I traveled on Friday out of PHL and also noticed the pre-check on the kiosk screen.

As for the scanner, I still got 3 beeps, so maybe they are starting to phase in the light. I did recall that the beeps were very loud. I seem to remember a green light, but that might have been the barcode scanner laser.

I'm flying back out of ORD tomorrow, but without precheck. I guess my luck was bound to run out as a Gold w/o GE.
