DirkkDiggler said:That only provides the cost of operating that one aircraft on one leg. It doesn't consider the overhead necessary to run an airline. (Cost of buildings, salaries of executives, marketing, training, etc.) All these costs have to be figured into the equation if you want to know what the break-even point is for an aircraft at a particular airline. The aircraft doesn't fly and the airline doesn't exist without all this background support.
Yes, all very good points. there are many ways to play with CASM numbers, with the RJ (at least the smaller 35 to 50 seaters) it always looks bad.
