I put my TQC-14 into checked luggage when I'm checking a suitcase. But several times I've packed it in a carryon hard case, and last month for the first time I carried it just strapped to the outside of my Lowepro Fastpack 250, on a round trip from Boston to Washington, D.C. I've never had any problems with bringing a tripod, and that's over ~15 domestic and probably ~25 international trips. I'm not sure it matters, but I do have Global Entry / PreCheck.
