Carry-on bag
Checked-in luggage
Non-flammable gas

Can I take this item on a plane?

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.

What are the restrictions?

  • A limit of four cylinders
  • Each cylinder must not exceed 50ml
  • Must be Division 2.2 gas
  • Your airline must approve carriage

Why is this item restricted?

All cylinders containing pressurised gas present a risk of exploding. It is not safe to take larger cylinders onto the plane.

What happens if I have a restricted item in my carry-on bag?

You will be asked to relinquish all dangerous or prohibited items found in your carry-on luggage. If you refuse:

  • you will not be permitted to move through the screening point, and
  • your airline will be advised of your refusal.

How does Aviation Security screen for restricted items?

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.

What if my items are removed?

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:
