Because our scope limits the number of 70 seat as well as 76 seat RJs. I'm sure the 76 seat configuration works better in the 175 even though the 170 could easily do it as well. Both models could have more seats than our scope allows. I would agree the Compass 175s are not a bad ride In the back. Better than the 757...but then what isn't.

Still we allow way too many large RJs as it is.
