It looks very much like the UA config as well, and I looked there a couple of days ago for their active seating discussion. For footwell size, they seemed to like the bulkheads (rows 6 and 1).
Cheers.

I see few similarities except for the 3-3-3 Y configuration. In J, UA has 2-2-2 compared to AA's 1-2-1, plus AA's W is 2-3-2 while UA's Y+ is still 3-3-3.
