So, you're planning a trip with Southwest Airlines and wondering about those pesky liquid rules for your carry-on? You've come to the right place! While Southwest has its own baggage policies, when it comes to liquids in your carry-on, they defer to the Transportation Security Administration (TSA). This means the famous "3-1-1 Rule" is your golden standard.
Let's break down exactly how much liquid you can carry on Southwest Airlines, ensuring a smooth and stress-free journey.
Step 1: Understand the Core Principle: The TSA 3-1-1 Rule
Before we dive into specifics, let's get acquainted with the fundamental rule governing liquids in carry-on bags for all flights departing from US airports, including those on Southwest.
The 3-1-1 rule is a mnemonic designed to help you remember the regulations:
-
3 stands for 3.4 ounces (or 100 milliliters). This is the maximum size for each individual liquid container you can bring.
-
1 stands for one quart-sized bag. All your liquid containers, each 3.4 oz or less, must fit comfortably into one clear, resealable plastic bag that is approximately quart-sized (about 6 x 9 inches or 20 x 20 cm).
-
1 stands for one bag per passenger. You are limited to one such quart-sized bag of liquids per person.
Think of it this way: If you can spill it, spray it, spread it, pump it, or pour it, the TSA considers it a liquid, gel, or aerosol, and it falls under the 3-1-1 rule. This includes a surprising array of items, from toothpaste and hair gel to peanut butter and hummus!

Step 2: Gather Your Liquid Essentials
Now that you know the rule, let's start preparing your carry-on liquids.
Sub-heading: Identifying "Liquids"
It's crucial to correctly identify what the TSA considers a liquid, gel, or aerosol. Here's a non-exhaustive list of common items that are subject to the 3-1-1 rule:
-
Toiletries: Shampoo, conditioner, liquid soap, lotion, moisturizer, sunscreen, toothpaste, mouthwash, hair gel, shaving cream, deodorant spray, perfume, cologne, liquid makeup (foundation, mascara, liquid eyeliner).
-
Food Items: Water, juice, soda, alcohol (under 70% ABV), soup, oils, sauces, salad dressing, honey, syrup, jam, jelly, pudding, yogurt, cream cheese, hummus, peanut butter, salsa.
-
Other: Contact lens solution, insect repellent (liquid/gel-based hand sanitizers).
Sub-heading: Selecting the Right Containers
Tip: Don’t overthink — just keep reading.
This is where the "3.4 ounces or less" comes in.
-
Travel-Sized Bottles: The easiest way to comply is to purchase pre-filled travel-sized toiletries. These are readily available at most pharmacies and supermarkets.
-
Refillable Containers: To be more sustainable and cost-effective, invest in a set of reusable, empty travel bottles that are 3.4 ounces (100 ml) or less. You can then decant your favorite larger bottles of shampoo, conditioner, etc., into these smaller containers. Make sure they have secure caps to prevent leaks!
-
Check the Label: Always double-check the volume stated on your product's packaging. Even if a bottle looks small, it might exceed the 3.4 oz limit. If it's over, it stays behind or goes in checked luggage!
Step 3: The Quart-Sized Bag – Your Liquid Organizer
This is the central piece of the 3-1-1 puzzle.
Sub-heading: Choosing Your Bag
-
Clear and Resealable: The bag must be clear and resealable. A standard Ziploc freezer bag (quart size) is the most common and widely accepted option. You can also find purpose-built TSA-compliant toiletry bags that are clear and resealable.
-
No Overstuffing: The key is that the bag must be able to close completely and lay flat without bulging. If you're struggling to zip it shut, you likely have too many items or items that are too large.
Sub-heading: Packing Your Bag Efficiently
-
Maximize Space: Arrange your containers strategically within the quart bag. Smaller, flatter items can go in first, followed by bulkier ones.
-
Upright is Best: Whenever possible, try to keep bottles upright to minimize the chance of leaks, even with secure caps.
-
One Bag Only: Remember, only one quart-sized bag of liquids is allowed per passenger. This means you can't have a separate bag for your lotions and another for your toothpaste. All 3-1-1 compliant liquids go into that single bag.
Step 4: Special Considerations and Exceptions
While the 3-1-1 rule covers most liquids, there are important exceptions that can significantly impact your packing. Southwest, like all airlines, adheres to TSA's allowances for these specific items.
Sub-heading: Medically Necessary Liquids
-
Exempt from 3-1-1: Liquid medications that are medically necessary are exempt from the 3-1-1 rule. This includes prescription medications, as well as essential non-prescription liquid medications (like cough syrup, saline solution, or certain dietary supplements needed for a medical condition).
-
Declare Them: You must declare these liquids to the TSA officer at the start of the screening process.
-
Reasonable Quantities: You are allowed to carry them in "reasonable quantities for your flight." This generally means the amount you would need for the duration of your travel plus a little extra in case of delays.
-
Original Packaging (Recommended): While not always required by TSA, keeping prescription medications in their original, clearly labeled containers can help expedite the screening process.
-
Additional Screening: Be prepared for medically necessary liquids to undergo additional screening, which may include being asked to open the container for testing. You can request a visual inspection if you prefer not to have your medication X-rayed.
Tip: Keep your attention on the main thread.
Sub-heading: Baby Formula, Breast Milk, and Toddler Drinks
-
Exempt from 3-1-1: Formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches) are also exempt from the 3-1-1 rule and can be carried in quantities greater than 3.4 ounces (100 ml).
-
Declare Them: Always declare these items to the TSA officer at the checkpoint.
-
Separate Screening: They will need to be removed from your carry-on bag and screened separately.
-
Cooling Accessories: Ice packs, freezer packs, and gel packs used to keep these items cool are also allowed in your carry-on, regardless of whether breast milk is present.
-
No Child Needed: You do not need to be traveling with an infant or child to bring breast milk.
Sub-heading: Hand Sanitizer (Temporary Exception)
-
During the COVID-19 pandemic, the TSA temporarily allowed one liquid hand sanitizer container up to 12 ounces per passenger in carry-on bags. However, it's crucial to note that this was a temporary exemption and can change. Always check the latest TSA guidelines before you fly, as this specific exemption may no longer be in effect or could revert to the 3-1-1 rule. As of current information, standard hand sanitizers fall under the 3-1-1 rule (3.4oz or less).
Step 5: At the Security Checkpoint
Once you've packed your liquids according to the rules, the final step is navigating the airport security.
Sub-heading: Easy Access is Key
-
Remove Your Bag: When you reach the security checkpoint, always remove your quart-sized bag of liquids from your carry-on luggage and place it in a separate bin for X-ray screening. This is a common requirement for all passengers.
-
Declare Exceptions: If you have medically necessary liquids or breast milk/formula, inform the TSA officer immediately before your bags go through the X-ray machine.
Sub-heading: What if I forget or my item is too big?
-
Confiscation: If a liquid item in your carry-on does not comply with the 3-1-1 rule (either the container is too large or it's not in the quart bag), the TSA will confiscate it. There are no exceptions for forgetfulness.
-
Checked Baggage Option: For any liquids that exceed the 3.4-ounce limit or don't fit in your quart bag, your only option is to pack them in your checked baggage. Remember that larger liquids in checked bags should also be securely sealed to prevent leaks.
By following these steps, you'll be well-prepared to breeze through security with your liquids on your Southwest Airlines flight. Happy travels!
