Carry-on luggage weight limits depend on the airline, route and fare. Check the rules for every flight before you pack, since a bag accepted on one leg may not meet another carrier's allowance.

A carry-on's own weight counts toward the total. Weigh the packed bag, not just the items you put in it, and check the size rules too with our guide to carry-on luggage size.

Do airlines have a carry-on luggage weight limit?

Some airlines set a carry-on weight limit, while others focus on bag dimensions or use different rules by route and fare. There isn't one weight allowance that applies to every flight.

Check the airline's baggage page or your booking details for the cabin-bag weight and size rules. For a trip with more than one carrier, check each airline separately, including the airline operating a connecting flight.

A general carry-on luggage buying guide can help you choose a bag, but the airline's own policy determines what you can bring on your flight.

Where can you check the weight allowance?

Find the carry-on allowance in your airline's baggage rules or booking details. Look for the rules for your exact route and fare, since policies can differ across services.

Check these details before packing:

• Maximum weight for the carry-on bag, if one is set.
• Whether a personal item has a separate or shared allowance.
• Maximum bag dimensions, including wheels and handles.
• Whether the rule changes for a particular route or fare.
• The policy for each airline on a connecting itinerary.

Airline policies can change, so use the current rules for your trip rather than a number remembered from an earlier flight. If a policy isn't clear, contact the airline before departure.

How do you weigh a carry-on at home?

Weigh the entire packed carry-on, including the suitcase, wheels and anything inside it. If your airline sets a limit, compare that total with its stated allowance.

A hanging luggage scale gives you a direct reading for a packed bag. The travel inspira Digital Luggage Scale has a backlit display, a data-lock function and capacity up to 110 lb.

The BAGAIL Digital Luggage Scale also has a backlit LCD, auto data lock and capacity up to 110 lb. It includes a metal hook and nylon strap for weighing a suitcase.

To use either scale, secure the bag as directed and lift steadily until the reading settles. Keep the bag close to the floor while weighing it, and follow the scale's instructions.

If you don't have a luggage scale, weigh yourself on a household scale, then weigh yourself again while holding the bag. Subtract the first reading from the second for an estimate.

A hanging scale made for luggage may be easier to use for repeated checks. Leave some room below the airline's limit rather than relying on a reading right at the cutoff.

Does suitcase weight leave room for your packing?

Yes. A heavier empty suitcase leaves less allowance for your belongings, because the bag itself contributes to the carry-on's total weight.

Compare the empty weight of bags you're considering, but also check their exterior dimensions against your airline's limit. The Samsonite Freeform 21-Inch Carry-On weighs 6.5 lb and has a polypropylene shell.

The Samsonite Omni PC 20-Inch Carry-On has a polycarbonate shell and expands for extra packing space. Extra space doesn't increase your airline's weight allowance, so weigh the bag again after adding more items.

Measure and weigh the exact bag you'll take, including its wheels and handles when checking size. Neither a carry-on model name nor extra packing space establishes that a suitcase meets your flight's rules.

Our guide to standard luggage sizes explains common suitcase dimensions, while lightweight carry-on luggage covers more bag options.

What should you do if your carry-on is too heavy?

Remove or redistribute items before you leave for the airport if the packed bag exceeds your airline's stated limit. Reweigh it after each change so you know whether it's within the allowance.

Start with heavy items you can move to a personal item or checked bag, if the airline allows it. Keep essential documents, medicine and valuables accessible, and check baggage restrictions before moving batteries or electronics into a checked bag.

If you can't get the bag within the allowance, contact the airline about your options before arriving at the airport. The available choices and any charges depend on the carrier and itinerary.

Can a personal item help with an overweight carry-on?

A personal item can help redistribute belongings only when the airline permits it and the item meets its separate rules. Some carriers count cabin items together, so moving weight may not change the total allowance.

Check the personal-item dimensions and any weight rule before moving items. Keep the item small enough to fit where the airline requires, such as under the seat, if that is part of its policy.

How can you pack to stay within the limit?

Pack only what you'll use, then weigh the complete bag before you leave. A short packing list can help you remove duplicates and avoid adding last-minute items.

Put heavier essentials in the bag with the most available allowance, while following the airline's limits for every item. Don't assume that a personal item can hold unlimited weight, and check security rules for anything you plan to carry onboard.

For a step-by-step packing method, see how to pack a carry-on suitcase. Reweigh after packing is finished, including any chargers, toiletries and items added at the last minute.

Carry-on weight limits: what should you remember?

Choose a lighter suitcase if empty-bag weight is using too much of your carry-on allowance, and remove belongings if your current bag is still too heavy. Moving items to a personal item helps only when the airline allows separate weight allowances.

Frequently asked questions

Do all airlines have a carry-on weight limit?

No. Carry-on weight rules vary by airline, route and fare, and some airlines focus on size instead, so check the baggage rules for every airline on your itinerary, including connecting carriers, and confirm whether your personal item shares the allowance.

How do I know if my carry-on is overweight?

Check your airline's maximum carry-on weight, then weigh the packed bag with a luggage scale or a household scale. Include the bag itself and everything inside it, compare the total with the airline's stated limit, and reweigh after adding any last-minute items.

Does a personal item count toward the carry-on weight limit?

It depends on the airline's rules. Some rules set a combined allowance for cabin bags, while others give separate limits or focus on size, so check the policy for both bags before moving items between your carry-on and personal item.

What happens if my carry-on is over the weight limit?

The airline may ask you to move items, check the bag or pay a fee, depending on its rules and the flight. Reduce the weight before you reach the gate when possible, and keep important items accessible in case the bag must be checked.
