I'm curious how this pertains to me since I'm a paying customer. The only non-revving I did on DAL was back in the early 90's when DAL was in its prime and that's because every other kid I went to school with had a parent who worked at DAL. The only career Deltoids that stuck with DAL after the bankruptcy were pilots, stews and mechanics.
The only first class sitting I'm doing is Business Class on AT and IMO GK is making a bad decision letting if go away. I think reasonably priced business class is a major reason why AT has kicked so much ass in ATL over the last decade. I need to make a last minute run to Baltimore next week and AT Business Class was about $480/leg and you can't beat that with a stick.
