Thanks for the advice so far. I suppose you have to look at it two-fold. On the one hand, at least I could potentially earn some form of status using QF in the long run, but on the downside the majority of the benefits would only be of use if I lived in Australia.

On the other side, BA status would be of more benefit being in the UK, but is unlikely to be earned if I only fly discounted economy.

I'm guessing BA wouldn't match my *A status, but would QF or AA?
