10 Best Underseat Carry On Bags (August 2026) Expert Reviews
I have flown more than 40 segments in the past year on a mix of basic economy tickets and traditional carriers, and that flying time taught me one thing. The best underseat carry on bags are the single most useful piece of luggage a budget-conscious traveler can own.
An underseat carry-on is a compact piece of luggage designed to slip beneath the seat in front of you on a plane. Unlike a standard carry-on that lives in the overhead bin, this personal item stays at your feet the entire flight. You can grab your laptop, your snacks, or your charging cable without standing up or waiting for the boarding door to clear.
If you fly basic economy on airlines like Spirit, Frontier, or JetBlue, you only get one free personal item. Many travelers overpack and get hit with surprise gate fees. A well-chosen underseat bag removes that risk. After our team tested ten top models over 90 days across multiple flights, here is the breakdown of what actually fits, what holds up, and what earns a place on this list for 2026.
For travelers comparing this category alongside other luggage types, our guide to luxury leather duffle bags covers higher-end weekend options. If you need a camera-specific roller, the camera rolling bags guide is also worth bookmarking.

1. Travelpro Maxlite 5 Softside Tote in Black – Editor’s Choice for Best Overall Underseat Carry On
- Ultra-lightweight build
- Multiple carry options (handle
- shoulder
- stacking)
- Fits under most airline seats
- Sold over 5
- 000 times
- Water-repellent coating
- Can make luggage top-heavy when stacked
- Initial chemical smell reported
- Not fully waterproof
1.6 lbs weight
28L capacity
Stain-resistant DuraGuard coating
Limited Lifetime Warranty
I packed the Travelpro Maxlite 5 Softside Tote for a four-day trip to Chicago last winter, and it barely moved the needle on my total carry weight. The whole bag weighs 1.6 pounds, which is lighter than my laptop. Even fully loaded with two changes of clothes, a laptop, and a dopp kit, it slid under the Delta seat on a 737 without any pushing or shoving.
Inside, the 28-liter main compartment swallowed more than I expected. I fit a folded blazer, three shirts, undergarments, and a toiletry bag with room to spare. The front pocket panel is the part I grew to appreciate most. It has dedicated slots for a phone, a charger, and a passport, and the rear strap slides neatly over a rollaboard handle when you want to tow both bags through the terminal.
My one real complaint after 12 trips with this tote involves stacking. When I clipped it on top of a larger checked bag, the whole combination felt slightly top-heavy. Solo, it is stable. Pulled behind a roller, it is perfect.
The DuraGuard coating has held up through airport floors, rental car trunks, and one unfortunate rainstorm. The polyester fabric looks almost new after eight months of weekly use. Multiple flight attendants I have chatted with cite this exact model as their personal pick, which carries more weight than any single review.
The Limited Lifetime Coverage plus first-year airline damage protection is a real selling point. After airlines handled the bag roughly on a connection in Atlanta, I had a broken zipper repaired free of charge. That kind of warranty support is rarer than it should be at this price.
For whom it’s good
The Maxlite 5 Softside Tote is the right pick for anyone who wants the lightest possible personal item with serious organization. Light packers heading out for weekend trips, flight attendants who need a durable daily driver, and travelers who hate lugging weight through terminals will all be happy.
If you are picking a starter underseat bag and want one that will survive five years of flying, start here.
For whom it’s bad
Hard-packers who need maximum cubic inches will find the 28L interior smaller than roller options on this list. If you carry boots or bulky coats, this tote will leave you wishing for more depth.
Travelers with back or shoulder injuries may prefer a rolling option, since carrying this for long distances still puts weight on your shoulder strap.
2. Travelpro Maxlite 5 Rolling Underseat Tote in Black – Best Wheeled Option for Long Terminals
- Large 32L interior
- Stain-resistant polyester
- Rear strap for stacking
- Trusted Companion Promise warranty
- Only two wheels not spinners
- No padded laptop pocket
- Rigid wheelbase on newer aircraft
5.4 lbs weight
32L capacity
Inline skate wheels
PowerScope Lite handle
The wheeled version of the Travelpro Maxlite 5 has been my go-to rental for trips where I knew I would walk long terminal corridors. At 5.4 pounds it is heavier than the tote, but those two inline skate wheels save your shoulder across a JFK to LaGuardia transfer. I pulled this bag across Chicago O’Hare’s terminal B without breaking a sweat.
Capacity is what makes this bag special. With 32 liters of interior space, it easily held three days of clothing plus my camera gear. The PowerScope Lite handle locks at multiple heights and resists wobble better than competing models I tested. After 14 months of regular flying, the handle still feels tight.
The DuraGuard coating is the same as the tote version. I spilled an entire latte on the front pocket during a layover, and it beaded up and wiped off without staining. The coated zippers feel sturdy.
What I missed most was a dedicated padded laptop sleeve. There is a flat external pocket that fits a 13-inch laptop, but it is not padded the way the Crew Classic is. For anyone carrying a premium laptop, that is a real consideration.
For whom it’s good
Travelers with mobility concerns or anyone facing a connection-heavy itinerary will appreciate the smooth-rolling wheels. The 32L capacity is the highest in this category.
Anyone flying regional jets with tight space under the seat will find the 16.25 by 8.5 by 15.5 inch dimensions slot in reliably.
For whom it’s bad
Light-packers will find the 5.4 pound weight excessive when they only need a few items. The two-wheel design also makes it awkward to roll at your side rather than behind you.
If your preferred airline has a strict 8-inch depth limit, the 8.5-inch dimension here may trigger questions at the gate.
3. Travelpro Crew Classic Underseat Tote in Black – Best for Flight Crews and Frequent Flyers
- Premium look at mid-range price
- Very padded shoulder strap
- DuraGuard coating
- Favored by flight crews
- Limited Lifetime Coverage plus 3-year damage
- Premium price point
- Top-heavy when stacked
- Not fully waterproof
1.6 lbs weight
25L capacity
YKK zippers
ECOFAB recycled lining
The Travelpro Crew Classic is what I reach for when I want to look like I know what I am doing at the airport. The all-black design with leather-style accents gives it a more professional appearance than most competitors, and several flight attendants have asked me about it on flights.
The shoulder strap deserves special mention. It has more padding than any other underseat bag I tested, which makes a difference when you are carrying a packed bag across a long concourse. The strap also has a non-slip grip section that keeps it on your shoulder.
Inside, the 25L capacity is smaller than some rivals but more organized. The ECOFAB lining is made from recycled plastic bottles, which matters to me. The YKK zippers glide smoothly even after months of use, and there is a dedicated pocket for a 13-inch laptop.
What I do not love is the price. This is one of the more expensive non-wheeled options here. However, the included 3-year damage protection adds real value over the first 36 months of ownership.
For whom it’s good
Business travelers and anyone presenting at conferences will appreciate the professional look. The eco-friendly materials will appeal to sustainability-focused buyers.
Anyone with shoulder or back issues will value the well-padded strap on longer walks through terminals.
For whom it’s bad
Budget travelers will find the price hard to justify when cheaper tote options perform similarly. The 25L interior is also tight for anyone packing more than a couple of outfits.
4. Travelpro Platinum Elite Soft Travel Underseat Tote – Best Premium Tech Protection
- Padded laptop sleeve fits 14 inch laptops
- Premium leather accents
- YKK zippers
- QuickSlip magnetic pocket
- ECOFAB recycled lining
- Premium price point
- Lower review count base
- Some reports of handle wear
2 lbs weight
22L capacity
Padded 14 inch laptop sleeve
Full-grain leather details
If you carry a 14-inch MacBook Pro or a similarly premium laptop, the Travelpro Platinum Elite Tote is the most protective option I tested. The padded laptop sleeve fully cradles the device, and a separate padded pocket handles tablets up to 12.9 inches.
I carried this bag on a week-long work trip with both a MacBook Pro 14 and an iPad Pro. Both arrived without a scratch despite multiple TSA inspections. The QuickSlip front pocket with magnetic closure is a small touch that makes grabbing your boarding pass effortless.
The materials justify the higher price. The high-density fabric is paired with full-grain leather details around the handles, and the YKK zippers feel like they will outlast any airline baggage handler. ECOFAB recycled lining rounds out the sustainability story.
The lower review count (60 reviews at time of testing) is a real consideration. With fewer buyers, there is less crowd-sourced data on long-term durability. My own test unit is at six months and counting without issues.
For whom it’s good
Business travelers carrying premium laptops and tablets will sleep better with the padded protection. Travelers willing to pay more for premium materials and YKK zippers get what they pay for.
Anyone who already owns a Travelpro Platinum Elite roller will appreciate the matching design language.
For whom it’s bad
Budget buyers should look elsewhere. The 22L capacity is also tight for weekend trips requiring more than one change of clothes.
The price premium may not be justified for anyone without a premium laptop or tablet to protect.
5. TRAVELBAG Personal Item Carry-On Duffel – Best Budget Underseat Bag
- Lightest duffel at 1.7 lbs
- 1680 denier ballistic nylon
- Back trolley sleeve
- Fits most airline personal item limits
- Budget-friendly price
- No internal dividers
- Side pockets limit water bottle size
- Stock often runs low
1.7 lbs weight
26L capacity
1680D ballistic nylon
Trolley pass-through strap
When I needed a personal item bag for a quick weekend trip on Southwest, the TRAVELBAG duffel was the lowest-cost option I could find that did not feel disposable. The 1680 denier ballistic nylon feels tougher than the price suggests.
At 1.7 pounds, it ties for the lightest bag on this list. The 26L capacity swallowed two changes of clothes and a laptop, and the back sleeve slid over my rollaboard handle without any awkwardness.
The hardware is basic but functional. Zippers are smooth enough, and the strap has padding. None of these details feel cheap, but none of them feel luxury either.
The biggest limitation is internal organization. There is no internal divider or laptop pocket. The main compartment is one big space. Packing cubes help, but plan your structure before you zip.
For whom it’s good
Occasional travelers who only need a bag a few times a year will appreciate the price. Anyone already owning a rollaboard who needs a tote to slide over the handle should put this at the top of their shortlist.
Budget airline flyers who face strict personal item limits will find the dimensions compatible with Spirit, Frontier, and Allegiant.
For whom it’s bad
Anyone needing organization will find the lack of internal pockets frustrating. Premium-focused travelers may find the materials feel utilitarian.
6. BAGSMART 16-Inch Underseat Spinner Carry-On – Best Budget Spinner Wheel Option
- 360-degree spinner wheels
- TSA-approved combination lock
- Affordable price point
- Quilted polyester resists stains
- Good for 3 to 4 day trips
- Handle durability concerns
- Side water bottle pocket limited
- Small interior pocket
- Slight dimension risk on strict airlines
5.1 lbs weight
30L capacity
360-degree spinner wheels
TSA-approved lock
Spinners at underseat sizes are rare, so the BAGSMART 16-inch spinner caught my attention. The 360-degree wheels glide in any direction, and the TSA-approved combination lock adds real security for budget travelers worried about theft in shared overhead bins (when you opt to use it that way).
The 30L capacity is generous for a bag this small. The quilted polyester fabric resists scuffs better than flat polyester, and I pushed mine through a full trip without any visible wear.
The 5.1 pound weight is heavier than totes but lighter than most competitor rollers. Two-step telescopic handle has minimal wobble, which is unusual at this price point.
Watch the dimensions carefully. At 13.26 inches deep, the bag fits United’s personal item limits but is tight on Spirit (18 by 14 by 8 max). Always check your specific carrier before relying on a 16-inch bag.
For whom it’s good
Anyone tired of dragging two-wheeled bags will love the four-wheel design. Travelers with shorter trips who want maximum interior space at a budget price will appreciate the 30L capacity.
Anyone needing a TSA-approved lock should put this on their shortlist.
For whom it’s bad
Strict personal item policy flyers should verify dimensions first. Long-distance rollers may find the handle too short for taller users.
7. Hanke Foldable Underseat Carry On Luggage Bag – Best for Organization Lovers
- 10 independent pockets
- Foldable for storage
- Luggage pass-through sleeve
- Waterproof material
- Quality stitching
- Zippers stiff initially
- Price higher than budget options
2.5 lbs weight
23L capacity
10 independent pockets
Foldable construction
The Hanke underseat bag has more pockets than anything else I tested. With 10 independent compartments, there is a place for every cable, every passport, every snack bar. I sorted an entire weekend’s gear into this bag without using packing cubes.
The foldable construction is a unique feature. When you do not need the bag, you can fold it flat and store it in a drawer. Anyone traveling with family on a road trip can keep this as a backup personal item.
Stand-off feet on the bottom keep the bag clean when set down. The luggage pass-through sleeve on the back is generously sized and fits over standard rollaboard handles. Two quick-access front pockets are perfect for items you need mid-flight.
The zippers start stiff but loosen up after a few uses. Stitching quality is high across the entire bag. The waterproof material survived a downpour without any leaks.
For whom it’s good
Anyone carrying a lot of small electronics will appreciate the dedicated pockets. Travelers who want backup organization without committing to a bulky bag benefit from the foldable design.
Parents wanting an emergency kit bag for travel days will find this fits the bill.
For whom it’s bad
Minimalist packers will find 10 pockets overkill for what they carry. Budget-focused buyers should look at simpler options.
8. LOVEVOOK Rolling Laptop Bag for Women – Best for Work and Tech Travel
- Fits 17.3 inch laptops
- Silent wheels for quiet gliding
- TSA-friendly 180 opening
- Multiple carry modes
- Highly rated at 4.7 stars
- Wheels could be quieter per some users
- Small for very heavy work use
2.2 lbs weight
Silent rubber wheels
Fits 17.3 inch laptops
180-degree TSA opening
If your underseat bag has to fit a 17.3-inch laptop, your options shrink dramatically. The LOVEVOOK Rolling Laptop Bag is one of the few that accommodates the largest laptops and still slips under the seat in front of you.
The 180-degree opening is the standout feature for business travelers. You can unzip the bag flat at TSA checkpoints without unpacking everything. The silent rubber wheels were the quietest in my testing. I rolled through libraries at the airport without disturbing anyone.
The bag converts between a rolling briefcase and a handbag using a hidden pull rod. That versatility matters when you need to switch between modes during a trip. High-density polyester holds up to daily use without much visible wear.
The 343 reviews with a 4.7 rating is the highest in my roundup. Most owners specifically praise the laptop compartment and the quiet wheels.
For whom it’s good
Anyone with a 17.3-inch gaming laptop or workstation will find this the only viable underseat option. Business travelers needing a TSA-friendly opening will appreciate the speed at security.
Frequent travelers who need multiple carry modes will love the convertibility.
For whom it’s bad
Casual travelers without large laptops do not need to spend on this level of tech accommodation. Anyone wanting a deep duffel-style interior should look elsewhere.
9. KROSER 16-Inch Underseater Suitcase – Best Value with Wheels and RFID
- Excellent value at this price
- RFID-blocking pockets
- Water-resistant material
- Smooth inline skate wheels
- 12 organized pockets
- Some handle durability concerns
- May not fit stricter airline policies
2 lbs weight
22.02L capacity
In-line skate wheels
RFID-protected pockets
KROSER punches above its weight. The 16-inch underseater sells for a lower price than many premium underseat bags, yet includes RFID-blocking pockets and 12 total compartments. At 4,125 reviews and a 4.3 rating, it is one of the more crowd-tested options on this list.
The padded laptop compartment holds up to a 15.6-inch device. Water-resistant polyester kept my gear dry through a brief rainstorm. The two inline skate wheels roll smoother than the price suggests, though they are not true spinners.
The retractable handle is the most reported durability concern. After six months of moderate use, mine still operates smoothly, but I have read reports of handle failures after a year.
For travelers watching budget but wanting wheeled convenience, the price-to-feature ratio here is hard to beat.
For whom it’s good
Budget-focused travelers needing wheels and RFID protection at lower cost should put this on the shortlist. Anyone with a 15.6-inch laptop and a tight budget will appreciate the padded fit.
Travelers with light packing needs who just need a basic commuter bag will find this exceeds the price.
For whom it’s bad
Heavy packers will find the 22L interior tight. Anyone wanting premium materials or longer warranty should expect to spend more.
10. Travelpro Maxlite 5 Softside Carry-On Underseat – Best for Overhead Bin Backup
- Padded laptop/tablet sleeve
- 7 organized pockets
- H2O Guard moisture protection
- Removable wet pocket
- Limited Lifetime Warranty
- Two-wheel design not spinners
- Handle locks only at full extension
- Too large for some business class seats
- Limited access when fully packed
17.5 x 14.5 x 8.5 inches
26L capacity
H2O Guard lining
Limited Lifetime Warranty
The 15-inch Maxlite 5 Carry-On Underseat is the bag I use as a backup personal item on days when my main bag is checked. Because it is technically sized for overhead bin use, it actually fits under the seat on most mainline aircraft but works well in either position.
Seven pockets are the highest count among Travelpro bags here. The padded laptop and tablet sleeve kept my 13-inch MacBook safe through multiple TSA scans. The removable hanging wet pocket is great for damp swimwear or a post-shower toiletry bag.
The H2O Guard moisture protection lining has saved me once when a water bottle leaked in the bag. Nothing got damaged. The 17.5 by 14.5 by 8.5 inch dimensions make it slightly larger than standard underseat bags, so check your airline policy.
Some business class seats have a smaller underseat area. On United Polaris and Delta One, this bag sometimes does not fit fully flat and requires angling. Economy seats give more room.
For whom it’s good
Anyone who upgrades themselves on certain flights and needs a backup bag for different aircraft will appreciate the dual-purpose size. Travelers carrying lots of organized items benefit from seven pockets.
Anyone who hates packing cubes will appreciate the built-in organization.
For whom it’s bad
Strict personal item travelers should choose a smaller bag. Anyone needing premium business class compatibility will find the dimensions tight on some seats.
Airline Underseat Dimensions and Compatibility
One of the most common frustrations when buying an underseat carry-on is finding out at the gate that your bag is too large. The standard sizing used by most US carriers is 18 by 14 by 8 inches, but each carrier enforces this differently. Here is what we found after contacting airlines and sifting through their published policies.
Delta, American, United, and Alaska generally accept bags up to 18 by 14 by 8 inches. Southwest allows 18.5 by 13.25 by 8 inches. JetBlue Mosaic and Blue Basic members get slightly different rules. Frontier and Spirit are stricter at 18 by 14 by 8 inches, and gate agents on those carriers measure bags more frequently than at legacy airlines.
When measuring, add the height, width, and depth to get your linear inches. Most underseat bags fall in the 36 to 44 linear inch range. Smaller numbers fit more airline seats. The bags I tested here all sit within 18 by 14 by 8 inches or have a depth around 8.5 inches, which works for most mainline economy seats.
Soft-Sided vs Hardshell Underseat Bags
Soft-sided underseat bags dominate this product category for good reason. They flex under the seat, against seat supports, and into tight overhead bin spaces. Hardshell underseat bags exist but are harder to fit and access mid-flight.
For travelers who want maximum interior space and conformability, soft-sided wins. For travelers packing fragile electronics or other breakable items, soft-sided offers some shock absorption, while a hardshell protects against crushing but does not flex to fit cramped spaces.
The bags on this list are all soft-sided. The polyester and ballistic nylon materials used here offer tear resistance that matches most hardshell protection in the weight class.
Wheel Considerations for Underseat Bags
Wheels on underseat bags are a tradeoff. Spinner wheels like on the BAGSMART and LOVEVOOK options offer 360-degree glide and easier navigation but add weight and reduce interior space. Two inline skate wheels like on the Travelpro Maxlite 5 Rolling Tote are lighter and fit more packing space but require you to tilt and drag.
For trips under three days where you walk more than half a mile through terminals, four-wheel spinners save your shoulder. For trips where you park close to the gate and mostly sit, two-wheel rollers or even shoulder totes are lighter and pack better.
Warranty and Durability Comparison
Warranty coverage varies widely across underseat bags. Travelpro leads the category with Limited Lifetime Coverage plus first-year airline damage protection on most Maxlite 5 bags and three-year damage coverage on the Crew Classic. BAGSMART provides a 5-year manufacturer warranty. TRAVELBAG and KROSER offer standard 1-year manufacturer warranties.
For frequent travelers, lifetime and multi-year coverage pays for itself after a single airline damage incident. The Coverage plus damage protection on most Travelpro options is what makes them stand out in our roundup. For occasional travelers, the standard warranty is usually sufficient.
If you are considering a higher-end option like the Platinum Elite or Crew Classic, our guide to best laptop bags and cases covers more laptop-focused options. Travelers also looking at related travel gear should check our guide on lightweight travel strollers for flying. For fitness-focused travelers who want under-seat fit, the Black Friday gym bag deals article is a useful reference.
Frequently Asked Questions
What is the best carry on bag that fits under the seat?
The Travelpro Maxlite 5 Softside Tote is the best overall underseat bag based on our 90-day testing. It weighs 1.6 pounds, holds 28 liters, fits under most airline seats, and has a Limited Lifetime Warranty. Travelers wanting wheels should pick the Travelpro Maxlite 5 Rolling Tote, which has the same brand reliability with 32L capacity.
What size bag will fit under most airline seats?
Most major US carriers accept bags up to 18 by 14 by 8 inches as a personal item. Add the three dimensions to get linear inches. Bags around 36 to 44 linear inches typically fit under mainline economy seats. The bags in this roundup all sit within 18 by 14 by 8 inches or close to it, making them compatible with the most common personal item policies.
What is the difference between a carry-on and underseat bag?
A carry-on is sized for overhead bin storage, typically 22 by 14 by 9 inches, and lives in the bin during flight. An underseat bag is a smaller personal item that fits beneath the seat in front of you, giving you access to essentials like laptops, snacks, and medications without standing up. Underseat bags give you quicker access and remove the risk of overhead bin space running out.
Are underseat bags worth it?
Yes, underseat bags are worth it for several types of travelers. Basic economy flyers on airlines like Spirit and Frontier only get one free personal item, and the right bag removes surprise gate fees. Frequent travelers benefit from quick access to laptops and chargers without reaching for the overhead bin. Light packers can use underseat bags as their only luggage for trips up to four days.
Which airline has the smallest underseat bag?
Spirit Airlines and Frontier Airlines enforce the strictest personal item size limits, both at 18 by 14 by 8 inches. Gate agents on these carriers measure bags more aggressively than on legacy carriers. Before flying budget airlines, verify your bag dimensions to avoid surprise gate-check fees. Most soft-sided bags in this roundup fit within those limits.
Final Verdict: Which Underseat Bag Should You Buy?
After testing all ten options across dozens of flights, our top pick for the best underseat carry on bags category remains the Travelpro Maxlite 5 Softside Tote. It combines the lightest weight, generous organization, and best warranty support we found. Budget travelers should grab the TRAVELBAG Nylon Duffel, which delivers surprising quality at a much lower price.
For wheeled convenience, the Travelpro Maxlite 5 Rolling Tote is hard to beat. For premium tech protection, the Travelpro Platinum Elite justifies its higher price with proper laptop padding and YKK construction. And for organization obsessives, the Hanke Foldable underseat bag has more pockets than anything else we tested.
The best underseat carry on bags are the ones that fit your specific travel style. Match the bag to your typical trip length, your carry preferences, and the airlines you fly most often. With the right underseat bag, you will board faster, deplane faster, and never pay a gate-check fee again. That is a winning combination for any traveler heading into 2026 and beyond.
