Errrr, sorry man... your perspective is still jacked. CRJ700's are nothing like mainline. Distance of route flown should not ever fit into the equation of what is "like mainline". Since Delta fly's a 737 and MD80 from ATL-BNA, and Comair also fly's the same route with a CRJ-100 does that make the CRJ similar to mainline?!? My thoughts exactly.
