After 14 trips across Europe, Southeast Asia, and the US in 2026 — here's our full verdict on the Away Flex Carry-On. Read our testing methodology.
Luggage & Travel Gear Editor · Tested across 14 trips, Jan–June 2026 · Methodology
Away launched the Flex Carry-On in late 2024 as the brand's answer to a question frequent travellers had been asking for years: can you have a hardshell carry-on that flexes when your packing outgrows its dimensions? The answer, after 14 trips across three continents with this bag in tow, is a confident yes — with a few caveats worth knowing before you spend $295. The Flex Carry-On sits in Away's lineup between the classic The Carry-On ($275) and the Aluminium Carry-On ($695), and it's the model most travellers should choose as their daily driver.
The expandable shell mechanism is the defining feature and it works exactly as advertised. A zip runs around the midline of the bag; unlatch it, pull the two halves apart, and you gain 1.75 inches of additional depth — enough to pack a couple of extra days' worth of clothing or squeeze in the souvenirs you definitely didn't plan on buying. Crucially, the bag fits standard overhead bins in both configurations on all 14 flights we tested it on, including the notoriously tight overhead compartments on regional jets. The polycarbonate shell itself is 20% thicker than the previous generation and resisted scuffs well across airport carousel use — minor abrasion marks after 14 trips, none that break the surface.
The built-in battery continues to be one of Away's smartest differentiators. The 10,000 mAh ejectable pack charges via USB-C, and the bag itself exposes a USB-A and a USB-C port on the exterior — you charge your phone from the bag's exterior, then pop the battery out at security in about two seconds. Over 14 trips, the battery charged a modern smartphone approximately 2.5 times on a full charge. One note: airlines require the battery to be removed and carried in the cabin during flight, which is standard IATA compliance — Away's ejection mechanism makes this effortless versus competitors who hide the battery under a flap requiring a screwdriver.
The spinner wheels are genuinely excellent. Away uses a dual-bearing system on all four 360° wheels, and after 14 trips — including cobblestone streets in Lisbon, tiled platforms in Tokyo's metro, and the eternally punishing floors of JFK's Terminal 4 — not a single wheel cracked, loosened, or started dragging. This is not guaranteed across all luggage at this price point; we've had wheel failures on Samsonite and Tumi bags in under half the mileage. The TSA-approved combination lock is embedded in the zipper pull and reset to a custom code in under a minute — no lost keys, no broken locks across any tested trip.
The honest caveats: the Flex Carry-On weighs 7.3 lbs unladen, which is heavier than softside competition like the Monos Carry-On Pro (6.7 lbs) and meaningfully heavier than ultralight picks like the Calpak Hue (5.2 lbs). If you're on carriers with strict 15 lb carry-on limits, the weight of the bag itself eats into your allowance more than we'd like. The interior compression pads are effective but not adjustable — you either use them or remove them, there's no middle setting. And at $295, the Flex Carry-On is a premium buy; the equally-excellent Away Carry-On Classic at $275 is only $20 cheaper but lacks the expansion feature, so the $20 premium for the Flex is clearly worth it. We named the Flex Carry-On our Best Carry-On Luggage of 2026 in our Best Travel Gear Awards. Browse our full luggage reviews or the carry-on category.
Scored across our 5-dimension luggage rubric — read our testing methodology for how we calculate weighted scores.
20% thicker polycarbonate shell, dual-bearing spinner wheels, and embedded TSA lock all performed flawlessly across 14 trips — zero failures or repairs needed.
1.75" expansion adds meaningful volume; 39.8L collapsed to 45.7L expanded. Compression pads and laundry bag included. Fits overhead bins in both configurations.
10,000 mAh USB-A + USB-C ejectable battery is the easiest to remove at security of any tested bag. Charges a smartphone 2.5x. Charges via USB-C in under 2 hours.
Four 360° dual-bearing spinner wheels rolled smoothly across cobblestones, metro platforms, and airport terminals. Zero drag or rattle after 14 trips.
At $295, pricier than some rivals, but the lifetime warranty, built-in battery, and expansion feature justify the premium over comparable hardshell carry-ons at this tier.

Everything you need to know before buying the Away Flex Carry-On.
Yes — and this was one of the most important things we tested. Across all 14 flights in our evaluation period, the Flex Carry-On fit in overhead bins whether collapsed (9" deep) or fully expanded (10.75" deep). The key is that the expansion adds depth front-to-back, not height or width — so the bag's footprint in the overhead compartment stays within standard bin dimensions. That said, ultra-compact regional jets with restrictive bins (common on some European budget carriers) can be tight when expanded. We recommend collapsing the bag before boarding on smaller aircraft to be safe.
The FAA carry-on size limit is typically 22" × 14" × 9" — the Flex Carry-On's expanded depth of 10.75" exceeds this, but in practice the TSA and airlines measure at check-in using the bag's nominal size, and Away.com lists the collapsed dimensions for compliance purposes. When in doubt on strict carriers, keep the bag collapsed.
Yes, with one important step: the battery must be ejected from the bag and carried in the cabin during flight — it cannot be in a bag going into the cargo hold (which is irrelevant for carry-on but matters if you check it). The IATA regulation covering lithium-ion batteries under 100Wh (which includes Away's 10,000 mAh / 37Wh pack) permits them in carry-on only, not checked luggage.
Away's ejection mechanism is the fastest of any smart luggage we tested: press the button on the battery housing and it slides straight out — no flaps, no screws, no fumbling. At security, you pop it out, drop it in the tray with your laptop, and slide it back in after the checkpoint. The whole process takes under 10 seconds once you've done it once.
Note that a very small number of international carriers have blanket bans on smart luggage batteries in cabins regardless of size. Check with your specific airline if travelling to or through jurisdictions with stricter rules (some Middle Eastern carriers and a handful of South Asian routes have applied this in the past).
Away's lifetime warranty covers all functional components of the bag — wheels, handles, zippers, locks, hinges, and the shell itself — against defects and breakage for the lifetime of the original purchaser. It does not cover cosmetic damage like scratches, dents from normal use, or airline damage (for which you'd file a claim with the airline separately).
To make a warranty claim, you register at Away.com (the warranty card in the box has a QR code), then contact Away support with a photo of the damage. In our experience testing the process with a cracked wheel housing on a previous Away model, replacement parts arrived within 5 business days at no charge. Away also has repair partners in major cities for in-person service. The key caveat: the warranty applies to the original purchaser — it doesn't transfer if you buy second-hand.
The Flex Carry-On ($295) is worth the $20 premium over the Carry-On Classic ($275) in almost every scenario, because the expansion zip is genuinely useful and the weight difference is negligible (7.3 vs 7.1 lbs). The Classic does not have the expansion feature. Both have the same battery, same wheels, same lock, same warranty, and the same exterior dimensions when collapsed.
Choose the Classic only if you are extremely weight-sensitive (the 0.2 lb saving matters to you) or if you want a marginally cleaner exterior look — the Flex has the expansion zip seam running around its midline which some people dislike aesthetically. For everyone else, the Flex's extra packing flexibility makes it the smarter long-term buy.
Away offers a 100-day trial on all luggage purchased directly from Away.com or Away retail stores. If you're not satisfied for any reason within 100 days of purchase, you can return the bag for a full refund — even if it's been used. Away provides a prepaid return shipping label, so the return is genuinely free. The 100-day clock starts on the date of delivery, not the date of purchase.
The trial does not apply to items bought from third-party retailers like Amazon or Nordstrom — those are subject to each retailer's own return policy (Amazon's is 30 days for most items; Nordstrom's is effectively unlimited). If you want the 100-day trial protection, buy direct from Away. We tested the return process on a previous Away bag and the refund appeared within 5 business days of the carrier scan.
Yes — it's one of the best hardshell carry-ons for international travel, and this is exactly the context we tested it in most extensively. Across 14 trips including cobblestone streets in Lisbon, metro tiled platforms in Tokyo and Singapore, airport terminals in six countries, and a range of airline types from full-service to low-cost, the bag performed without a single functional failure.
A few international-specific notes: (1) the TSA combination lock is TSA-approved, which matters for US-origin flights but is irrelevant for international legs where TSA doesn't have master keys — Away's lock still works as a deterrent and combination lock for those trips; (2) European budget carriers like Ryanair and easyJet have cabin bag size restrictions that are more restrictive than US domestic allowances — the Flex Carry-On may need to be gate-checked on some Ryanair routes if it doesn't meet their 55×40×20cm limit (the bag is 21.7"H which converts to 55.1cm, within range but on the edge); (3) the battery must be removed and carried on your person for international connecting flights where the bag goes below — always eject before checking.
