Wow thank you so much for this explanation guys!

- I was an Asia Miles/Marco Polo Club silver member, but crushed all my miles on a business class ticket recently. So I want to start a clean sheet with a new FFP.
- I live in Amsterdam, like to earn miles for award travel towards Asia. (but any destination for award travel will do in the end)
- I don't have a specific Alliance I fly with, I rather always choose the cheapest Business class fare available for longhaul travel about 4 times a year.
- My Itinerary as screenshot below
AMS-DFW on IBxxxx / Fare code N (op. by AA)
DFW-RNO on IBxxxx / Fare code N (op by AA)
RNO-DFW on BAxxxx / Fare code O (op by AA)
DFW-AMS on BAxxxx / Fare code O (op by AA)

- As you can see, FI earns the most, but looking at their award chart, they charge insanely amount of miles for award travel?
Any recommendations on which FFP I should start my clean sheet with?
