Ever found yourself at the airport, frantically trying to figure out if your perfectly packed carry-on meets the airline's requirements? Don't worry, you're not alone! When it comes to flying with Southwest Airlines, understanding their carry-on policy is key to a smooth and stress-free journey. Let's dive in and demystify exactly how many carry-on bags you can bring, along with all the essential details you need to know.
Southwest Airlines, known for its "Bags Fly Free" policy (for checked luggage), also has a clear and straightforward approach to carry-on items. Unlike some airlines that have complex tiers or weight limits for carry-ons, Southwest keeps it relatively simple.

| How Many Carry On Bags Can You Bring On Southwest Airlines |
Step 1: Engage with the Policy – What's the Basic Rule?
Before we get into the nitty-gritty, let's start with the fundamental question: How many carry-on bags can you bring on Southwest Airlines?
The answer is simple: You are allowed one (1) carry-on bag AND one (1) personal item.
Sounds easy, right? Now, let's break down what each of those means and what you need to keep in mind.
Step 2: Understanding Your "One Carry-On Bag"
Your main carry-on bag is designed to fit in the overhead bin. This is typically your small suitcase, roller bag, or duffel bag.
Dimensions are Key!
Southwest has specific size limits for your carry-on bag. It's crucial to adhere to these dimensions to avoid any issues at the gate.
-
Maximum Dimensions: Your carry-on bag (including wheels, handles, and any attachments) must not exceed:
-
24 inches (L)
-
16 inches (W)
-
10 inches (H)
It's always a good idea to measure your bag before you leave for the airport. Many luggage manufacturers provide these dimensions, but a quick home measurement with a tape measure can give you peace of mind.
-
What Fits in the Overhead Bin?
This category typically includes:
Tip: Train your eye to catch repeated ideas.
-
Small suitcases
-
Roller bags
-
Small duffel bags
-
Smaller backpacks that are more structured and might not fit under the seat
Step 3: Getting to Know Your "One Personal Item"
In addition to your main carry-on, you get to bring a personal item. This item is designed to fit under the seat in front of you.
Personal Item Dimensions
While there's a little more flexibility here than with the carry-on, there are still recommended dimensions to ensure it fits comfortably:
-
Recommended Dimensions: Your personal item should generally not exceed:
-
18.5 inches (L)
-
8.5 inches (W)
-
13.5 inches (H)
Think about bags that are compact enough to slide under a standard airline seat.
-
Examples of Personal Items
This category is for smaller, more essential items you want to keep easily accessible during your flight. Common examples include:
-
Purses (including crossbody bags)
-
Briefcases
-
Laptop computer cases
-
Small backpacks (the kind that aren't overly bulky)
-
Diaper bags
-
Small cameras
-
Pillows (though neck pillows don't typically count towards your limit)
-
Blankets
Step 4: Special Circumstances & Exemptions – What Doesn't Count?
Southwest is quite accommodating when it comes to certain items that are essential for travel, and these do not count toward your one carry-on and one personal item limit. This is where many people can strategically pack more without incurring extra fees or hassle.
Medical and Mobility Devices:
-
Assistive devices and mobility aids: This includes wheelchairs, crutches, canes, walkers, and other similar aids.
-
Medication and medical supplies: It's highly recommended to keep all your essential medications in your carry-on or personal item. If packed separately for a disability-related need, they do not count towards your bag limits. Needles and syringes for medication are also permitted if packed with the necessary medication.
-
Portable Oxygen Concentrators (POCs) and other breathing aids: These are allowed on board, provided they meet specific requirements and you have the necessary documentation.
Items for Children:
-
Child restraint systems/car seats: If you've purchased a seat for your child and plan to use an FAA-approved child restraint system during the flight, it can be carried on and will not count against your carry-on limit.
-
Strollers: You can check one stroller free of charge, either at the curb, ticket counter, or gate. It does not count as a carry-on item.
-
Diaper bags: As mentioned, these typically fall under the personal item category and are generally allowed.
-
Breast pumps and breast milk: These are permitted and do not count toward your carry-on limits.
Tip: Avoid distractions — stay in the post.
Other Common Exemptions:
-
Outer garments: Coats, jackets, and wraps are generally allowed in addition to your bags.
-
Umbrellas or walking canes: These are also usually exempt.
-
Food for consumption during the flight: If it's in disposable packaging, it's typically allowed in addition to your carry-on allowance.
-
Duty-free merchandise: Items purchased at the airport after security are generally allowed on board, though it's always wise to consolidate them with your personal item if possible.

Step 5: Pets as Carry-Ons: A Special Consideration
Traveling with your furry friend on Southwest? It's possible, but there's a specific rule to remember:
-
Pet carriers count as either your one carry-on item or your one personal item. They do not get a separate allowance.
-
Pets must be small vaccinated domestic cats or dogs, at least 8 weeks old, and must remain in their carrier under the seat in front of you for the entire flight.
-
There's a fee for bringing a pet, and space is limited per flight, so making a reservation for your pet in advance is highly recommended.
Step 6: What if Your Carry-On is Too Big or There's No Space?
Even if your bag meets the dimensions, there are times when it might need to be gate-checked.
-
Full Overhead Bins: On a full flight, overhead bin space can become limited. If this happens, flight attendants may ask volunteers to gate-check their carry-on bags. If there aren't enough volunteers, bags may be required to be gate-checked.
-
Gate-Checking: If your bag is gate-checked, it means it will be tagged and placed in the cargo hold, and you'll typically retrieve it at baggage claim upon arrival at your destination. Always remove any valuables, medications, or essential items before gate-checking your bag.
Step 7: Packing Smart – Tips for Maximizing Your Carry-On Space
Since you're limited to one carry-on and one personal item, intelligent packing is your best friend.
-
Roll Your Clothes: Rolling items tightly saves space and can help prevent wrinkles.
-
Utilize Packing Cubes: These can compress your clothes and keep your bag organized, making it easier to find what you need.
-
Wear Your Bulkiest Items: If you have a heavy jacket or bulky shoes, wear them on the plane instead of packing them.
-
Travel-Sized Toiletries: Adhere to the TSA's 3-1-1 rule for liquids (3.4 ounces or less per container, in a 1-quart-sized bag, one bag per passenger).
-
Leverage Your Personal Item: This is where you put your in-flight entertainment, snacks, medications, and anything you'll need during the flight.
Step 8: Security Checkpoints – Knowing the Rules
Remember that TSA (Transportation Security Administration) rules for what can go in carry-on bags apply to all airlines, including Southwest.
-
Liquids, Gels, Aerosols (3-1-1 Rule): As mentioned, containers must be 3.4 ounces (100 milliliters) or less, fit in one quart-sized clear, sealable bag, and be limited to one bag per passenger.
-
Electronics: Laptops and larger electronic devices generally need to be removed from your bag and placed in a separate bin for X-ray screening.
-
Prohibited Items: Familiarize yourself with the TSA's list of prohibited items (e.g., certain sharp objects, flammable materials, some self-defense sprays). Check the TSA website for the most up-to-date information.
Step 9: International Travel with Southwest (and Partners)
While Southwest primarily operates within the United States, they do offer some international routes. If your itinerary involves a partner airline, be aware that their carry-on policies might differ. Always double-check the baggage policies of any connecting or partner airlines to avoid surprises.
Tip: Read aloud to improve understanding.
Step 10: Final Checklist Before You Fly
Before you head to the airport, a quick review can save you time and stress:
-
Measure your bags: Are they within Southwest's carry-on and personal item dimensions?
-
Weigh your bags (optional, but good practice): While Southwest doesn't have a weight limit for carry-ons, an overly heavy bag can be difficult to lift into the overhead bin.
-
Consolidate liquids: Is your 3-1-1 bag ready for security?
-
Remove prohibited items: Are there any items in your bags that aren't allowed?
-
Keep essentials accessible: Medications, important documents, and valuables should be in your personal item.
By following these steps, you'll be well-prepared to breeze through the airport and enjoy your flight on Southwest Airlines with your carry-on bags. Happy travels!
