The longer the flight the less money

[Ryanamur]

The reason why your profits seem to evaporate on longer flights is quite simple: there is a ceiling to what passengers are willing to pay.
Once you reach that ceiling, you stop generating income and you just burn fuel.

Let's say that the ceiling is based on 1000 NM (don't ask me, I don't know). As soon as you pass that point, people stop paying for their
tickets. When you think about it, it makes sense.
