This new awareness week initiative began on Monday, according to the TSA.

“Holy smokes, Batman! We are excited to launch our first ever Prohibited Items Week,” the agency wrote in a post that showed a Batman-themed brass knuckle. “Follow along all week where we discuss common questions, crazy finds, and why we have certain rules!”

The TSA also shared a graphic that illustrates which airports have uncovered the highest number of firearms brought in by passengers.

In a news release sent out last month, the agency noted that more firearms have been discovered in airports throughout the pandemic despite there being fewer passengers than last year.

And it’s not just prohibited weapons and liquids that airline passengers have been caught traveling with. Last week, TSA officers at the John F. Kennedy International Airport in New York stopped tampered lithium batteries from making it onto an aircraft.

The passenger who had the modified power source in their carry-on told officers they had constructed a wired solar panel with the batteries, however, TSA disposed of the device since it was hazardous and not fit for air travel.

When preparing for future trips, the TSA has a detailed search engine to explain what can and cannot be packed along for the journey.
