Just to complicate things further, I noticed in the fine print of my current United Airlines ticket this little gem. They now said " Effective July 9, 2018, Lithium batteries that are installed in any checked OR carry-on baggage must be removed by the customer. Once removed, they can be transported on board." Battery powered baggage? I assume that is what they meant? This I have not seen before, but who knows? I hope they are not referring to installed batteries in computers, cameras and such. That would be a nightmare. Anybody have any clarification on this?
