OKC does now, and it's usually convenient-Kinda funny, the first time I got an upgrade before showing at the airport, my first thought was "Great, I can skip the security line!" (I'm still Silver) ironically, after printing the boarding pass and dropping bags, I went over to the Sky Priority line....which had a dozen or so folks in it.......then noticed the cattle line was almost empty....I left the sky priority line, and walked around 8 or so still standing in the priority lane by using the regular line! Go figure.
Between 6 and 7 am on a Monday it's awful handy though!
