I am cx gold i.e one world ruby..travelling on qantas issued y ticket on qf2 was refused admittance to emirates lounge in July.Travelled on qf1 4 weeks earlier and was admitted.I asked for supervisor(s) and listened to babble about how I should have flights credited to cx and not qf if I wanted to be admitted. I think under one world rules I should have been admitted as I was on qf1..same ticket, or have there been enhancements I don't know about.
