Booked a flight earlier today MSN-ATL. Was 1/9 for one seat available in F (717) (DM w/Reserve) There were 5 in C+ and when the upgrade was processed, I was moved up to 10C in C+ - I asked the GA why I was passed over for the 1 seat in F. She told me they try to sell it up to 30 mins before departure. Seems like a pantload. It was a last minute award flight, but if DL doesn’t honor their commitment to their most frequent flyers, at what point does this need to be addressed. I had the same thing happen in SDF earlier... seems like a bunch of nonsense. Is this their new post-covid policy??
