As it was explained to me by the QF lounge agent, the name on your QF card and in your passport must match, otherwise LA tries to make your QF number a LA number. As such, you need to either see a LA agent at check-in or at the gate to manually override the system and add your QF number to your booking. After doing this on my last trip all LA segments (SYD-AKL-SYD) posted within 4 days of flying. I was especially impressed given that AKL-SYD was manually boarded due to computer errors.
