I have a feeling I somehow got screwed.. flying DL 690 on the 14th from JFK-SEA. Just a few days ago there were 4 F seats available and I had been on the waitlist for a month. I checked just now and that is, I believe, after the 3 day upgrade window (where complimentary DM upgrades occur (?) and there is 1 F seat left and my waitlist has not cleared.
I am DM and was on the waitlist. It's possible, of course, that they sold these seats but it feels a bit strange to me. Is it possible I got shafted somehow?
Another confusing thing about this flight is that I sometimes Delta shows me F seats, other times it shows me D1 seats.
