That will be interesting and probably a matter of who is looking at it and where it is packed. if it is in checked luggage it might make it through the screening and be no issue. If they don't allow it and it is in your checked luggage they do hold it in a security room. You will be notified to come to the 'naughty room' to collect your bags and they will let you know the process at that time.
