The (new and old) Austrian CLA gives Dash 8 pilots a 50% share of all new jet positions after five years on the Dash. While the Dash is not glamorous and many airlines favour jet experience, you'll learn a lot of hand flying and technique on the Dash that an Airbus won't teach you. Those pilots moving up from the Dash 8 now tell that they initially considered their Dash posting disappointing (with their flying school peers going straight to the Airbus) but now wouldn't trade their Dash experiences. Once you're on an Airbus you won't get to places like Lugano or Bolzano at all and even Innsbruck is not that common....
As everything, this is a snapshot it is hard to forecast, especially about the future
P.S.: Don't fret about flying a "lame" turboprop. The Q400 is quite hot and a jet departing after one will need some time to catch up.
