I have always wondered why AC/Jazz went with both the E75 and CRA jets for their fleets, considering they are so similar? I mean, they are within 2 seats of each other, with the following major differences:

CRA
-operated by Jazz
-Longer range
-No ovens
-Smaller overheads
-Cramped space in the back of the plane (near the lav, good luck getting by if anyone is waiting!)

In terms of the range/ovens, I don't understand the appeal- it's not as though AC will put a CRA on a flight to it's full 2200 mile range anyways! The longest CRA flight I know of is YYC-IAH, which is the only one I can think of that needs more than the E75's range. The CRAs primarily fly legs such as YYZ-DFW, YVR-YYC, and YYZ-LGA/ORD, all of which would be fine with the E75.

E75
-Shorter Range
-Interior is similar to mainline, takes away from the "Regional jet" look/feel
-Bigger bins

Does anyone know why they operate both? Is it simply that AC wanted one and Jazz wanted the other? Did they plan to launch other longer/thin routes that required the CRA's range (Even if they did, I can't see a 4 hour+ CRA flight sounding popular to PAX)? I appreciate everyone's ideas!
