I agree it is a fixed cost, but the initial cost is expensive by itself before we consider the cost for maintenance. Also 5x for economy is really expensive, I highly doubt that many customers would want this 380 experience for 5x of econ. Airbus 380 is ideal for long distance, then 5*800 from NY to Asia would be too damn expensive: then why not first-class on non-380?
