British Airways allows passengers to bring carry-on items on the plane with them, but they have a weight requirement. Does British Airways weigh them? Here’s what you need to know.

Hand Baggage Weight Limits

British Airways hand baggage must be no bigger than 56 cm x 45 cm x 25 cm and weigh no more than 23 kg. You are allowed an additional personal item that must fit under the seat in front of you. Typically, if the bag meets the size requirements, it will not be weighed unless it is visibly overweight.

You may be asked to test it by slotting it in the guide prior to check-in. If it doesn’t fit, you will need to check it. Additionally, if it is a full flight, you may be asked to weigh it to prevent the flight from being overweight. Your carry-on bag may need to be checked if there is no more space on the flight; however, you will not be charged for this by the airline.

If you only have carry-on luggage and checked in online, it’s unlikely that your hand baggage will be weighed. However, it is always a possibility. To avoid extra baggage fees at the airport, you can weigh your bag before you leave.


British Airways will not typically weigh carry-on luggage unless there is a reason, though there are weight limits in place for a reason. If your bag is weighed and deemed too heavy, you may be subject to additional fees and forced to check your bag.
