Most countries allow for you to bring 1 inflatable PFD on board in a carry-on or in checked bags per person. Two CO2 cartridges/cylinders are permitted inserted into the PFD, plus two spare cartridges/cylinders. While this is in the regulations, the final decision rests with the officer on whether an item is allowed through the checkpoint.

CHECK YOUR AIR CARRIER AND CONNECTING AIR CARRIER’S WEBSITE: They may ban CO2 Cylinders; They may allow them in checked baggage only; or, They may allow them as carry-on and checked baggage.
