The report also mentions Bluesmart, a smart bag maker that says it's compliant with current regulations, but whose lithium batteries cannot be removed. "We are saddened by these latest changes to some airline regulations and feel it is a step back not only for travel technology, but that it also presents an obstacle to streamlining and improving the way we all travel," the company said in a statement given to CNN. Safety around lithium-ion batteries has been a topic of concern lately, with the FAA recently proposing a ban on laptops in checked baggage. Researchers continue to try and find safer alternatives, though none have come to market just yet.
