I have found zone baording to be quite efficient and works well. Of course elites should have the option of baording just fater FC. NW often baord exit rows with FC not sure if this to be se they ahve adquate over head space or a sneaky way of boarding the plat elites who take most of those seats.

I think zome baording couls solve the elite rush as well if the prioritize elites into early zones but keep zones a reasonable size
