My apoligies I was dislexic. I meant CMH-SLT (Salt Lake City) and then SLT to Mazatlan. Other destinations are SLT to Seattle, DWI-SLT, and I think SLT to LA. The airline will look at the # of people who go from one city to the next through their hub (ATL), say cmh to salt lake, if that number gets over, for example, 500, they start a direct flight with a regional carrier. I believe we will start to see more of this.... thankyou.
First of all, Salt Lake is SLC.
Second, its not 500 people, its more like 70 (or 68 in this case). If they had 500 it would be a mainline 757 aircraft several times a day. See link below.
Third, I would argue that the larger the aircraft the cheaper it is to operate on a seat mile basis. The problem is they can't fill a mainline size aircraft, yet they can a 170. If the larger aircraft is half full than the 170 is the right aircraft for the mission.
Take a look at Deltas schedules. 9 flights a day from ATL-BHM. All but one is mainline. Total distance is 133 miles. Because the demand is there they fill larger aircraft because it cheaper to operate per seat mile.
However, looking at CVG-BHM it all CRJ's. To keep enough frequency for the paying passenger and fill the aircraft to acceptable levels, the aircraft is right-sized to the market. A mainline aircraft on this route wouldn't be full and would be less profitable. It's all economics.
I copied this post from the CHQ Lounge website:

Check out page 6, "10 largest markets without non-stop service". SLC is #6. You automatically have 68 people a day who O&D between CMH-SLC. Just right for a 70 seat aircraft. Now add 2 additional flights per day for a total of 3 RT per day from CMH and how many of those other passengers on that list will now go through SLC to connect to LAX (12 flights/day from SLC), SAN (7 flights), SEA (10 flights), SFO (7 flights) and PDX (6 flights)?
You now have a possible 567 connecting passengers to those destinations without going through more indirect or congested hubs or ORD, DFW, CVG, DTW, ATL, etc.. Not to mention the relief you are giving the ATL and CVG Delta hubs where those flights that are very often full or oversold.
