The FAA is cautioning cabin and cockpit crewmembers to guard against passengers attempting to bring personal oxygen bottles on board an aircraft. Contained O2 is considered a hazardous material both as a non-flammable gas and an oxidizer.

However, these carriers are not allowed to permit passengers to bring their own oxygen tanks aboard.
