Best Expandable Carry-On (2026)
There is no single “best” expandable carry-on on the official pages we dated November 10, 2026, and we have not used a sizer. Away’s Carry-On Flex is $325, expands 2.25 in, and goes from 41 L to 47 L. Samsonite’s Freeform Carry-On Spinner is $149.99, expands 1 in, and lists official exterior dimensions of 23 × 15 × 9.75 in. Travelpro’s Maxlite 5 21" Expandable Spinner is $148 sale / $160 regular, expands up to 2 in, and is 5.4 lb. TUMI’s Alpha Dual Access Expandable Carry-On is $950, expands up to 2 in, and lists an official expanded depth of 11.0 in. Official maker language in this set repeatedly warns that a fully expanded bag may miss a carrier sizer. This is not a ranked award.

We compared official expandable carry-on pages for Away’s Carry-On Flex, Samsonite’s Freeform Carry-On Spinner, Travelpro’s Maxlite 5 21" Expandable Spinner, and TUMI’s Alpha Dual Access Expandable Carry-On, plus United’s published 9 × 14 × 22 in carry-on limit, all dated November 10, 2026. We have not packed these bags or used a sizer. Official expansion is not a promise that the bag still fits in the bin.

The picks in detail
1. Away The Carry-On Flex
Best for: The largest official expansion in this set (2.25 in) and a published 41–47 L range — if you will still board unexpanded on a strict sizerAway’s official Carry-On Flex page listed $325, 7.9 lb, a 2.25 in (6 cm) wraparound expander, and 41 L unexpanded / 47 L expanded. Official unexpanded Size-block dimensions are 22 × 14.4 × 9.1 in. Official FAQ language says the unexpanded bag is the internationally compliant size and that you may need to check it when fully expanded. Official FAQ also describes the capacity increase as about 10–15%; the same official page’s 41-to-47 L figures are a larger step than 10%. We are citing both official wordings. Included LifetimeCare and 100-day unused returns apply, as written. This is a different SKU from the non-expandable $275 Carry-On.

2. Travelpro Maxlite 5 21" Expandable Carry-On Spinner
Best for: The lowest official sale price in this set, a 5.4 lb official empty weight, and up to 2 in of official expansionTravelpro’s official Maxlite 5 21" Expandable Carry-On Spinner was $148 on sale / $160 regular, 5.4 lb, and 46 L, with official overall dimensions of 23 × 14.5 × 9 in and up to 2 inches of expansion. Official language says a fully expanded bag may not meet airline restrictions or fit a strict sizer. Official height and width already sit over United’s published 22 × 14 in box.

3. Samsonite Freeform Carry-On Spinner
Best for: A 1-inch official expander on a polypropylene hardside, at $149.99Samsonite’s official Freeform Carry-On Spinner was $149.99 (comparison value $219.99), 6.5 lb, with a 1-inch expander and official exterior dimensions of 23 × 15 × 9.75 in — or 9.8 in width on the specifications table of the same page. Official 23 × 15 × 9.75 in already sits over United’s published 22 × 14 × 9 in box on all three sides, before the expander. Official specifications label a Limited 10 Year Global Warranty; the official product page doesn’t spell out detailed warranty terms. Official liter capacity is not listed.
Price (Nov 10, 2026): Official $149.99; 1 in expansion; 6.5 lb; 23 × 15 × 9.75 in, November 10, 2026. Source
Pros
- A listed 1-inch expander and a built-in TSA lock at an official $149.99 price

Best for: Official unexpanded 21.8 × 14.0 × 9.0 in dimensions and dual-access entry — if the official $950 price is acceptableTUMI’s official Alpha Dual Access Expandable Carry-On was $950, with official unexpanded dimensions of 21.8 × 14.0 × 9.0 in, an official expanded depth of 11.0 in, and up to 2 inches of zip expansion.

- A listed 5-year warranty on the official product page
Cons
- Highest official price in this set ($950), and official empty weight is not listed
- Official expanded depth of 11.0 in sits over United’s published 9 in

Also considered
Travelpro’s official Platinum Elite 22" expandable Rollaboard ($390, up to 2 in of expansion, 23 × 14.5 × 9 in overall) is a two-wheel bag, not a spinner, and is compared separately in Travelpro vs Briggs & Riley. Official Delsey category listings include expandable Chatelet Air 2.0 80th-anniversary carry-ons; those are different SKUs from the standard 23-inch Chatelet we measured in Samsonite vs Delsey, and we did not find official expanded dimensions for those anniversary listings in this table.

Away Carry-On vs Carry-On Flex (2026)
These are the same Away carry-on family with one official difference that matters: the Flex adds a wraparound zipper that expands 2.25 in (6 cm), taking capacity from 41 L to 47 L. It costs $325 against $275 for the non-expandable Carry-On, and it weighs 7.9 lb against 7.5 lb. Away’s own Flex FAQ says the unexpanded bag is the internationally compliant size and that you may need to check it when it is fully expanded.
best ofThe Best Carry-On Luggage for Holiday Travel
If you need a bag that matches United’s published 9 × 14 × 22 in limit (wheels and handle included), Monos’ official Carry-On dimensions do. Travelpro’s Maxlite 5 is much lighter and cheaper, and Away’s The Carry-On sits slightly over that published box on two dimensions — confirm with a sizer.
comparisonSamsonite vs Travelpro (2026)
These are both official expandable carry-on spinners, not a two-wheel-to-spinner match. Samsonite’s Freeform Carry-On Spinner was $149.99 on the official U.S. product page checked November 10, 2026 (a $219.99 comparison value is also listed), at 6.5 lb, with official exterior dimensions of 23 × 15 × 9.75 in and a 1-inch expander. Travelpro’s Maxlite 5 21" Expandable Carry-On Spinner was $148 on sale / $160 regular, at 5.4 lb and 46 L, with official overall dimensions of 23 × 14.5 × 9 in and up to 2 inches of expansion. Both official overall heights sit over United’s published 22 × 14 × 9 in box. This is not a sizer test, and official Samsonite depth wording is not identical on the same product page (9.75 in vs 9.8 in).
comparisonAway vs Tumi Carry-On (2026)
These are not price peers. Away’s The Carry-On was $275 on the official product page checked November 10, 2026, at an official Size-block 22 × 14.4 × 9.1 in (the same page’s FAQ lists 21.7 × 14.4 × 9 in) and 7.5 lb / 41 L, with no expander. TUMI’s Alpha Dual Access Expandable Carry-On was $950 on the official U.S. product page checked the same date, at official unexpanded dimensions of 21.8 × 14.0 × 9.0 in and an official expanded depth of 11.0 in. Official TUMI weight is not listed on that product page. This is not a sizer test, and Away’s two official dimension lines are not identical.
guideHardside vs Softside Luggage (2026)
On official pages checked November 10, 2026, Away describes hardside as an impact-resistant polycarbonate shell starting at $275, softside as abrasion- and water-resistant nylon starting at $225, and aluminum as a premium hard shell starting at $625. Monos, which sells polycarbonate and aluminum cases, not a softside line on the official pages we checked, says its German Makrolon polycarbonate flexes under impact and springs back. We compared those written material claims and the conflicting official measurements, not a drop-test scorecard. Confirm dimensions, including wheels, in an airline sizer.
comparisonAway The Carry-On vs The Bigger Carry-On (2026)
The Bigger Carry-On is $20 more and, on Away’s Size block, about an inch taller and wider, with a listed 49 L versus 41 L. Neither official Size block sits fully inside United’s published 9 × 14 × 22 in limit — the Bigger bag misses it by more.
