At what point, and how will trusted vs. non-trusted be identified ? Assuming airlines have access to this new list maybe you get a TTTT on the BP but even so, as discussed in another thread, there seems to be no requirement to speak to any TSA worker prior to the papers scrutineer (TDC). Unless there will be a pre-TDC TDC (which is entirely possible) these interrogations would have to be done inside the checkpoint.

You think it's slow now ? As I posted before, unless this program absolutely guarantees fast passage without any possibility for TSA workers to engage in capricious exception it will be just another cosmetic facade and money grab. Oh yes, you will have to pay.
