The class of "regional" jets is based on prior prop plane design, such as Canadair RJ50/70/90 or Embraer's RJ 135/140/145 series with smaller seats/pitch/overhead bins. The class of "regular" jets would include the Embraer 170/190 series, Boeing's 71/2/3/4/5/6/7/87, DC8/9/10/MD11, Airbus 310/18/19/20/21/30/40/80, L1011, etc., etc., etc.
Like I said: It's a LARGE regional jet. It's "a bit" narrower, AND shorter (both in lenghth and hight off the ground). The Canadair RJs are NOT based on a prior prop pane design. The original CRJ was developed from the CL-601 Challenger business jet. Mesaba and Skyway aren't going to be flying DC-9s or 717s because they aren't regional jets.

The Impacts of Regional Jets on Congestion
What is an RJ?
• Most likely it is operated by a regional airline
• Contains 32-90 seats, the same as medium and large turboprops
I don't understand people's aversion to calling these regional jets.

Is it that you LIKE them and a regional jet would be beneath you, so it CAN'T be a regional jet?

Do you work for EMB? We're not going to see these flying trans-con, Hawai'i, or trans-oceanic. They are actually more than "a bit" smaller than a 737 or a 717. And their range and market are REGIONAL.
