that I'll be in first class for, but I connect first in ATL before a flight to SEA and then on to YVR. I know from the discussion on this board and Delta's rules that I'll have lounge access in SEA. But will I be able to access the lounge in ATL? Or will I only get it at SEA where I connect to the international leg of my itinerary? I'll have a first class ticket and PM status.

I believe the answer is yes, just wondering if anybody has any firsthand knowledge or experience.
