I've a friend working for BrusselsAirlines FO320.
Actual conditions are : Roster 6/3 or 5/3, salary as mentioned above, 42Days off a year, plenty of destinations and night stops, good cockpit environment, TR320 is fully paid by the company.
The weaknesses are the rostering making your social life very difficult, barely 1 weekend off a month and no way to get something your asked. Starting your week with a very early flight and finishing with a very late landing. They really don't care about your biorhythm you can get early than late than early again. It's better to speak Dutch if you want to be integrated in the team on outstation.
