We have just verified using a different system and the availability shown above is, indeed, accurate, with 7 being the maximum number of available seats that AA is willing to show.
The industry-standard values for the maximum number of seats are 9, 7 and 4 (depending on the carrier/cabin).
really, alright, I know some Overseas carriers show only 4s, but I always thought AA shows 9s.
noted, thanks for the reply
