A -200 with 40 pax will always cost less than an A320 with 40 pax. It's about net profit, not cost per seat-mile. CASM is one metric, but not the most useful one.

Regionals will ALWAYS have a greater CASM. They have fewer seats. Fact of life. The reason AA makes a killing is because regionals keep up the frequency of feed to/from the hubs and makes CONNECTIONS possible that do not involve 3 to 6 hours of waiting in an airport. Nobody would even book such tickets if they had to wait that long between flights.

Cheaper DOES NOT mean more profitable.

Pointing out higher CASM at the regionals is simply a tool for middle management to try to get everyone at the WOs to be happy with their current wages and not fight for what they deserve.
