What to Do If Your Carry-On Is Over the Weight Limit
Published How we research
Many travellers only think about carry-on dimensions, but a growing number of airlines, especially budget and international carriers, also enforce weight limits. Being told your bag is too heavy at the gate can mean fees or checking a bag you wanted to keep with you.

Know the real limits
Carry-on weight limits vary widely, from around 7 kg on many budget and international airlines to no published limit on some US carriers. Some airlines combine the carry-on and personal item into one total allowance.
Check the specific airline and fare class for every flight on your route. Codeshare and connecting flights can apply the stricter carrier's rules.
Weigh at home
A small digital luggage scale is the easiest way to avoid surprises. Weigh the bag fully packed, including the items you plan to carry on the day, and aim to be a little under the limit.
Remember that shopping and souvenirs add weight on the return trip. Leave some margin or plan to ship or wear new purchases.
Move weight you can carry on your body
If your bag is overweight at check-in, move dense items like chargers, power banks, books and toiletries into jacket pockets or a travel vest. Wear your heaviest shoes, jacket and layers.
A packable daypack or tote folded inside your bag can become your personal item if the airline allows one, spreading weight between two bags.
Pack lighter from the start
Choose a lightweight bag, since some carry-on backpacks weigh 1.5-2 kg empty. Swap bulky toiletries for solid or sheet versions, carry one multi-port charger and use e-books instead of paper.
Pack for about a week and plan to do laundry. Merino and quick-dry fabrics let you bring fewer items that still stay fresh.
If you must check it
Remove passports, medication, valuables, power banks and anything fragile before handing over the bag. Lithium power banks are not allowed in checked luggage.
Keep essentials for the first night, such as a change of clothes and toiletries, in your personal item in case the checked bag is delayed.
Know how enforcement works
Airlines tend to check carry-on weight at check-in desks, bag drop and boarding gates, and enforcement varies by airport, route and how full the flight is. Budget carriers and international flights with small limits enforce most consistently, and staff often weigh bags that look full or strain the traveller carrying them.
Paying for extra carry-on allowance or a checked bag online before the trip is usually much cheaper than paying at the gate. If you are close to the limit, compare the cost of adding allowance in advance with the risk of a gate fee.
