Their rules are clear about cylinders.. The valve MUST NOT be attached, or the cylinder sealed in any way..
When flying with airlines, I have been removing the valves COMPLETELY and have had no problems. When checking in, the airline will ask what is in the bag and tell them it's dive gear and there are tanks inside but the valves have been completely removed. They seem happy with this. A smile does go along way also.
