I guess A320 aircraft are fitted with altimeters which allow a greater range of setting.
Both airlines fly A320/1 on this route . Maybe purchaser to purchaser variation.
Further to that, why would a manufacturer spec an altimeter to such a limited range. It's not like this is a 1 in a thousand year event!
