Don't blame AA. You should've booked Y basic or cargo hold for them.

BTW: That's another reason why you don't see widebodies on domestic routes. (At least in C/F) they are configured to be comfortable on >12H rides. Sending lie flats on 1,700 mi long routes is simply overkill. Airlines prefer to sell 3 recliners instead of 1 or 2 beds.
