I think we may see less invasive pat downs like were done in the past, with back of the hand and asking you to turn down your pants waistband. That gives the impression that they're still looking for terrorists but avoids the public spectacle.

Separately I'm guessing the LEOs will be asked to vigorously enforce the photo/video policies of the airport. Since it's not clear when you walk in the terminal if the airport authority allows recording, we'll probably hear about a rash of phone/camera confiscations.

What will make it even more interesting is what the news outlets will do. Will they try to broadcast from the checkpoints? Will the airport authority keep them far away? Will we see a lot of feel good reports with smoothly running checkpoints and happy passengers accepting the AIT scan?

I fly on Thursday, hopefully it's a quiet day.
