Sorry, no photos to show. The main comment was that these flights filled up quickly, and then there were many "no shows" apparently.
When I submitted my name I was told the only flight available was the "circle flight" around BOS. I was happy to get this and took the early AM flight to BOS. There were only about 150 passengers on the circle flight, and when I mentioned to Pete Sanson ( a dispatcher who coordinated this project) he said "Why don't you ride back with us".
The return flight to ATL only had about 100 passengers onboard, and as you mentioned the flight Shirley was on only had 74.
It turned out to be a great day for me. I was there the day we gave Ship 102 to DL, and was glad to be a part of its retirement. I can tell you there was a lot of the "old Delta Spirit" on that flight!
