"Sorry, but before this becomes an accepted "fact", what evidence is there for this apart from "heard a rumour from a BE pilot"?
Yes, I appreciate that doesn't quite fit "reliable source" requirements, but it isn't the first time I have heard this (and not from a BE pilot either). As I say, I doubt the Dash 8 is the right aircraft for them, but I am pretty sure that they are looking at smaller aircraft than the 320 (or 319).
I don't expect much more to happen on this until CM takes the reins.
