Sure, but as is the same at BA. Seniority is everything.
But BA only have 2 bases which makes seniority a lot easier to deal with.
The problem at flybe which PT6 alludes to is the Embraers are currently replacing Dashes, understandably when this happens the in base senior Dash guys move on to the Embraer.
This has led to very junior Dash Captains (in GLA) getting their move to the Embraer and "skipping" company (but not base) seniority.
