The issue is that I would be carrying them into the US on an international flight, and then checking them in again at
Miami with American for a domestic flight and then again with Qantas at LA. So if 'carry on' that is three separate
security checks.
Best TSA has to offer is that its up to the airline and also at the discretion of the TSA officer at
security on the day - sigh - been there - seen how that goes.
