Did you know there are NEW TSA carry-on rules for 2025 that could totally catch you off guard? If you’ve ever been stuck in line at airport security, frantically rearranging your bag or tossing out items, you’re going to want to hear this. Today, we’re breaking down the updated TSA liquid rules, revealing surprising bans, exceptions, and even a free tool that’ll make packing for TSA way easier—and it’s something most people don’t even know exists. Let’s dive into the New TSA Carry-On Rules!
First, let’s talk about the famous 3-1-1 rule. Even if you think you’ve got it down, stick with me because it’s one of the most misunderstood TSA guidelines. According to TSA’s Instagram (yes, they have one and it’s hilarious), over 130 million travelers left full water bottles in their carry-ons last year. That’s right, 130 million people forgot this basic rule, causing delays and extra baggage checks. Don’t be one of them!
TSA Carry-On Rules: The 3-1-1
So, what does 3-1-1 mean? The first “3” is for 3.4 ounces, or 100 milliliters. That’s the max size for any liquid, gel, or aerosol container you bring in your carry-on. And yes, it’s about the container size, not how much is inside. Got a half-full 4-ounce tube of toothpaste? Sorry, still not allowed. If it can spray, spread, pour, pump, smear, or doesn’t hold its shape outside the container, TSA counts it as a liquid.
Next up, the “1” refers to the quart-sized, resealable, clear bag that all your liquids need to fit into. Think Ziploc or a reusable travel bag. This bag has to be clear so TSA officers can easily inspect it. Pro tip: Many airports provide free quart-sized bags at the start of the security line. Grab one if you’re in a pinch. They’re also great for storing other things during your trip, like wet swimsuits or even dirty socks.
And the final “1”? Each traveler is allowed only one liquids bag. If you’ve got more than can fit, you’ll need to check it. But here’s a hack: If you’re traveling with someone who’s not using their full allowance, like a partner or kid, you can distribute your extras across their bag. This trick is a lifesaver if your skincare routine looks like a 10-step process!
TSA Carry-On Rules: Breaking the Rules?
Now, what happens if you break the rules? If your liquids bag is overstuffed or contains items that are too big, TSA will flag your bag, search it, and make you throw out anything that doesn’t comply. Once you’ve hit security, it’s too late to save those items, so pack smart to avoid heartbreak over a tossed-out bottle of expensive lotion.
But here’s where things get interesting: There are exceptions to the 3-1-1 rule for certain items, and knowing these can save you major hassle. Let’s talk about those exceptions.
First, prescription medications are exempt. This includes liquid meds stored in pre-filled syringes or pens, creams like steroid treatments, and even over-the-counter items like saline solution, cold medicine, or liquid nutrition drinks.
Always keep prescriptions in their original labeled containers to avoid questions. Medical gels and creams—like hydrocortisone or antibiotic ointments—are also allowed in larger sizes. Need to bring aloe vera gel or an eczema treatment? Totally fine.
TSA Carry-On Rules: Big Exception
Another big exception? Infant and child nourishment. Breast milk, baby formula, and even juice boxes are allowed in larger quantities. Ice packs for these items are fine too. Just make sure to declare these items at security, remove them from your bag, and place them in a bin for inspection. While the process is usually quick, plan for a few extra minutes in case it’s a busy day.
But… some rules have changed. Remember when you could carry up to 12 ounces of hand sanitizer during the pandemic? That’s over. Hand sanitizer now falls under the 3.4-ounce rule and must fit in your quart-sized bag. Even those tiny clip-on bottles? Yup, they count too. So double-check your bag before heading to the airport.
TSA Carry-On Rules: The Changes
One of the most confusing things about the New TSA Carry-On Rules is that they can change depending on the airport, the day, or even the hour. This unpredictability is intentional—it’s meant to keep everyone on their toes, making it harder for potential threats to game the system. Unfortunately, that means you need to be ready for anything, every time you fly. Even with TSA PreCheck, you might still have to remove your liquids bag depending on the equipment and staff on duty.
TSA Carry-On Rules: The Liquids
Now, let’s talk about the liquids that are completely banned, no matter what. These include toxic chemicals like pesticides, bleach, or corrosive cleaning agents. Self-defense sprays like mace or pepper spray? Also a no-go. Flammable liquids like lighter fluid, propane, or spray paint are strictly prohibited. And if you’re thinking about packing high-proof alcohol, think again. Anything over 70% ABV, like Everclear or 151-proof rum, isn’t allowed.

Let’s continue now because this is where things get fun: If you’re ever unsure about an item, there’s an amazing tool you can use—it’s called AskTSA. This free service lets you send a photo or even an Amazon link of your item to an actual TSA agent, and they’ll let you know if it’s allowed. You can reach them via email, Twitter, or Instagram. It’s a total game-changer.
TSA Carry-On Rules: An Example
For example, I recently asked about gel shoe inserts, which contain an unspecified amount of gel. Not all types of gel inserts are the same. So, some may be allowed, but others not. Overall, gel inserts might often raise eyebrows because they contain gel, which the TSA categorizes as a liquid under their rules.
This is due to the potential for gels to be used inappropriately, such as concealing prohibited substances or even posing security risks. While many gel inserts are perfectly harmless, TSA must err on the side of caution to ensure overall passenger safety.
TSA Carry-On Rules: The Facts
The issue comes down to how TSA screens items. Since gel is semi-solid and can’t be easily determined to be safe by just a visual inspection, gel inserts could require additional testing. For efficiency, the TSA often opts to limit such items altogether.
Here’s the fact: TSA does allow gel inserts if they are already inside your shoes. Yes, that’s the loophole! If the gel inserts are pre-installed in your footwear, you’re good to go. However, loose gel inserts, whether in your carry-on or hand luggage, are subject to scrutiny because they fall under the 3.4-ounce liquid rule. If they exceed this limit, you’ll likely be asked to leave them behind.
If you’re unsure whether your gel inserts will pass, contact TSA in advance through the AskTSA service. This ensures you have a clear answer before heading to the airport, sparing you last-minute surprises. And yes, people ask about some wild stuff. TSA’s Instagram once revealed that travelers have questioned if spaghetti is allowed through security. (The answer? Yes, as long as the sauce is mixed in with the noodles!)
TSA Carry-On Rules: Medications
Of course, not everything is a laughing matter. Some medications that are perfectly fine in the U.S., like Adderall, are illegal in other countries—even with a prescription. Japan, for example, has strict rules against medications containing pseudoephedrine or amphetamines. So if you’re traveling internationally, research the medication rules in your destination country to avoid serious trouble.
But wait, there’s more to navigating the New TSA Carry-On Rules than just liquids! Let’s talk about some often-overlooked carry-on restrictions and tips that can save you time and stress.
For starters, did you know that food items are frequently flagged during security checks? It’s not just about liquids; certain solid foods can also cause confusion. Items like peanut butter, hummus, or even some cheeses are classified as liquids because of their consistency. So if you’re planning to pack snacks, double-check if they’re TSA-approved.
TSA Carry-On Rules: Electronics
One more hot topic is electronics. While it’s well-known that laptops need to be placed in separate bins, did you know the same rule applies to certain tablets, handheld gaming consoles, and even power banks? TSA officers may require you to remove these items for screening. A helpful tip is to pack them in an easily accessible part of your carry-on, so you’re not fumbling through your bag at the checkpoint.
Now, let’s address TSA PreCheck. It’s a fantastic program for frequent flyers, allowing you to skip the hassle of removing shoes, belts, and jackets or unpacking electronics and liquids. But even with PreCheck, there are exceptions. If an officer suspects something in your bag, you may still face additional screening. Signing up for PreCheck is easy, though, and it can be a game-changer for your travel experience. Think of it as an investment in stress-free flying!
TSA Carry-On Rules: Global Travel
Oh, and let’s not forget about global travel. If you’re flying internationally, consider enrolling in Global Entry. It includes TSA PreCheck and speeds up customs processing when you return to the U.S. For international flyers, this program is a lifesaver, cutting down long waits after a tiring trip.
One more essential tip: Packing smart can save you not only time but also money. Overpacking often leads to surprise baggage fees, especially if your carry-on ends up needing to be checked because it’s overstuffed. Keep your items organized using packing cubes. They’re a game-changer for maximizing space and keeping things neat.
TSA Carry-On Rules: Family Lanes
And here’s something fun: Did you know some airports have special family lanes or lanes dedicated to experienced travelers? If you’re flying with kids, look for these family-friendly options. They’re designed to be more accommodating for parents with strollers and extra gear. On the other hand, if you’re a solo traveler who’s quick and efficient, seek out the express lanes.
If you’re feeling overwhelmed by all the rules, use the MyTSA app. This official app provides up-to-date security wait times, the New TSA Carry-On Rules, and even lets you search specific items to see if they’re allowed. It’s like having a personal TSA assistant right in your pocket.
