On the reverse of this, I am oneworld Emerald (BA Gold) and looking to book an Emirates ticket between Singapore and Melbourne. The outbound would be on an Emirates plane, but the return would be on Qantas. Do I have the same oneworld Emerald privileges when I check in to my Qantas operated flight (Emirates ticket) and can I use the Qantas first lounge? I've been scouring website, tried chatting with Emirates but can't get a clear answer. I should add that this Qantas flight from Melbourne is in economy... Any help welcome!!!
