I'm overwhelmed by the amount of info regarding FF programs , so I've decided to just ask and hope to get pointed in the right direction.

My goal is simple: I take an annual return trip from New York to Sydney, and am looking for the best FF program to bank my miles in so I can get the best deal I can for this route. This also involves signing up for credit card offers and other means of collecting miles (shopping, whatever), but I need to know which program to join first . I'm currently with QFF but I live in New York so I can't really build up my miles when not flying.

(1) What is most important to you in a FFP?
Good award redemption rate for my specific route, and travel upgrades if possible

(2) How many miles do you usually fly each year & in what class? How many flights/sectors?
<25000, 2 flights (there and back)

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

(4) Can you choose your airlines and/or class of service? Do you travel for work and/or pleasure?
Travel for pleasure. I've only been flying Qantas but may consider changing if there are cheaper options (but Qantas seems to offer the cheapest price for my route)

(5) Which routes do you fly most often?
New York to Sydney and back

(6) What is your home airport?
JFK

(7) Do you have FFP status of any kind in OW or other airline? What is it? Do you have any miles banked in a FFP?
QFF Bronze, currently just shy of 40k miles

(8) Preferred Airlines? Most common Airlines flown on?
Qantas
