To add to this I'll tell a little story (one of the only one's I have so far in this industry).

We had a quick turn in PVD from gate 1, or well more like pad 1 since there is no actual gate there. Next to us was a Colgan (I think, it doesn't matter which company actually) S340 in the USAE livery. While we had just shut down and were waiting to deplane our PAX the gate agents had sent out the Saab PAX to board that flight. Since there is no sign pointing to the right airplane about 20 people tried to board our airplane (E-145). When the F/A told them that this was not their airplane and they should go to the Saab their faces turned to "Oh my God, how old is this thing?" Between that look and just the look of utter disappointment it was a fun moment for me!

The point I think I might be trying to get at is that PAX will be scared of a turboprop no matter how new it is!

Story time over!
