I'm making CO 100k this year, apparently more or less for practice. As has been noted, an SWU eligible fare is often a $200 or less bump. Again as has been noted, this could be a scam that never pays off, but if there's actually a better chance of securing the upgrade in advance, I'd gladly pay the $200 each time.

I more or less view the "any fare" SWUs as mythical. I don't want to talk my better half into a once a year vacation only to be playing Lotto.

So we'll see.
