I am looking to get my family of 4 from Singapore or Hong Kong to Sydney in J class. I can achieve it with QFF from Singapore but very attracted to getting us on CX from Hong Kong. Both Qantas and Asia Miles show a max of 2 seats available on flights I am looking at. I am wondering if I could redeem two from each (i.e. Qantas and Asia Miles)?? Or could it be possible they are the one and the same award seats? I can waitlist the other two but I am going to need some certainty. I have points banked with Amex I can send either way.
