I don't see how it should be the TSA's responsibility to enforce carryon rules. I have no sympathy for the airlines on this one. They created the problem by charging for bags. I don't blame people for trying to avoid these fees. I don't think we would see the same problems if they included one checked bag in the airfare. I think as long as the TSA continues it's war on liquids, the airlines should be forced to accept one checked bag as part of the airfare. I have no problem with them charging for a second checked bag or oversized bags.
