The earn/burn ratio isn't as generous as other FFP's, however that needs to be balanced against the much easier redemption. Anecdotally, there appears to be a larger number of *G and Koru members using lounges perhaps due to much easier status earning and payment options for the Koru Club. What was once a relatively quiet lounge (although WLG is like a theme park at 5pm) is now extremely noisy and busy. From a shareholder perspective this is all adding significantly to the bottom line.
Oh the cognitive dissonance hurts!
