Oh, planning a trip with Southwest Airlines and wondering about that all-important carry-on? Excellent question! It's one of the most common travel queries, and getting it right can save you a lot of hassle (and potential fees) at the airport. Let's dive deep into Southwest's carry-on policy, with all the nitty-gritty details to ensure your travel experience is as smooth as a fresh bag of pretzels.
The Great Carry-On Conundrum: How Heavy Can It Be?
This is where Southwest Airlines often stands out from other carriers! Unlike many airlines that impose a strict weight limit on carry-on bags, Southwest Airlines does not have a specific weight restriction for your carry-on bag.
Yes, you read that correctly! This is a significant advantage for travelers who tend to pack a bit heavier. However, there's a crucial caveat: you must be able to lift your carry-on bag into the overhead bin unaided. If you can't, it might need to be checked.
So, while there's no number on a scale to worry about for your carry-on, keep in mind that airline staff can still request you check a bag if they deem it too heavy for you to safely stow.

Step 1: Understand the Basics – What's Allowed in the Cabin?
Before we get into the specifics, let's clarify what Southwest allows you to bring onboard. Every ticketed customer on Southwest Airlines is permitted to bring:
One (1) Carry-on Bag: This is the larger item that typically goes in the overhead bin.
One (1) Personal Item: This is a smaller item that must fit under the seat in front of you.
This "one bag plus one personal item" rule is standard across most airlines, but Southwest's lack of a carry-on weight limit sets it apart.
Sub-heading: The Golden Rule of Carry-on
Always remember, the ultimate goal is for your bag to fit and for you to handle it. This is often more important than any hypothetical weight limit.
Step 2: Mastering the Dimensions – Size Matters More Than Weight
While weight is lenient, size is absolutely critical. Your carry-on bag must adhere to specific dimensions to ensure it fits comfortably in the overhead compartments.
Tip: Remember, the small details add value.
Southwest Carry-on Bag Dimensions: Your carry-on bag should not exceed 24 inches (L) x 16 inches (W) x 10 inches (H).
Important Note: These dimensions include wheels, handles, and any other attachments! Many people forget to measure with these extensions, leading to surprises at the gate. Always measure your bag from its longest, widest, and highest points, including all parts that stick out.
Sub-heading: Personal Item Perfection
Your personal item also has specific size requirements, as it needs to fit under the seat in front of you.
Southwest Personal Item Dimensions: Your personal item should not exceed 18.5 inches (L) x 13.5 inches (W) x 8.5 inches (H).
Examples of personal items include a purse, briefcase, laptop bag, small backpack, or a camera bag. Remember, a pet carrier will count as either your carry-on or personal item.
Step 3: Packing Smart – Maximizing Your Space (and Staying Compliant)
Since weight isn't a primary concern for your carry-on, your focus shifts to efficient packing that respects the size limits.
Sub-heading: The Art of Rolling vs. Folding
Many seasoned travelers swear by the rolling method for clothes, claiming it saves space and reduces wrinkles. Experiment to see what works best for your wardrobe.
Consider using packing cubes to compress your clothing and organize your bag, making it easier to fit more while staying within the dimensions.
Sub-heading: Liquids, Gels, and Aerosols: The TSA's 3-1-1 Rule
This rule applies to all airlines operating in the US, including Southwest.
3: All liquids, gels, and aerosols must be in containers of 3.4 ounces (100 milliliters) or less per item.
1: All containers must fit into one (1) quart-sized, clear, sealable bag.
1: Only one such bag is permitted per passenger.
Make sure to pull this bag out of your carry-on before going through security for easier screening.
Sub-heading: Medications and Other Special Items
Medications: Liquid medications, breast milk, and baby formula in quantities larger than 3.4 ounces are generally exempt from the 3-1-1 rule but should be declared to TSA officers.
Assistive Devices: Crutches, walkers, wheelchairs, and other mobility aids do not count towards your carry-on or personal item limit.
Tip: Avoid distractions — stay in the post.
Step 4: At the Airport – Gate Check and Overhead Bin Etiquette
Even if your bag meets the dimensions and you can lift it, there are a few things to keep in mind at the airport.
Sub-heading: The Dreaded Sizer
At the boarding gate, Southwest staff may have a "sizer" – a metal frame designed to confirm your bag fits the allowed dimensions. If your bag doesn't fit, you'll be asked to gate-check it. While Southwest doesn't charge for the first two checked bags, a gate-checked bag can cause delays and inconvenience.
Avoid the stress by measuring your bag accurately at home!

Sub-heading: Boarding and Overhead Bin Space
Southwest Airlines uses a unique open seating policy. This means earlier boarding groups often get first pick of overhead bin space. If you're in a later boarding group, especially on a full flight, overhead space might be limited.
In such cases, flight attendants may ask you to check your carry-on at the gate even if it fits the dimensions, simply due to a lack of available overhead space. This is typically free of charge, but your bag will go with the checked luggage.
Step 5: Prohibited Items – What NOT to Pack in Your Carry-On
Beyond the size and liquid rules, there are certain items that are strictly prohibited in your carry-on for safety and security reasons. This is governed by TSA regulations.
Sub-heading: Common Prohibited Items
Sharp Objects: Knives, box cutters, razor blades (unless contained in a disposable cartridge), and tools with blades longer than 7 inches.
Flammable Items: Lighter fluid, aerosols not classified as toiletries (e.g., spray paint), and fireworks.
Explosives: Any explosive devices or materials.
Firearms: Firearms are not allowed in carry-on bags. They must be declared and properly packed in checked luggage.
Self-Defense Items: Pepper spray, mace, and other similar items are generally prohibited in carry-ons.
Lithium Batteries: Spare lithium batteries (those not installed in a device) must be carried in your carry-on bag. They are not allowed in checked luggage due to fire risk. Electronic smoking devices (e.g., e-cigarettes) also must be in carry-on.
Always check the TSA's "What Can I Bring?" list on their official website if you're unsure about a specific item.
In Conclusion: Travel Light, Travel Smart!
While Southwest Airlines offers a fantastic advantage with no carry-on weight limit, the size restrictions and your ability to lift your bag remain paramount. By understanding these guidelines and packing strategically, you can breeze through security and onto your flight with ease, ready for your Southwest adventure!
