The personal item is the last free bag on most airlines, and the budget carriers measure it. An underseat bag that is an inch too tall costs more at the gate than the bag did, so the first thing we checked on every pick is its stated size against the common limits: 18 by 14 by 8 inches on Frontier, Spirit and the major carriers’ basic fares, and the slightly smaller sizers some airlines use. We ranked the underseat bags and personal item bags in our fashion catalog by stated dimensions and capacity, wheels or straps, how the pockets are laid out, whether it slides over a suitcase handle, the fabric, and what owners report after a season of flights.
We have not flown with every bag ourselves; the verdicts rest on the published specs and on the owner review history. Prices are not printed because they change daily; every button opens the live Amazon page. For the bag that goes in the overhead bin, our carry-on luggage guide covers 20- and 22-inch spinners, and our travel duffel bags guide covers bigger soft bags.
How we picked
- Stated dimensions. Every pick lists its size, and we quote it, so you can check it against your airline before buying.
- Built to go under a seat. Each bag is sold as an underseater or personal item; 20- and 22-inch carry-ons and checked bags were left out.
- Hands-free carry. Every pick either has wheels or a trolley sleeve that slides over a suitcase handle.
- Pockets that earn their place. Tablet sleeves, shoe compartments, wet pockets and bottle pockets are noted where the maker states them.
- Owner feedback that is consistently positive, and most picks are well-reviewed across many owners.
The picks
Amazon Basics Underseat Carry-On Luggage with Wheels and Handle, 14 Rolling Travel Bag, Fits Overhead Bins, Organized Compartments, Navy
The Amazon Basics underseater is the wheeled personal item that more travelers have bought and rated than any other in our catalog, and the rating is strong. It measures 13.4 by 14.2 by 9.5 inches including the wheels, which clears most personal-item limits and slides into an overhead bin on a full flight, and it rolls on two in-line skate wheels with a four-point lift handle. Inside is a main compartment with four zippered pockets, enough for two days of clothes and a spare pair of shoes, and the front pocket has three slots and a zipper for a passport, phone and cables. A rear sleeve fits over the handle of a larger suitcase for a two-bag trip. The depth is the one number to check against the strictest airline sizers, and two wheels mean it pulls behind you rather than gliding beside you like a spinner. For a weekend trip with no checked bag, it is the default.
- The most-reviewed underseat bag on this page, with a strong owner rating
- Wheels and a lift handle, so it rolls rather than hangs from a shoulder
- Four interior pockets keep chargers, cables and toiletries separate
- Sleeve slides over a bigger suitcase handle
- 9.5 inches deep with wheels; check tight sizers
- Two wheels, so it tilts and pulls rather than spins
- Plain navy looks like everyone else on the carousel
BAGSMART Foldable Travel Bag, 37L Expandable Personal Item Bag, Navy Blue
The BAGSMART 37L is the personal item for people who fly out light and come home heavy. It folds into a 7 by 10 inch pouch that disappears into a suitcase pocket, then unfolds into a full weekender with multiple compartments, soft handles, an adjustable shoulder strap and a trolley sleeve that keeps it on top of a rolling case. The fabric is thick and water-resistant with solid zippers, and a zip-open expandable bottom adds room for souvenirs, shoes or a wet swimsuit. Owners rate it strongly. BAGSMART is honest about the catch: in expanded mode it is no longer personal-item sized, so pack it flat for the flight and expand it once you are through the gate or on the way to a hotel. It has no wheels and no frame, so it is a bag you carry rather than roll. As a second bag or a gym bag that happens to fly, it is the best value here.
- Folds to a 7 x 10 inch pouch for the trip out and opens for the trip home
- Strong owner rating
- Trolley sleeve and shoulder strap for hands-free airports
- Expandable bottom for souvenirs or gym gear
- Not a personal item in expanded mode, as BAGSMART states
- Soft bag with no structure; it slumps when half full
- No wheels
Underseat Carry On Luggage Bag, Lightweight Travel Tote Bag for Travel
The MIAOJIE underseat tote is the bag owners rate most highly on this page, and it is built around the one number budget-airline travelers care about: 16 by 8 by 11 inches, comfortably inside the Spirit and Frontier personal-item box with room to spare for an overstuffed pocket. The 23-liter main compartment takes two or three days of clothes, and seven pockets do the organizing: two front compartments sized for a boarding pass and a 12-inch tablet, a bottle pocket and an umbrella pocket on the sides, and more inside. The Oxford cloth is waterproof and stain-resistant and the shoulder straps adjust. It doubles as a gym bag or a garment bag for a suit. The limits are capacity, since 23 liters is a long weekend and no more, and carry, since there are no wheels and the listing does not mention a trolley sleeve. For the cheapest fare on a short trip, it is the bag that gets through the sizer.
- Best owner rating on this page
- Sized well inside the Spirit and Frontier personal-item limits
- Seven pockets including a 12-inch tablet slot
- Waterproof Oxford cloth
- 23L holds two days, not a week
- No wheels or trolley sleeve stated
- Generic listing name; check the color you are buying
Kenneth Cole REACTION Chelsea Chevron Quilted Luggage, Black, Underseater, 17-Inch Carry On
The Kenneth Cole Chelsea is the underseater that behaves like a small suitcase. It stands 17 by 13 by 9 inches on four multi-directional spinner wheels, so it glides beside you through a terminal rather than dragging behind, and the push-button trolley handle extends to 41 inches, which suits taller travelers. Inside there is a tablet pocket, shoe pockets and garment restraint straps, and the quilted chevron polyester twill with gold zippers reads as a designer bag rather than luggage. A rear trolley tunnel slides over the handle of a bigger case. Owners give it a solid rating, with the usual spinner caveats about wheels on rough pavement. It is five pounds empty and 17 inches tall, so it is the pick to measure against your airline before buying: fine as a personal item on most majors, borderline in the tightest budget-carrier sizers. For a daily commute or a weekend away in style, it is the premium choice.
- Four spinner wheels and a 41-inch handle, the most suitcase-like underseater here
- Tablet pocket, shoe pockets and garment straps inside
- Quilted chevron finish that does not look like a budget bag
- Trolley tunnel fits over a larger suitcase handle
- Solid rather than strong owner rating
- 17 inches tall; check the strictest personal-item sizers
- Five pounds empty, the heaviest here
For Frontier Airlines Personal Item Bag 18x14x8 Travel Duffel Bag Carry on
This is the maximum-size personal item at the minimum price: 17.32 by 13.78 by 7.87 inches, a hair under the 18 by 14 by 8 inch limit that Frontier, Spirit and the basic-economy fares on American, Delta and Southwest enforce, with 30 liters inside, which is more than the tote and nearly as much as the BAGSMART. The nylon is water- and tear-resistant, there is an open front pocket and a zippered back pocket, and that back pocket doubles as a sleeve over a suitcase handle. Owners give it a solid rating, and the critical reviews are about what you would expect at this price: two pockets, no structure, and a bag that looks like a sack until it is full. It also works as a gym, beach or overnight bag. If the goal is to use every inch the airline allows and spend as little as possible doing it, this is the one.
- Cut just inside the 18 x 14 x 8 inch limit, with 30L of space
- Lowest price on this page
- Luggage sleeve for a rolling case
- Nylon that resists water and tears
- Solid rather than strong owner rating
- Two pockets only; no internal organization
- Shapeless when not full
Weekender Bags for Women, Personal Item Travel Bag with Shoes Compartment
This weekender earns its place with the compartment the other soft bags lack: a separate zippered section in the bottom for shoes or dirty laundry, so a pair of trainers never shares space with a clean shirt. It also has a PVC-lined wet pocket for a swimsuit or towel, seven pockets in total, a built-in trolley sleeve and a matching 9.4 by 3 by 6.12 inch toiletry bag in the box. At 18.5 by 14.56 by 8.13 inches it is sized for the standard carry-on-compatible personal item and stows under the seat or overhead; a fraction over the strictest 18 by 14 by 8 box when stuffed, so pack it a little soft for a budget carrier. Owners rate it strongly. It is styled and marketed for women and has no wheels. For a long weekend where shoes and a wash bag need their own place, it is the most organized bag on the page.
- Shoe and laundry compartment keeps dirty things away from clean
- Wet pocket and a matching toiletry bag included
- Trolley sleeve; strong owner rating
- Seven pockets for a week of organization
- Slightly over 18 x 14 x 8 when fully packed; squash it for the sizer
- Styled for women
- No wheels
Underseat Carry On Luggage Bag Airplanes Personal Item Bag - 16 IN Black
This black 16-inch bag is the same design as the MIAOJIE tote at rank three, sold under a listing aimed at the gym as much as the airport, and it is worth its own place because owners rate it strongly and it is often the one in stock. It measures 16 by 8 by 11 inches with 23 liters inside, meets the personal-item limits on the major airlines, and is cut to fit a gym locker, which the listing specifies down to Equinox cabinet dimensions. The seven pockets include two front compartments for a boarding pass and a 12-inch tablet and side pockets for a bottle and an umbrella, the Oxford cloth is waterproof and stain-resistant, and the shoulder straps adjust. Like its navy twin it carries two or three days of clothes, has no wheels, and relies on straps. Buy whichever of the two is cheaper or in the color you want; the bag is the same.
- Same 16 x 8 x 11 inch personal-item footprint as our rank-3 tote
- Sized for gym lockers, including Equinox cabinets
- Strong owner rating
- Waterproof Oxford cloth and seven pockets
- 23L limits it to two or three days
- No wheels
- Fewer reviews than the navy version

Check the size against your airline, not the listing
Every bag here states its dimensions, and the useful habit is to compare them with your airline’s personal-item limit before you buy. The common line is 18 by 14 by 8 inches, used by Frontier, Spirit and the basic-economy fares on the big US carriers; the Frontier-sized bag and the weekender are built to that box, and the 16 by 8 by 11 inch totes sit well inside it. Wheeled bags are trickier because wheels and handles count: the Amazon Basics is 9.5 inches deep including wheels and the Kenneth Cole is 17 inches tall, both fine on most airlines and worth a tape measure against the strictest sizers. Soft bags have one advantage here, which is that a half-full bag squashes into a sizer and a wheeled one does not. If you fly budget carriers often, the tote-style picks are the safe choice; if you fly the majors, the wheeled ones are the comfortable one.
Wheels or straps?
A wheeled underseater like the Amazon Basics or Kenneth Cole saves your shoulder on a long walk between gates and stands up on its own at the gate, at the cost of weight, since wheels and a handle add two to three pounds, and space, since the handle tube runs through the packing area. A strap bag like the BAGSMART, MIAOJIE and Frontier picks weighs almost nothing, folds when empty and uses every inch of its volume, but it hangs from you. The trolley sleeve on most of the soft bags is the compromise: slide it over the handle of a rolling carry-on and both move as one. Do Best Deal readers who travel with a bigger suitcase should choose a soft bag with a sleeve; those who travel with only the personal item should choose wheels.
Pockets, tablets and the two-day rule
A personal item lives at your feet on the plane, so the pockets that matter are the ones you reach without unzipping the whole bag: the Amazon Basics front pocket with three slots, the MIAOJIE and 16-inch totes’ front compartments for a ticket and a 12-inch tablet, the weekender’s wet pocket. Shoe compartments, on the weekender, and tablet pockets, on the Kenneth Cole, are what turn a sack into luggage. Capacity sets the trip length: 23 liters is two or three days, 30 liters is a long weekend, and the BAGSMART’s 37 liters expanded is nearly a week for a light packer. Our packing cubes guide helps any of them hold more, and a cube is the easiest way to keep a soft bag from turning into a tangle.
What size is a personal item on Spirit and Frontier?
Both use 18 x 14 x 8 inches including handles and wheels. The Frontier-sized bag here is cut just under that, the 16 x 8 x 11 inch totes are well inside it, and the weekender is a fraction over when stuffed, so pack it soft.
Does a wheeled underseat bag count as a personal item?
Usually, if it fits the airline size box including wheels and handle. The Amazon Basics at 13.4 x 14.2 x 9.5 inches fits most limits; the Kenneth Cole at 17 x 13 x 9 inches fits most majors but is worth checking on budget carriers.
How much can I pack in an underseat bag?
The 23L totes hold two or three days of clothes; the 30L Frontier bag and the weekender hold a long weekend; the BAGSMART expands to 37L. A pair of shoes takes a third of any of them, which is why the weekender has a separate shoe compartment.
Which underseat bag is best with a rolling suitcase?
Any pick with a trolley sleeve: the Amazon Basics, BAGSMART, Frontier bag, weekender and Kenneth Cole all slide over a suitcase handle so the two move as one.
Is a soft bag or a wheeled bag easier to get under the seat?
A soft bag, because it compresses around the seat supports and the bag in front of it. Wheeled bags are rigid and need the full space, which is tight on regional jets.
