Thanks all, as ever very helpful info!
Slight change of plan, I am now going to sydney, looking to book one way first class on Qantas (but operated by emirates), CHC-SYD
My understanding is that I get the qantas earn rate if its a Qantas flight number (QF8765), so according to their calculator 120 status points one way, no difference between first saver and first flex, is that right?
Thanks
