Those numbers are absolutely ridiculous. They are not in any way close to the actual CASM numbers. Individual aircraft CASM numbers are very closely held numbers in a company. A company like Skywest pays for some of the costs of its aircraft and some other costs are pass through costs that go to Delta or United. Please list your source and if it is some internet web site then I will give a preemptive YGTBSM.

Seriously, if you ask any airline analyst and suggest that a CRJ-900 has a lower CASM than a 737-800 then they will laugh in your face. List your source.
