No such thing as a typical take home pay for SCCM's I'm afraid. Depends on how busy you are, if you are on routes with a good commission (Taba) or night stopping.
Main crew tend to put in more hours than us, although we are running around like headless chickens in the summer, especially when minimum crew on the 737.
I enjoy it. Crews are generally great. I have done shorthaul, longhaul, scheduled & charter, and Astraeus is a joyful bunch of everything with a few surprises for good measure. Admitedly I am at LGW, I don't know where you would be looking to being based.
The grass is always greener on the otherside!
