This seems to be the most comprehensive thread on status matching with CC, but it hasn't been updated in a while. So I thought I'd provide my recent experience.
I sent an email to
[email protected] with a screen shot of my HH Gold status and received an email back from
[email protected] later the same evening with the following:
"Thank you for providing the documentation for a status match! We have upgraded your Club Carlson account to Gold status effective immediately and expiring on February 28, 2016 (unless otherwise re-obtained). Please review the list of elite benefits below."
Also, I noticed that the
Radisson/Club Carlson page on StatusMatcher gets updated with others' experiences fairly frequently.
