What about Flying Blue from Air France and KLM? I think FB is simply THE best for you.
You need 70k/year to become and remain platinum. As a platinum member you receive 100% mileage bonus.
Ten years platinum, lifetime platinum.
Air France is one of the largest carriers in the world and has lots of partners besides ST like JAL.
As a business flyer it will be quite easy for you to get platinum. (*1.5 actual miles)
If you fly 10k on business :
status miles 15k
destination miles 15k+10k = 25k
And it seems you fly often OZ, a member of Star Alliance. Why not claim *A platinum at the same time? It must be very easy for people like you. With FB you only need 70k/year, and it takes ten years anyway. So why not?
BMI, also a member of *A, has one of the greatest FFP in the world called Diamond Club.
First, you need 16k to get silver and then ADDITIONAL 38k is required to get gold which is the highest at BMI.
You need 38k/year to remain gold then.
Ten CONSECUTIVE years gold, lifetime gold.
Gold members get 25% bonus miles which isn't that great but BMI is VERY generous to business and first flyers : *2 and *3 each.
If you fly 10k on business :
status miles 20k
destination miles 20k+2.5k = 22.5k
Be aware AF FB is talking about a calendar year while BMI DC is somewhat complicated. - To your favor.
The timer starts once you enroll. Say 1st November 2006.
You accumulate 16k by 1st February 2007. And your timer and status miles are resest.
You accumulate ADDITIONAL 38k by 1st August. Then you become gold and everything is reset. 1st August is now your date of importance. 38k until 31st July each year.
Don't worry, your destination miles never reset or even expire.
You are already lifetime elite at OneWorld. If you manage your flight plans with some care, In ten years you are lifetime elite at all three Alliances. Congratulations.
The other alternatives are Korean carriers KE and OZ, if your primary interest lies in becoming lifetime platinum ASAP : Million Milers get lifetime platinum.
They both suck regarding bonuses, but they have some finest lounges and services.
And with OZ miles you can do some crazy AROUND trips.
