From my own experience when I started of in the freight world flying a turboprop my basic was around €2600-€2800 before tax and that is ok for anybody straight out of an integrated course like myself and has a training loan to pay back. After my stint on the turboprop I moved on to bigger and better things that is a nice shiney jet and compared to when I first started as an F/O I am now taking home around £3000/ month.
I have freinds in the passenger world though and seem to earn more money then the freight crews!
