I just received mine after hitting 2000 points (I live in Switzerland so I use the euro-cheat).

The rules say you can use it on redemption booking. So does this mean that I could buy, say, a WT+ ticket, upgrade it to CW using miles, and then upgrade this to First with the GUF2? Reason I ask is, that for someone like me, there isn't really any other ways to get "redemptions" (I can't use the american Amex tricks and so on), yet elsewhere in the rules it says something about miles not being possible... so I'm a little confused

I don't mind getting two CW tickets to a nice far-away place, but if I could get cheaper WT+ and upgrade those with miles and add the GUF2 on top, it would be even better.
