I just came over to Delta from AA. I noticed the difference in Delta during the first few flights of my Status Challenge. The employees all (at least the ones I interacted with) appeared like they genuinely enjoyed their jobs.That;s certainly not something I saw as much on AA. Also, I remember boarding a DL flight DFW-ATL in F and there was a hand written note from the FA sitting on the pillow and blanket in my seat. I NEVER received that on AA (not saying it doesn't happen just not something I experienced). All in all, I would agree that there is something completely different about the corporate culture in regards to customers at Delta.
