also, they do not search your bags when you check in. you are already on the flight by that point. i have a friend who is a baggage inspector, he mainly looks for cash $$$. i dont think they are gonna stop the flight, have it turn around so they can arrest you under the suspicion that you have a couple of cc's of something that may or may not be legit... i also know this cuz i bring my HRT flights and never been asked about it.
