I am going on a scuba-diving holiday. How do I transport equipment such as airtanks and CO2 cartridges for buoyancy aid?
Small non-toxic gas cylinders, for example those used for artificial limbs or in lifejackets, may be carried in the aircraft cabin or in hold baggage. You must check with your carrier as they must approve the carriage of such items. Remember that they must fit into your hand luggage if they are to be taken on to the aircraft. Air tanks for diving cannot be carried.
