The 175 at all major airlines are deployed on routes that could be served by mainline aircraft. The point of the RJ is to serve out stations that are too small for a large jet. But let’s be real the 175 and CRJ900 ARE large jets. Theoretically let’s say United has expanded to the limit and they are looking for new ways to expend then tapping into those very small underdeveloped markets where the -200 has pulled out of technically can add customers to the system. It’s just does the revenue make up for the costs. There is no longer a regional airliner. E175 are mainline jet size airplanes. It’s just that majors no longer operate DC9s/737-200s/etc. Delta is the only exception with the 717 and now the A220. The regional made sense when they flew B1900 or metro or E120. Now they are just being used because they are “cheaper” which I’m not even sure they are anymore.
