Does anyone know why the profitability changes even when servicing the same airplane model from the same cities? I noticed this when I was servicing a B777 from IAD to my NGO airport. The difference between the two planes was over 500$ even though it was the same plane from the same city.
Is there any formula to this or is profitability completely randomized? I understand the fuel cost varies depending on city and aircraft type, but in this instance they were both the same. The only thing I can think of, is the game randomizes profit to make it more realistic to differing passenger loads, which is fine, I just want to make sure I understand how it works or I am not missing something.
