I'm looking at an AA partner award from MEL-HKG. I have a choice of QF First Class for 45k miles (on a 744) or CX Business Class for 35k miles (on an A330). Which would you pick? I'm leaning towards the CX J for the return because a) I've never flown CX in a premium cabin before, b) I will get to fly in QF F on my outbound flight and c) it's 10k fewer miles. But I wanted to check and see if anyone thought the QF F service would be such a drastic improvement over CX J that I should choose it for the return, too.
