A recent TSA reminder is putting a hard number on a mistake plenty of travelers make without thinking twice. Pack the wrong item, even by accident, and the agency can levy civil penalties up to $17,062 per violation, per person. The list of banned items goes well past the obvious weapons and hazardous materials most flyers already know to avoid.
Your Curling Iron Might Be Illegal in Checked Bags Now
Cordless curling irons and flat irons that run on gas cartridges or butane are banned from checked luggage entirely, a fire risk in a cargo hold nobody can reach mid-flight. They’re still allowed in a carry-on, but only with a safety cover locked over the heating element to prevent accidental activation. Standard cord-powered curling irons and straighteners face no such restriction and remain fine in either bag.
Bowling Balls and Cast Iron Skip the Carry-On Line
Sporting goods and heavy cookware make the list for a more physical reason. Bowling balls and cast iron cookware are both barred from carry-ons, dense enough that security treats them as potential blunt-force risks rather than everyday gear. Corkscrews with an attached blade get the same treatment, since the blade portion alone crosses the line even if the corkscrew function is harmless.
A Foam Toy Sword Can Still Get Your Bag Flagged
Even harmless-looking kids’ items aren’t automatically safe. A foam toy sword counts as a banned carry-on item, and screwdrivers longer than seven inches face the same restriction, long enough that screening treats them as a potential weapon regardless of intended use. Vaping devices and e-cigarettes take the opposite restriction, banned specifically from checked luggage over battery fire risk.
Snow Globes and Candles Fall Under the Liquid Rule
Gel-type candles are banned from carry-ons outright, and snow globes get caught by the same logic that governs any liquid: anything over 3.4 ounces inside doesn’t clear security in a carry-on. Even novelty items like Magic 8 Balls likely run into trouble for the same reason, the suspended liquid inside that produces the toy’s answers.
One Phone Model Is Banned From Every Flight, Period
The Samsung Galaxy Note 7 remains the most extreme example on TSA’s list, barred from both carry-on and checked bags on any flight since 2016. The phone was recalled after its lithium-ion battery was found prone to overheating, catching fire, or even exploding, a risk serious enough that the ban has stayed in place for nearly a decade.
Not Every Mistake Draws the Maximum Fine
TSA’s own enforcement guidance confirms penalties can reach $17,062 per violation per person, with repeat violations resulting in higher penalties. In practice, the agency weighs whether a violation looks like an honest packing mistake or a deliberate attempt to get something through, along with a traveler’s cooperation and any prior history, before deciding how hard to come down.
There’s a Built-In Exception for the Smallest Travelers
The 3.4-ounce liquid rule isn’t absolute. Formula, breast milk, toddler drinks, and baby food are all allowed in a carry-on regardless of quantity, along with the ice packs used to keep them cold, since TSA classifies them as medically necessary. Travelers just need to flag these items for separate screening rather than packing them in with everything else.
Travelers Can Actually Decline the Body Scanner
Fewer flyers realize they can opt out of biometric facial recognition and full-body scanning altogether. TSA is legally required to honor that choice, though it typically means a longer screening process, including standard ID verification or a pat-down by an officer of the same sex instead. Travelers with mobility issues or medical devices can request accommodations like a chair during the process.
Five Minutes of Checking Beats a Four-Figure Fine
Between oversized batteries, blade-equipped tools, and liquid-adjacent novelties, the list of what TSA actually bans is far longer and stranger than most travelers assume. A confiscated snow globe is a minor inconvenience. A $17,000 penalty is not. Checking an item against TSA’s list before packing takes minutes and remains the only real way to avoid finding out the hard way at the checkpoint.
