The problem is that there are no "rules" regarding status matches, they are at the airlines' discretion. And I can tell you that in order to get a status match, in most cases, you need to provide proof of flying history on the other airline that you are using to claim your match on CO. If your status on that other airline was comped, and you can't provide supporting documentation of any flying activity, I can guarantee you with near-100% certainty that CO will NOT match status. Don't waste your time.
