Navigating airline regulations, especially when it comes to packing liquids, can be a real head-scratcher! You're probably thinking, "Is my favorite shampoo going to make it through security, or will it end up in the bin?" Don't worry, we're here to break down exactly how much liquid is allowed on Southwest Airlines, ensuring your journey is as smooth as possible.
Let's dive in and get you prepped!
Step 1: Understand the Golden Rule: The TSA's 3-1-1 Rule!
Alright, let's start with the absolute foundation of liquid allowances for all airlines flying within or departing from the United States, and that includes Southwest. Have you heard of the 3-1-1 rule? If not, pay close attention, because this is your key to hassle-free liquid packing for your carry-on!
What does 3-1-1 stand for?
3: Each liquid, aerosol, gel, cream, or paste you bring in your carry-on must be in a container that is 3.4 ounces (100 milliliters) or less. This is the container size, not the amount of liquid inside. So, even if you only have a tiny bit of lotion left in a 5 oz bottle, it's the 5 oz bottle that's the issue.
1: All of your travel-sized liquid containers must fit into one (1) quart-sized, clear, resealable bag. Think of a standard Ziploc freezer bag – that's the perfect size.
1: Each passenger is limited to one (1) such quart-sized bag. No exceptions for more bags!
Why this rule? The 3-1-1 rule was implemented by the Transportation Security Administration (TSA) to enhance aviation security by limiting the amount of liquids that passengers can carry on board. It helps prevent potentially dangerous liquid explosives from being brought onto aircraft.

Step 2: Packing Your Carry-On Liquids Like a Pro
Now that you know the 3-1-1 rule, let's get practical about packing! This is where you can be smart and organized.
Sub-heading: Choosing the Right Containers
Travel-sized everything! Hit up your local pharmacy or travel store for travel-sized versions of your everyday toiletries. Shampoos, conditioners, body washes, lotions, toothpaste, and even some makeup items (like liquid foundation or mascara) come in convenient 3.4 oz or smaller sizes.
Decanting is your friend. If your favorite products don't come in travel sizes, invest in a set of reusable travel bottles. You can decant your larger bottles into these smaller, compliant containers. Make sure they are clearly marked with their volume!
Sub-heading: The Magic Quart-Sized Bag
Clear and Resealable is Key: The TSA explicitly states that the bag must be clear and resealable. This allows security officers to easily see the contents without having to open and rummage through your toiletries.
Don't Overstuff: While you want to maximize space, ensure that your containers fit comfortably within the quart-sized bag and that you can easily seal it completely. If it's bulging and won't seal, you'll likely be asked to remove items.
Strategically Place Your Bag: When going through security, you'll need to remove your quart-sized bag from your carry-on and place it in a separate bin for X-ray screening. Pack it in an easily accessible spot in your carry-on to avoid holding up the line.

Step 3: Understanding Liquids in Checked Baggage
Good news! When it comes to liquids in your checked baggage on Southwest Airlines (or any airline, for that matter), the rules are far more relaxed.
No Size Restrictions (Mostly): For most liquids, aerosols, gels, creams, and pastes, there are no individual container size limits when packed in your checked luggage. Want to bring your full-sized shampoo bottle? Go for it!
Quantity Limits for Certain Items: While individual container sizes aren't restricted, the Federal Aviation Administration (FAA) does have overall quantity limits for certain restricted medicinal and toiletry articles (including aerosols) in checked baggage. The total aggregate quantity per person cannot exceed 2 kg (70 ounces) or 2 L (68 fluid ounces). The capacity of each contain
er within this limit must not exceed 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). This mostly applies to things like hairspray, deodorants, etc., that are considered aerosols. Pack Smart to Prevent Leaks: Even though there are fewer restrictions, imagine opening your suitcase to find your clothes soaked in lotion! To avoid this:
Place all liquids in sealed plastic bags. Double-bagging isn't a bad idea, especially for bottles with pump tops or flip caps.
Consider wrapping fragile bottles in bubble wrap or placing them inside shoes or other soft items for cushioning.
Tighten all caps securely.
Step 4: Special Considerations and Exceptions
While the 3-1-1 rule and checked baggage guidelines cover most scenarios, there are important exceptions and special cases to be aware of:
Sub-heading: Medically Necessary Liquids
Exempt from 3-1-1: Medications (liquid or otherwise), infant formula, breast milk, and juice for infants or toddlers are exempt from the 3-1-1 rule. This means you can bring these in quantities larger than 3.4 ounces in your carry-on.
Declare Them! It is crucial to declare these items to the TSA officers at the security checkpoint. They may require additional screening, so having them easily accessible is helpful. You do not need to put them in the quart-sized bag with your other toiletries.
Documentation: While not always required, having a doctor's note or prescription label for medications can expedite the screening process, especially for larger quantities.
Sub-heading: Duty-Free Liquids
Special Rules Apply: If you purchase liquids (like alcohol or perfume) at duty-free shops after you've gone through security at an international airport, they can often be carried onto your connecting flight, even if they exceed 3.4 ounces.
Tamper-Evident Bag and Receipt: The key here is that the liquids must be in a transparent, secure, tamper-evident bag provided by the retailer, and the original receipt must be present and show that the purchase was made within the last 48 hours. Do not open the bag until you are at your final destination! These items will also undergo additional screening.

Sub-heading: Hand Sanitizer
Carry-On: Hand sanitizer falls under the 3-1-1 rule for carry-on bags. So, you can bring travel-sized containers of hand sanitizer (3.4 oz/100 ml or less) in your single quart-sized bag.
Checked Bag: For checked bags, hand sanitizer is subject to the same FAA limits as other restricted medicinal and toiletry articles (total 70 oz/2 L per person, with individual containers not exceeding 17 oz/500 ml).
QuickTip: Revisit posts more than once.
Step 5: Final Tips for a Smooth Security Experience
You're almost an expert! Here are a few last tips to make your trip through airport security with liquids as seamless as possible:
When in Doubt, Check It: If you're unsure whether an item is allowed in your carry-on, or if it exceeds the 3-1-1 limits and isn't an exception, pack it in your checked baggage. It's better to be safe than sorry and avoid having items confiscated.
Arrive Early: Especially if you have a lot of liquids or special items, arriving early at the airport gives you ample time for security screening and any potential questions from TSA officers.
Be Prepared for Screening: Have your quart-sized bag of liquids out of your carry-on and ready to place in a separate bin. If you have medically necessary liquids or infant nourishment, have those ready to declare.
Check Southwest's Website: While these are the general TSA rules that Southwest adheres to, it's always a good practice to double-check Southwest Airlines' official website or the TSA's "What Can I Bring?" tool for the most up-to-date and specific information, especially if you have unusual items.
By following these steps, you'll be well-prepared to breeze through security with all your essential liquids on your next Southwest Airlines flight! Happy travels!
