Ok,
BAladdy , a lot of what you ask is commercially sensitive hence you will get no clear reply from within AEU. The reason we do not repaint aircraft is that we are now in the ACMI market hence there is no point putting AEU colours on them, when the customer may want a variation.
As for the A330 I have no information at all.As for the A320 it is operated primarily as 'ad hoc' charter , hence it can go any place at any time for anyone. I imagine there is alot of 'standby' on that fleet.
