I haven't seen this layout in person yet, but I like how AA has the A321 configured. The jump seat is along the wall by the door, so there is a missing aisle seat. This gives the exit row window seat behind it unlimited legroom and the two seats next to the jump seat extra legroom. Probably too much space to offer in today's seat cramming climate. I probably will never be on this aircraft so I guess I won't worry about it.
