The TSA Amended its Rules About Some Checked Items
Briefly

Airport and airline security guidelines continue to evolve. The TSA announced it would no longer require travelers to remove their shoes at security checkpoints and advances in screening technology could eventually ease restrictions on liquids in carry-on bags. The TSA also moved to ban certain devices from checked baggage, specifically curling irons or flatirons that require butane or gas canisters and the butane or gas used to refill them. Irons with an attached safety cover can be packed in carry-ons. Several airlines have begun restricting or barring power banks on flights over fire risks after an incident forced an international flight to make an emergency landing in Boston.
Not every change in security policies involves things getting more lenient, however. The TSA also recently moved to restrict a number of devices from going in checked bags in the future. NBC News' Bethany Heitman reports that the agency recently added several devices and accessories to its list of materials banned from checked bags. These new restrictions apply to "curling irons or flatirons" that require butane or gas canisters to power them, as well as the butane or gas used to refill them.
Provided a safety cover is attached, the irons in question can be packed in a carry-on bag, however. The TSA isn't the only air travel stakeholder to adopt a more cautions approach when it comes to potentially volataile pieces of technology. Last month, The New York Times reported that a number of airlines had begun restricting the use of power banks while in flight - and, in some cases, barring them from flights entirely.
