At one time in the 1990's CO had hourly mainline flights between CLE and MDW. They went from RJ's to Q400's and alot of people are not happy. Why not at least a few 737's on this route. UA back in the 1980's operated 747's and DC-10's on this route. Airlines used to brag about being all jet and that was alomst 30 years ago so they bring this Colgan junk here.
