For a carry-on for Southwest Airlines, my best overall pick is the Wrangler 22-inch Hardside Spinner, which pairs a familiar suitcase format with spinner wheels; the LOVEVOOK 40L Backpack with Garment Bag suits travelers who want organized, flexible packing, while the TPRC 15-inch Underseat Carry-On is the compact choice for keeping essentials close. The main tradeoff is between a structured roller that is easy to move and a soft bag that can flex into tight spaces. Southwest’s size rules apply to the bag’s outside dimensions, including wheels and handles, so a bag labeled airline approved is not automatically a fit for every packing setup. I compare all 15 options by form, capacity, portability, and likely fit to help narrow the field. Read on for the full breakdown and a guide to choosing the right bag for your trip.

Key Takeaways
- The list spans three distinct formats: hard-sided spinner suitcases, soft duffels, and backpacks, each trading structure for flexibility in a different way.
- Several listings share near-identical names and dimensions: the Light Flight color options and Narwey duffels appear in multiple versions, so choose by the bag format and listed measurements rather than expecting a different travel design.
- Carry-on approval claims need a measurement check: the Flight Knight models are listed at 24 inches, so their stated dimensions deserve closer comparison with Southwest’s carry-on limit before purchase.
- Capacity numbers do not tell the whole packing story: the 40L duffels and 40L LOVEVOOK backpack offer generous stated volume, while a structured roller may be easier to pack consistently and roll through the airport.
- The TPRC underseat model fills a different role: it prioritizes compact access over the storage volume of the larger rollers and backpacks, making it a better match for essentials than a full wardrobe.

Carry On Luggage 22x14x9 Airline Approved, 40L Gym Duffle Bag for Travel
For Southwest trips where a change of clothes, workout kit, or damp swimwear needs its own space, this 40L duffle is more purpose-built than the Wrangler 22″ Hardside Spinner Carry-On. Its separate wet/dry pocket and shoe compartment help keep used gear away from clean clothes, while waterproof 900D nylon offers a softer, less fragile-feeling alternative to a hard shell. The listed dimensions—20.5 x 14 x 8.7 inches—fit within the stated 22 x 14 x 9-inch carry-on target, and a trolley sleeve makes it easier to pair with rolling luggage. The tradeoff is structure: it does not provide the protection or effortless rolling of the Wrangler, and 40 liters may feel tight for bulky packing or longer trips. I’d choose it for flexible weekend packing, not as a substitute for a laptop-focused bag.
Pros:- Listed dimensions fit within the stated 22 x 14 x 9-inch carry-on target.
- Separate wet/dry and shoe compartments isolate used or damp gear.
- Waterproof, tear-resistant 900D nylon suits trips where the bag may encounter spills or rough handling.
- Trolley sleeve and removable shoulder strap offer flexible carrying options.
Cons:- The soft-sided design offers less crush protection than the Wrangler hardside spinner.
- The 40-liter capacity may be restrictive for longer trips or bulky clothing.
- No padded laptop compartment is specified.
Best for: Southwest travelers taking weekend trips who pack shoes, gym clothes, or damp items and want a soft bag that fits over a suitcase handle.
Not ideal for: Travelers carrying a laptop that needs a dedicated padded compartment, packing bulky items, or preferring a wheeled bag with a rigid shell.
- Dimensions:20.5 x 14 x 8.7 inches
- Capacity:40 liters
- Material:900D waterproof nylon
- Weight:12.8 ounces
- Compartments:3
- Notable features:Wet/dry pocket, shoe compartment, trolley sleeve, multiple pockets, adjustable/removable shoulder strap
- Closure:Zipper
- Water resistance:Waterproof
Our verdict“Choose this duffle for short Southwest trips where separating shoes and damp gear matters more than wheels or rigid protection.”
Wrangler 22″ Hardside Spinner Carry-On Luggage, Charcoal
The Wrangler is the straightforward choice here for Southwest travelers who want a rigid-shell spinner without extras they may not need. At 6.4 pounds, it is lighter than the Flight Knight expandable case, and its four 360-degree wheels make airport walks easier than carrying the 40L gym duffle by hand. Compression straps and a lined interior help keep clothing in place, though its 38-liter capacity is slightly below that duffle’s 40 liters and well below the MATEIN HER backpack’s 45 liters. Pay attention to the listed dimensions: 14 x 9.5 x 22 inches, with a 9.5-inch width that exceeds the common 9-inch carry-on target in this roundup. Its ABS shell is not water resistant, and there is no built-in lock, so this is best for travelers who value simple rolling and a light case over extras and weather protection.
Pros:- At 6.4 pounds, it is lighter than the Flight Knight expandable hardside case.
- Four spinner wheels help reduce effort when moving through terminals.
- Compression straps and a fully lined interior help secure packed clothing.
- Rigid ABS shell provides more shape and crush protection than a soft duffle.
Cons:- Listed width is 9.5 inches, wider than the 9-inch target used by several bags in this roundup.
- The ABS case is not water resistant.
- No built-in lock or security features are specified.
Best for: Southwest travelers who prefer a lightweight, wheeled hard case for clothes and standard trip essentials, and are comfortable checking the airline’s current size rules.
Not ideal for: Travelers who need water resistance, an included security lock, expandable packing space, or strict adherence to a 9-inch listed width.
- Dimensions:14 x 9.5 x 22 inches
- Capacity:38 liters
- Weight:6.4 pounds
- Material:ABS
- Wheels:4 spinner wheels
- Handle:Telescopic extendable handle
- Interior:Fully lined with compression straps
- Water resistance:Not water resistant
Our verdict“Pick the Wrangler for uncomplicated rolling and a light hard shell, but check Southwest’s current carry-on dimensions against its listed 9.5-inch width.”
LOVEVOOK 40L Travel Backpack for Women Men with Garment Bag, Airline Approved Carry on Luggage Travel Essentials with 3 Packing Cubes, TSA Overnight Bags Weekender Essentials Backpacks fits 17″ Laptop
The LOVEVOOK stands apart from the MATEIN HER by prioritizing a built-in suit-roll system and a more compact listed footprint rather than maximum capacity. Its 18 x 12 x 7-inch dimensions leave room under the stated carry-on target, while the 180-degree opening and included three packing cubes make packing and security access less fiddly than with a basic duffle. A compartment for a laptop up to 17 inches, wet/dry storage, and a water-bottle pocket give it a useful mix for work trips and overnight travel. The garment system is the main reason to choose it: it aims to keep a packed outfit presentable without a separate garment bag. Still, the supplied data lists a weight of 1.57 kg, and the bag’s soft backpack format will not roll like the Wrangler or protect contents like a hard case. Its listed dimensions are unusually formatted, so confirm sizing before buying.
Pros:- Compact stated size of 18 x 12 x 7 inches fits within the roundup’s 22 x 14 x 9-inch target.
- Suit-roll system is designed to reduce wrinkles in a packed outfit.
- Includes three packing cubes and a 180-degree opening for organized packing and access.
- Laptop compartment fits devices up to 17 inches, with added wet/dry and water-bottle storage.
Cons:- At 1.57 kg, it is heavier than the listed 12.8-ounce gym duffle.
- Backpack carry requires wearing the load rather than rolling it through the airport.
- The provided product dimensions are unusually formatted in one section, so verify the size before purchase.
Best for: Southwest business and event travelers who want a compact carry-on backpack with a suit-roll feature, laptop storage, and included packing cubes.
Not ideal for: Travelers who want spinner wheels, rigid protection, a very light bag, or clear confidence in the listed dimension data before purchasing.
- Dimensions:18 x 12 x 7 inches
- Capacity:40 liters
- Weight:1.57 kg
- Material:Polyester
- Laptop compatibility:Up to 17 inches
- Compartments:4
- Pockets:4
- Notable features:Suit-roll system, three packing cubes, wet/dry compartment, 180-degree opening, luggage strap
Our verdict“Choose the LOVEVOOK when keeping a work outfit neat and carrying a large laptop matter more than wheels or the MATEIN HER’s larger stated capacity.”
Flight Knight 24x16x10 Expandable Carry-On Suitcase with TSA Lock, USB-C, Hardside, Silent Spinner Wheels, Yellow
Among the wheeled options here, the Flight Knight is the feature-heavy pick: it adds an expandable 49-liter interior, TSA-approved combination lock, USB-C port, and eight-wheel spinner setup. That is a clear step up in travel extras from the simpler Wrangler, which is lighter but has no listed lock, expansion, or water resistance. For Southwest carry-on use, though, its 24 x 16 x 10-inch listed size is the key tradeoff: it is larger than the 22 x 14 x 9-inch target used by several products in this roundup, and expanding it adds still more space beyond the stated dimensions. The hard shell offers impact protection and water resistance, but internal organization is limited compared with the LOVEVOOK backpack’s packing-focused layout. I’d pick it for travelers who value capacity and features and will confirm the airline’s current size allowance before flying.
Pros:- Expandable 49-liter capacity offers more packing room than the Wrangler’s 38 liters.
- TSA-approved combination lock adds a security feature absent from the Wrangler listing.
- USB-C port provides a convenient access point for device charging.
- Water-resistant shell and spinner wheels support practical airport travel.
Cons:- Listed 24 x 16 x 10-inch size exceeds the 22 x 14 x 9-inch target used by several roundup options.
- At 7.3 pounds, it is heavier than the Wrangler’s 6.4-pound listed weight.
- Limited internal organization may require separate packing cubes.
Best for: Travelers who want a feature-rich hardside case, need expandable packing space, and will verify that its listed dimensions are permitted for their Southwest itinerary.
Not ideal for: Travelers seeking a conservative 22 x 14 x 9-inch carry-on fit or those who prefer detailed internal organization and a lighter case.
- Dimensions:24 x 16 x 10 inches
- Capacity:49 liters
- Weight:7.3 pounds
- Material:ABS and polycarbonate
- Wheels:8 spinner wheels
- Lock:TSA-approved combination lock
- Notable features:Expandable design, USB-C port, water-resistant construction
- Pockets:4
Our verdict“Choose the Flight Knight for expansion, a lock, and a charging port only if its larger listed dimensions work for your Southwest travel plans.”
MATEIN HER Carry-On Backpack 22x14x9, 45L Large Travel Backpack for Women
For travelers who want to carry several days of clothing without switching to a wheeled case, the MATEIN HER offers the largest stated capacity in this batch at 45 liters. Its 20 x 14 x 9-inch dimensions stay within the 22 x 14 x 9-inch target cited in the product title, unlike the larger-listed Flight Knight. Ten pockets, a laptop compartment for devices up to 17 inches, packing accessories, and a rain cover make it more organized than the 40L gym duffle, which lacks a specified laptop sleeve. Anti-theft details and padded straps with a chest buckle also suit a bag that may spend long stretches on your back. The tradeoff is bulk: at 2.8 pounds before packing, it outweighs the LOVEVOOK’s compact-style option as listed, and 45 liters may be more bag than a minimalist weekend traveler needs.
Pros:- 45-liter capacity is larger than the 40-liter LOVEVOOK and gym duffle in this batch.
- Listed 20 x 14 x 9-inch dimensions fit within the 22 x 14 x 9-inch target.
- Laptop compartment accommodates devices up to 17 inches, with ten pockets for organization.
- Includes packing accessories, a rain cover, and padded straps with a chest buckle.
Cons:- At 2.8 pounds, it weighs more than the listed 12.8-ounce gym duffle.
- A full 45-liter backpack can feel bulky for short trips or under-seat use.
- It must be carried on the back rather than rolled through the terminal.
Best for: Travelers planning several days away who want a high-capacity backpack with laptop storage, packing aids, and hands-free airport movement.
Not ideal for: Minimal packers, travelers who prefer spinner wheels, or anyone who wants the lightest possible carry-on backpack.
- Dimensions:20 x 14 x 9 inches
- Capacity:45 liters
- Weight:2.8 pounds
- Material:Polyester
- Laptop compatibility:Up to 17 inches
- Pockets:10
- Compartments:4
- Water resistance:Waterproof; rain cover included
Our verdict“Pick the MATEIN HER for longer trips where a large, organized backpack matters more than low weight or wheels.”
Sweetcrispy 20 Inch Carry-On Luggage with Spinner Wheels
For Southwest travelers who prefer a wheeled case but want a compact footprint, the Sweetcrispy 20 Inch is a straightforward choice. Its listed dimensions are 22.44 x 14.96 x 9.45 inches, so check the airline’s current carry-on limits and allow for the shell, wheels, and handles when packed. At 6 pounds, it is lighter than the Light Flight case at 6.9 pounds, though the Light Flight expands from 33 to 41 liters while this one lists 35 liters. The Sweetcrispy adds an integrated TSA lock and expandable storage, useful for keeping a short-trip load contained. The ABS shell and four spinner wheels suit travelers who value structure and easy rolling, but it lacks a listed water-resistance rating beyond the product description’s claim and offers less capacity than a 40L backpack or duffle.
Pros:- Six-pound weight is lower than the listed Light Flight suitcase
- Four spinner wheels and a telescopic handle support rolling through terminals
- Expandable design and two interior sections help organize short-trip packing
- Built-in TSA lock adds a security feature not listed for the duffle options
Cons:- Listed dimensions exceed the common 22 x 14 x 9-inch reference, so packed fit should be checked
- At 35 liters, it holds less than the 40L LOVEVOOK backpack and Narwey duffles
- ABS hard shell is less flexible for squeezing into a tight overhead space
Best for: Southwest passengers who want a compact, structured hard-shell case for short trips and prefer spinner wheels over carrying a backpack.
Not ideal for: Travelers who need a soft-sided bag that can compress into tight storage, or those prioritizing a verified Southwest size fit, maximum capacity, or a sub-six-pound case.
- Dimensions:14.96 x 9.45 x 22.44 inches
- Weight:6 pounds
- Capacity:35 liters
- Material:ABS hard shell
- Wheels:4 spinner wheels
- Lock:TSA lock and key lock
- Expandable:Yes
- Organization:2 sections and 3 pockets
Our verdict“Choose the Sweetcrispy for a lighter, lock-equipped hard-shell case for short trips, but check its listed dimensions before flying Southwest.”
Narwey Carry-On Duffle Bag 22x14x9 Airline Approved, Packable, 40L, Navy Blue
The Narwey 40L Duffle in Navy Blue suits travelers who want a soft bag that stores flat between trips and can carry more than the Sweetcrispy’s listed 35-liter capacity. Its actual listed dimensions are 20.5 x 13.8 x 8.7 inches, smaller than the 22 x 14 x 9-inch label in the title; that may help with fit, but the bag’s loaded shape can still change how it sits in an overhead bin. The adjustable padded shoulder strap gives it a carrying option the LOVEVOOK backpack handles differently, while the duffle’s single compartment makes access simple but packing less segmented. Polyester construction and a waterproof claim suit varied travel, yet there is little listed protection for small essentials: the data names one compartment and an exterior pocket, not a fuller organizer system. I’d pick it for flexible packing, not for hands-free comfort over long walks.
Pros:- 40-liter capacity exceeds the Sweetcrispy suitcase’s listed 35 liters
- Lightweight at 0.4 kg and designed to fold for storage
- Adjustable padded shoulder strap offers a carry option beyond the web handles
- Waterproof polyester claim is useful for trips where a soft bag may encounter wet conditions
Cons:- One main compartment offers less organization than the LOVEVOOK backpack’s eight pockets
- The title’s 22 x 14 x 9-inch wording differs from the smaller listed dimensions
- A shoulder-carried duffle can become uncomfortable when packed heavily
Best for: Southwest travelers who want a lightweight, foldable weekend bag with a shoulder strap and room for bulky, less structured items.
Not ideal for: Commuters carrying a laptop and many small items, or travelers who need backpack-style weight distribution and defined compartments.
- Dimensions:20.5 x 13.8 x 8.7 inches
- Capacity:40 liters
- Weight:0.4 kg
- Material:Polyester
- Water resistance:Waterproof (as listed)
- Compartments:1
- Closure:Zipper
- Strap:Adjustable
Our verdict“Choose this Narwey when packability and a roomy soft-sided shape matter more than compartment organization or hands-free carrying.”
LOVEVOOK 40L Travel Backpack for Women and Men, Carry-On Approved
Among these five options, the LOVEVOOK 40L Travel Backpack is the clearest choice for travelers who want organization rather than a single open packing space. It lists eight pockets, a laptop sleeve for devices up to 17 inches, wet pockets, and packing cubes—more built-in sorting than either Narwey duffle, each of which lists one compartment. At 18 x 14 x 8 inches, its stated dimensions are within the common 22 x 14 x 9-inch reference, though travelers should check Southwest’s current rules and account for how a full bag bulges. The backpack’s format also keeps hands free, unlike the shoulder-carried Narwey bags, but the product data does not specify back padding for long airport walks. Water-resistant polyester helps with light exposure, while hand-wash-only care is less convenient than a wipe-clean surface. Its 40-liter capacity and laptop fit make it better suited to a few days away than a minimal personal-item setup.
Pros:- Eight pockets provide more organization than either Narwey duffle
- Padded laptop sleeve is listed for devices up to 17 inches
- Packing cubes and wet pockets support separated packing
- 18 x 14 x 8-inch listed dimensions fit within the common carry-on reference
Cons:- Hand-wash-only care takes more effort than cleaning a hard shell
- Back padding for extended carrying is not specified
- A full 40-liter backpack may feel bulky even if its listed dimensions fit
Best for: Southwest travelers taking a three-to-five-day trip who carry a laptop and want separate spaces for clothes, wet items, and accessories.
Not ideal for: Travelers who prefer wheels, need a specified comfortable back-support system for extended walks, or want a bag that can go in a washing machine.
- Dimensions:18 x 14 x 8 inches
- Capacity:40 liters
- Laptop compatibility:Up to 17 inches
- Pockets:8
- Material:Polyester
- Water resistance:Water resistant
- Included organization:Packing cubes and wet pockets
- Care:Hand wash only
Our verdict“Pick the LOVEVOOK backpack if laptop protection and organized, hands-free packing matter more than wheels or easy cleaning.”
Light Flight Carry On Luggage 22x14x9 Airline Approved Suitcase, Black/Brown
The Light Flight Carry-On earns its place for travelers who want spinner convenience with room to bring back extra items. Its capacity expands from 33 to 41 liters, giving it more flexibility than the Sweetcrispy’s 35-liter listing and bringing it closer to the 40-liter soft bags when expanded. That extra space has a fit tradeoff: the listed dimensions are 21.65 x 9.57 x 14.96 inches, and expansion can make an overhead fit less predictable. The 6.9-pound ABS case is heavier than the Sweetcrispy, while its four 360-degree spinner wheels make it easier to roll than either Narwey duffle. A combination lock and organized two-section interior add structure, but this model is explicitly not water resistant. I’d favor it for trips where flexible packing volume matters more than weather protection or the simplest carry-on sizing.
Pros:- Capacity expands from 33 to 41 liters for extra packing flexibility
- Four spinner wheels reduce the effort of moving through terminals
- Two interior sections provide more structure than the Narwey duffles
- Combination lock is listed for securing the case
Cons:- At 6.9 pounds, it is heavier than the Sweetcrispy 20-inch case
- Not water resistant, unlike the water-resistant LOVEVOOK backpack and waterproof Narwey duffles
- Listed width is 9.57 inches before any expansion, so overhead fit merits checking
Best for: Southwest travelers who prefer a rolling hard-shell suitcase and want expandable room for return-trip packing.
Not ideal for: Travelers who need water resistance, a very lightweight case, or predictable overhead fit after expanding the bag.
- Dimensions:21.65 x 9.57 x 14.96 inches
- Weight:6.9 pounds
- Capacity:33 liters, expandable to 41 liters
- Material:ABS hard shell
- Wheels:4 spinner wheels
- Lock:Combination lock
- Water resistance:Not water resistant
- Interior:2 sections
Our verdict“Choose the Light Flight if you want a spinner that can expand for extra packing, and skip it if water protection or the smallest footprint comes first.”
Narwey Carry-On Luggage 22x14x9 Airline Approved Foldable Duffle Bag for Travel, 40L, Black
This black Narwey foldable duffle is the lightest listed option in this group at 14.08 ounces, making it appealing to travelers who want to save carry weight and pack the bag away after a trip. Its 40-liter capacity is larger than the Sweetcrispy’s 35-liter listing, but the open, single-compartment layout is far less orderly than the LOVEVOOK backpack’s eight-pocket setup. The listed dimensions are 20.5 x 13.8 x 8.7 inches, smaller than the 22 x 14 x 9-inch wording in its title; confirm fit using the packed bag’s actual shape rather than relying on the title alone. A padded adjustable shoulder strap adds carrying comfort, though a loaded duffle still puts its weight on one shoulder. Polyester is described as waterproof, but there is no listed laptop sleeve or internal organizer for valuables and small items.
Pros:- Listed weight of 14.08 ounces is far below the hard-shell suitcase options
- 40-liter capacity provides more listed volume than the Sweetcrispy case
- Foldable polyester construction stores compactly between trips
- Adjustable padded shoulder strap supports carrying comfort
Cons:- One compartment offers much less organization than the LOVEVOOK backpack
- Listed dimensions are smaller than the 22 x 14 x 9-inch title wording
- Shoulder carrying can be tiring with a full 40-liter load
Best for: Travelers who want a very light, foldable carry-on for gym gear, weekend clothes, or flexible packing without a rigid case.
Not ideal for: Laptop commuters, travelers who need divided storage, or anyone who finds shoulder-carried bags uncomfortable when fully loaded.
- Dimensions:20.5 x 13.8 x 8.7 inches
- Capacity:40 liters
- Weight:14.08 ounces
- Material:Polyester
- Water resistance:Waterproof (as listed)
- Compartments:1
- Closure:Zipper
- Strap:Adjustable padded shoulder strap
Our verdict“Choose this Narwey for a very light, stowable duffle, but choose the LOVEVOOK backpack if organized laptop storage is a priority.”
Light Flight Carry On Luggage 22x14x9 Airline Approved Suitcase, Teal Blue
For Southwest travelers who want a conventional overhead-bin roller without adding much weight, this 6.9-pound ABS suitcase is a practical fit. Its listed 21.65 x 9.57 x 14.96-inch dimensions are close to the stated 22 x 14 x 9-inch carry-on format, though the width and depth are presented in a different order, so I’d verify the packed bag against current airline limits. The 33L interior expands to 41L, giving light packers room for a few extra items on the return trip. Compared with the underseat TPRC, it holds more but needs overhead-bin space; against the Samsonite Omni 2, it weighs less but has an ABS shell rather than polycarbonate and a much shorter stated feature list. Its limits are the modest unexpanded capacity and lack of water resistance.
Pros:- Light 6.9-pound listed weight helps keep the suitcase itself from taking up much of a carry-on load.
- Expansion adds capacity from 33L to 41L for return-trip purchases or extra clothing.
- Four 360-degree spinner wheels support maneuvering through terminals.
- Multiple interior compartments help separate packed items.
Cons:- The 33L unexpanded capacity may feel tight for longer trips or bulky clothing.
- The shell is not water resistant.
- Listed item dimensions differ in order and measurement from the 22 x 14 x 9-inch title, so size fit should be checked.
Best for: Travelers who want a lightweight overhead roller for short trips and occasional extra packing space.
Not ideal for: People carrying bulky gear, traveling in wet conditions, or unwilling to check the bag’s exact dimensions against airline limits.
- Size:20 inches
- Item dimensions:21.65 x 9.57 x 14.96 inches
- Weight:6.9 lbs
- Capacity:33L; expandable to 41L
- Material:ABS hard shell
- Wheels:4 spinner wheels
- Handle:Telescopic extendable handle
- Water resistance:Not water resistant
Our verdict“Choose this for a light, expandable roller on shorter trips, but verify its dimensions and skip it if you need weather protection or substantial packing capacity.”
Flight Knight 24″ Expandable Hardside Carry-On Suitcase with TSA Lock and USB-C Port
This Flight Knight offers the most add-ons in this group: a TSA-approved combination lock, USB-C port, water-resistant PC+ABS shell, and expandable storage. Those features suit travelers who want device access and added packing flexibility in one roller, but its 24 x 16 x 10-inch listed dimensions expand to 24 x 16 x 12 inches. That is larger than the 22 x 14 x 9-inch format associated with the Light Flight and Samsonite Omni 2, so I would not treat the airline-fit claim as a guarantee for Southwest’s carry-on limits. Its stated 49L to 58L capacity is generous, yet that size brings a real fit tradeoff. Choose the more compact Omni 2 if matching a standard carry-on footprint matters more than capacity and extras.
Pros:- Expands from 49L to 58L for travelers who need more room.
- TSA-approved combination lock is included.
- Water-resistant, anti-scratch PC+ABS shell offers more stated protection than the ABS Light Flight models.
- USB-C port and eight double spinner wheels add convenience and maneuverability.
Cons:- Listed dimensions exceed the 22 x 14 x 9-inch format of the Light Flight and Samsonite options.
- Expansion increases depth to 12 inches, adding further uncertainty about overhead-bin fit.
- A power bank is not specified as included, so the USB-C port may require a separate power source.
Best for: Travelers prioritizing a built-in lock, USB-C access, and high expandable capacity who will confirm permitted dimensions before flying.
Not ideal for: Southwest passengers seeking a reliably standard-size overhead carry-on, especially if they plan to use the expansion zipper.
- Dimensions:24 x 16 x 10 inches; expands to 24 x 16 x 12 inches
- Weight:5.95 lbs
- Capacity:49L; expandable to 58L
- Material:PC+ABS hard shell
- Wheels:8 double spinner wheels
- Lock:TSA-approved combination lock
- Port:USB-C charging port
- Warranty:3 years
Our verdict“Pick this for its lock, USB-C port, and large capacity only if you verify its oversized listed dimensions against your Southwest flight’s carry-on rules.”
Samsonite Omni 2 Airline Approved Carry-On Luggage
The Samsonite Omni 2 is the most established-feeling choice on this list based on its stated polycarbonate shell and 10-year limited warranty. Its 22 x 14 x 9-inch exterior aligns with the carry-on dimensions targeted by this roundup, making it a more straightforward overhead-bin candidate than the larger Flight Knight. A scratch-resistant shell and 1.5-inch expansion help balance durability and packing flexibility, while the USB power hub offers a way to connect a device when paired with a power source. Compared with the lighter 6.9-pound Light Flight, the Omni 2 weighs 7.5 pounds and carries less appeal for strict weight savers; compared with the Flight Knight, it lacks an included TSA lock. Its capacity is listed in cubic inches rather than liters, so direct capacity comparison is less convenient.
Pros:- Exterior dimensions are listed as 22 x 14 x 9 inches, matching the format this roundup targets.
- Polycarbonate shell is described as scratch-resistant.
- 10-year limited warranty offers longer stated coverage than the Flight Knight’s three years.
- Expandable design and USB power hub add packing flexibility and device connectivity.
Cons:- At 7.5 pounds, it is heavier than both Light Flight carry-ons and the Flight Knight.
- A TSA lock is not included.
- Capacity is listed as 2,772 cubic inches, which is less intuitive to compare with liter-rated alternatives.
Best for: Frequent flyers who want a standard-format hard-shell carry-on backed by a long limited warranty.
Not ideal for: Travelers who need the lightest option, an included TSA lock, or a capacity figure that is easy to compare in liters.
- Exterior dimensions:22 x 14 x 9 inches

- Weight:7.5 lbs
- Capacity:2,772 cubic inches
- Material:Polycarbonate

Light Flight Carry On Luggage 22x14x9 Airline Approved Suitcase, Royal Blue
The Royal Blue Light Flight takes a straightforward approach: 22 x 14 x 9-inch listed dimensions, an ABS shell, spinner wheels, and an organized interior with dual compartments and pockets. For Southwest travelers seeking a familiar overhead roller, its stated size is easier to compare with the airline-oriented format than the Flight Knight’s 24 x 16 x 10-inch body. Its expansion from 33L to 41L is useful for a return journey, but I’d treat expanded capacity as a tradeoff rather than a free upgrade because more packed depth can make overhead fit less predictable. Compared with the teal Light Flight, this version has nearly the same core proposition and capacity; the supplied data mainly distinguishes it by its explicit dimensions and three-stage handle. It lacks water resistance and is not the best choice for bulky loads.
Pros:- Listed 22 x 14 x 9-inch dimensions make its intended carry-on footprint clear.
- Expandable capacity rises from 33L to 41L.
- 360-degree spinner wheels help with terminal maneuvering.
- Dual compartments and storage pockets provide useful packing separation.
Cons:- Expansion may make overhead fit less predictable when packed out.
- ABS shell is not stated to be water resistant.
- The 33L base capacity may be limiting for longer trips or bulky gear.
Best for: Travelers who want a simple, organized hard-shell roller with stated 22 x 14 x 9-inch dimensions for short trips.
Not ideal for: People packing bulky items, needing a water-resistant bag, or relying on the expanded size to fit overhead without checking measurements.
- Dimensions:22 x 14 x 9 inches
- Weight:6.94 lbs
- Capacity:33L; expandable to 41L
- Material:ABS hardshell
- Wheels:360-degree spinner wheels
- Handle:3-stage telescopic handle
- Interior:Dual compartments and storage pockets
Our verdict“Pick the Royal Blue Light Flight for organized short-trip packing in a clearly listed carry-on format, but avoid relying on expansion when overhead space is tight.”
TPRC 15” Underseat Carry-On Luggage Airline Approved Personal Item with USB Charging Port, Black
The TPRC serves a different Southwest packing strategy: rather than competing with the Samsonite Omni 2 for overhead-bin space, this 23.85L underseat roller is designed to keep essentials close by as a personal item. Its 14 x 15 x 8-inch exterior is compact, and the nylon construction with two wheels suits quick access to documents, a change of clothes, or a laptop-sized load. The USB port is convenient when paired with a power bank, which is not included. Compared with the hard-shell Light Flight models, it is softer and smaller, so it offers less protection and substantially less room; in return, it can complement a larger carry-on rather than replace one. It is not water resistant, and its capacity is better suited to short trips than a full vacation wardrobe.
Pros:- Compact 14 x 15 x 8-inch listed dimensions are designed for underseat use.
- 23.85L capacity works well for essentials and short-trip packing.
- USB charging port provides a convenient connection point when paired with a power bank.
- Two wheels and a telescopic handle make it a rolling alternative to a shoulder bag.
Cons:- The power bank needed to use the USB port is not included.
- Not water resistant, so contents may need separate protection in wet conditions.
- Limited capacity makes it a poor substitute for a full-size carry-on on longer trips.
Best for: Southwest travelers who want a compact underseat bag for essentials, short trips, or use alongside an overhead carry-on.
Not ideal for: Travelers looking for a single bag for longer trips, hard-shell protection, or dependable coverage in wet weather.
- Exterior dimensions:14 x 15 x 8 inches
- Weight:5.2 lbs
- Capacity:23.85L
- Material:Nylon shell, 1680 denier
- Wheels:2
- Handle:Telescopic extendable handle
- Pockets:2
- Water resistance:Not water resistant
Our verdict“Choose the TPRC to keep a compact set of essentials under the seat, not as your only suitcase for an extended trip.”
How We Picked
I compared the 15 listed options against the needs of Southwest travelers: checking the stated dimensions against the airline’s published carry-on and personal-item limits, distinguishing overhead-bin bags from underseat designs, and weighing how each format handles packing, carrying, and rolling. A label such as “airline approved” is a useful starting point, not a guarantee; external measurements, including wheels, handles, and bulging pockets, matter more.
The ranking favors options with a clear use case and a plausible fit for Southwest’s carry-on allowance, then accounts for organization, portability, versatility, and the tradeoffs implied by each design. I treated duplicate color listings as variations of the same suitcase rather than separate innovations, and gave extra scrutiny to products whose stated dimensions appear larger than the airline’s standard carry-on limit. Since the supplied product details do not establish measured packed dimensions or durability testing, I avoid claiming verified fit or long-term performance.

Factors to Consider When Choosing Carry On For Southwest Airlines
Southwest bag shopping is less about finding a label that says “airline approved” and more about matching the bag’s real packed shape to your trip. These checks can help you avoid paying for capacity you cannot use or choosing a format that is awkward for your airport routine.
Measure the Outside, Not Just the Main Compartment
Airline limits apply to the bag’s exterior, so measure from the floor to the top of the handle and include wheels, fixed pockets, and anything that sticks out. A listed size can refer to the shell alone or may round measurements, which makes the product page worth checking closely. Soft bags can compress when lightly packed, but an overstuffed front pocket can still push them beyond the limit. Do not assume that a bag marketed for airlines will fit every carrier’s sizer. Leave a little room below the maximum if your packing style tends to make a bag bulge.
Match the Bag Format to How You Move
Spinner suitcases are convenient across long terminal walks and keep packed items in a defined shape, but they need a clear path to roll and can be cumbersome on stairs. Backpacks make hands-free movement easier, though a heavily loaded 40L pack can feel tiring on your shoulders. Duffels can flex into tight storage spaces, yet their weight often rests on one shoulder unless they have backpack straps. Think through your route from curb to gate, not just the time spent in the cabin. Travelers changing trains or carrying a child may value hands-free carry more than a rigid shell.
Choose Capacity for the Trip, Not the Biggest Number
Liters are useful for comparing broad capacity, but they do not show whether a bag’s compartments suit your clothes, shoes, or electronics. A garment section may reduce the room available for other items while helping keep formal clothing flatter. Packing cubes can make a soft backpack easier to organize, but they do not increase the airline’s size allowance. For a short trip, extra capacity can tempt you to overpack and make the bag harder to lift. Start with the items you actually need, then select a layout that keeps them accessible.
Decide Whether You Need an Underseat Bag or an Overhead Carry-On
A compact underseat bag is useful for a change of clothes, medication, electronics, and other items you want within reach. It should not be treated as a full-size carry-on substitute if you need space for several days of clothing. A larger overhead bag gives you more packing room but may be less convenient to carry through a crowded cabin. Southwest’s personal-item and carry-on rules are separate, so check the current dimensions for each allowance before choosing. If you plan to bring both, make sure the smaller bag can fit beneath the seat without obstructing your essentials.
Treat Expandability as Extra Capacity, Not Guaranteed Fit
An expansion zipper can help on the return trip, but expanding a bag may make it exceed the permitted exterior dimensions. The same concern applies to stuffed pockets on backpacks and duffels, even when the empty bag appears compliant. Compare the unexpanded and expanded measurements, then decide whether the extra room is worth the possible fit tradeoff. If you expect to use the added space, pack with the expanded shape in mind from the start. A bag that fits only when half-empty may not suit a traveler who brings souvenirs or bulky layers home.
Pay for Features You Will Use
Charging ports, TSA locks, packing cubes, and garment compartments can make travel more convenient, but each adds little if it does not match your routine. A built-in USB port typically still requires you to supply a compatible power bank, so check the product details before treating it as a charger. Locks can help secure zippers but do not replace keeping valuables with you. Spinner wheels matter most if you roll a bag often; a backpack’s straps matter more if you walk long distances. Put fit and comfortable handling ahead of a long feature list.
Frequently Asked Questions
Can I rely on a carry-on bag labeled “airline approved” for a Southwest flight?
Not by that label alone. Airlines may have different size limits, and product listings do not always make clear whether measurements include wheels, handles, and exterior pockets. Compare the full outside dimensions with Southwest’s current carry-on limit before packing. Also account for how much the bag bulges once filled. If the fit is close, a less rigid or smaller option can offer more margin.
Are the Flight Knight 24-inch suitcases safe choices for Southwest’s carry-on allowance?
The listed 24-inch dimensions warrant caution because that figure may exceed Southwest’s standard carry-on height limit, depending on how the manufacturer measures the case. Check the complete height, width, and depth, including wheels and handle, rather than relying on the model name or approval claim. Expansion can make the packed case larger still. If you need a bag with less sizing uncertainty, compare a model explicitly listed near the airline’s maximum dimensions. Confirm the current airline rules before your trip.
Should I choose a 40L backpack or a spinner suitcase for a weeklong trip?
Choose based on how you will carry the packed weight and what you need to organize. A 40L backpack can keep your hands free and may offer useful compartments, but a full load can strain your shoulders and its packed shape can bulge. A spinner suitcase carries weight on wheels and gives clothing a more structured space, though stairs and uneven pavement can be less convenient. Either format can be a poor fit if its packed exterior exceeds the airline’s limit. Test your planned packing list against both the dimensions and the carrying method.
Does a compact underseat bag count as my Southwest carry-on?
A compact bag may serve as a personal item when it fits the airline’s current personal-item requirements and can be stowed under the seat. That allowance is distinct from the larger carry-on allowance, so check the current rules if you plan to bring another bag. The TPRC 15-inch model is described as an underseat option, which points to a different role than a full-size overhead suitcase. Measure it while packed, since a rigid side pocket or overfilled compartment can affect fit. Keep essentials accessible without making the bag too large to stow.
Is a soft duffel a safer choice than a hard-sided suitcase for fitting a sizer?
A soft duffel can compress more readily than a hard shell, which may help when the bag is not packed to its limit. That flexibility does not make oversized dimensions acceptable, and an overfilled duffel can be difficult to squeeze into a sizer. A hard-sided case holds its shape and protects packed items, but offers less give around tight spaces. Choose the format that fits your usual load rather than relying on last-minute compression. Measure the bag packed as you expect to travel.
Conclusion
For a balanced overhead option, my best overall is the Wrangler 22-inch Hardside Spinner; it offers the familiar rolling format without the 24-inch sizing question attached to the Flight Knight listings. For best value in flexibility, I would look at the Narwey 40L Carry-On Duffle if a soft, packable bag suits your packing habits, while recognizing that its packed shape still needs a dimension check. The best premium-style pick is the Samsonite Omni 2 for shoppers who prefer an established suitcase line, though verify its exact dimensions and included features before deciding. For beginners, the Wrangler is the straightforward starting point; travelers who prefer hands-free organization should compare the LOVEVOOK backpack. For specific needs, choose the TPRC underseat model for a compact essentials bag, or the LOVEVOOK garment-bag version when keeping clothing organized matters more than a simple open packing space. Whichever format you choose, confirm current Southwest limits against the bag’s full outside measurements before flying.
