Come on then, but I only can give you an impression from the A300 fleet. We work under ACL but still contracted by EAT Belgium. We work indeed some kind of 7/7, sometimes 8/6. As a Bru based crew member ACL is positioning us to and from Lej on last Off day/first Off day with a rest day somewhere in between(most off the time in Lej in the weekend) so you are not going over the 7 days consecutive duty. If you are lucky everything is within your 7 days duty. The roster is quite stable but we don't fly a lot. We hear already months rumors about more flights for the A300 but there it stops. One Fo who was dismissed last year by EAT is hired back by ACL directly Lej based.
At the moment we still have our Bru base but personally I think it is a matter of time (1 year, 2 years???). Although we know already that every upgrade, type change etc. will be Lej based.
