When preparing for a trip, packing a carry-on bag can often feel like a puzzle. What can I take? What’s off-limits? Will this item get me pulled aside for additional screening? If you’ve ever asked yourself these questions, you’re not alone. The TSA (Transportation Security Administration) has a long list of items allowed and prohibited in carry-on bags to ensure the safety of everyone on board.
In this guide, we’ll break down the TSA’s rules so you can pack with confidence and sail through security without stress. Whether you’re a frequent flyer or embarking on your first flight, this guide will clarify everything from liquids and electronics to special exceptions and prohibited items.
What is a carry-on bag?
Carry-on luggage comes in various styles and sizes, from hard-shell spinner suitcases to soft-sided weekender bags and travel backpacks. However, it must adhere to the size restrictions set by your airline. The TSA doesn’t set carry-on size limits; instead, airlines establish these regulations. Typically, most airlines impose a maximum size of 22 inches by 14 inches by 9 inches, including the wheels and handles.
Your baggage allowance can also vary depending on your ticket class. For instance, some basic economy tickets may only permit a personal item, such as a purse, rather than a full sized carry-on. Additionally, while the bag should be easy for you to lift into the overhead compartment, some budget airlines impose strict weight limits on carry-ons.
To ensure a smooth travel experience, it’s essential to verify your airline’s specific carry-on policies. Once you’ve confirmed your allowance, make sure to pack according to TSA guidelines, ensuring all items are approved for air travel.

Why is TSA Regulations so important?
The TSA’s primary responsibility is to protect passengers and aircraft by preventing hazardous items from being carried onto planes. While these regulations may seem strict or overly cautious at times, they serve a critical purpose.
In 2022, the TSA detected over 4,500 firearms at U.S. airport checkpoints. Nearly 88% of those firearms were loaded. Other prohibited items, such as explosives, knives, and flammable materials, pose similar risks. By enforcing carry-on regulations, TSA officers help prevent these dangers from reaching the skies.
Failing to follow these rules can result in confiscated items, fines, or even delays that might cause you to miss your flight. Knowing what’s allowed,and what’s not,is the first step to avoiding these potential disruptions.
What Can You Pack in a Carry-On Bag?
Here’s the good news: the TSA allows most essential travel items in your carry-on, as long as you follow their guidelines. If you want to avoid checked baggage fees, traveling with just a carry-on is often possible. Below are some key items you can pack in your hand luggage without worrying about airport security. For a complete list of permitted items, check the TSA’s official website.
Commonly Allowed Items
| Item | Allowed in Carry-On? | Notes |
|---|---|---|
| Electronics (Phones, Laptops) | Yes | Must be placed in a bin for screening at security. |
| Clothing and Footwear | Yes | No restrictions, but remember to pack efficiently. |
| Solid Food | Yes | Includes sandwiches, fruits, and packaged snacks. |
| Toiletries (Under 3.4 oz) | Yes | Must follow the 3-1-1 liquids rule (discussed below). |
| Medications (Prescription) | Yes | Inform TSA if medication exceeds normal liquid limits. |
| Baby Essentials | Yes | Includes formula, breast milk, and baby food. |
| Jewelry | Yes | Keep in carry-on to avoid loss or theft in checked bags |
| Travel-Sized Hair Products | Yes | Ensure each container is 3.4 oz or smaller. |
Electronics
Your carry-on is the ideal place for electronic devices like smartphones, tablets, and laptops. These items need to be easily accessible, as TSA officers will require them to be placed in a separate bin for X-ray screening at the security checkpoint. Power banks and lithium batteries should also stay in your carry-on, as they are not allowed in checked luggage due to fire risks.
Power banks and portable chargers must be carried in your carry-on luggage and should have a rating of 100 watt-hours (Wh) or less per battery. If you need to bring larger spare batteries, up to 160 Wh, you must obtain airline approval.
Personal Items
All personal electronics are allowed in your carry-on. Phones, tablets, and laptops should be easily accessible as they will need to be removed from your bag during security screening.
Clothing and shoes pose no issues, although packing smartly to save space is always advised. Small accessories like belts ,disposable razors and jewelry are also permitted.
Lighters and matches
Passengers are allowed to bring disposable lighters in their carry-on luggage, as well as one book of safety matches (non strike anywhere). However, strike anywhere matches are prohibited.
Nonflammable liquids under 3.4 ounces
Nonflammable liquids, gels, and aerosols, such as shampoo or deodorant, are permitted in hand luggage if they adhere to the TSA’s 3-1-1 rule. This rule allows you to bring a quart-sized bag of liquids, with each container limited to 3.4 ounces (100 milliliters) or less.
Food and Beverages
Solid foods like sandwiches, fruit, granola bars, and chips are allowed. However, any foods that contain liquids (like soups, sauces, or dips) must comply with the TSA’s 3-1-1 liquids rule. This means liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less and fit inside a 1 quart-sized bag.
Important Note: Empty water bottles are allowed through security, and you can fill them once you’re past the checkpoint. You cannot take bottled water or other large liquid containers through security unless they are purchased after screening.
Alcoholic Beverages
Alcoholic beverages are allowed in carry-on luggage if they are 3.4 ounces (100 milliliters) or less per container. These mini bottles must fit comfortably within a single quart-sized bag. However, be aware that while you can bring alcohol on board, the FAA prohibits consuming it on the aircraft unless it is served by a flight attendant. In other words, even though you can pack alcohol in your carry-on, it cannot be consumed during the flight.
Baby Food And Essentials
Baby food and related items are permitted in reasonable quantities. This includes baby food, formula, breast milk, and juice. Formula, breast milk, and juice should be taken out of your bag and screened separately. Additionally, ice packs, freezer packs, frozen gel packs, and other accessories needed to cool these items are allowed in your carry-on. Other baby essentials like carriers and child car seats are also permitted, as long as they can fit in the airplane’s overhead bin or under your seat.
Medications Items
Most medical items are allowed on airplanes and should be carried in your carry-on for immediate access. For example, contact lens solution must be in a bottle of 3.4 ounces or less to be carried on; otherwise, it should go in checked luggage. Prescription medications can be brought on board without issue.
Needles are permitted if they are accompanied by injectable medication. Heating pads, whether air-activated or electric, are also allowed as long as they do not contain flammable liquids or gases. Additionally, pill bottles are acceptable; the TSA does not require medications to be in prescription bottles.
When traveling with medical items, you may need to declare them to the TSA agent and undergo additional screening. Be prepared for items like needles and liquids larger than 3.4 ounces to be inspected.
TSA 3-1-1 Liquids Rule: How It Works
One of the most critical TSA rules for carry-on luggage is the 3-1-1 liquids rule. This rule limits the amount of liquids, gels, and aerosols you can bring on board, helping to prevent hazardous materials from being concealed in liquid form.
Breaking Down the 3-1-1 Rule:
- 3: Each liquid container must be 3.4 ounces (100 milliliters) or smaller.
- 1: All liquid containers must fit into 1 quart-sized resealable plastic bag.
- 1: Each passenger is allowed 1 bag of liquids.
The 3-1-1 rule applies to items like:
- Shampoo and conditioner
- Toothpaste
- Lotions
- Perfumes and colognes
- Gels (hair gel, gel-based sanitizers, etc.)
- Aerosols (deodorants, hairsprays)
Special Exceptions to the 3-1-1 Rule
There are certain exceptions to the 3-1-1 rule, including:
- Medications: Both prescription and over-the-counter medications are exempt, but they should be declared to TSA officers if they exceed the standard liquid limit.
- Baby Formula and Breast Milk: These are also exempt from the 3-1-1 rule but must be declared at the checkpoint. Breast milk and formula are subject to additional screening, but larger quantities are generally permitted.
For frequent travelers, purchasing TSA-approved travel bottles and containers can help ensure compliance with the 3-1-1 rule while allowing you to pack your favorite toiletries.

Medically necessary liquids and liquid foods for infants are exempt from these rules. If you are carrying such items, inform the TSA security officer.
To streamline your packing, opt for solid toiletries like soaps, deodorants, and shampoos when possible. For liquid products, consider travel-sized versions. Place your quart-sized bag of liquids at the top of your carry-on for easy access. Some carry-on bags come with removable TSA-compliant clear toiletry bags, which can simplify the security screening process.
