Almost every US airline holds carry-on bags to the same box. That box is 22 x 14 x 9 inches, wheels and handle included. Most European carriers use a smaller box, 55 x 40 x 20 cm.
Finding the best carry-on luggage starts with the box you fly against, not the brand on the shell. This guide sorts the best carry-on luggage by class. Budget hardside, mid price, premium, softside, international size and travel backpack.
Check the carry-on size chart against your own airline first.
Start with the box, not the brand
A US domestic carry-on box is 22 x 14 x 9 inches. Add an inch of wheel housing, and a hardside can measure legal on a tape at home. It can still get stopped at a strict gate sizer.
European low-cost carriers commonly cap the free cabin bag at 55 x 40 x 20 cm. Some, including Ryanair, weigh it too. A bag built for the US box often runs an inch or two too tall for that one.
Measure with the wheels down and the handle up, since that is how a gate agent measures it. TSA confirms there is no federal size rule, only each airline’s own box.
What separates a good carry-on from a bad one
Empty weight matters almost as much as size. A heavy shell eats into the checked bag allowance you never get. It also eats into the personal item weight some airlines now enforce.
Wheel quality and zipper durability are what reviews complain about first. A lifetime warranty that covers airline damage, not just factory defects, matters more than a spec sheet. It is the feature that separates a bag you replace every trip from one you keep for a decade.
- Budget hardside: lightest on price, thinnest on shell, fine for a few trips a year.
- Mid price hardside: the volume sellers most travelers actually own.
- Premium hardside or softside: a heavier price tag, backed by a real warranty.
- International size: cut an inch or two smaller for the tighter European box.
- Travel backpack: no wheels, no sizer argument, useful when stairs beat a rolling case.
Compare the classes
| Product | Class | What reviews say | Best for |
|---|---|---|---|
| Amazon Basics 20 inch hardside spinner | Budget hardside | Over 62,000 ratings at 4.4 stars. Reviewers call it fine for occasional trips, not weekly flying. | A once or twice a year traveler on a tight budget |
| Samsonite Omni PC 20 inch hardside spinner | Mid price hardside | Samsonite’s hardside with the most reviews on Amazon. Reviewers flag it as sized for the US box, not the European one. | A domestic flyer who wants the most reviewed, safest default |
| Travelpro Platinum Elite 21 inch hardside | Premium hardside | Reviewers repeatedly say it is the case flight crews buy. Heavier than a Maxlite, but tougher. | A frequent flyer who wants durability over minimum weight |
| Briggs & Riley Baseline Essential 22 inch carry-on spinner | Premium softside | The priciest bag on this list, backed by a guarantee that repairs the bag for life. Airline damage included. | A traveler who wants to buy one carry-on and stop shopping |
| Travelpro Maxlite 5 21 inch softside carry-on spinner | Budget softside | Reviewers buy it for airlines that cap weight. The expansion zip pushes it past most size boxes when open. | A traveler on a weight limited budget carrier |
| Samsonite Freeform 21 inch hardside carry-on | International size, lightweight | Samsonite’s lightest hardside carry-on. Reviewers pick it when a European airline weighs the cabin bag. | A flyer whose airline caps weight, not just size |
| Delsey Paris Helium Aero 19 inch international carry-on | International size | Built smaller than the US box on purpose. Reviewers who fly Europe or Asia rate it above the bigger Delsey models. | A traveler who mostly flies outside the US |
| Osprey Farpoint 40 travel backpack | Travel backpack | 40 liters with a harness that stows for the sizer. Reviewers rate the clamshell opening above a pack that loads from the top. | A traveler who wants both hands free and no wheels to drag |
By budget
If price is the only filter, look at the Amazon Basics 20 inch hardside spinner. It carries tens of thousands of reviews. It costs less than most airlines’ checked bag fee for one trip.
It will not survive a decade of monthly travel, and reviewers say so. For a twice a year traveler, it does the job. One step up sits the American Tourister Stratum 2.0 20 inch, from the Samsonite family.
Its shell runs thinner than the Omni PC’s. Either bag clears the US box, but neither is built for rough handling in the hold.
By mid price
The Samsonite Omni PC 20 inch hardside spinner carries more reviews than any other hardside on Amazon. It is sized for the US domestic box, priced in the middle of the market. Reviewers who fly Europe say it runs close to the tighter box; measure first.
The Travelers Club Chicago 20 inch hardside carry-on sits at a similar price with a similar review count. Owners rate it well for the first few years, less so past that. Once you own a case, packing it well matters as much as the shell.
By premium
The Travelpro Platinum Elite 21 inch hardside is the line flight crews buy for themselves, per the manufacturer. Reviewers echo that it survives rough handling better than lighter cases. It weighs more empty than a budget shell, and that matters on a route that caps weight.
Read more in the Travelpro Platinum Elite writeup. The Briggs & Riley Baseline Essential 22 inch carry-on spinner costs more than any other bag here. Its guarantee is the reason.
Among the best carry-on luggage on this page, it is the one built to be repaired rather than replaced. According to the manufacturer’s own guarantee page, Briggs & Riley repairs functional damage for life, airline damage included, at no charge.
It does not cover cosmetic scuffs, lost contents, or damage from improper storage. Read the terms before you assume every scenario is covered.
By softside
A softside carry-on flexes to fit an oddly shaped overhead bin better than a hard shell. The Travelpro Maxlite 5 21 inch softside carry-on spinner is the budget pick reviewers choose for airlines that cap weight. Its empty weight runs lighter than most hardsides.
Its expansion zipper is the catch. Unzipped, reviewers note it grows past most size boxes, so keep it closed at the gate. The Delsey Paris Sky Max 2.0 21 inch softside carry-on spinner sits between the Maxlite and the Platinum Elite softside on price.
It adds a front laptop pocket reviewers use at security.
By international size
A bag built for 22 x 14 x 9 inches is not automatically legal on a European carrier’s 55 x 40 x 20 cm box. The Delsey Paris Helium Aero 19 inch international carry-on is cut smaller on purpose. Reviewers who fly Europe and Asia rate it higher than Delsey’s US sized models.
The Samsonite Freeform 21 inch hardside carry-on is Samsonite’s lightest hardside. That matters more than an inch of height on airlines that weigh the cabin bag rather than measure it. Check the carrier’s own box on the European carry-on size page first.
By travel backpack
A backpack skips the sizer argument entirely. There are no wheels adding height, and a soft frame compresses under a gate template. The Osprey Farpoint 40 travel backpack measures 21.7 x 13.8 x 9.1 inches per the manufacturer, close to the US box, at 3.27 pounds empty.
Its full clamshell opening is what reviewers praise over a pack that loads from the top. It lays flat like a suitcase instead of making you dig from above. A harness that stows away keeps straps from catching on a conveyor or a gate template.
Not sure whether a backpack counts as your carry-on or your personal item? This breakdown settles it by airline.
Whichever class you land on, weigh the bag empty before you pack it. The carry-on size chart confirms the box, and only a scale confirms the weight. See the carry-on weight limit page for which carriers actually enforce one.
The bottom line
For most US domestic flyers, the Samsonite Omni PC remains the safest default among the best carry-on luggage here. It carries more reviews than any hardside on this page. It is priced in the middle and sized for the standard box.
A flyer who travels weekly, or checks a bag through rough handling, should look past the sticker price. The Briggs & Riley Baseline Essential costs more up front. Its guarantee outlasts several cheaper bags bought back to back.
Skip the budget hardside class if you fly more than a handful of trips a year. The thin shells that keep the price down are the first thing reviewers say fail. Skip any bag sized for the US box if your next flight weighs the cabin bag instead of measuring it.
