Opted out on the 17th October at lax tsa agent was friendly allowed me to collect my carry on luggage as it came out of the X-ray machine and take it over to the area where the pat down was conducted. Pat down was quick and unobtrusive. Opting out was one of the things I was stressing over as I'd never done it before and had read some horrible stories on here, either it was my lucky night or the tsa are trying hard to restore their image.
