I left a brightly coloured LCA and now fly charter 738's. The work is much lower pressure, and we're treated with respect by our colleagues (crewing and ops even call flt crew Sir!). We have some long days (Egypt and back is about 5.5 hours each way), but some shorter ones too, and there isn't the continuous rushing around (plenty of time to stretch your legs and have e brew on a 1hr turn-round).
The only fly in the ointment is being based away from home, but I'm less shagged out and stressed on my days off, so I suppose I'll live longer and enjoy my family more.
Just check the payscales before you decide - you may lose a lot of money if you leave, but it may be worth it.
