Alternately, call AS and ask for it. With your name, flight number, and date, AS can find the reservation.
Delta may have the record locator, but you don't get it from DL. I tried lately via phone (outside US) and directly at the ATL skyclub to no avail with both options. We don't have this info was the answer.
Calling AS is certainly better, if you are within the US
