What’s odd too is it doesn’t show the exit row for the door aft of the wing. Unless the aircraft is so low in capacity that they have it deactivated like the aft mid cabin “hat rack door” (that’s a really old term, sorry) on the 737-900. I’ve only flown the 321neo with Frontier and been inside Spirit’s but I know AA has the mid cabin lav back there and extra legroom seats.
