7000 hour co-pilots get US$145 per day on site, nothing when off.
I flew in Doha in the mid 70s and other than the poor management, it was an easy place to live and obviously facilities must be better by now. Incidently both the manager and chief pilot were 'removed' just after I left. I believe there has been a recent change in management which will probably need time to see what difference it will make.
