The Best Underseat Luggage and Personal-Item Bags

I’ve covered bags and luggage for Wirecutter since 2014. In that time, I’ve assessed hundreds of bags, ranging from carry-on luggage to travel backpacks to duffle bags. I’ve talked to bag designers, luggage experts, and people who make a life (and sometimes a living) as world travelers. For this article, we also looked at underseat size regulations for the major domestic airlines.

At its most basic, a personal-item bag is a carry-on bag that you can stuff under the seat in front of you while on a flight—which is why it’s sometimes called underseat luggage. Although we wanted to find bags that maximize your available underseat space, airlines generally aren’t as forthcoming with their underseat dimensions as they are with their overhead-bin restrictions. And personal-item sizes, once you do find them, usually differ from one airline to another:

Air Canada: 17 by 13 by 6 inches
Alaska: not specified
Allegiant: 16 by 15 by 7 inches
American: 18 by 14 by 8 inches
Breeze: 17 by 13 by 8 inches
Delta: 22 by 15 by 9 inches
Frontier: 18 by 14 by 8 inches
JetBlue: 17 by 13 by 8 inches
Southwest: 16.25 by 13.5 by 8 inches
Spirit: 18 by 14 by 8 inches
United: 17 by 10 by 9 inches

After checking with 12 airlines, we found that the average size of a personal-item bag is roughly 18 by 14 by 8 inches. If your bag isn’t rigid and comes close to these measurements, you’re probably going to be okay stuffing it under the seat in front of you. If you really want to be sure your underseat luggage will fit, the best way is to call ahead and confirm the underseat dimensions for your flight.

Similar to carry-on luggage, underseat luggage is subject to size and shape requirements. However, unlike most of the things people fly with—nearly all of which are precisely designed for airplane use—almost any small bag (your favorite backpack or tote, for instance) can work as a personal item. That said, there are a few details that separate a great personal-item bag from an ordinary one. Beyond it being just the right size, we’ve found that a personal item should have a few key design details to really stand out.

• Durability: A personal-item bag will spend a bunch of time sitting on an airplane floor, an unappealing resting place of shoe grime, spilled liquids, and lost snacks. It’s important that a bag is made of material that’s both resistant to abrasion and easy to clean.
• Organization: As more airlines begin to introduce Basic Economy tickets, which often restrict travelers to personal items only, having a bag that can mimic some of the capacity and organization of a carry-on becomes increasingly important. We prefer a variety of pockets, ideally a separate laptop compartment, and some kind of water-bottle holder.
• Multiple carrying options: Some underseat luggage pieces designed with air travel in mind have sleeves that you can slide over the rails of carry-on luggage handles. But other carrying options, like backpack straps, shoulder straps, or side handles, can also facilitate easy maneuverability.

Lots of luggage manufacturers now sell bags specifically labeled “personal items,” and some of these have useful features that you might not find in your average backpack or tote bag (more on that later). Still, if you have a bag that already works for you, stick with it. If not, check out our picks below, but also look at the recommendations in our guides to laptop backpacks (most of which will fit under a seat), to duffles (ditto), and any of the picks in our guides to packable daypacks and tote bags. One of those might work just as well for you as a made-for-the-purpose personal item.

For this guide, of those bags specifically designed to be personal items, we looked for models from reputable brands that we’ve recommended in the past, that meet the average underseat dimensions, and that have the traits to make it a great personal-item bag. Then we chose bags that offered different features to suit multiple types of travel scenarios and preferences.

We have a wheeled-bag pick for people who prefer to roll their bag behind them. We have picks that carry like totes. Some of the bags we chose have pass-through straps to loop over the handles of your carry-on luggage. Though this last feature can help you manage the load of a suitcase and a bag, several luggage designers I’ve talked to over the years have said that one of the most common ways to break a carry-on is to rest something too heavy across the telescoping handles. Though they’re able to pull a decent weight, these handles are not designed to support large or heavy loads across their narrow frames. With this in mind, we have options for travelers who prefer pass-through straps as well as those who don’t.

Who it’s for: The Travelpro Crew VersaPack Rolling Tote’s small squat form sits on two wheels, which makes it a remarkably maneuverable case for anyone who doesn’t prefer (or is unable) to carry their personal item on their shoulder or back. The Crew Tote also mounts well to the handles of a carry-on suitcase with a pass-through strap that’s held tight with Velcro.

Why it’s great for travel: The compact Crew Tote is large enough to carry everything you need for an overnight trip but still falls within the average US airline underseat dimensions. However, if you catch a seat with an underseat power bank or any other kind of obstruction, you won’t be able to wedge this case into place like you might be able to do with a soft bag or backpack. That said, the internal frame, wrapped in nylon fabric similar to soft-sided carry-on luggage, should endure plenty of accidental kicks and scuffs. That reinforcement is particularly useful if you’re packing delicate items, such as cameras, extra computer equipment, or fragile gifts.

We’ve recommended Travelpro Platinum Elite luggage for years in our carry-on and checked suitcases guides because of its durability, dependability, and lifetime warranty (that also protects against airline damage for the first three years). Like those other Travelpro picks, the Crew Tote meets the same standards in materials, build quality, and guarantee.

Pockets and organization: The Crew Tote has one main compartment, as well as a front pocket for small papers and tickets. The main compartment of the Crew Tote is built and organized like a small piece of carry-on luggage, with rolling wheels and internal, zippered organizational compartments, combined with some aspects useful in a personal item, such as a padded sleeve (it holds up to a 14-inch laptop) and a pass-through sleeve. The tote is also compatible with Travelpro’s customizable packing-cube system (video), which we discuss in the Competition section of our packing cubes guide.

Flaws but not dealbreakers: As with any rolling luggage, you lose a little packing space to the handle and wheel carriage. The rigid shape of the Crew Tote means there’s very little wiggle room if, for whatever reason, it doesn’t fit under the seat in front of you. Despite the inclusion of a small, exterior, flexible pocket—nominally for an umbrella or water bottle—we found that it was too small to be of much use for anything except a very narrow plastic water bottle.

Who it’s for: The Waterfield Air Porter Carry-On Bag is a high-end personal item made for air travel. But the bag truly shines as a tech organizer that still has enough room to also hold a change of clothes. Plus, it’s good-looking enough to carry from the plane to the boardroom without raising an eyebrow.

Why it’s great for travel: The Waterfield Air Porter has a pass-through strap you can attach to a wheeled-suitcase handle, and like our other picks, the bag fits well under an airline seat. In addition to the waterproof waxed-canvas exterior, which makes the bag easy to wipe off if it comes out from under the seat looking dusty or spilled-on, Waterfield bags have waterproof exterior zippers and water-resistant interior lining. The Air Porter is built to look better with age, while also keeping your stuff safe from the elements and stress of travel. In addition to the pass-through strap, the bag has handles (so you can carry it like a briefcase) and a removable shoulder strap, which keeps it from getting caught on things while it’s stowed away.

Waterfield also makes an Air Caddy to hold your tablet and cables. If you don’t already have a tech organizer, I recommend it. The Air Caddy is as well built as the Air Porter, plus it fits nicely inside the bag and matches the overall look. (Unfortunately, Waterfield no longer offers a discount for bundling in an Air Caddy when you buy the Air Porter.)

Pockets and organization: The bag is split into two compartments. One half has a built-in padded sleeve for a 15-inch laptop and two pockets for tech accessories (including wires, headphones, and charging components), both of which are large enough to hold a battery pack for on-the-go charging. The other half is the larger compartment, with plenty of small interior pockets to assist you in organizing things like a few small pieces of clothing or a toiletry kit. The Air Porter also has a front expanding pocket, with magnets that keep the flap closed whether the pocket’s empty or full. It’s a great feature if you often travel with magazines and books. On either side, the Air Porter has two expanding sleeves for holding a travel umbrella and a water bottle.

Flaws but not dealbreakers: The Air Porter is our priciest pick, but considering the quality of the materials and craftsmanship, we think it’s worth the price—this bag will last a lifetime if cared for properly. We do wish it were a little larger so you could take full advantage of the space available at your feet. Waterfield has a 30-day return policy with no restocking fee, but you will have to cover return shipping costs. Additionally, Waterfield offers a lifetime warranty for any product defects.

Who it’s for: The Away Everywhere Bag feels aggressively designed to offend absolutely no one. It is the true neutral of all personal items, with plenty of carrying options and as many organization options as our other picks. If you want a personal item that’s both simple and well-organized and similar to a weekend duffle bag or large tote (with enough space for a spare outfit, toiletry bag, and a laptop), this is an excellent pick.

Why it’s great for travel: The Everywhere Bag is made of water- and abrasion-resistant nylon, which is perfect for the floor of an airplane. The bag also has a removable shoulder strap, and like most of our other picks, it includes a sleeve for slipping over the handles of a carry-on suitcase, which makes it convenient to carry atop your luggage.

Pockets and organization: The interior features six slim pockets and a sleeve large enough for a 15-inch laptop. At the base of the bag, there’s a zippered waterproof pocket for an umbrella. Outside the bag is a single slim pocket, well-shaped for tickets and important travel documents. Otherwise, the bag opens into a larger interior pocket, which is enough to hold a change of clothes, a toiletry kit, and a book or magazine. If you’re flying for just an overnight trip, this could easily be the only bag you need to carry. (The bag comes in two versions: Original, which has a main zipper that extends partway down the ends of the bag, and New, which has a main zipper that extends all the way down each end of the bag, providing a larger opening.)

Flaws but not dealbreakers: Without any interior separation, all your gear is mashed together along with your computer and tech. There isn’t a special pocket for a water bottle, which means if you carry one, it is dangerously close to everything else.

Who it’s for: The Longchamp Le Pliage Tote is great if you need an adaptable personal item that can easily double as a purse or work bag as soon as you leave the plane. Unlike many bags made to be this tough, the Longchamp is handsome and looks good enough to easily transition from travel bag to daily carry.

Why it’s great for travel: The lightweight (especially compared with leather bags) Le Pliage Tote shines as a travel bag because of its simple, packable design and practical materials. The nylon construction wipes down easily if spilled on, and you can fold it down and pack it away if you want to consolidate down to one bag on any leg of your trip.

The Le Pliage’s shoulder strap is made of rolled leather, which our tester said kept the strap from biting into their shoulder as much as unrolled leather straps can. Its main compartment is large enough to hold a laptop, sweatshirt, water bottle, and other assorted travel items. It zips shut, so you won’t lose anything even as you stuff it underneath your seat. The understated shape and design of the bag also blends in nicely with both professional and casual outfits.

Pockets and organization: There is one modest pocket on top for your phone, wallet, and keys. However, we found that even this pocket felt a touch small.

Flaws but not dealbreakers: For a bag that’s great for taking right from the plane to the office, we wished for a laptop compartment, or some other way to separate items beyond the single top pocket. In our testing, we ended up organizing the tote ourselves with bag organizers. The Le Pliage lacks a pass-through strap or slot for attaching to the handles of your carry-on luggage.

Dimensions: 12.25 by 11.75 by 7.5 inches
Weight: 0.7 pounds
Capacity: 17 liters

Cotopaxi Nazca 24L Travel Pack: The clamshell design of this backpack, a former pick in this guide, was perfect for anyone who liked to separate their gear into individual pockets and compartments. The bag was well made, shaped to fit under just about any airline seat, and warrantied for a lifetime of travel. Sadly, it’s been discontinued.
