So you're ready to get aboard a flight and you've decided you'd like to place your bag aboard a different flight. Why would you want to do that? You're a TSA agent and you'd like to test the system with $100 bill. You take your totally mysterious bag, you head over to a JetBlue flight, you hand that one hundred dollar bill to the doorman, and poof! You've got that bag aboard, unaccompanied by you.
