On August 21st, Donna Gold arrived at ATL, left her bags at Delta's curbside check in, passed TSA security screening using the Pre line, and boarded her Delta flight to NYC.
It was only after she took her seat on that flight that airline and TSA officials approached her and asked to see her boarding pass. After discovering that the name printed on her boarding pass was "Mark Dornan," she was informed that she was a security breach.
Donna was able to find proof that she was booked on that flight using her smart phone. After that she was assigned a different seat and was able to fly home.
Both the TSA and Delta are looking into the situation to determine who was responsible. The TSA has said that both Donna Gold and her luggage were screened, so there was no threat posed by her flying home.
