You will have to factor in the 4x associated costs as well (fuel, maintenance , flight crew, airport costs, etc).

I have 0% knowledge on commercial flight OPEX, but at first glance it doesn't sound as simple.

This probably is true on the air too, granted that you have a similar efficiency and fuel combustion.
