When it comes to air travel, one of the most frequent questions passengers have is, “What is allowed in a carry-on bag?” If you break the rules and take something you weren’t supposed to on the plane, they’ll take it away from you at the security checkpoint. We don’t want that!
To keep you from having a horrible experience at the airport, we’re going to tell you everything you need to know about what you’re allowed to bring on an airplane. The Transportation Security Administration, also known as TSA, has lots of rules about what you’re allowed to take with you on an airplane. By familiarizing yourself with these details, you can pack your bags confidently, knowing exactly what is allowed to make your trip enjoyable and worry-free.
Quick Reference: What You Can and Can’t Pack in Your Carry-On

TSA Rules and Regulations
It’s important to learn and adhere to TSA’s regulations and guidelines for the smooth operation of airport security procedures. These etiquettes and their related norms have been established to help improve security and ensure that travelers are safe. These regulations apply to all carry-on luggage, such as suitcases, bags, and laptop cases, that you plan to take through security at the airport. If you’re unsure about the size limits for your carry-on bag, you can check “What size bag Is allowed for hand luggage?” to avoid any confusion. Knowing the air passenger rights related to what you can and cannot carry ensures that you don’t face unnecessary hassles during security checks. Additionally, having valid identification is crucial for passing through security. But in cases where you forget or lose your ID, you may wonder, “Can you fly without an ID?” Under certain conditions, you still can, though it may involve extra screening.
At the center of these regulations is the 3-1-1 rule, a philosophy guiding the TSA in its approach to regulating the transportation of liquids, gels, waxes, creams, and pastes in carry-on luggage. Here’s how it works:
- 3: Each traveler is permitted to carry travel-sized containers that do not exceed 3.4 ounces (100 milliliters) of liquid. This restriction is pivotal to the TSA policy, ensuring that only small amounts of liquids are brought on board. Duty free liquids purchased after clearing security are allowed in reasonable quantities.
- 1: All such containers must be placed in a single, quart-sized, sealable bag, streamlining the screening process.
- 1: Only one quart-sized bag is allowed per passenger, regardless of the number of carry-on items.
Keep in mind that one extra carry-on doesn’t equate to an allowance for more items that are otherwise prohibited. Containers larger than 3.4 ounces still cannot be included, even if partially filled. Medically necessary liquids and liquid baby food are allowed, but passengers must notify a TSA security officer of such items on their person.

Final Thoughts
As we conclude our guide to what you can pack in a plane carry-on — and for whom you must pack it — it’s important to remember that the TSA rules and the 3-1-1 rule for liquids are only the beginning of the guidelines on packing your carry-on luggage. Alongside these rules, ensuring that you have your boarding pass readily accessible is equally important, as it’s your gateway through airport security and onto your flight. Individual airlines may have further restrictions or allowances, like carry-on luggage size limits and carry-on bag weight restrictions, which will influence how you pack. Then again, international travel adds further complications, in that what is permitted in a carry-on bag can differ markedly from country to country.
Before you even board a plane, you need to understand TSA policy, your airline’s requirements, and the destination country’s entry rules. Not only will being prepared save you a lot of hassle, but it will also mean you can fully enjoy the more fun parts of your trip, with a much smoother and far less stressful journey as a result!
But as constraining as some may feel, these rules keep all of us safe with wings and wheels. Your awareness and attention to what you take on board is yet another way you positively impact a safer journey. Bon voyage!
