Flying with Southwest Airlines is known for its relatively straightforward and passenger-friendly policies, especially when it comes to baggage. However, understanding the exact dimensions and rules for carry-on luggage can still be a bit tricky. So, let's break it down in a comprehensive, step-by-step guide to ensure your carry-on glides smoothly into the overhead bin, saving you time, stress, and potential fees!

Step 1: Unpacking the Basics – What's a Carry-On vs. a Personal Item?
Before we even talk about numbers, let's clarify the two types of bags you can bring onboard with Southwest Airlines. This is often where the confusion begins!
-
The Carry-On Bag: This is your primary piece of hand luggage. It's designed to fit in the overhead bin above your seat. Think small suitcases, roller bags, or larger duffel bags. This is the bag that has strict size limits.
-
The Personal Item: This is your secondary, smaller bag. It's intended to fit under the seat in front of you. Examples include purses, briefcases, laptop bags, small backpacks, or even a pillow. While smaller, it also has its own set of dimensions to adhere to.
Why is this distinction important? Because exceeding the size for either can lead to your bag being gate-checked, which can be inconvenient and, in some cases, incur fees if it then exceeds checked baggage limits.
Step 2: Measuring Up – The Official Southwest Carry-On Dimensions
Now for the crucial numbers! Southwest Airlines has very specific maximum dimensions for both your carry-on and personal item. It's essential to measure your bags accurately, including any wheels, handles, and external pockets.
Tip: Reread complex ideas to fully understand them.
Sub-heading: Your Main Carry-On Bag
For your main carry-on bag, the maximum allowed dimensions are:
-
Length: 24 inches (61 cm)
-
Width: 16 inches (40 cm)
-
Height: 10 inches (25 cm)
Remember: This is a length + width + height measurement, including all protrusions. A common mistake is to measure only the main body of the bag and forget the wheels or handles, which can push you over the limit.
Sub-heading: Your Personal Item
Your personal item needs to be smaller, fitting snugly under the seat in front of you. The recommended maximum dimensions are:
-
Length: 18.5 inches (47 cm)
-
Width: 8.5 inches (22 cm)
-
Height: 13.5 inches (34 cm)
Pro-Tip: While these are the official guidelines, flexibility is key for personal items. A soft-sided backpack is often more forgiving than a rigid laptop case if you're trying to maximize space under the seat.
Step 3: The Fit Test – Using the Sizer Bins
QuickTip: Skip distractions — focus on the words.
At the airport, Southwest, like many airlines, provides sizer bins at the check-in counter and often near the gate. These metal frames are your ultimate test.
-
What they are: The sizer bins are designed to perfectly match the maximum allowed dimensions for carry-on bags.
-
How they work: You simply place your carry-on bag into the sizer. If it slides in easily without forcing, you're good to go! If it doesn't fit, or if you have to force it, your bag is too large and will likely need to be checked.
-
Don't try to cheat the sizer! Airport staff are experienced and will spot oversized bags. It's much better to realize your bag is too big before you get to the gate and cause delays for yourself and others.
Step 4: Weighting Your Options – Is There a Weight Limit?
This is where Southwest often stands out. Unlike many other airlines, Southwest Airlines generally does not impose a specific weight limit for carry-on bags, as long as they fit within the stated dimensions and you can safely lift them into the overhead bin yourself.
-
However, common sense prevails. If your bag is so heavy that you struggle to lift it, or if it appears excessively bulky, a flight attendant might ask you to gate-check it for safety reasons. It's always best to pack reasonably.
Step 5: Packing Smart – Maximizing Your Carry-On Space
Even with strict dimensions, clever packing can make a huge difference.
-
Roll, don't fold: Rolling your clothes often saves space and minimizes wrinkles.
-
Utilize packing cubes: These can compress your clothes and organize your bag efficiently.
-
Wear your bulkiest items: If you have a heavy coat or bulky shoes, wear them on the plane rather than packing them.
-
Minimize liquids: Remember the TSA 3-1-1 rule for liquids in your carry-on: containers must be 3.4 ounces (100 milliliters) or less, fit in one quart-sized bag, and be limited to one bag per passenger.
-
Think about your "personal item" as an extension: Use your personal item for things you'll need during the flight, like snacks, entertainment, and important documents.
Step 6: Special Circumstances – What About Other Items?
Southwest is quite accommodating with certain special items, but it's crucial to understand how they count towards your carry-on allowance.
Tip: Reflect on what you just read.
Sub-heading: Pet Carriers
-
If you're traveling with a small, vaccinated domestic cat or dog, their pet carrier will count as either your carry-on bag or your personal item.
-
The carrier must fit under the seat in front of you. You'll also need to pay a pet fare.
Sub-heading: Musical Instruments
-
Smaller musical instruments that meet the standard carry-on dimensions (24" L + 16" W + 10" H) can be brought onboard as your carry-on item if there's space.
-
Larger instruments may be carried onboard if they fit in an overhead bin or under a seat and there is space available.
-
For instruments that don't fit, you might be able to purchase a separate seat for them.
-
Always check Southwest's specific policy for musical instruments, as rules can be detailed and vary by instrument type.
Sub-heading: Car Seats and Strollers
-
Southwest allows you to check one stroller and one car seat/child restraint system free of charge per ticketed Customer, in addition to your standard baggage allowance. These do not count towards your carry-on or personal item allowance if checked.
-
If you plan to bring a car seat onboard for use by a ticketed child, it must meet FAA approval and fit securely in the aircraft seat.
Step 7: The "Why" Behind the Rules – Understanding the Importance of Compliance
It might seem like a lot of rules, but there are good reasons why airlines enforce carry-on size limits:
-
Safety: Overstuffed overhead bins can be dangerous, as bags can fall out during turbulence or unexpected stops.
-
Space: There's limited space in the cabin. Adhering to limits ensures everyone has a spot for their bag.
-
Boarding Efficiency: When passengers adhere to carry-on rules, boarding and deplaning are much smoother and faster for everyone.
-
Fairness: It ensures that all passengers have an equal opportunity to bring their carry-on items onboard.
By following these steps, you'll be well-prepared to breeze through the airport with your Southwest Airlines carry-on, enjoying a stress-free journey!

How to travel with a pet carrier as a carry-on on Southwest? Your pet carrier counts as either your carry-on or personal item. It must fit under the seat in front of you, and you'll need to pay the applicable pet fare at the airport. Call Southwest in advance to make a reservation for your pet as space is limited.
How to bring a musical instrument as a carry-on on Southwest? If your instrument (including its case) is within the standard 24" L + 16" W + 10" H carry-on dimensions, you can bring it onboard if space is available. Larger instruments may also be allowed if they fit in the overhead bin or under a seat, or you can purchase a separate seat for them if they don't fit otherwise.

How to confirm the most up-to-date carry-on policy for Southwest? Always check the official Southwest Airlines website's "Carryon and Personal Item Policy" page or contact their customer service directly, as policies can occasionally be updated.
How to deal with an oversized carry-on at the Southwest gate? If your bag is deemed oversized at the gate, you will be required to gate-check it. Depending on the size and weight, and if you've already utilized your free checked bags, you may incur additional checked baggage fees.
How to use the sizer bin effectively at the airport for Southwest? Place your bag into the sizer with the widest side first. If it slides in easily without forcing, and without bulging out, it meets the requirements. If you have to push or cram it in, it's likely too large.
