Pros: Upgraded to first class so had more room, nicer seats. No lines at TSA, had the first gate past security so a short walk. Nice shopping and food choices.
Cons: No meal served on flight, only drinks and cookies / popcorn. No entertainment at all. You have to provide your own device. There was wifi but not free, it was so slow I couldn't download the entertainment app, so I gave up and slept. No access to Delta lounge with domestic first class WTF?
