How to choose the right carry-on luggage

Updated June 2026Independently researchedNo paid placement.

What size carry-on actually fits on a plane?

Airlines set their own size limits, and they vary more than many travelers expect. For US carriers like Delta, American, and United, the typical maximum is 22 x 14 x 9 inches (including wheels and handles). Budget airlines in Europe and Asia often enforce smaller limits – around 21.5 x 15.5 x 9 inches for some, or even as low as 18 x 14 x 8 inches. Always check the specific airline before you buy. Many carry-on bags marketed as “full-size” hover around the 22-inch mark. A bag that is even a half-inch too tall can be flagged at the gate on some low-cost carriers. If you fly multiple airlines, a slightly shorter bag (21 to 21.5 inches) gives you more leeway, though it may sacrifice a small amount of internal volume.

Hard shell vs soft shell: which is better?

Hard-shell bags have become the most popular choice for their sleek look and protection. Polycarbonate shells – found on models from Samsonite and Away – are lighter and more impact-resistant than ABS plastic, which can crack under stress. Hard shells keep contents safe from crushing, but they don’t expand, and their rigid sides can make it harder to overpack into odd spaces. Soft-shell bags, like those from Travelpro or Briggs & Riley, compress and bulge slightly to fit overhead bins better when full. They typically offer more external pockets for quick access to documents, chargers, or a water bottle. The trade-off is less outright impact protection and a look that some find less modern. For travelers who carry a laptop or fragile items, a hard shell with a separate laptop compartment in the front panel (like the Travelpro Platinum Elite soft-side actually does) can bridge the gap.

Spinner vs two-wheel: which rolls best?

Four-wheel spinners dominate the market for good reason: they roll smoothly in any direction, stay upright when you let go, and reduce wrist strain in wide aisles. High-quality spinners from brands like Samsonite or Delsey use spinner wheels that don’t wobble or jam – a common issue with cheaper bags. On uneven pavement, carpet, or gravel, two-wheel (inline skate) bags are actually more stable and easier to pull behind you. They also don’t tip over as readily when the bag is heavily loaded. If you mostly navigate smooth airport floors and city sidewalks, a spinner is the obvious choice. If you take trains, walk cobblestone streets, or roll through snow and slush, a two-wheel bag may be more reliable. Some manufacturers, like Briggs & Riley, offer both styles within the same line so you can pick based on your routes.

How important is weight and material?

A carry-on that’s too heavy limits how much you can pack without exceeding airline weight limits (often 10kg / 22 lbs). Lightweight polycarbonate or ballistic nylon (like on Travelpro’s Maxlite series) can shave off a pound or two compared to ABS or cheaper fabrics. But weight savings sometimes come at the cost of durability – very thin polycarbonate can dent or crack if the bag is dropped onto a hard edge. Look for “ballistic” or “Cordura” nylon for soft-side durability, or multi-layer polycarbonate for hard shells. The handle mechanism and telescoping handle tubes should feel sturdy; wobbly handles are a common failure point. For most travelers, a bag weighing under 7.5 pounds (empty) is a good target, but don’t sacrifice build quality just to hit a number.

What features actually make a difference?

A built-in lock (TSA-approved) is convenient, especially on hard-shell bags where the zipper can be locked. Expandable sides are useful on soft-shell bags, but be careful – expanding may make the bag too large for overhead bins. Look for a compressible expansion that works like a zipper to flatten when not needed. Interior organization – like packing cubes, a separate wet pocket, or a tie-down strap – can save time and keep your clothes neat. Wheel quality matters more than many think. Large, quiet rollerblade-style wheels with a smooth bearing feel are worth paying extra for. Handle height should match your height; most telescoping handles stop around 40 inches, but some brands offer taller options for very tall travelers. A fabric exterior with a “DuraGuard” or similar coating resists water better than plain nylon, though no soft-side is fully waterproof.

Does a budget carry-on work as well as a premium one?

Yes and no. Bags in the budget-friendly range (typically from brands like AmazonBasics or lower-tier Samsonite) use lighter ABS plastic or thinner nylon, and the wheels and handles often wear out faster. A bag that costs a few hundred dollars from Travelpro, Briggs & Riley, or Tumi will usually offer a better warranty (some are lifetime), sturdier telescoping handles, and wheels that roll quietly after years of use. For occasional travel (2–4 trips a year), a budget bag can be perfectly fine. If you fly often or need reliability, the mid-range and premium options pay off over time. Another trade-off: premium bags tend to be less flashy and more functional, while budget bags often try to imitate trendy designs with lesser hardware. The sweet spot for most people is a well-reviewed mid-range model from a brand with a strong reputation (Samsonite, Travelpro, Delsey) – you get quality without the luxury markup.
