A reality check through Atlanta this weekend:
Friday night 10/14 DL 1880 (SFO-ATL) 45 out of 46 for 2 seats on 757, my all time worst priority. I understand that this flight is ridiculously DL elite heavy. Talked to a Diamond Medallion (DL's highest level) who was 15th on the list (and not happy about it).
Sunday 10/16 DL 2094 (ATL-PHL) 24-24 for two F seats on 757.
Moral of the story:
When flying through Delta's major hubs at peak times, enjoy SkyPriority boarding, two free bags and AS EQM because that's probably all you are going to get.
