Whatever the internal gripes at Flybe and despite the current shortage of very experienced pilots for this sector of the industry, there are, and always will be, many slightly less experienced pilots who are prepared to leave other operators (such as Eastern) to join the Flybe turbo fleet and bide their time until a jet postion becomes available.
I'm not a pilot nor do I work for Flybe, but I've been in the aviation industry for a very long time, and I know that this situation will prevail ad infunitum.
Flying Fiona is either very brave or very silly, with such outspoken attitudes, it's relatively easy for management to find out who you really are, and although they won't worry too much about your opinion they will bear it mind when an opportunity for promotion comes along - unless you've already left to become chief piot at B.A.
