NewToMilesPr you should just forget about getting an AA award ticket with QR as QR partner award availability is usually super low.
Qmiles are valid only 3 years. It doesn’t work like with AA miles which life is extended each time you get more miles.
If you have soon to expire Qmiles, the best way to use them is to convert them into AccorHotels points : 4500 Qmiles for 1000 AccorHotels points which represent a value of 20 EUR.
