I have handcarried two large Tiffanys-wrapped/boxed vases in the last year or so. I would never check those items in. I haven't had any problems with TSA and I am sure they vases were leaded chrystal. The vases were carefully wrapped by Tiffanys, boxed with a nice ribbon and put in bag. I would never be able to get the ribbon back on as nice as they ever did so I was glad TSA didn't ask to see the vases.
