As all the replies seem to be from 73 pilots, I'll stick my oar in from the 75/76 point of view.
Rostering is totally chaotic and relies on panic management, imaginative manipulation of CAP 371 and minimum 8 days off in 28 (even in winter, when crews are on standby for non-existent flights). Contract pilots were brought in for the summer and due to issues with airside ID's hardly ever flew. Rest days are looked at as indefinite standbys. Expect crewing to call you in the middle of the night if you leave your phone on.
Salary is distictly average.The flying is OK and the majority of the crews easy to get on with. A number of F/O's have been promoted in the last year. Training is OK but expect to do your ground subjects twice as they'll lose all the paperwork the first time.
In summary, if you want hours, a reasonable chance of promotion and a mix of long and short haul, and don't mind your life taking second place, it's great.
