Thanks for the clarification, although I was only referring to having to ditch the locking folders. I didn't think the ditching of the fixed blade was needed, although it might be problematic (i.e. Less than legal) transporting it to and from the airport. Don't know what the laws there are pertaining to that.
As a side note, if its not illegal to own a locking blade, just carry it, another option could be to just ship it to your house prior to flying home.
