As a DeltaManiac for the past many years (11 years consecutive PM), I would like to explore my schedule with a view to coming to this event. I have to be in San Antonio for a convention/meeting until the 20th, so it might well be possible to head to ATL from there rather than return to BOS.
One outside event that could possibly alter many Delta employees schedule and availability would be if the Atlanta Braves make the baseball playoffs. Right now, they are in first place in their division.
