This Samsonite Freeform model stands out as the best overall choice due to its lightweight yet durable hardshell construction, which offers both protection and ease of handling. Its smooth spinner wheels and TSA lock make it highly functional for domestic travel, especially on Southwest Airlines where size and security matter.

For travelers prioritizing dependable, secure, and straightforward luggage, this pick ticks all the boxes.
Pros:- Lightweight and durable hardshell construction
- Smooth-rolling spinner wheels for effortless maneuverability

American Tourister Stratum 2.0 Expandable Hardside Luggage with Spinner Wheels, Carry-On, Jade Green
Compared with the Samsonite Freeform, the American Tourister Stratum 2.0 offers a more affordable yet stylish option, with a textured ABS shell that resists scratches and adds a pop of color. Its spacious interior with multiple compartments makes organization straightforward, but its lighter weight might compromise some durability over time, especially if frequently handled roughly. Its spinner wheels provide smooth maneuverability, similar to the Samsonite, but the overall build isn’t quite as robust. This model makes the most sense for budget-conscious travelers who want a colorful, functional carry-on that still performs well on Southwest Airlines. However, those needing maximum durability might prefer the more premium Samsonite option.
Pros:- Stylish textured ABS shell with metallic sheen
- Smooth spinner wheels for easy handling
- Expandable for additional packing space
- Multiple interior compartments for organization
Cons:- Lighter design may reduce long-term durability

Samsonite Freeform Hardside Carry-On Luggage with Spinner Wheels – Black
This black Samsonite Freeform model emphasizes ease of travel with its lightweight, scratch-resistant polycarbonate shell and ample organizational compartments, making it comparable to the Jade Green version but in a classic color. Its eight spinner wheels offer excellent maneuverability, surpassing the four-wheel setups of some competitors, and the spacious interior with stretchable straps helps keep belongings secure. Unlike the American Tourister, its more refined construction and longer warranty make it better suited for frequent travelers. The main tradeoff is its limited color palette and a shell that, while durable, might feel less forgiving if dropped. This best suits travelers who prioritize durability, organization, and effortless handling.
Pros:- Lightweight with eight spinner wheels for smooth handling

- Spacious interior with organizational compartments

The LEVEL8 Grace offers a lightweight yet sturdy design with its PC+ABS shell, making it easier to carry through busy airports. Its expandable feature provides extra space when needed, though it’s on the smaller side for longer trips—making it perfect for quick getaways or business travel. The dedicated laptop compartment adds a layer of convenience not seen in all competitors, and its smooth 360° spinner wheels ensure easy movement through crowded terminals.

Compared with the Samsonite Freeform, the American Tourister Stratum 3.0 offers a more stylish and expandable option, with a vibrant blue finish and a patented molded hook for hands-free carrying. Its 8 spinner wheels provide effortless mobility, and its expansion feature allows for an additional 1.5 inches of packing space—great for travelers who anticipate last-minute shopping or longer packing lists.

This carry-on stands out for its combination of lightweight design and rugged polycarbonate shell, making it ideal for frequent travelers who value durability. Compared with the Swissgear Sion, it offers a more robust build and a sleek, modern look, but at a higher price point. Its smooth 360° spinner wheels and TSA lock add convenience and security, while the spacious interior with organization features makes packing easier.

Swissgear Sion Softside Expandable Spinner Carry-On Luggage, 21-Inch, Black
The Swissgear Sion Softside Carry-On makes a compelling case for travelers who need a lightweight, flexible option. Its polyester fabric exterior keeps weight down while providing moderate durability, and the expandable capacity adds versatility for packing extra items. Compared with the Away hardside, it is less rigid but more adaptable in tight overhead compartments. Its 360-degree spinner wheels ensure easy mobility, and the 10-year warranty offers peace of mind. The main tradeoff is its limited protection against impacts—so it’s better suited for careful handling rather than rough baggage handling. This model is best for short trips or travelers who prefer softside luggage that can expand when needed, but it may not withstand heavy luggage abuse.
Pros:- Lightweight yet durable polyester fabric
- Expandable capacity for extra packing space
- Smooth 360-degree spinner wheels
- Reliable 10-year warranty
Cons:- Limited color options
- May be small for longer trips

Bottom line: This carry-on is well-suited for travelers who need a lightweight, expandable bag for short trips, with some compromise on impact resistance.
LOVEVOOK 20 Inch Carry On Luggage with TSA Lock, Water-Resistant Softside Suitcase with Spinner Wheels
The LOVEVOOK softside carry-on is designed for travelers who value water resistance and multiple organizational compartments. Its polyester exterior with leather accents offers reliable protection against light rain, making it a good choice for unpredictable weather. Compared with the hard-sided Away, it provides more flexibility and easier to squeeze into tight overhead compartments thanks to its soft sides. The multiple sections and pockets help keep belongings organized, while the spinner wheels ensure smooth mobility. The main tradeoff is that softside luggage can be more vulnerable to rough handling, and the zippers may not be as durable as those on hard cases. This makes it ideal for travelers who prioritize water resistance and flexibility, but less so for those worried about impacts.
Pros:- Water-resistant material for light weather protection
- Multiple compartments and pockets for organization
- Smooth spinner wheels for easy mobility
- Lightweight at just 6.7 pounds
Cons:- Limited color options

UKEIN 3-Piece Luggage Set with Carry-On, Backpack, and Toiletry Bag – Beige
The UKEIN 3-piece set offers a comprehensive solution for travelers who prefer carrying multiple pieces for maximum organization. The 20-inch hardside carry-on, combined with the 18-inch backpack and toiletry bag, covers a wide range of travel needs. Its polycarbonate shell provides solid impact resistance, while the dual spinner wheels and TSA lock add security and ease of movement. Compared to single-piece options like the Away or Swissgear, this set is more versatile but adds weight and bulk, especially with the backpack and toiletry bag.

How We Picked
These luggage options were evaluated based on size compatibility with Southwest Airlines’ strict carry-on policies, weight to prevent extra fees, build quality, ease of maneuverability, and value for price. We prioritized products with reliable spinner wheels and TSA locks for convenience and security. Durability and customer reviews also played a role in ranking, ensuring each pick balances practicality and longevity. The goal was to identify options that suit different traveler needs while meeting airline restrictions, resulting in a clear hierarchy that highlights the best overall, best value, and specialized picks.Factors to Consider When Choosing Best Carry On For Southwest Airlines
Choosing the best carry on for Southwest Airlines involves understanding several key factors. Size and weight are paramount, given their strict cabin luggage limits. Durability matters for frequent travelers, while ease of handling can greatly impact your airport experience. Considering your packing style—whether you prefer softside flexibility or hardside protection—can influence your choice. Additionally, features like expandability, TSA locks, and water resistance add practical value. Being aware of common pitfalls such as exceeding size limits or choosing overly heavy luggage can save you money and frustration in the long run.Size and Weight Restrictions
Southwest Airlines enforces specific size limits for carry-on luggage—typically 10 x 16 x 24 inches—and a weight limit of around 40 pounds. It’s crucial to verify your luggage dimensions before purchasing, as exceeding these can lead to additional fees or gate checks. Lighter luggage helps maximize your packing capacity without risking overweight charges. Choosing a bag that comfortably fits within these dimensions saves time and reduces the hassle during boarding. Always double-check airline policies as they can update restrictions seasonally or due to operational needs.
Durability and Build Quality
Durability varies widely among options, with hardside models generally offering better protection against impacts and rough handling. However, high-quality softside luggage provides flexibility and easier packing, especially if you need to squeeze your bag into tight spaces. Investing in sturdy materials like polycarbonate or ballistic nylon can extend your luggage’s lifespan, especially for frequent flyers. Keep in mind that cheaper options might save money upfront but may not withstand frequent travel wear and tear. Balancing durability with weight is key—heavier materials could eat into your allowed weight limit.
Maneuverability and Ease of Use
Spinner wheels and ergonomic handles make a significant difference in navigating busy airports or tight spaces. Swiveling wheels that spin smoothly reduce fatigue during long walks or when maneuvering through crowded terminals. Consider the overall weight of the luggage itself—lighter models are easier to carry or roll around. A well-designed handle that extends comfortably to your height improves handling and reduces strain. Avoid overly bulky or poorly balanced bags, which can hinder quick gate changes or tight storage compartments.
Additional Features and Practicality
Features like TSA-approved locks, water resistance, and expandability add real convenience. TSA locks prevent unauthorized access while simplifying security checks. Water resistance can protect your belongings from rain or spills, especially in softside models. Expandable luggage offers extra packing space when needed but can add weight and size. Consider your travel style—if you often fly with minimal packing, a compact, lightweight bag makes sense; for longer trips, an expandable model might be worth the tradeoff. Beware of bags with complicated zippers or fragile wheels that may break under stress.
Price and Long-Term Value
Higher-priced luggage often offers better durability, lighter weight, and more features, making it cost-effective over time. Cheaper options can be appealing upfront but may need replacement sooner, especially if you travel frequently. Think about how often you’ll use the luggage and whether investing in a premium model aligns with your travel habits. Look for warranties or customer service reputation, as quality assurance can save money and frustration later. Balancing initial cost with expected lifespan will help you find the best value for your specific needs.
Frequently Asked Questions
Can I bring a larger carry-on bag on Southwest Airlines?
Southwest Airlines strictly enforces size limits for carry-on luggage, typically 10 x 16 x 24 inches. While some bags slightly larger than this may be allowed if they fit in the overhead bin, it’s risky and can lead to gate checks or fees. To avoid surprises, always measure your luggage beforehand and opt for models designed to meet these restrictions. Choosing a bag with a flexible or expandable softside design can help if you’re close to the limit, but staying within the specified dimensions remains the safest approach.
Is a hardside or softside carry-on better for Southwest flights?
Hardside luggage tends to offer better impact protection, making it ideal for fragile items or rough handling. Softside bags, however, provide greater flexibility, allowing you to squeeze into tight storage spaces and often weigh less. For Southwest flights, where size restrictions are strict, softside luggage can be advantageous if you need a little extra room or flexibility. The choice ultimately depends on your travel habits—if durability and protection are priorities, go for hardside; if convenience and packing ease matter more, softside may be the better fit.
Should I prioritize weight or durability when choosing a carry-on?
Both matter, but for Southwest Airlines, weight often takes precedence because exceeding the airline’s weight limit incurs fees or gate-checking. Lighter luggage helps you maximize packing capacity without risking oversize or overweight penalties. That said, durability shouldn’t be sacrificed entirely; a lightweight, high-quality bag made from tough materials offers a good compromise. Carefully balancing these factors ensures your luggage remains functional over many trips while keeping within airline restrictions.
Are expandable carry-ons worth the extra size and weight?
Expandable carry-ons provide additional packing space when needed, which can be handy for longer trips or last-minute shopping. However, they tend to be slightly heavier and larger when expanded, risking surpassing size or weight limits. For frequent travelers who often need the extra room, the convenience outweighs the tradeoff. Conversely, if you prefer simplicity and minimal packing, a non-expandable bag that stays within strict dimensions might be more suitable to avoid any risk of extra fees.
What features should I look for in a carry-on for frequent Southwest flyers?
Frequent flyers should prioritize durability, lightweight construction, and ease of mobility. Features like smooth spinner wheels, telescoping handles, TSA locks, and water resistance add practical value. A bag with reliable wheels and handles reduces fatigue during airport transfers, while TSA locks streamline security checks. Long-term durability is also important—investing in quality materials ensures your luggage withstands frequent trips. Balancing these features with your budget can help you find a carry-on that improves your travel experience over time.
Conclusion
For those seeking the best overall, the Samsonite Freeform offers a durable, lightweight, and reliable choice that suits most travelers. Budget-conscious flyers will appreciate the American Tourister Stratum 2.0 for its affordability and expandability. If you prefer premium features and sleek design, the Away Carry-On provides a stylish, TSA-locked hardside with excellent maneuverability. Beginners or infrequent travelers might opt for softside options like LOVEVOOK for flexibility, while frequent flyers should invest in durable, high-quality luggage with advanced features. Tailor your choice to your specific travel habits to make the most of your gear.
