They made an exception for life vest inflator CO2 cartridges. Bike CO2 is prohibited in carry on and in checked baggage. It's been that way for many years. Purchase a CO2 at the expo or race bike support or a local bike shop.
That article dated 2014 - is this "rule" just US related? I've flown international since that date & only restriction was you couldn't place in carry-on's (obvious). Flown across US too, in/out LAX & never had an issue.
You think a tiny CO2 canister is going to cause a problem in a hold? I doubt it but hey....
edit to add: I've seen this 'rule' used by bike store retailers & race expo organisers.
If its an official airline safety regulation then it'd be good to know.
