Talentz's answer is the best in most situation. However, I took a quick look at your airline and HQ. You've almost filled all the routes you can with the Saabs.
There's a few routes left which I think you can put in 1 or 2 Saabs. Going beyond 10 Saab at your HQ now is very unlikely
If I were you, I would declare BKed and start again at somewhere with more potential. However, if you only want to run a small, peace and quite regional airline, you can try open a second base once you have enough cash in reserve
