I usually fly Star Alliance (Gold with UA for 2014/2015) but my client is flying me Qantas to Australia in Premium Economy and I'm wondering to which FFP I should accrue my miles. Depending on the job I might be going to Australia again.

My home airport is TYO (HND/NRT).

My Qantas Frequent Flyer account is still there but no miles.

My JAL Mileage Bank account has 9,000 stray miles.

My AA account had not been used for the past 10 years!

I believe that with JAL and AA, the yearly countdown for elite status ends on Dec. 31 whereas with Qantas it's a rolling 12 months period. Am I correct?

I am not very likely to fly One World next year but who knows... I want to maximise my chances in case I'm due to fly a OW carrier again.

Thanks in advance for your input.
