Leg, in my career at Flybe I have flown with the DFO several times. He is a very nice guy but Im quite sure he will not divulge the company plans including proposed fleet purchases to his pilots. I'm sure he will hold that card much closer to his chest.
So to answer your question. Your mates girl friend's brother who heard it from the DFO's own mouth does not satisfy me we are getting ex EZY 319's.
Anything is possible though!
