Ah yeah, I had the CSR last year, but cancelled when the annual fee rolled around and switched to the Amex Platinum, so there weren't any lapses in my lounge access.
Which lounge were you at with Priority Pass Select? I didn't think that included Delta or Centurion lounges.
Oh I guess I was at a different one - The Club at ATL. Free food, alcoholic beverages and wifi. Can't complain! I looked at the Amex Platinum but I wouldn't really be able to realize the benefit of the Uber rides and dining is definitely where I spend most of my money, where the CSR shines. I also like that I can transfer points earned from the Freedom and Freedom unlimited to maximize my point gain and take advantage of the CSR's 1.5x redemption rate.
