Bruce,

Sometimes you can call up and ask the security people, or drop by (not during peak times) and get the info str8 from the screeners.

I don't think metal that small would matter, but have heard reports of the sensitivity being turned way up on the detectors.

If I was going kilted, I would try to visit the airport first and ask the security people before trying to board. A USAK casual would be a good choice from what I have read about them here.

But as an old security guard, I might try asking the folks themselves.

Best ---
