Flybe solidly profitable? I don't believe that is what they told the city on the back of their last trading statement. Lucky to break even this year would be far more accurate. They still have massive financial problems thanks to a disastrous fuel price hedging policy and the millstone of EMbraer orders they cannot get off the books quickly enough. There is no talk at all (except amongst over imaginative crews) about becoming an all E-jet operator. It's far too expensive to operate on regional routes and despite being a lovely aircraft, the management know that the company badly need the turboprop fleet to stand any chance of making money.
Unless you really enjoy the idea if being made redundant at the start if your career, with a mountain of debt and a type rating that will shut more doors than it opens, you might want to look elsewhere.
It's true, the company can be fun to work for, the flying is quite good, the Dash a good type to turn you into a smart operator, and in the past, time to command in potentially 3 years. But things have changed in the last 2 years, and Flybe would be a very strange choice to make if other options are available.
