Well, the TSA just rolled out a new list of banned items, and it’s making even the most seasoned travelers lose their patience.

Everyday things you’ve packed for years are suddenly off-limits, and officers are seizing personal belongings left and right. Before you find yourself arguing at an airport security checkpoint, here’s what changed, and how to avoid TSA tossing your belongings in the trash.
1. Cordless Hair Tools
These trendy cordless hair straighteners we all love so much? Sorry, but you can’t pack yours anymore.
The TSA has banned cordless curling irons and flat irons that use gas cartridges, butane, or lithium batteries in checked luggage, calling them a potential fire risk.
You can only bring them in your carry-on luggage, and even that comes with this fine print:
- The heating element must be covered and protected
- It can’t accidentally turn on mid-flight
- No spare gas cartridges allowed
If you’re not sure what kind of hair tool you own, you might want to leave it at home — because once TSA takes it, you’re not getting it back.
2. Lithium-Ion and Battery-Powered Items

If it plugs in, charges, lights up, and/or glows, the TSA has new rules for it now.
They now say lithium-ion and battery-powered devices must go in your carry-on suit case, and can’t be in your checked luggage.
The rule applies to the following common travel items:
- Power banks (aka portable battery chargers)
- Wireless headphones
- Portable electric fans
- Mini-massagers
- Vape pens and e-cigs
- Spare batteries ( Pro Tip: Store extra batteries in a case or sleeve, because if they roll around unprotected, you can still get flagged.)
The reason for the ban? According to TSA and the FAA is that these are a potential fire hazard in the cargo hold.
Of course, travelers find it confusing, and say it’s easy to get this wrong. My best advice is to keep anything with a plug in your carry on luggage.
3. Liquids and Foods (Like Peanut Butter)
First up, Liquids
Remember the TSA 3-1-1 rule for carry-on liquids? Here’s the deal, if you’re unfamiliar with it:
- Liquids, gels, creams, and spreads must be in containers that are under 3.4 ounces (100 ml)
- Everything must fit in a single quart-size clear plastic bag
- One quart-size bag per person (TSA makes no exceptions)
Some non-Liquid foods now count as a liquids
TSA still loves the 3-1-1 rule, and now they’re enforcing it harder than ever with new items counting as “liquids.”
Nowadays, TSA has clarified that peanut butter counts as a liquid, sparking outrage among travelers.
That means your full-size jar of Skippy is now contraband. If it’s in a container that is under 3.4 ounces (100 ml), then it’s ok.
and it’s not just Peanut butter
On a personal note, my nephew recently had his jar of Nutella confiscated, so it’s not just peanut butter, but other liquid-ish food items too!
To TSA, your shampoo, your lotion, and now your peanut butter, hummus and Nutella all constitute as “potential threats.”
4. Sharp Objects, Knives, and Other “Dangerous” Items
Sharp tools and souvenirs have always been touchy, but now agents are cracking down harder than ever.
Here’s what’s officially banned from your travel backpack, carry-on suitcase, and/or hand luggage:
- Knives, box cutters, and scissors with blades over 4 inches long (10 cm)
- Anything sharp that “looks like a weapon” (determined at their discretion)
- Multi-tools, Swiss army knives, pocket knives, and similar items
Keep in mind that even if an item isn’t banned, TSA officers can still confiscate it “at their discretion.” Bottom line: You’re at their mercy.
Many travelers are complaining that they’ve lost expensive pocket knives or tools they’ve carried for years — even when rules seemed unclear.
Erring on the side of caution, don’t put anything with a sharp point in your carry-on baggage. I lost an expensive pair of pointed tweezers because of this.
Pro Tip: Double-Check TSA’s “What Can I Bring?” List
Every few months, TSA quietly updates its rules, and most people never hear about it until it’s too late (like when they’re taking your stuff from you).
Since it’s your responsibility to know what you can/can’t bring, visit tsa.gov/travel/security-screening/whatcanibring before you fly.
Checking for updates to the TSA packing ban list will take you two minutes, but could save you hundreds of dollars in seized items, so it’s worth it.
