If you go into the Finance page you'll see a lot of monthly costs (Gate rental fees, Maintenace fees and, sometimes, Lease expenses). These are charged on the first of every month. To every airline. That's why our cash diminishes so much when the month changes. It's normal.
What can you do? Well, renting less gates, having less planes, leasing in some... all these thing will lower your monthly costs. They will also lower your income, so maybe it's not a very good idea. Basically, we have to spend money to make money. So... don't worry too much. :wink:
