I think I have figured this out:
My statement shows that I earned 10,364 Flight Points, of which 7,745 were transferred to ThankYou Points.
My statement shows that I earned 11,324 Additional Bonuses. That number includes those 10,364 Flight Points. The difference is 960 points which is exactly the amount of my Relationship Bonus, mentioned only in a paragraph at the bottom of the statement.
Edited to add: The amount of Bonus Points posted to ThankYou Points is 8,705 which is the sum of the Posted Flight Points and the Relationship Bonus 7,745+960=8,705. The statement will be much easier to understand once all of the legacy Flight Points have posted, but I have flights booked out into July.
Ah, there we go.
I earned 9,124 FP on the statement, and 1,252 Relationship Bonus. I also had $32 in Airline Credit posted, so:
9,124 FP + 1,252 Relationship Bonus + 32 Adjustment for Flight Credit = 10,408 "Additional Bonus"
However, my ACTUAL earning to my TY account was 865 FP + 801 3x + 64 1x + 819 (Relationship Bonus) + 433 (Relationship Bonus) = 2982.
Pretty weird breakdown, but at least the numbers add up (sort of).
