Captain or FO? I would say you could compare the salary to a regional airline possibly slightly better.
The rest depends on who you work for, leave can be standard 4 weeks sort of thing to 0, availability is usually 24/7 unless you are working for a large department with spare crews.
It really is that variable I'm affraid.
You just need to argue your case in the interview and ask for what you want, no point taking a job and not bieng happy with the T&C
