AA - Thanks for detailing the situation, which is surprising. When the Company phased out the F27 and moved everyone across to the DHC8, there was no re-bonding.
When the CRJ was introduced, I myself was twice offered the opportunity to move onto it, but various factors, mainly the fact that I suspected it would not last very long in the fleet, led me to turn it down. I was concerned that it was too risky a move to make, and although I've sacrificed a couple of years jet salary, I'm happy that I did not take that risk. It would appear that the guys & gals that did are obviously paying for it now.
