Carry on weight limit is only 7 kg on many international flights

Fly Emirates, Qatar Airways, Qantas or Cathay Pacific in economy and your cabin bag can't weigh more than 7 kg, which is about 15.4 pounds. That carry on weight limit catches plenty of Americans off guard, because American, Delta and United don't publish one at all.

The gap matters this holiday season if you're connecting abroad. A roller that rolls straight onto a plane in Chicago can get pulled aside at a gate in Doha or Sydney, weighed, and sent to the hold. Below you'll find the carry on allowed weight for the big international airlines, what the bag itself eats up, and how to check yours at home before you leave.

Carry on weight limit by airline, in kg and pounds

The cleanest roundup we found is Travel Vient's carry-on comparison, updated November 6, 2026, which checks each airline's own policy page. Gulf and Asia-Pacific carriers cluster at 7 kg, while European network airlines run a little higher.

Those figures are for economy. Emirates gives First and Business passengers two carry-ons instead of one, and Singapore Airlines lets you bring one extra small item up to 15.7 x 11.8 x 3.9 inches on top of the 7 kg bag.

Which airlines have no carry on weight restriction?

Most North American airlines police size, not weight. The standard box for a US carry-on is 22 x 14 x 9 inches, and the scale at the gate rarely comes out on a domestic hop.

Budget airlines sell the cabin bag separately

Ryanair's standard fare covers only a personal item of 15.7 x 11.8 x 7.9 inches that fits under the seat. The 10 kg cabin bag is a paid add-on. easyJet works the same way, with a free under-seat bag and a paid large cabin bag, and a 15 kg ceiling across both.

Rule of thumb: if any leg of your trip is on a Gulf or Asia-Pacific airline, pack your cabin bag to 7 kg, or 15.4 pounds, and you'll clear almost every gate check on the list.

Your empty suitcase already eats half the allowance

Here's the part nobody mentions at the store. The Béis Carry-On Roller weighs 8.36 pounds empty, according to Béis's own size and weight guide. Against a 7 kg cap of 15.4 pounds, that leaves you 7.07 pounds, roughly 3.2 kg, for clothes, chargers and shoes.

That's why the frame matters more for the weight limit for a carry on than for a checked bag. Weigh any bag empty before you buy it. If it's already past 8 pounds, you're trading half your packing room for wheels and a shell.

An 8.36 lb roller leaves just 7.07 lb of packing room under a 7 kg cap. The suitcase itself is more than half of what you're allowed to carry on.

Weight limit for a carry on vs a checked bag

The checked bag weight limit at United and Southwest is 50 pounds, or about 22.7 kg, before overweight fees start. That's more than three times the cabin allowance on Emirates. Our guide to the 50-pound luggage weight limit covers the checked side in detail, and the conversions below are the ones worth memorizing.

How to weigh a carry on bag at home

You don't need a luggage scale. A bathroom scale does the job in under a minute if you use the subtraction trick.

For small stuff, a kitchen scale is more precise. Weigh your charger bundle, toiletry kit and spare shoes separately, then use our grams to ounces converter to add them up in whichever unit your airline uses. If your kitchen scale seems off, a nickel will tell you in about two minutes.

Use a phone app when the scale is already packed

Staying with family and nowhere near a scale? Scale for Grams gives an AI estimate from a photo, handy for deciding which items to pull out. Treat it as a first pass, and use a real scale when you're within a pound of the cap.

What an overweight carry on costs you

Missing the cap rarely means leaving the bag behind. It means checking it, and that's where the money goes. On US domestic legs, Southwest charges $45 for a first checked bag on Basic and Choice fares, and United also charges $45 when you prepay. Both are each way, so a round trip doubles to $90.

International gate charges depend on route and fare, so read the operating airline's excess baggage page before you fly. On budget carriers the math is simpler and harsher: the cabin bag is a product you buy, and the cheapest time to buy it is at booking.

Packing to the cap costs nothing. Missing it on a United or Southwest leg can turn a free carry-on into a $45 checked bag each way.

Luggage weight restrictions on connecting trips

On a mixed itinerary, the operating airline sets the rules. Kayak's British Airways guide warns that partner and codeshare flights may have stricter limits than BA's own. So a Dallas to Sydney trip that ends on a Qantas flight should be packed to Qantas's 7 kg, whatever the first leg allows.

Check the baggage weight requirements for every flight number on your booking, not just the airline you bought the ticket from. It takes five minutes and saves an awkward repack on the floor of a foreign terminal.

Hand carry weight limit in premium cabins

Paying more buys more room on some airlines. Emirates gives First and Business passengers two carry-ons, and on British Airways each bag can weigh up to 23 kg as long as you can lift it into the overhead locker without help.

Carry on weight limit questions travelers ask

Do US airlines weigh carry on bags?

American, Delta, United, Southwest and Alaska don't publish a carry-on weight cap. What they enforce is size, usually 22 x 14 x 9 inches, so a heavy bag that fits the sizer is normally fine.

What is the suitcase weight limit for checked bags?

At United and Southwest it's 50 pounds. Southwest charges $100 extra for a bag of 51 to 70 pounds and $200 for 71 to 100 pounds, on top of the standard bag fee. Our luggage weight limit guide has the full fee picture.

Is there a baggage weight limit on British Airways cabin bags?

Kayak puts it at 23 kg, or 51 pounds, per bag, provided you can lift it into the locker yourself. BA allows one cabin bag of 56 x 45 x 25 cm plus a personal item of 40 x 30 x 15 cm on every fare.
