My only complaint about PHL is that for those of us who walk with canes, there could be more wheelchair pushers. It's a long walk from a domestic gate to one of the International gates. And, better scheduling by the TSA. Due to a officer shortage the day I came through on the way home, the bottleneck of several international flights' passengers all having to go through a single "sniffer" machine meant I missed my connection to DFW. All PHL-DFW flights for the rest of the day were overbooked. I had to take AE to Memphis where I had to sit for 2.5 hours in an almost empty concourse. I then had to take AE from MEM to DFW. I was supposed to get back to DFW approx. 2:30pm. Got there shortly after midnight. I was flying on my ATW pos space passes, but agent in PHL said the Pos space part only applied to my scheduled flight. Since I missed that, my passes were simply treated as NRSA.
