Welcome to Flyertalk.

Although you may get the answers you're looking for here, I recommend you ask on TSA-oriented sites like

http://www.tsa-screeners.com/ (temporarily out of service - bandwidth quota issues) or

http://www.tsascreener.com/

This site is really all about airline points/miles and the experiences of frequent flyers. Your questions are sorta like a frequent flyer asking about mileage and upgrades on one of the above sites.
