You forget that 15 seats sold on the 70-seater is the same as the 50-seater (minus first class of-course). The 70-seater costs more per hour, gas and cost of the plane (its newer and bigger)
Are you sure about those numbers? When you look at it on a CASM basis, does it ALWAYS work out to be 55 seats? Are you talking SKW's, PNCL's, MESA's, PSA's, ASA's, COMAIR's, Gojets's, or RAH's CASM?
