Just received an email from NW granting Skymile Gold Medallion, logged in and found the elite status updated. This status is good through 2/2011. I faxed my status match request with documentations three weeks ago to NW. I don't know whether this "one-time" request would be stored in the new DL's system or not.
There's one interesting statement in the email "We do not offer complimentary SkyMiles Platinum Medallion upgrades based on top tier levels with other carriers."
I'm wondering whether to send in additional request for Platinum Medallion after I get 1K next month.
