I understand your argument for what defines a regional aircraft, but it absolutely needs to be based on capacity, not range.
See that DC9-10 at the top of the page? Has almost the same capacity as the CRJ-900. 30 years ago that airplane was being flown on the same routes you're flying and those pilots were being paid a higher rate.
I'm not trying to pick a fight with you here, I'm just trying to make my point why I feel it would be wrong to allow range to define what is a regional aircraft.
