Travelers have long been accustomed to packing liquids in their carry-on bags according to the TSA liquid limit, also known as the 3-1-1 rule. As more airports become equipped with advanced CT scanners that use 3-D imaging to detect hazardous liquids, the liquid limit rule could be scrapped entirely. Though screening and technologies vary at every airport, so, for now, the TSA liquid limit remains in effect. One by one, I picked them up, but sadly they were each over the 100mL liquid limit, so I put them back on the shelf. Note that prescription wet pet food does not count as an exception to the TSA liquid rule, even for service animals.
