I saw that yesterday and had two thoughts.
First, I remember the days when AA had the Heavy Metal at T3, and flying into Sky Harbor was a real treat, as the big birds were what brought you in.
Second, the TSA has seriously messed up T3 with the security facilities. T3 was formerly a very welcoming, interesting architectural space, even after the first Gulf War restricted the piers to passengers only. After 9-11, though, T3 became downright claustrophobic with the TSA clogging up everything.
