Here is my information. I am thinking about Qatar, but maybe Cathay or Malaysia (they are OW now? or soon?) makes sense. But I am open to other ideas also.

(1) What is your home airport?

SIN

(2) How many miles do you usually fly each year & in what class?

always > 50k, often > 100k, paid is mixture of economy and business, for awards, always choose business

(3) What types of fares do you usually buy ?

Economy more often than not, sometimes business.

(4) Can you choose your airlines and/or, class of service?. Do you travel for work and/or pleasure?

Majority for work, can generally choose airline, class of service is usually pre-specified.

(5) Which routes do you fly most often

SIN->north Asia (e.g., China), SIN->Europe (many destinations), SIN->US/Canada (many destinations)

(6) Do you have FFP status of any kind of OW or other airline at present?

No status on OW. Member of AA and BA plans, but with very low level of miles/status.

United 1MM, and about to become 1K (again), but I hate United.

(7) What is most important to you in a FFP?

Lounge access, upgrades, business class redemption.

(8) Preferred Airlines

It doesn't specify OW, so: I like most of the Asian airlines, and the gulf airlines. European airlines are next down, then American airlines (generically, not AA specifically) are the bottom.
