You are all barking up the wrong tree.  The problem is not that the costs are not high enough the problem is that there are simply WAY to many passengers, and they don't seem to be limited by anything what so ever.  The game as it currently stands doesn't seem to limit the number of passengers between routes, which may be a problem of transfers but the system needs to take into account that if there is a direct flight from virtually every A to B there is no reason to fly through C. 

The easiest way to do that from a programming perspective would be to have a hard limit on the number of departures and arrivals in a given airport.  If an airport is full then there can still be transfer flights in and out but only if it connects to an airport that is under the cap. 

Right now the big airlines can place a wide body in any airport worldwide and make a profit because of the transfers their network provides, even though that 1 a week service would equal the total amount of traffic that airport receives a year, and they can do it from every hub they have.  It does not make sense.
