This is what I got from Customer Relations today upon asking the question about the 787:
Dear Dr. Zpaul:
Thank you for contacting American Airlines.
Pitch/Bed Length Width Seating details
Business 60-61/77 21-26 28 flat bed seats
Pitch Width Seating details
Main Cabin Extra 36 17-18 57 standard seats
Economy 31 17-18 141 standard seats
I presume that row 8 and exit rows, with trays in the armrests, are 17, and the rest of the rows that allow for a bit of spread can get up to 18, but they sure do play around with not answering with actual numbers you can count on.
