Best to get the position with flybe first!
Yeah all sounds a bit rich to me considering he/she hasn't even started training yet and he/she is discussing their second job already, especially in the economic situation we are in at the moment.
Assuming you are the golden one and get employed by flybe don't start bitching about the salary already, go with flybe and be bonded or self sponsor a type rating its just robbing peter to pay paul, welcome to the world of aviation.
