The right carry on luggage fits your airline’s cabin rules and leaves enough weight allowance for your belongings. Compare the full outside measurements, wheels, handle, shell and interior before choosing a case.

The right bag depends on your route and how you travel. A lighter case can be easier to lift, while expansion and divided compartments can help you organize a longer trip.

For quick comparisons, start with our guides to carry-on luggage size, carry-on luggage weight limits and how to pack a carry-on suitcase.

How do you choose carry on luggage?

Choose carry on luggage by checking the airline’s rules first, then comparing size, weight, wheels, shell and storage. A bag that looks compact in a product name can still exceed a limit once you count its wheels and handles.

Measure the exact bag’s outside dimensions, including wheels and handles. Airlines set their own cabin limits, and rules can differ across airlines on the same trip, so check every carrier you’ll use.

If you want a step-by-step shortlist, see our guide to how to choose carry-on luggage. The key decision is whether the bag fits your flight and your usual packing habits.

What size carry-on should you buy?

Buy a carry-on that stays within the size limit for your flight, including protruding wheels and handles. There is no single size that works for every airline.

A bag described as 20 or 21 inches may refer to the case size or a rounded product name. Compare its full outside dimensions with your airline’s published limit, and check whether the bag expands.

The Travelpro Maxlite Air V2 20-Inch Carry-On measures 23 x 14.5 x 9.5 in overall, including wheels and handles. Those dimensions show why width and depth matter as much as height.

Samsonite gives conflicting outside measurements for the Samsonite Freeform 21-Inch Carry-On and Samsonite Omni PC 20-Inch Carry-On, so confirm the exact dimensions before ordering either. The Omni PC’s weight also needs confirmation, and the Stratum 2.0’s shell material is unclear.

Check the airline’s size rules again before travel, especially when your trip includes more than one carrier. Our carry-on luggage size guide explains how to compare measurements and what to include.

How much should a carry-on weigh?

A carry-on should be light enough for you to lift when packed and stay within your airline’s weight limit, if it has one. The empty bag’s weight uses part of your packing allowance.

The Samsonite Freeform 21-Inch Carry-On weighs 6.5 lb, the Travelpro Maxlite Air V2 20-Inch Carry-On weighs 6.7 lb, and the American Tourister Stratum 2.0 Carry-On weighs 7.3 lb. That spread is less than a pound, but it can matter if you pack heavy items.

Samsonite gives both 6.1 lb and 6.81 lb for the Samsonite Omni PC 20-Inch Carry-On. Don’t use it as the lightest option in your comparison until its weight is clear.

Include the case, clothes, toiletries and other packed items when weighing your carry-on. A light empty shell won’t keep an overpacked bag within a strict allowance.

Check your airline’s current weight rules, since they can vary by carrier and route. For a closer look at how the limits work, read carry-on luggage weight limits.

Are spinner wheels worth it?

Spinner wheels are useful if you want a case that can roll beside you and turn in tight spaces. Two-wheel bags are pulled behind you, while spinner designs can move in more directions.

Wheel count doesn’t tell the whole story. Check the handle’s height and grip, the bag’s weight and the surfaces where you’ll roll it, such as terminal floors or uneven sidewalks.

The Samsonite Freeform 21-Inch Carry-On and Travelpro Maxlite Air V2 20-Inch Carry-On each have 8 wheels. The Samsonite Omni PC 20-Inch Carry-On and American Tourister Stratum 2.0 Carry-On each have 4.

The Freeform’s 8 wheels form 4 dual-wheel spinner assemblies. Count both the individual wheels and their layout when comparing designs, rather than assuming a larger number means better handling.

For a plain explanation of the wheel layouts, see what spinner luggage is. Choose the setup you’ll find easier to manage when the bag is full.

Should you choose hardside or softside luggage?

Choose hardside luggage if you prefer a firm outer shell, and consider softside luggage if a more flexible bag fits your packing style. Material and construction vary by model, so compare each case rather than relying on the category name.

All 4 examples in this guide have hard shells. The Samsonite Freeform 21-Inch Carry-On uses polypropylene, while the Samsonite Omni PC 20-Inch Carry-On and Travelpro Maxlite Air V2 20-Inch Carry-On use polycarbonate.

The American Tourister Stratum 2.0 Carry-On has a textured hard shell. American Tourister describes it as both ABS and polycarbonate, so its exact material remains uncertain.

Samsonite describes the Freeform’s exterior and the Omni PC’s micro-diamond texture as scratch-resistant. Scratch resistance doesn’t mean a case will stay free of marks or damage.

A hard shell doesn’t make a bag damage-proof. For more on the trade-offs, read hardside vs softside luggage and hardside luggage: pros, cons and what to look for.

What interior features help with packing?

Interior dividers, pockets and straps help keep clothes and small items arranged inside a carry-on. Look at the layout and expansion feature alongside the bag’s outside size.

The Samsonite Freeform 21-Inch Carry-On has elastic straps, a divider and a pouch. Those features give you separate places for packed items without relying on one open compartment.

The American Tourister Stratum 2.0 Carry-On has a modesty pocket, mesh door pocket and elastic tie tapes. The Travelpro Maxlite Air V2 20-Inch Carry-On has 2 zippered divider panels with pockets.

The Stratum 2.0 expands by 1 in, while the Maxlite Air V2 expands by 2 in. The Freeform and Omni PC also have expandable designs, but no expansion depth is given here.

Expansion can add room, but it may make a bag too large for a cabin sizer. Pack it to the size you plan to carry and measure it before relying on that extra space.

Our carry-on packing guide shows how to use the interior efficiently. If you need a larger case for part of the trip, compare carry-on vs checked luggage before you book.

Which carry-on luggage options fit different needs?

The Samsonite Freeform 21-Inch Carry-On has the highest site score among these options, while the other cases offer different packing layouts and expansion features. Start with airline fit, then compare the features you’ll use.

Our scores weigh specs and features against what you’re shopping for. They aren’t results from personal use.

Samsonite Freeform 21-Inch Carry-On

The Samsonite Freeform 21-Inch Carry-On combines a 6.5 lb weight with a polypropylene shell and 8 wheels. Its score is 9.1, the highest of these 4 options.

Its interior gives you a divider and pouch for separating items. Choose it if that organization suits your packing style and its confirmed outside dimensions fit your flight.

Samsonite describes its textured exterior as scratch-resistant. The expandable design adds flexibility for packing, but check the packed size before using that extra room on a flight.

Samsonite Omni PC 20-Inch Carry-On

The Samsonite Omni PC 20-Inch Carry-On pairs a polycarbonate shell with 4 spinner wheels, an expansion gusset and a TSA lock. Its score is 8.7.

Samsonite describes the micro-diamond texture as scratch-resistant. That texture may appeal if you want a patterned exterior, but it doesn’t make the shell immune to wear.

Its conflicting weight and outside measurements make those figures less useful for a close airline-fit comparison. Choose it for its shell and expansion features only after resolving those measurements.

American Tourister Stratum 2.0 Carry-On

The American Tourister Stratum 2.0 Carry-On is a 7.3 lb hardside case with 4 wheels and 1 in of expansion. Its score is 8.5.

Its dimensions are 15 x 9.5 x 22 in. Check that these measurements cover all protruding parts before comparing them with a strict cabin limit.

The interior includes a modesty pocket, mesh door pocket and elastic tie tapes. Consider it if those compartments suit your packing needs, and measure it expanded if you plan to use the extra room.

Travelpro Maxlite Air V2 20-Inch Carry-On

The Travelpro Maxlite Air V2 20-Inch Carry-On offers 2 in of expansion and 2 zippered divider panels with pockets. Its score is 8.2.

It weighs 6.7 lb and measures 23 x 14.5 x 9.5 in overall, including wheels and handles. Compare that full size with your airline’s cabin rules before choosing it.

The shell is polycarbonate, and Travelpro says it flexes on impact to help reduce cracking. Its adjustable PowerScope Lite handle and 8 spinner wheels give you specific features to compare with the other cases.

How can you compare carry-ons without relying on the name?

Compare outside measurements, empty weight, materials and storage for each model. Names like “20-inch” and “21-inch” can be shorthand, so use confirmed dimensions to check fit.

Dimensions follow each brand’s order, so compare the actual height, width and depth rather than the table order. The Travelpro measurements explicitly include wheels and handles.

Keep uncertain measurements out of close fit calculations. A small difference can affect whether a packed case stays within your carrier’s limit.

What should you check before buying carry-on luggage?

Check your airline’s size and weight rules, the bag’s full outside measurements, and whether the packed case will be manageable for you. Then choose the shell, wheels and interior features that match your trip.

Use this checklist:

1. Airline fit: Compare all outside dimensions with your carrier’s cabin limit.
2. Weight: Check the empty bag weight and any airline weight cap.
3. Expansion: Measure the expanded case if you expect to use the extra room.
4. Wheels and handle: Choose a layout and grip you can manage in a crowd.
5. Storage: Look for dividers, pockets and straps that match what you pack.
6. Trip length: Decide whether a carry-on holds what you need, or if checked luggage makes more sense.

For international trips or routes with multiple airlines, confirm the rules with each carrier before departure. A bag that fits one flight may not meet another carrier’s size or weight limit.

Which carry-on luggage should you choose?

Choose the Samsonite Freeform 21-Inch Carry-On for its 6.5 lb weight and divided interior, or the Samsonite Omni PC 20-Inch Carry-On for its textured polycarbonate shell and expansion gusset. Confirm their measurements before deciding on airline fit.

Choose the American Tourister Stratum 2.0 Carry-On if its pockets and 1 in expansion suit your packing habits. Pick the Travelpro Maxlite Air V2 20-Inch Carry-On if you want 2 zippered divider panels and 2 in of expansion.

Before you decide on carry on luggage, use the carry-on size guide to compare the packed case with your airline’s rules.

External guidance for carry-on rules

Your airline sets cabin baggage size and weight rules, so check its baggage page for the flight you’re taking. Airline rules can change, and each carrier on a connecting trip may have different limits.

The TSA carry-on guidance explains what you can bring through security. Security screening rules are a separate check from whether your case fits the airline’s cabin allowance.

Frequently asked questions

What should I look for in carry on luggage?

Start with the airline’s size limit, then compare the bag’s full outside dimensions, including wheels and handles. Check its empty weight, wheel layout, shell material, interior dividers and expansion feature to judge whether it will fit your trip and be manageable in the cabin.

Are 4-wheel spinner carry-ons better?

Four-wheel spinners can roll beside you and turn in multiple directions, which can help in busy terminals. Wheel count alone doesn’t show how well a bag will suit you, so also consider handle comfort, packed weight and how the wheels affect the full outside dimensions.

Do carry-on bags have a weight limit?

Some airlines set a carry-on weight limit, while others focus on size or require you to lift the bag into an overhead bin. Check the airline’s current baggage page for your flight, since rules vary by airline and route, and count the bag’s own weight toward your allowance.

Is hardside or softside carry-on luggage better?

Hardside luggage gives you a firm shell, while softside luggage may offer a more flexible exterior. Your choice depends on how you pack, what you want to protect and whether you value expansion or outside pockets, so compare each bag’s materials and layout before deciding.
