The CRJ7 is almost the same as an CRJ2/ERJ as far as cost. The 900/175s are probably a little more efficient. However, most airlines have scope that limits the number of 50+ seats. There will always be more 50 seaters. They're nice and shiny but every CRJ900/E175 you see out there is a reminder that our perspective for a nice career at the majors will take that much longer to achieve.
