I don't know what the take home is on 320, I guess its less as their flight hours vs block hours are very different (you don't get paid per block only flying hour) plus there aren't as many layovers, although that has increased recently. The pay structure here is unfair on all fleets with the 777 being the highest paid to the 320 the lowest.
Staff travel starts after 3 months from DOJ, I think.
