How do you know if he will be off every weekend?
The rest I agree with. Little to no chance unfortunately. There are no decent contracts, flexi rubbish if you are lucky and you are just a whore to the industry then. Too old for Ryanair so its a turboprop with no chance to jet progression in todays market. If you do manage it you will be extremely fortunate and will be paid a paltry salary until you retire. Integrated will increase your chance by a small factor (hate to say it but true). Old FO's tend to get the hump sitting in the right seat for the rest of their careers. Buy a fast car instead.
