First thing would be ditch almost all of the routes you have. You are spreading yourself way too thin. It is far better to operate fewer destinations with each having at least a daily flight then operating 20 routes with only a weekly flight as you are now.
That way yo will build route image much more quickly and your staffing and marketing costs will be minimised.
As you are now in the red, you're unable to reconfigure your schedule/buy slots so is suggest a restart.
