Gentlemen, thanks for the explantation.
I did not want to nag, I was not aware of the problem in the background.
I am aware, that not the exact number of passengers, that travel to one destination must also travel back to the origin-destination. I travel myself, so I know this first-hand.
But I hope, that it is understandable, that I was asking (no being aware of...), as this has a strong impact on the economics of my game.
Anyway, I am quite "enchanted" by the sim, as it is now, for me it is amazing, how you keep the dices rolling, Sami. Top Job!!!
