Hi Danou and Berkut
ALL (!) A320 F/O's are A330 qualified and most of them still flying mixed fleet. Only few CMD are not A330 qualified. It's a management decision to keep mixed fleet flying (MFF) A320/A330 AND A330/A340. Where would you put MFF-pilots?
In what I do agree is that benchmarket salary for MD80 and A320 is the same.
