Actually from what I hear its better to leave as an f/o. Problem starts that on one hand you get paid more as a captain but its all the strings that get attached and that each year management will give on one hand and take with the other. In the end you will be no better off and more than likely have taken year on year pay cuts in real terms or erosions in T&C's regardless what management say. But you will be on more than an f/o at another airline and that is where the problems start. Leave to take a pay cut or stick it out at FR. Hence why jumping ship is better until at least there is a massive regime change and FR employees are valued and renumerated accordingly.
