I just received a match of CO OnePass Gold for my DL Gold Medallion status, good until Feb 2012. I followed the instructions in the first post and had my new status the first business day after I requested it.

I originally got my Gold status on NW and found it incredibly useful and my miles incredibly usable here in Asia (living in Tokyo and Shanghai). I've found my DL Gold status and miles much less useful... I'm moving back to the States and have been looking at one way award flights from PVG to SEA (airfares are sky-high!). DL offered the worst deal at 150k in coach. AA was 75k and UA only 65k, with the nice option of "upgrading" to E+.

Thanks to the folks here for giving me the idea to get a CO match rather than try to for status on UA. This way I should ultimately get both. And still have the chance to match UA status sometime in the future if I need to.
