Not having any experience in this though I do have a couple of suggestions for you.

There is supposidly a list of things that you are not allowed to bring on the plane in your carry on luggage if any of the things that you want to bring, fall into any of these catagories keep them out of your carry on luggage, and put them in your other luggage. And so long as what you are bringing is not illegeal in the state you are leaving or the state you are going to, then there may not be much of a problem

But like I said I have had no experience in this, so....
