Star Alliance is offering to comp ex-Ansett frequent flyers with equivalent status on )_any_ * airline if you fly with * ex-Australia before September 30. I was Ansett Diamond (top tier) - I don't actually know if that means I'll get comped to the top-crazy-super-mega-wow!-elite tier, but at least I should get my * gold back.

So with all that in mind, which program should I apply for (all are participating except ANA and BMI)? I tend to fly quite a bit long haul rather than a whole lot of short haul. Which has the best perks?

Opinions/thoughts/comments are appreciated.
