My recent post on the subject seems to have raised as many questions as I had tried to answer. In short, there is still a lot of confusion about what can, and cannot, be taken through the security checkpoint and, once through security, what items you might have purchased on the concourse can be taken on the airplane. Since these restrictions are subject to change by our friends at TSA when they believe the threats are changing, the most helpful thing I can tell you all is that, if you have questions, there is one place on the internet where you should always be able to get the most current information:
TSA's list of Permitted and Prohibited Items
I hope this helps. Thanks for all your questions and feedback. We appreciate it.
If, based on the TSA's latest rules, you have a great packing idea to share, let us know.
