The Samsonite Freeform Carry-On Spinner delivers about 48.7 liters of packing space for its current price of $129.99. That’s roughly $2.67 per liter of capacity. The Away The Carry-On runs $6.71 per liter, and the Monos Carry-On Pro runs $8.19 per liter. If packing space per dollar is your deciding factor, the Freeform wins by a wide margin over both. It isn’t the sturdiest of the three, though. Independent testing found its zipper let water reach the interior. Its polypropylene shell also scratches more easily than the Away or Monos hardshells. So frequent flyers may still prefer one of the pricier two.
I’ve packed a carry-on for enough beach trips and island flights to know one thing. Liters on a spec sheet rarely match what a suitcase actually swallows. A zipper that strains at the last shirt matters more on travel day than any number printed on a box.
Which Carry-On Wins on Capacity Per Dollar?
- Best Overall — Away The Carry-On: $275 for 41 liters of manufacturer-stated capacity ($6.71 per liter), with the strongest resale recognition and build reputation of the three.
- Best Budget — Samsonite Freeform Carry-On Spinner: $129.99 for roughly 48.7 liters, computed from Samsonite’s own published interior dimensions ($2.67 per liter) — the cheapest way to buy carry-on space by a wide margin.
- Best Upgrade — Monos Carry-On Pro: $295 for 36 liters ($8.19 per liter), the lowest capacity per dollar of the three but the only one with a padded 15-inch laptop compartment built into the shell.
Carry-On Capacity Per Dollar: The Full Comparison
We pulled each brand’s own current price and stated capacity. Then we divided price by liters to get a real cost-per-liter figure. That’s the closest thing to an apples-to-apples comparison across three suitcases with very different marketing stories.
| Suitcase | Current Price | Packing Capacity | Price Per Liter | Liters Per Dollar |
|---|---|---|---|---|
| Samsonite Freeform Carry-On Spinner | $129.99 | ~48.7 L (computed from published interior dimensions) | $2.67 | 0.375 L |
| Away The Carry-On | $275.00 | 41 L (Away’s stated capacity) | $6.71 | 0.149 L |
| Monos Carry-On Pro | $295.00 | 36 L (Monos’ stated capacity) | $8.19 | 0.122 L |
Price: What Each Carry-On Costs Right Now
Away’s own product page currently lists The Carry-On at $275. Monos’ own product page lists the Carry-On Pro at $295. That’s a $20 gap that the two brands treat as roughly equivalent positioning. Samsonite’s own site lists the Freeform Carry-On Spinner at a sale price of $129.99, marked down from a $219.99 list price. That’s more than $145 cheaper than Away even before any liter-of-capacity math enters the picture.
Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
That sale-versus-list gap matters for the value math below. Even at Samsonite’s full $219.99 list price, the Freeform still works out to $4.52 per liter. It’s still cheaper than Away and Monos either way, just by a smaller margin than the sale price shows.
Carry-On Capacity Per Dollar: How Many Liters You’re Really Buying
Away states The Carry-On holds 41 liters on its own product page. Monos states the Carry-On Pro holds 36 liters on its own product page, a number Forbes Vetted’s product listing independently repeats. Samsonite does not publish a liter figure for the Freeform Carry-On Spinner on its product page. So we computed one ourselves. At 20.5 x 14.5 x 10 inches of interior space, that’s 2,972.5 cubic inches. That converts to 48.7 liters using the standard 0.0163871-liters-per-cubic-inch conversion.
Here’s one honest caveat. Independent capacity testing from the carry-on review site Pack Hacker measured Away’s real interior volume at 39.8 liters. That’s about 11% below the 41-liter figure on Away’s own product page. Manufacturer-stated liters and independently measured liters don’t always match, on any brand. That’s exactly why this comparison names its source for every number rather than presenting one figure as unquestionable.
Size and Weight: The Real Dimensions Matrix
Liters per dollar only matters if the suitcase actually fits in the overhead bin. So here are the real, manufacturer-published exterior and interior dimensions side by side. They also show how each stacks up against IATA’s cabin-baggage sizing guidance.
| Suitcase | Exterior (H×W×D, in) | Interior (H×W×D, in) | Weight |
|---|---|---|---|
| Away The Carry-On | 21.7 × 14.4 × 9.0 | 20.1 × 13.9 × 7.5 | 7.5 lb |
| Monos Carry-On Pro | 22.0 × 14.0 × 9.0 | not published by Monos | 7.8 lb |
| Samsonite Freeform Carry-On Spinner | 23.0 × 15.0 × 10.0 | 20.5 × 14.5 × 10.0 | 6.5 lb |
IATA’s current cabin-baggage guidance recommends an optimal size of roughly 55 x 35 x 20 cm. That’s about 21.7 x 13.8 x 7.9 inches. It’s a size that clears the large majority of the world’s aircraft bins. None of the three suitcases here actually meets that narrower guideline on depth. All three run 9 to 10 inches deep. That’s standard for the roughly 22 x 14 x 9-inch allowance most major U.S. carriers still enforce. Samsonite’s Freeform is the largest exterior footprint of the three by a full inch on every dimension. That’s a meaningful part of why it holds more.
Is the Cheap Carry-On Worth It on Capacity Per Dollar?
The Samsonite Freeform’s capacity-per-dollar win comes with a real tradeoff, not a hidden one. Independent testing from Outdoor Gear Lab reviewer Jason Wanlass found that the Freeform’s zipper — not its polypropylene shell — is where water actually gets in, with nearly a third of the interior absorbing moisture during a submersion test, and that the lighter polypropylene shell “scratches very easily” compared to the polycarbonate shells Away and Monos both use.
Outdoor Gear Lab’s own verdict is that the Freeform earns a “Best Buy” designation for value but suits “leisure travelers” taking “a handful of trips per year” rather than frequent business travel — an honest, source-named caveat worth weighing against its price advantage. On the warranty side, Away and Monos both advertise lifetime coverage on wheels, handles, and locks, though Forbes Vetted notes Monos charges a $20–$45 return fee that Away does not.
Is Away’s Carry-On Worth More Than Its Capacity Per Dollar?
Away’s suitcases are worth the extra cost mainly for travelers who value name-brand resale recognition and a specific durability track record, not for raw packing capacity, where they place in the middle of this comparison rather than the top. Forbes Vetted senior travel editor Astrid Taran wrote of Away’s larger carry-on that “it features ample packing space while still fitting into most overhead bins, and it has a sturdy zipper that has given me no issues when I’ve packed the bag to the brim” — a direct rebuttal to the kind of zipper failure Outdoor Gear Lab found on the cheaper Samsonite.
At $6.71 per liter, Away sits closer to Monos than to Samsonite on value, which means the case for it has to rest on something other than capacity: build confidence, resale value if you ever sell it secondhand, and simply being the suitcase most airport staff and fellow travelers already recognize.
Monos or Away Carry-On: Which Has Better Capacity Per Dollar?
Monos earns its place over Away mainly for organization and lower brand-collision risk, not for value — at $8.19 per liter it is the most expensive way to buy carry-on space of the three we compared here. Forbes Vetted’s Esther Carlstone wrote that the Carry-On Pro “is surprisingly roomy and can easily fit a week’s worth of clothes. I especially love the exterior pocket for my laptop or iPad… I’ve taken it on dozens of flights and it always fits in the overhead bin.”
Forbes Vetted managing editor Emmy Favilla made a smaller but genuinely practical point in the same comparison: “because everyone seems to have an Away suitcase, I’m less worried about someone accidentally taking my Monos luggage at the carousel.” That’s not a capacity argument, but for travelers who’ve actually had a bag mixed up at baggage claim, it’s a real one.
How Many Liters Do You Need for a Week-Long Trip?
Most travelers packing five to seven days of clothing into a single carry-on need somewhere between 35 and 45 liters, which is exactly the range all three suitcases in this comparison fall into or near. Samsonite’s roughly 48.7 liters gives the most cushion for bulkier items like boots or a jacket; Monos’ 36 liters is the tightest fit and leaves the least room for souvenirs on the way home.
If you regularly pack close to the limit, capacity per dollar becomes more than an abstract number — it’s the difference between a suitcase that zips closed without a fight and one that doesn’t. Pairing any of these three with a set of compression packing cubes can meaningfully increase how much of that stated liter figure you can actually use, since loose folded clothing rarely fills a suitcase’s full geometric volume.
Where Do These Carry-On Numbers Come From?
This comparison is built from each manufacturer’s own current published pricing and dimensions. Away’s, Monos’, and Samsonite’s own product pages were checked in August 2026. We also checked independent reviews and tests from Outdoor Gear Lab, Forbes Vetted, and the carry-on review site Pack Hacker. They’re all named and linked, or cited by name, above wherever we relied on them. Where a brand did not publish a liter figure, we computed one ourselves from that brand’s own stated interior dimensions. We showed the arithmetic rather than estimating a number.

Carry-On Value and Sizing Questions
Is Away luggage worth it?
Away luggage is worth it mainly for its build reputation and resale recognition, not for capacity per dollar — at $6.71 per liter it sits in the middle of this comparison, well behind Samsonite’s Freeform on raw value but ahead of it on independently reported zipper durability.
Is Monos or Away better for a first-time buyer?
Away is the better first-time buy for most people because it costs $20 less than the Monos Carry-On Pro and holds more manufacturer-stated capacity (41 liters versus 36), while Monos’ main edge is a built-in padded laptop compartment that Away’s base model doesn’t include.
How many liters is a standard carry-on suitcase?
A standard carry-on suitcase typically holds between 35 and 45 liters, which covers all three suitcases in this comparison — Monos at 36 liters on the low end, Away at 41, and Samsonite’s Freeform at roughly 48.7 liters computed from its own published interior dimensions.
Does carry-on size include the wheels and handle?
Yes — airline carry-on size limits are measured on the suitcase’s full exterior footprint, wheels and handle included, which is why all three suitcases here list exterior dimensions close to the common 22 x 14 x 9-inch U.S. carrier allowance rather than their smaller interior packing dimensions.
What is the best budget carry-on suitcase in 2026?
The Samsonite Freeform Carry-On Spinner is the best budget carry-on suitcase by capacity-per-dollar math in this comparison, at $129.99 for about 48.7 liters — but independent testing found its zipper is not fully water-resistant, so it suits occasional leisure travel better than frequent flying.
Why is the Samsonite Freeform cheaper than Away and Monos?
The Freeform is cheaper mainly because it uses a lighter polypropylene shell instead of the polycarbonate both Away and Monos use, which Outdoor Gear Lab’s testing found scratches more easily and isn’t rated for the same frequency of use — a real cost tradeoff behind the lower price, not just a discount.
