Noticed these in the seat selection key for the first time:

The exit rows on the map all have the green arrows which makes sense:
It's an A320 so I cannot think where any non-exit row other than row 1 of CE would be considered "extra" in the legroom department and that would be a generous description. Is this key actually just for long haul?
I don't have any scheduled A321 flights at the moment, do they give row 9 a green arrow too?
