It doesn't mean you might not get through security if they are asleep at the switch, but don't count on it. Pack it good in your luggage or ship it UPS etc. to your destination.
A friend of mine who was traveling recently said he saw a couple of guys with cue cases in the gate area past security. Perhaps they just got lucky but more than likely they packed their cues in their luggage and were simply carrying the empty case on board.
If you are handicapped and use sticks, place the shaft in one and the butt in the other.... otherwise no solution -- have to check them in with your suitcase.....
