Yes. If your airline approves you can take spare non-flammable gas cylinders with you in carry-on or checked luggage. These cylinders are commonly used for inflating bicycle tyres.
All cylinders containing pressurised gas present a risk of exploding. It is not safe to take larger cylinders onto the plane.
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.
If you want to retrieve an item that has been removed, please contact your airline as soon as possible. The airline will dispose of items within three to seven days, so the sooner you make contact, the better your chance of having the items returned to you. For more information, see:
