All scissors with blades of more than 6cm in length, measured from the fulcrum, are restricted from carry-on luggage but they can go in your checked-in luggage.
If you do not need scissors during the flight pack them in checked luggage or leave them at home.
These items can used as weapons and can cause harm to passengers and crew.
You will be asked to relinquish all dangerous or prohibited items found in your carry-on luggage. If you refuse:
AvSec x-ray bags going onto aircraft to ensure there is nothing dangerous in them. If something comes up on the x-ray that needs checking, the bag will be opened, searched and any dangerous good or prohibited item will be removed, with a bag search notification form left within the bag.
