I'm not sure where to start...
The main problem ASA has is that there are quite a few senior pilots around. We do have a few people who have been here for more than a decade-they are more expensive than a 3-year upgrade.
If DAL had not turned into such a clown circus , they would realize that senior people are generally more experienced, and that experience has value.
What value does experience have to Delta? Do more experienced pilots fly the airplane smoother? Do more experienced pilots know how to massage the thrust levers to burn less fuel?
In my opinion Delta doesn't care who flys their connection aircraft. You were right on the money when you note that more experienced pilots cost more. I guarantee cost is something Delta thinks about.
The problem with any contract carrier is that their business model depends on the company continually growing. At the regional airline level all costs are more or less the same from company to company. Aircraft leases, fuel, landing fees, etc. are comparable at all regional airlines, but labor costs vary greatly from one company to the next. A company that is growing has a huge advantage over one that is stagnant because there is a constant influx of new hires who, as we all know, don't get paid a whole lot. This means per employee costs are lower at the growing company. On the other hand a shrinking company has a much greater per employee cost because even the junior employees are relatively expensive.
The downside of relying on a growing company for lift are the growing pains that come with a growing airline. Problems with training, scheduling, and aircraft deliveries can lead to canceled flights, which can evaporate any savings from cheap labor very quickly.
Theoretically, the cheapest lift would come from one giant company which grows continuously. The problem with one large company is the large company would gain price advantage from being the only game in town, so while they would be cost effective for a while there is potential to get priced out of the market in the long run.
It should be noted that DAL gives not one rats ass about its pax anymore. They are only concerned about the legal liability from a crash. Since the recent Comair crash proved once again that they are completely insulated from any liability, they are emboldened to take risks with less experienced pilot groups. If that means their pax get on planes at Mesa and PNCL flown by totally immature jerkwads (see PNCL crash for that one,)DAL could not care less, just so they don't have to pay for the lawsuits.
-Ain't the new mgmt just great?
This is just wrong. Delta does not want accidents and they are not insulated from their cost. An accident brings bad publicity and reduced bookings. If it became a pattern, several accidents could drive an airline out of business.
The other point I want to make is that Comair is a wholly owned subsidiary of Delta. Any cost associated with an accident at Comair is felt at Delta. The reality is as long as insurance premiums were paid (they were), Delta and every other airline already absorbed the cost long ago.
