How to choose the right carry-on luggage
Updated June 2026Independently researchedNo paid placement.
The best carry-on for 2026 is the one that fits the strictest airline you plan to fly, weighs as little as possible without sacrificing durability, and has the wheel-and-handle setup you find most comfortable. Focus on materials like polycarbonate or ballistic nylon, spinner wheels for smooth rolling, and a telescoping handle with a firm lock. Don’t overpay for brand names, plenty of mid-range options offer the same performance.
What size carry-on should I look for?
Most airlines cap carry-on dimensions around 22 x 14 x 9 inches (including wheels and handles), but low-cost carriers can be tighter at 20 x 14 x 8 inches. If you want a single bag for all travel, aim for a hard-shell that fits the strictest limit you might encounter. Soft-sided bags often have a bit of give, which can help squeeze into a sizer, but they also have external pockets that may push you over. A growing trend in 2026 is the “personal item plus” style bag that is just under the seat limit for European budget airlines. These are usually 18 x 14 x 8 inches or smaller, and many are now designed as hybrid backpacks with a small telescoping handle. If you plan to fly Ryanair or Spirit frequently, that may be your most practical choice.
Hard shell vs soft shell: which is right for you?
Hard-shell bags usually get top marks for protecting fragile items because they distribute impact across the shell. Polycarbonate is the most resilient material, it flexes and springs back, while ABS is harder but more prone to cracking. The trade-off is that a hard-shell leaves you with a single large compartment and often no exterior pocket, so you lose quick-access storage. Soft-sided bags made of ballistic nylon or Cordura absorb shock better than you might think and can be scrunched into overhead bins a bit more easily. They also come with multiple external pockets for a passport, phone, or a water bottle. The main downsides are less crush protection and a handle system that’s usually integrated into the fabric rather than a rigid frame. For many travelers, a quality soft-shell is still the most versatile option.
The importance of weight and maneuverability
Carry-on weight limits vary between airlines from 15 to 22 pounds, so the bag itself should be as light as possible. Lightweight polycarbonate shells can be under 5 pounds, while soft-sided bags with multiple compartments and metal corners run a bit heavier. Every pound of bag weight is a pound you can’t use for your belongings. Four-wheel spinners are now standard on most carry-ons for a reason: they glide beside you and handle uneven surfaces better than two-wheel options. Look for wheels with a rubber-like tread rather than hard plastic, they roll quieter and last longer. The telescoping handle should have a little wobble but lock firmly in multiple positions. A taller adjustment range (from roughly 28 to 40 inches) helps if you’re very tall or very short.
Interior organization features to consider
A good carry-on should help you pack efficiently without forcing you to unpack everything at security. Look for a main compartment with a compression system, either a compression panel or built-in straps, that keeps clothes from shifting. A separate wet or mesh pocket for toiletries can save you from digging through a spill. Some bags include a dedicated shoe compartment that doubles as a dirty laundry sack; others have a removable divider to let you use the bag as a single large cube. If you travel with a suit or dress, a fold-out garment sleeve is a nice touch, but make sure it doesn’t devour too much of the main space. The best interior layouts feel modular, you can rearrange or remove pockets according to your trip.
Durability and warranty: what to expect
The shell material and stitching quality are the first indicators of how long a bag will last. Polycarbonate shells often carry a 5- to 10-year warranty against cracks, while ABS may only get two years. Soft-sided bags should have double-stitched seams and reinforced stress points around the handles and wheels. Corner guards, either plastic or metal, can prevent the most common wear spots. Beyond materials, pay attention to the warranty and repair policy. Some brands offer “no-questions-asked” replacements for the first few years; others expect you to ship the bag back at your own cost. A bag that costs a few hundred dollars with a limited warranty might be a worse long-term value than a budget-friendly model with a strong guarantee. Read user reviews specifically about wheel failure and handle separation, those are the most common failure points.
Should you get a TSA-approved lock?
If you travel to or through the United States, a TSA-approved combination lock is necessary if you want to lock your bag and avoid having the lock cut off. These locks allow security agents to open them with a master key. Most quality carry-ons now include one as a built-in feature, often recessed into the shell or the handle. For international travel outside the US, check local security rules. Some countries use different lock standards, and in some cases a simple zipper pull tab with a cable tie is actually more practical because it shows tampering without requiring a key. If a bag doesn’t come with a built-in lock, you can buy a small keyed TSA padlock that fits through the zipper holes. Just remember to store the key separately from the bag.
Frequently asked questions
Can I bring a carry-on and a personal item together on most airlines?
Yes, nearly all full-service airlines allow one carry-on bag that goes in the overhead bin plus a personal item (like a backpack or purse) that fits under the seat. Low-cost carriers often charge extra for carry-on but still let you bring a small personal item for free.
What happens if my carry-on is too big for the sizer at the gate?
If it doesn’t fit in the sizer at the gate, the airline may force you to check it, often for a fee that can be as high as a few tens of dollars. To avoid that, measure your bag’s full height including wheels and compare it to the strictest dimensions of the airlines you fly most.
Are four-wheel spinner bags always better than two-wheel inline bags?
Spinners are easier to roll through flat airport terminals and on smooth floors, but they can roll away on an angled train or bus. Two-wheel bags are more stable on rough surfaces and tend to have stronger wheels, but they require you to tilt and pull them. Your choice should match your typical terrain.
Do I really need a polycarbonate shell, or is ABS fine?
Polycarbonate is lighter and more flexible, meaning it resists cracking better over time. ABS is fine for occasional travel or on a tight budget, but it can become brittle in cold temperatures and may crack after a few hard impacts. If you travel frequently, spend a little more on polycarbonate.
What about battery packs built into carry-on luggage?
Batteries built into the bag must comply with airline regulations (usually under 100 Wh). The bag should let you remove the battery without tools, because if it’s non-removable, security may not allow it on the plane. Check the manufacturer’s rating carefully before buying a powered bag.
Is a garment bag a better choice for business travelers?
A dedicated garment bag that folds in half to carry-on size can keep suits wrinkle-free, but often lacks space for shoes or toiletries. Many travelers are better off with a regular carry-on that has a built-in suiter compartment, which offers more flexibility for mixed trips.
