Hi I am a newbie. Gold QFF, Gold Velocity and just signed-up to AAdvantage. I like AA for their generous rewards flights, and buying miles is such a great deal. I am travelling to USA this week and will be taking domestic flights with AA. I can only book through QANTAS as a reward booking. If I book with AA I can pay cash but can obviously can only list one flyer programme with the ticket. So I either put my QFF number and receive the benefits of gold/sapphire OW, or I do AA and and start afresh. Can I flash my QANTAS gold at the lounge and get in on an AA ticket? What's the best way to change my allegiance to AA? Use gold Velocity to ask for a challenge and collect points on AA and QF? I heard they don't challenge other OW. How hard is it to attain gold through AA as opposed to QF? Thoughts appreciated
