OK I just found out how to tell the booking class... it's in the html page on Qantas's website. Mine is 'O' and apparently it earns very little on either BA or AA FFP... I'm hesitating to join QF's because I hope to accumulate miles and spend them easily and quickly. I heard QF has a poor earn-to-burn rate...

Which oneworld FFP should I join and deposit my miles for this class? I have never flown on oneworld before... except for Japan Airlines but that from an Emirates Skywards redemption.
