Hello hardcase,
I am not at cityjet but from what a friend told me, it is something around 3500 euros per month for an FO, about 4000 euros for an sFO, bear in mind that basic salary is very low so that's only if you fly as much as you can (max duties because avarage flying hours is about 55/ months)
I am not sure if they have a pension scheme.
If you are sick more than 2 days in the year you won't get any cents from the air france annual bonus.
So compared with your current company, you will work much more and earn less if you go to cityjet
All the best
