Traveling by plane can be exciting, but the rules about what you can and cannot bring can sometimes feel confusing. One question many travelers have is about liquids: how many ounces can you take on a plane? To avoid any hassles at airport security, it’s important to understand the guidelines and prepare your luggage accordingly.
The TSA 3-1-1 Rule for Liquids
The Transportation Security Administration (TSA) has clear rules about bringing liquids, gels, and aerosols in your carry-on bag. Known as the 3-1-1 rule, it’s designed to make the screening process faster and more secure. Here’s how it works:
- 3: Each liquid container must be 3.4 ounces (100 milliliters) or less.
- 1: All containers must fit into one quart sized, clear, resealable plastic bag.
- 1: Each passenger is allowed only one bag.
This means you can bring multiple containers, but they all need to fit within the quart sized bag. If a container holds more than 3.4 ounces, even if it’s only partially full, it won’t be allowed through security.

What Counts as a Liquid?
You might be surprised by what’s considered a liquid under TSA rules. It’s not just water and juice, other items, such as these, are also included:
- Lotions and creams
- Shampoo and conditioner
- Toothpaste
- Perfume
- Hand sanitizer
- Food items like yogurt or honey
Even items like mascara and lip gloss fall under the liquid category, so it’s best to double check your toiletries before packing.
Can You Bring More Liquids in Checked Luggage?
The 3-1-1 rule only applies to carry on bags. If you’re checking a bag, you can bring liquids in larger containers without restriction. However, make sure they’re securely packed to prevent leaks during the flight. For example, wrapping bottles in plastic bags can help protect your clothes and other items.

Exceptions to the Rule
There are a few exceptions to the TSA’s liquid rules. These include:
- Medications: You can bring liquid medications in amounts greater than 3.4 ounces, but you must declare them to TSA officers at the security checkpoint.
- Baby Formula and Food: If you’re traveling with a baby, you can bring formula, breast milk, or baby food in reasonable quantities. These items must also be declared at security.
- Duty Free Liquids: If you purchase liquids at a duty free shop, they’re usually packaged in a secure, tamper evident bag. Keep the receipt handy in case security officers need to check it.
Tips for Packing Liquids
Here are some tips to help you pack liquids for your flight efficiently and avoid any issues:
- Use Travel Sized Bottles: Invest in reusable travel sized containers that meet the 3.4 ounce limit. They’re eco friendly and save money in the long run.
- Pack Essentials Only: Only bring what you’ll need during your flight. For example, if you’re staying at a hotel, they often provide toiletries like shampoo and lotion.
- Keep the Quart Sized Bag Accessible: Place your liquid bag in an easily accessible part of your carry-on. This will make it easier to remove for screening at the security checkpoint.
- Check TSA Guidelines: Rules can vary slightly depending on the airport and country, so check the TSA website or the equivalent authority in your destination country for the most up to date information.

Why These Rules Exist
The TSA’s liquid restrictions were implemented after an attempted terror plot in 2006 involving liquid explosives. While these rules may seem strict or inconvenient, they’re in place to keep all passengers safe.
Non Liquid Items to Pack Instead
If you’re worried about running out of space in your liquid bag, consider packing solid alternatives. For instance:
- Solid shampoo and conditioner bars
- Stick deodorant (not gel or aerosol)
- Toothpaste tablets
- Bar soap instead of body wash
These items don’t count as liquids, giving you more room in your quart sized bag.
Staying Healthy While Traveling
Packing smart isn’t just about following TSA rules, it’s also about keeping yourself healthy and comfortable during your trip. For example, staying hydrated is crucial, especially on long flights. While you can’t bring a full water bottle through security, you can bring an empty reusable bottle and fill it up after passing through.
To keep your energy levels up, consider packing snacks like nuts or protein bars. If you’re looking for inspiration, check out our article on Top 7 Protein Packed Snacks That Keep You Full for Hours. These snacks are not only convenient but also satisfying for travelers on the go.
