No, they fly 76 seat jets. I too believe they should be mainline airplanes. CR9 and E175 are not regional airplanes, especially given the routes they operate. ATL-COS and ATL-TUS are NOT regional airline routes. Having these aircraft at the regional level hurts us all, as this means fewer job opportunities at the majors.

Mesa flys 80-something seat jets for US. They are high density configured CR9's...yet again, airplanes that I would prefer to see operated at the mainline level.
