1. Limit for changing hub. There are in public world some big airlines that are moving from airport to airport only for reason to kill competitors in ranking routes. In W1609 RCAF changed hubs about 20 times.
2. Ignore list at aircraft and leasing market, that will not allow specific airlines to buy or lease planes In real life you will not sell planes to your competitor. And for brokers will that allow to redistribute planes to more airlines, beacuse big airlines have tendcy to take all planes from market even they are not using them.
