Hi, I'm new to AE so maybe this is a dumb question.
Let's say I have one 767-200ER. I'm based in IST so we can consider a short-haul flight to RUH and a long-haul flight to LAX. If we use all the plane's hours on the IST-RUH flight, the plane makes $370k profit per day. If we do it on the IST-LAX flight, it makes only $260k daily. What is the reason to even have long-haul service if a WB plane makes you more money on short-haul routes?
