RAH flies the 170/175. Compass will be flying the 175. US Airways flies the E190, as does Jetblue.
Given the size, weight, range, capability and capacity of any of that whole family of airplanes, they are not regional jets. If you folks believe that they are, management is going to continue to pay you like regional pilots and treat you like regional pilots when you will be directly replacing retiring DC-9s and 737s...along with the pilots flying those narrowbodies.
How are they different than the CR7/9? Even though the E-jets are larger, weigh more, have engines under the wings and can seat more, they're basically the same thing - small jets with small pay that happen to have 70-86 seats that are replacing narrowbody mainline aircraft and therefore mainline jobs.
