Any idea where the break even cost would be between adding either the max 7 or 319 neo to the fleet versus buying a new type such as the CS series? The larger jets would cost more initially but would also have efficiency savings over time.
Max/neo:
common fleet, fewer crews required, less training cost for pilots, flight attendants, and mechanics, common parts inventory, more seats to allow for growth, etc.

CS or similar:
Clean sheet modern plane, lower purchase price, very efficient, 100-130 seat, would give the company additional large RJ’s according to the current contract, etc

Something like the CS is very efficient but brings added cost. Adding an additional fleet type requires more pilots than adding the same number of planes to an existing fleet type, more training for all employees, parts inventory, etc. Both the Max 7 and 319 neo are band-aid solutions to older models. I really don’t care what we want to fly or what may be better for seniority and career progression. That doesn’t matter since we are all just cogs on the wheel from a business prospective. This is a math question regarding where the breakeven point may be.
