So, I was looking at the schedules in the GDS for my upcoming trip and I noticed DL 2050 from Atl-JFK is shown as being sold out. there are four other flights that day and none of the others are showing sold out, they're all available for sale. I then went and looked at the seat map and while coach is almost completely full, which surprised me since it's still almost 2 months to departure, about half of first class is still open. This led me to wonder if the flight is really sold out, or is there a schedule/equipment change coming?
For interest, the flight operates with one of DL's BizElite configured Ex-TWA 757s.
