Look at just the Eagle scales. We pay quite a bit more for 50 seat T-jet than 66-seat T-prop. Its not as extreme on the captain side but there is still a difference as you go up in seniority. All this yet there's no argument that the ATRs and Saabs are more difficult airplanes than the EMJ or CRJ. Yet another reason people flock back to the continent from PR when their seat locks are up.
