Ever stood at airport security, quart-sized bag in hand, wondering if your favorite shampoo is about to be confiscated? You're not alone! The rules around liquids in carry-on bags can be confusing, especially with various airline policies. But when it comes to Southwest Airlines, the good news is they largely follow the standard Transportation Security Administration (TSA) guidelines. Let's break down exactly how much liquid you can bring on your next Southwest flight, step-by-step, to ensure a smooth and stress-free journey!
Navigating the Liquid Landscape: Your Guide to Southwest Flights
Understanding liquid allowances is crucial for efficient packing and avoiding delays at security. While Southwest doesn't have unique liquid restrictions beyond the TSA, knowing the specifics for both carry-on and checked bags is key.

| How Much Liquid Can You Bring On Southwest Airlines |
Step 1: Engage with the "3-1-1 Rule" - Your Carry-On Liquid Mantra!
Before we dive into the specifics, let's get acquainted with the golden rule for liquids in your carry-on bag: the 3-1-1 Rule. Have you heard of it before? It's the most important guideline to remember for a smooth security experience!
The 3-1-1 Rule means:
3.4 ounces (100 milliliters): Each liquid, aerosol, gel, cream, and paste must be in containers of 3.4 ounces (100 milliliters) or less. Look for the size printed on the bottle!
1 quart-sized bag: All of these containers must fit into one transparent, quart-sized (approximately 1-liter) bag. Think of a Ziploc bag that's about 7 inches by 8 inches.
1 bag per passenger: You are limited to one such quart-sized bag per passenger.
So, imagine you're packing your toiletries. That full-size conditioner? It's a no-go for your carry-on. But a travel-sized version, along with your toothpaste and hand lotion, all neatly tucked into that single quart-sized bag, is perfectly fine!
Why the 3-1-1 Rule?
This rule was implemented for security reasons, making it easier for TSA officers to screen liquids and identify potential threats. While it might seem like a hassle, it's designed to keep everyone safe.
What Counts as a Liquid?
It's not just water! The TSA defines "liquids" broadly to include:
Gels: hair gel, deodorant sticks (gel), hand sanitizer (gel)
Aerosols: hairspray, shaving cream, spray deodorant
Creams: lotions, sunscreens, moisturizers
Pastes: toothpaste, peanut butter, mascara (thick paste)
Liquids (of course!): water, juice, perfume, liquid makeup, cough syrup
If you can pour it, spread it, spray it, or pump it, it likely falls under the 3-1-1 rule. When in doubt, assume it's a liquid!
Tip: Don’t rush — enjoy the read.
Step 2: Mastering Your Carry-On Liquids for Southwest Flights
Southwest Airlines, like all U.S. airlines, strictly adheres to the TSA's 3-1-1 rule for carry-on bags. This means there are no special exceptions or additional allowances from Southwest directly for general liquids.
Sub-heading: Packing Your Quart-Sized Bag
Choose the Right Bag: Opt for a clear, resealable, quart-sized plastic bag. Ziploc bags are perfect for this.
Maximize Space: Lay your items flat, and try to fit as many eligible containers as possible without overstuffing the bag. Remember, it needs to be able to close completely.
Keep it Accessible: When going through security, you'll need to remove this bag from your carry-on and place it in a separate bin for screening. Keeping it in an easily accessible outer pocket of your bag will save you time and hassle.
Sub-heading: Onboard Purchases and Exceptions
Duty-Free Liquids: If you purchase duty-free liquids after clearing security at an international airport, you can generally carry them on board even if they exceed 3.4 ounces, provided they are in a secure, tamper-evident bag with the original receipt and were purchased within the last 48 hours. These will still be subject to screening.
Liquids Purchased Post-Security: Any beverages or other liquid items purchased after passing through the security checkpoint within the airport are generally allowed on board without size restrictions. So, feel free to grab that large coffee or water bottle for your flight!
Step 3: Understanding Liquids in Checked Baggage
This is where the rules become much more flexible! For liquids in your checked baggage on Southwest Airlines, you are generally allowed to pack larger quantities.
Sub-heading: General Liquid Allowance in Checked Bags
There are no 3.4-ounce limitations for liquids in checked baggage. You can pack your full-sized shampoo, conditioner, lotions, and other toiletries without worry.
While there are no specific volume limits per item for most liquids, the total aggregate quantity of restricted medicinal and toiletry articles (including aerosols) is limited by the FAA to 2 kg (70 ounces) or 2 L (68 fluid ounces) per person, with each container not exceeding 0.5 kg (18 ounces) or 500 ml (17 fluid ounces). This mostly applies to highly flammable aerosols, so for most toiletries, you're usually fine.
Pack Securely: Always make sure your liquid containers are tightly sealed to prevent leaks. Placing them in separate sealed bags within your checked luggage can offer an extra layer of protection against spills. No one wants a suitcase full of shampoo-soaked clothes!
Sub-heading: Special Considerations for Certain Liquids in Checked Baggage
Alcohol: You can bring alcoholic beverages in your checked baggage, but there are regulations.
Alcoholic beverages with less than 24% alcohol by volume (e.g., most beers and wines) are not restricted in checked bags.
Alcoholic beverages with 24% to 70% alcohol by volume are limited to 5 liters (1.3 gallons) per passenger and must be in unopened retail packaging.
Alcoholic beverages with more than 70% alcohol by volume (e.g., grain alcohol, 151 proof rum) are prohibited in both carry-on and checked bags.
Flammable Liquids: Highly flammable liquids like lighter fluid, paints, or certain cleaning products are generally prohibited in both carry-on and checked baggage due to hazardous material regulations. Always check the TSA's "What Can I Bring?" tool if you're unsure.
Step 4: Navigating Exemptions: When the 3-1-1 Rule Doesn't Apply
While the 3-1-1 rule is strict, there are important exceptions for certain essential liquids. Southwest Airlines, again, follows TSA guidelines on these.
Tip: Reading with intent makes content stick.
Sub-heading: Medications
Allowed in Larger Quantities: Essential medications (prescription and over-the-counter) are exempt from the 3-1-1 rule. This includes liquid medications, gels, and aerosols, even if they are larger than 3.4 ounces.
Declaration and Screening: You should declare these items to a TSA officer at the security checkpoint for inspection.
Medical Documentation (Recommended): While not always required, it's a good idea to travel with supporting documentation for your medication, such as a doctor's note or the prescription label, especially for controlled substances or large quantities.
Keep Them Accessible: If you need access to your medication during the flight, always pack it in your carry-on bag. Southwest recommends bringing all medication in your carry-on or personal item.

Sub-heading: Infant and Child Nourishment
Allowed in Larger Quantities: Formula, breast milk, toddler drinks, and baby/toddler food (including puree pouches) are exempt from the 3-1-1 rule.
Reasonable Quantities: You can bring these items in "reasonable quantities" for your journey.
Declaration and Screening: Similar to medications, these items should be declared to a TSA officer for separate screening. You may be asked to open the containers for inspection.
Cooling: If you need to keep these items cool, ice packs, gel packs, and frozen breast milk/formula are also permitted. If ice or gel packs are partially melted or have any liquid at the bottom of the container, they will be subject to the 3-1-1 rule.
Step 5: Special Cases and General Tips
Sub-heading: Hand Sanitizer
Hand sanitizer falls under the 3-1-1 rule for carry-on bags (3.4 ounces or less, in the quart-sized bag).
However, the FAA has a special exception for one container of liquid hand sanitizer up to 12 ounces per passenger in carry-on bags. This specific item does not need to be in the quart-sized bag. This exception was put in place during the pandemic and remains.
Any additional hand sanitizer beyond the 12-ounce container would need to follow the 3-1-1 rule.
Sub-heading: Traveling with Pets
If you're flying with a small pet in the cabin on Southwest (pet carrier counts as your personal item or carry-on), any water or liquid food for your pet must also adhere to the 3-1-1 rule for carry-on. You can, of course, bring larger quantities in checked baggage.
Sub-heading: TSA PreCheck and Liquids
While TSA PreCheck generally offers expedited screening, the 3-1-1 rule for liquids still applies. The main difference is that you typically do not need to remove your liquids bag from your carry-on when going through the PreCheck lane. This saves you time and effort!
Sub-heading: Tips for a Seamless Security Experience
Tip: Absorb, don’t just glance.
Be Prepared: Have your quart-sized bag of liquids ready to remove from your carry-on as you approach the security checkpoint.
Declare Exceptions: Clearly state to the TSA officer if you have liquid medications, breast milk, or formula that exceed the 3.4-ounce limit.
Double-Check: Before heading to the airport, do a quick check of your bags to ensure no large liquids are accidentally in your carry-on.
Remember:
TSA is the ultimate authority: While Southwest Airlines follows these rules, the final say on what passes through security rests with the TSA officers.
Rules can change: While the 3-1-1 rule has been in place for a long time, it's always a good idea to quickly check the official TSA website before you fly for any last-minute updates or specific item queries.
By following these guidelines, you'll be well-prepared for your Southwest Airlines flight and can breeze through security with confidence! Happy travels!
