My experience is that if you are travelling in J/F with a Qantas BP - but don't have FF status - you'll get turned away from this line. The AA BP have FIRST typed in bold letters, so if you don't have this or OW Emerald/Sapphire on your BP then you're turned away. It's no point arguing that Seat 3A on your Qantas BP is in First class, it just makes them dig their heels in more.
