I am describing the kiosks at TBIT. I saw no path to access the kiosk except waiting in the crew/disabled line. I don't remember the layout 100% as I had just come off of a flight from Australia that had been delayed 8 hours, but I do remember there being metal handrails separating me from the kiosk. I had to wait to get up to the CBP officer just to tell him I was waiting to use one of the GE kiosks. During my 5 minutes in the line I didn't see anyone else using them, so it was a bit frustrating just to stand there while they were unused compared to my experience at ORD. It was much better than the normal line, however.
