I'm considering 'chasing' after lifetime Star Alliance Gold status and two contenders for me are OZ and LH. I've a reasonable amount of miles in LH and from what I gather, I need to be 60 years old, earn 1 million miles and LH lifetime is discretionary. However, I am almost 20 years from 60. I like LH because of its generous miles mutiplier for premium cabins. OZ, on the other hand, has a lower threshold for lifetime status but it's COS sucks. Only a paltry 25% extra for J cabin. I would like to get your viewpoints about which I should go for. Looking for the future, I am unsure of my travel plans but then again, all my flights are self funded. OZ will allow me an earlier qualification for lifetime gold but COS earning sucks which mean I may not be able to redeem for flights as much as I could if I had stayed with LH. Hmmm, what should I do?
