Since it is a matching program, I think I'm good on United until Feb 2002. That is the duration for my current Platinum status. I haven't received the info from United in the mail, but they put me in the system the day I asked and I was able to get a decent seat the next day. I may have to reapply each calendar year. I think United has had this program for some time. I did the same program upgrade with United a few years back when NW was on strike.
