I still haven't received mine since qualifying late March. I sent them a message early Mat and they said international deliveries were delayed but to print card from My Account page. I think they've just forgotten me.
It's not really that relevant. Your new status shows up within q few days of qualification on the Oneworld system so lounge access etc is assured based on that.
I found that the card problem is usually more associated with those who are only QP members and don't have any status on the BP, especially with the BA lounges who get a little cough about presenting the QP card when there is no status on the BP.Thanks for that. I'm just a bit worried as I've heard some problematic things as if you the lack the card the lounge may deny you entry?
