We have a flight booked to Cuba flying Copa. We are QF frequent flyers, but are looking to joining a Star Alliance program so that we can make use of the Cuba flight miles (i.e. I doubt that we will ever fly Copa again!).
My best guess is to join either the Singapore or Air NZ frequent flyer programs as we are more likely to use one of those flying from Australia. Is this logical or is there some other Star Alliance program that would make more sense?
Air NZ seems to have a longer period before points expiry than Singapore. What other criteria should we choose if choosing between these two?
