Wow - sure is a lot of emotion flying around this thread.
Here are a few free suggestions (worth every penny) from someone inside one of the "goat-roping" agencies. (Thanks to Mike McDaniel for that ego boost.)
1. If you are following the currently published regulations when traveling with the air cylinder, have a printed hard copy with you. (Try
http://www.tsa.gov/public/display?theme=178) The TSA is concerned both about explosive transport and a rupturing compressed cylinder when exposed to decreased atmospheric pressure.
2. There appear to be two partially applicable code sections for air cylinders, one for "Paintball" and one for "Scuba." In both cases, the cylinder must be (1) disconnected from the regulator, and (2) have an open end. It is arguable that the regulator stays attached to the gun when the cylinder is disconnected and that screwing in the bleeder attachment gives it an open end. (Otherwise the air wouldn't get out.) The only sticking point is that the code calls for "visual inspection" by the screener. The codes were originally written for scuba tank valves and paintball cannisters, and not PCP air guns which are not designed with routinely opening an end in mind.
3. There doesn't seem to be an exact fit of the regulations and some spotty interpretations by screeners, so here are some suggestions to increase the chances of getting the cylinder on the plane:
Drain the cylinders, detach from the gun, and leave the bleeder valve attached.
Declare it a firearm, and tag in accordance with those regs.
If the screener still balks after a calm explanation, BE POLITE, and ask to speak with the Ground Security Coordinator (GSC). Every airport has one - They are the ones in charge of all things in security including the TSA folks, and are there to resolve disputes. They are (by and large) intelligent, friendly, and straightforward. Explain the situation POLITELY, and show that you are informed of the rules, and have followed the regs to the best of your ability. If still denied, ask for recommended solutions or how THEY would get to a match.
Of course, calling or visiting the GSC at your local airport in advance will greatly help things along.
Obviously, this is not a perfect solution but some movement is being made to get the applicable code sections straightened out. Until then, I hope this helps at least ONE person get to a match.
