If they sold the fleet and got Dash 8's, yes i'd leave. Thats your only answer isn't it, leave? We do retain that right. Its not like there are no jobs out there, what ever your fleet.
As for salary is it really that bad? I dont like the way things change but as for the cash its not so bad.
I am not too sure about this divide between the fleets either, I've never see a widebody crew ignore a a narrow body crew, just doesn't sound true.
EY is not all roses, yes, but is it really that bad?
