Navigating TSA is already stressful enough, from worrying whether you remembered to toss that old water bottle or accidentally packed a sunscreen larger than the limit. However, many travelers don’t know that TSA has a list of officially approved full size items people are allowed to fly with.
TSA is currently working on improving their screening process with the latest X-ray scanning equipment, computed tomography (CT)—yes, similar to CT technology used in the medical field for CT scans.
The current screening technology uses 2D images to secure the contents of carry-ons. However, CT technology creates a 3D image that can better detect explosives and other threats.
Several U.S. airports have already begun testing or installing CT technology. Louis Armstrong New Orleans International Airport (MSY), Baltimore/Washington International Thurgood Marshall Airport (BWI), Washington Dulles International Airport (IAD), and Ronald Reagan Washington National Airport (DCA) are all either using or phasing in CT scanners.
Through this technology, TSA hopes to eventually let travelers’ laptops and liquids remain inside their bags during the screening process. In time, TSA could even drop its 3-1-1 rule for liquids.
“We are always looking to incorporate innovative technology throughout the terminal to improve the passenger experience while improving upon our security posture,” said Christopher Murgia, TSA’s Federal Security Director for Maryland. “[BWI’s] new screening lanes offer enhanced security as well as an expedited screening experience.”
TSA is even looking at shoe scanning technology to eliminate the shoe removal requirement.
Though the 3.4oz liquid limit is still in place, there are 11 TSA-approved items that are allowed in full size through security. These items include:
- Live fish
- Prescription medicine (in gel, aerosol or liquid)
- Ice, gel, and freezer packs (necessary for medicines)
- Fresh eggs
- Baby formula
- Baby/toddler food & drink
- Biological specimen (non-infectious in preservative solution)
- Duty free items
- Wet batteries (non-spilling)
- Liquid teethers
- Over-the-counter medication
The fresh eggs and live fish may be shocking to you, but there’s even crazier non-liquids allowed in carry-ons—we’re talking antlers, artificial skeleton bones, solid cheese, bowling balls and so on.
