How to choose the right carry-on luggage

Updated June 2026Independently researchedNo paid placement.

What size carry-on is allowed on most airlines?

Most major airlines worldwide accept a carry-on bag that fits in the overhead bin, typically with a maximum linear dimension of 45 inches (length + width + depth). The most common size limit is 22 x 14 x 9 inches, though some budget carriers enforce stricter dimensions, such as 21.5 x 13.5 x 7.5 inches. Always check the specific airline you fly most often before buying. A smart strategy is to choose a bag that meets the strictest common limit, around 22 x 14 x 9. while also being expandable for airlines with more generous allowances. Many manufacturers now design carry-ons that are officially “international-sized” to fit both budget and full-service carriers. If you frequently fly on ultra-low-cost airlines, consider a “personal item” sized bag that fits under the seat instead.

Hardside vs softside: which is better for you?

Hardside luggage, usually made of polycarbonate or ABS plastic, offers excellent protection for fragile items and is easier to wipe clean. It also tends to be a bit heavier but more rigid, and many models come with a built-in TSA lock. The trade-off is less external stretch: packing a hardside bag to the brim means you lose the ability to add last-minute souvenirs without overstuffing. Softside bags, typically ballistic nylon or polyester, are lighter, more flexible, and often have external pockets for quick access to items like a laptop or passport. They can also squeeze into tight overhead bins more easily. The main drawbacks are less crush protection and a tendency to show wear over time. For business travelers who pack suits or dress shirts, softside with a garment folder is a classic choice. Frequent leisure travelers who pack delicate cameras or gifts often prefer hardside.

What type of wheels and handle should I look for?

Spinner wheels (four multi-directional wheels) have become the standard because they roll smoothly upright and make navigating crowded aisles effortless. Look for wheels made of rubber or soft durometer polyurethane, they absorb vibration and make less noise on hard floors. Ideally, the wheel bearings are sealed to keep lint and hair from jamming the mechanism. A telescoping handle should have a sturdy, wobble-free grip when fully extended. Handles with multiple locking heights are helpful for travelers of different heights. The most common handle material is aircraft-grade aluminum, which offers a good strength-to-weight ratio. Avoid handles that feel loose or have sharp edges during a test roll at the store. Two-wheeled inline skate wheels are still found on some rollaboards and are great for stairs or rough surfaces, but they require tilting the bag and can strain your wrist over long distances.

How important is the interior organization?

Interior organization can make or break a trip. A simple, single-compartment design with compression straps gives you the most packing flexibility, allowing you to use packing cubes or folders as you see fit. Some bags feature a zippered divider that separates dirty or bulky shoes from clean clothes. Look for a tie-down strap system that keeps your items from shifting during travel. For those who prefer built-in compartments, consider a carry-on with a separate zippered pocket for toiletries or a wet pack pocket. A suiter or garment folder flap is a nice addition if you carry dress clothes. However, too many small pockets can eat into usable space. The best approach is to decide on your packing style, using cubes vs. free-stuffing, and choose a bag that complements that method rather than forcing you to adapt to its layout.

What should I know about warranty and durability?

Warranty length and coverage are strong indicators of a brand’s confidence in its luggage. Premium brands offer lifetime warranties that cover damage from airlines and manufacturing defects, while budget-friendly options often provide only a one-year limited warranty. If you travel frequently or check your bag often, a more generous warranty can save you hundreds in repairs or replacements. Durability involves more than warranty: check the zipper quality (YKK or similar brass zippers are a good sign), the handle pull-test, and the corner reinforcements. Hardside polycarbonate shells with a textured or multi-layer finish resist scratches better than glossy ones. Reinforced corner bumpers on softside bags help protect against the most common wear points.
