After theGreat TSA Peanut Butter Debacle of 2023, many travelers were left wondering what other seemingly innocuous items they might have to toss when they put their carry-ons through airport security. The No-Go List isn’t just obvious items regulated by the3-1-1 rule, like water and juice boxes; it also includes avariety of foodswith questionable consistency and items that have nothing to do with food at all. Pluscats. Andboa constrictors.
When you’re packing, remember to limit anything liquid-y to3.4 ounces (100 milliliters)or less and to place those items in a clear, quart-sized plastic bag, one bag per traveler. Think the usuals, like shampoo, toothpaste, and aerosol or roll-on liquid deodorant (solid deodorant isn’t regulated by the 3-1-1 rule).
But here are some surprising items that the TSA prohibits in carry-on luggage.
Peanut butter
The TSA has spoken: In March, the airport-security agency nearly broke the internet when it declared that it considers peanut butter to be a liquid and therefore subject to the 3.4-ounce limit for carry-on bags. Its reasoning: “A liquid has no definite shape and takes a shape dictated by its container.”
As disappointed as PB fans were by this news, the puns have been almost enough to make up for it. Almost. As the TSA’s awesome Instagramreminded travelers recently: “Caught in a jam with more travel questions? Don’t skippy past our friends at AskTSA! You can now get your answers in a jiff through SMS. Simply text “TRAVEL” to AskTSA (275-872), the replies are smooth and never crunchy.”
Frosting
The fate of frosting is similar to that of its cousin peanut butter, and its doom was decided in Cupcakegate 2012, when a TSA agent in Las Vegas nixed a traveler’s cupcake-in-a-jar. In ablog post complete with a photo comparisonof a regular cupcake and a jar version, the TSA backed the agent’s call, arguing that frosting was a gel and therefore fell under the 3.4-ounce rule.
“Unlike a thin layer of icing that resides on the top of most cupcakes, this cupcake had a thick layer of icing inside a jar.” Disbelief ran rampant, and food scientists and chefs commented. In an argument for frosting’s freedom,Alton Brown explained to me at the timethat “By definition, icing is not a gel. We get that word fromgelatin, which implies coagulated proteins, so [frosting] is not. Technically frosting is a condensed syrup.”
Regardless, TSA has not budged, and in a Scrooge move during the 2022 Christmas season, it reiterated the ban with aTweet: “Oh snap! Traveling with your gingerbread kit? Solid foods and candy are good to go. If it’s frosting or icing not already on the house, it must follow our liquids rule in carry-on. Items need to be 3.4 oz. or less.” Points for more puns, I guess.
Freezer packs that aren’t frozen
If the freezer packs or bags of ice are solid, you’re good to go. Butonce that pack is melted or even partially slushy, it’s considered a liquid and is subject to the 3-1-1 rule. So if you’re, say, my mom, and you’re loading ice packs into a cooler of chopped liver to bring to your family for Rosh Hashanah dinner, make sure those packs are good and solid. No word on the chopped liver itself though.
Alcohol over 140 proof
Even if it’s decanted into tiny bottles,any booze over 140 proof(that’s 70 percent alcohol) is banned from carry-on bags. But we have to admit, skipping the Everclear andhigh-octane Puerto Rican rumon a flight seems like a smart move for a variety of reasons.
Some sports equipment
You can bring your lucky baseball, basketball, or soccer ball into the cabin—even bike chains and bike pumps are allowed. But the TSA draws the line at any sports equipment“that can be used as a bludgeon (such as bats and clubs).”So you’ll have to check golf clubs and baseball bats.
Wet pet food
If it’s too liquid-y, you’re likely tolose your pet’s lunch. . . to the TSA. So bring dry food and snacks if you’re flying with an animal, even if the food is prescription. Need we remind you to travel with pets appropriately, and to review all requirements and forms forservice and emotional support animals? Cats love suitcases, so make sure yours didn’t climb inside before heading to the airport.This guy forgot.
Ammunition
Some people will find this an obvious prohibition, but many (many) many people stillbring ammunition in their carry-ons. Or worse,actual guns(occasionally evenhidden in peanut butter). While some firearms may be allowed in checked luggage (albeit withlots of rules), they arenot allowed in the cabin—not even toys, cap guns, or historical replicas. And in case you were wondering,nunchuks,throwing stars(not evenBatman’s variety),pocket knives, andsaw bladesare all prohibited too.
