Interesting. Apparently the threshold to get the match with United was raised. I was/am Platinum but United is no longer giving me Silver status. When I tried to register I received the following message: "You must be a Platinum Premier Elite member or above to qualify for RewardsPlus." I got the match last year as a Plat, not a PPE. Oh well, it was nice.
Here are some details:
