Have you ever stood in the airport security line, frantically trying to cram your full-sized shampoo bottle into a tiny plastic bag, only to have a TSA agent shake their head? It's a common travel headache! When flying with Southwest Airlines, like all airlines operating in the US, you'll need to adhere to the Transportation Security Administration (TSA) guidelines for carrying liquids in your carry-on luggage.
This guide will break down exactly how many ounces of liquid you can carry on Southwest Airlines, ensuring a smooth and stress-free journey.
Understanding the 3-1-1 Rule: Your Liquid Carry-On Mantra
The cornerstone of liquid carry-on regulations is the TSA's 3-1-1 Rule. This rule applies to all liquids, aerosols, gels, creams, and pastes you wish to bring in your carry-on bag. Southwest Airlines, like all U.S. carriers, follows these federal regulations.
Here's what each number in 3-1-1 stands for:
3 stands for 3.4 ounces (or 100 milliliters). This is the maximum size for each individual liquid container.
1 stands for 1 quart-sized bag. All your 3.4-ounce or smaller containers must fit comfortably into one transparent, re-sealable, quart-sized plastic bag.
1 stands for one bag per passenger. Each traveler is limited to a single quart-sized bag of liquids.
Let's dive into the specifics of navigating this rule.

| How Many Ounces Of Liquid Can You Carry On Southwest Airlines |
Step 1: Gather Your Liquid Essentials and Their Sizes
Before you even think about packing, the first step is to identify all the liquid, aerosol, gel, cream, and paste items you intend to bring in your carry-on. This includes everything from toothpaste and shampoo to hand sanitizer and liquid makeup.
What Counts as a Liquid?
It's not just obvious liquids! The TSA defines "liquids" broadly. Consider these common items:
Beverages: Water, juice, soda, coffee, tea, alcohol (within limits, discussed later).
Toiletries: Shampoo, conditioner, lotion, liquid soap, body wash, hairspray, deodorant (gel or spray), toothpaste, mouthwash.
Cosmetics: Liquid foundation, mascara, liquid eyeliner, lip gloss, nail polish, perfume.
Food Items: Yogurt, sauces, dressings, dips, jam, honey.
Other: Contact lens solution, hand sanitizer, bug spray, shaving cream.
Checking Container Sizes
Now, carefully inspect the labels of all these items. The most crucial part of the 3-1-1 rule is the container size.
Look for the label: Every container of liquid, gel, or aerosol should clearly state its volume in ounces (oz) or milliliters (ml).
The 3.4-ounce limit: No single container can exceed 3.4 ounces (100 milliliters). Even if you have a larger bottle that's mostly empty, if its original capacity is over 3.4 ounces, it's not allowed in your carry-on. You'll need to transfer the contents to smaller, compliant travel-sized containers.
QuickTip: Scan for summary-style sentences.
Step 2: Acquire a Quart-Sized, Transparent, Re-sealable Bag
This seemingly simple bag is a critical component of the 3-1-1 rule. Don't underestimate its importance!
The Right Bag for the Job
Quart-sized: This typically measures approximately 7 inches by 8 inches (or 17.78 cm by 20.32 cm).
Transparent: It must be clear so TSA agents can easily see the contents without having to open it.
Re-sealable: A zipper-top bag (like a Ziploc bag) is ideal as it can be securely closed.
Pro Tip: While any clear, quart-sized, re-sealable bag will do, many travel stores sell specific "TSA-approved" toiletry bags that are perfectly sized and designed for this purpose.
Step 3: Fit All Your Compliant Liquids into the Quart Bag
This is where the puzzle-solving begins!
The "Fit Comfortably" Clause
All your individual liquid containers (each 3.4 ounces or less) must fit comfortably within the single quart-sized bag. This means:
No forcing: The bag should close easily without straining the zipper or bulging excessively. If you have to fight to close it, you probably have too many items or items that are too bulky.
One bag per person: Remember, only one quart-sized bag is allowed per passenger. You can't have multiple bags, even if they're all small.
Strategizing Your Packing
Prioritize: Decide which liquid essentials are absolutely necessary for your carry-on. Can some items be purchased at your destination or packed in checked luggage?
Travel-sized versions: Invest in travel-sized versions of your favorite products. Many brands offer mini shampoos, conditioners, lotions, and more.
Solid alternatives: Consider solid alternatives where possible! Think shampoo bars, solid deodorant, toothpaste tablets, and makeup wipes. These don't fall under the 3-1-1 rule and can save valuable space in your liquid bag.
Step 4: Prepare for Security Screening
When you reach the airport security checkpoint, the 3-1-1 bag needs to be easily accessible.
Tip: Reread key phrases to strengthen memory.
Removing the Bag for Screening
Separate and Present: You are required to remove your quart-sized bag of liquids from your carry-on luggage and place it in a separate bin for X-ray screening. This allows security personnel to inspect the contents clearly.
Don't bury it: Avoid burying your liquid bag at the bottom of your carry-on. Keep it in an easily accessible outer pocket or on top of your other belongings for a smoother security experience.
Step 5: Understanding Exemptions and Special Considerations
While the 3-1-1 rule is generally strict, there are important exemptions and special considerations, particularly for medical necessities and infant care. Southwest Airlines adheres to these TSA exemptions.

Medical Necessities
Larger quantities allowed: Liquid medications, medically necessary gels, and certain medical devices (like CPAP machines and their distilled water) are generally allowed in quantities larger than 3.4 ounces.
Declaration is key: You must declare these items to a TSA officer at the checkpoint. They may require additional screening, such as asking you to open containers or perform a pat-down.
Doctor's note (recommended, not always required): While not always mandatory, having a doctor's note or prescription for your liquid medications can expedite the screening process and provide clarity to TSA officers, especially for less common items.
Infant and Child Nourishment
Formula, breast milk, and juice: These are also exempt from the 3-1-1 rule in reasonable quantities.
Declaration: As with medical items, you must declare these to a TSA officer for inspection.
Screening process: They may be subject to additional screening, including being asked to open the containers or pour a small amount into a separate container for testing.
Duty-Free Liquids (International Travel)
If you purchase duty-free liquids (like alcohol or perfume) internationally and are traveling to the United States with a connecting flight, they can be carried in your carry-on if:
They are packed in a transparent, secure, tamper-evident bag by the retailer.
The bag shows no signs of tampering when presented to TSA for screening.
The original receipt for the liquids is present and the purchase was made within 48 hours.
Recommendation: Even with these rules, it's often best to pack duty-free liquids in your checked baggage if possible to avoid potential issues, as specific airport rules can vary.
Liquids in Checked Baggage with Southwest Airlines
Here's the good news: There are no size restrictions for individual liquid containers in your checked baggage with Southwest Airlines!
You can pack full-sized shampoos, lotions, and any other liquids you desire in your checked bags. However, it's always wise to:
Seal them securely: Use sturdy, leak-proof containers.
Double-bag them: Place liquids in sealed plastic bags (like Ziploc bags) within your checked luggage to prevent spills and protect your other belongings.
Alcohol limits: If you're checking alcohol, remember there are quantity and alcohol content limits. Generally, alcoholic beverages between 24% and 70% alcohol by volume are limited to 5 liters (1.3 gallons) per passenger. Anything over 70% alcohol by volume is typically prohibited.
Conclusion: A Smooth Liquid Journey with Southwest
Tip: Look out for transitions like ‘however’ or ‘but’.
By following these simple, yet crucial, guidelines, you can navigate the liquid restrictions for your Southwest Airlines carry-on with ease. Remember the 3-1-1 rule: 3.4-ounce containers, 1 quart-sized bag, 1 bag per passenger. Always separate your liquid bag for security screening, and don't hesitate to declare any medical or infant-related liquid exemptions. Happy travels!
