I'm based in BNE so there aren't any *A flights with F available. J is available on TG, SQ and NZ. I have read some rave reviews of TG's F class but to do this, we would have to pay for BNE-SYD-BNE and use miles to redeem F plus pay an extra 30k US DM miles per person. Is it worth it? It would actually be nice to have this kind of information on all the *A carriers as well.
