WR, last time I checked the -100 and -200 Dash8's have 36 seats, so thus still LC RPT, The -300 and -400 would be HC being 50 and 72 seats respectively. So assuming you were given a CMD with <500 multi cmd you would be restricted to the -300 and -400... ignoring any exemptions that they would likely have.
On a different note, anyone know if QFLink Trainees have any command prospects?? Or are they going to be career FO's too??
