What I do like about this offer is that the booking and travel period are the same, so there's not the same pressure to plan way ahead and book right now that you got with the previous double status credit offers.
Having said that, the bonus earning potential on this is much lower than in the past, so I don't like that. I'll be curious to see how (or if) QFF responds to this. Overall though, I'd say it's not a good sign for the future of double status credit offers. That particular type of promo may have run its course...
