I saw here on Status Matcher that Wyndham wasn't matching status with any external programs but was matching with La Quinta Rewards, which is currently in the process of merging into the Wyndham conglomerate.
I used my Hilton Diamond yesterday to request via email a status match upgrade with La Quinta, and was granted Elite (highest of LQ's 3 levels) in a reply email. The status had already been upgraded when I logged into my LQ account.
I then used Wyndham's online form to request a status match with La Quinta. It was granted literally in only the time it took for the confirmation webpage to load -- about 2 or 3 seconds.
