The airline industry and the current airline environment at CMH has changed drastically since Mesa's attempt at feeder service from CMH. America West was still a fledgling airline at Columbus and was in the midst of Chapter 11 reorganization during the time the Beech 1900's were around. Also connecting opportunities were very limited (and for the most part, still are today.)
And also, once that feeder traffic was gone, the 737-300's going to places on the East Coast from Columbus flew empty, hence the introduction of regional jets to almost all destinations East of the Mississippi.
In my opinion, feeder service was begun too soon and too quickly, but shouldn't be out of the question now. The ERJ-145's could be used to introduce new cities into the America West system as well as provide feed into Columbus, such as Norfolk, Nashville, and Providence. But in order to attract more feed, more West Coast destinations should be added. Seattle and San Francisco could squeek by on O&D traffic from CMH alone, but increased feed could make them even more viable. The CMH-LAX flight is usually 1/3 to 1/2 connecting traffic as it is, so the addition of SEA and SFO from CMH in addition to more feeder cities from CMH could make things much better here. If only I ran America West...
