Flights with no passengers or profit.

[Anzatax]

Here may be the problem: your airline reputation does not encourage passengers (you start with only 10%), so they are reluctant to fly your airline. Next is the competition - they may have lower pricing and most probably more flights and higher reputation, which draws the passengers their way. So the result is that your poor airline cannot sell any tickets at all.

To remedy this problem, I would suggest lowering your prices and try to fly more and increase reputation. The passengers will slowly start to increase as your airline improves.

Hope this helps. Good luck, happy flying, and welcome to Airline Enterprise!
