As a new airline, I would agree with Jan and advise you to drop routes that aren’t working. Concentrate on a few ‘milk’ routes where you can increase your balance fairly quickly. From a point where you havearound 50-60 aircraft in the fleet, then you can ‘make your own routes’. By this, I mean that you can expand to very unpopular destinations and still fill up your planes (a little like what QR do in the Middle East, and to an extent what GF do). I usually add a few destinations to the east of my hub, followed by a few on the west, and so on. This ensures I have a decent amount of transfer traffic too.
If you want to go the extra mile, log on to another server (you don’t have to use your credits as you’re not creating an enterprise), find a large airline based at your hub, and look at their schedule. if they have 30-40 daily flights to a particular destination, than that is good enough information that starting the same route may well be a profitable decision.
Best,
