Yes. Recently (not sure how long ago) the location of the Flight Connections entry location for T3 was moved quite a ways from the old location. In addition to moving, they've made it somewhat more like T5 in that they require a BP (used to be no BP check going into T3) and added a Fast Track lane for elites and premium cabins, just like T5. It is on the far left as you enter the space.
Cheers.
I've found that the T3 Fast Track not that "Fast" at all. The last 3 times I've went through it, the regular security lines moved much quicker. Could have just been situational, but since there's only one scanner for Fast Track, it sometimes clogs up when they have 3-4 scanners open for the regular security.
