Nobody in their right minds would want to go from a CRJ to either a 146 or a Q400- the type ratings are virtually worthless in the UK in any case. The thought of having to pay for the privilege is horrifying.
The company needs to realise that it is their indecision, and their appalling planning in the first place, that led to this situation. If they want to retrain pilots, they should do so without bonds.
The only good (?!) part in this is, that should a pilot leave, the company they went to would almost certainly pay considerably more than flybe, making the bond easier to pay... small consolation I guess.
I agree with others, it is about time BALPA justified the large amounts of money we pay them, got of their chuffs and sorted this out!
