I left some time ago because of the length of time away from home, at that time it was only 8 days a month off in UK although I believe it is a bit better now thanks to BALPA. As it is medium haul and many destinations only served 3 times a week then your work is never limited by flying hours as you are spending a lot of time on the ground down route.
I have to say though that BMed is an excellent training airline and that you will find no better grounding in airline flying. i.e. from LHR to some pretty demanding foreign destinations.
Now that the job market is picking up again I would anticipate the turnover there increasing again as evidenced by their recent ad in Flight for FOs and DE commands.
