Cancellation costs for airline contracts


I have experienced this ‘issue’ twice now where I have build an airport using small stands and a dozen or so airlines and made a few million. With those millions I build an airport with medium stands, cancel the old airline contracts and take on new ones with airlines of my choice. After doing this, I noticed that I went from 3 million in the bank, to negative 8 million due to the cancellation fees. I should note that none of the airlines had planned flights at the moment of cancellation.

Don’t get me wrong, I don’t necessarily object against the cancellation costs, but a message saying “cancelling this master contract will fines you $800,000” would be nice. (Also $800k might be a bit much)

Does anybody know if there are cancellation costs and how the price is calculated?
