First, brilliant marketing idea by UA. This is like the top 20k fliers promo by AA, but with a much bigger prize (and smaller winner's pool) at the end!!

An open-ended auction where uncertainty will just make the bidding (flight miles) go higher. I wonder what they do if you transition status from 2P --> 1P --> 1K during this contest period? I guess it'll have to be your starting status as of 12/15.

Golden opportunity for 2P's to make that SIN run pay!!!!

BTW, I think the highlights isn't the tickets, guys. It's the guaranteed hotel rooms plus Olympic tickets.
