I've only been playing for a little more then a week, but I have noticed that route demands in game are nowhere near the real world. I am guessing most of players base their airline in home country because they know their geography etc.
I live in Oslo, but since there were two airlines based there already, I based mine in SVG which is a fairly large city in Norway. Routes domestically in Norway are not accurate, because to destinations like OSL, TRD etc, there are several flights an hour operated by SAS and Norwegian Air Shuttle, while in game there is only enough demand for 1 flight, or maybe 2 a day.
Similarly, there is no demand for tourist traffic, where in real life flights to Malaga, Alicante etc are full from Norway. How realistic is the traffic patterns to real life? Or is it just randomly based on size of airport/city.
I would request game developers to gather some statistics from players, or look at real airport time tables to see the demand. I mean if 8 flights are operating form OSL to London each day with Airbus 319 / B737, there must be a little more demand then 300 pax per day...
I would also like to play a game where real life airlines are already operational, with their route maps etc, and we can try to start our own airline to try to establish ourselves, because that would have been challenging to see if you can start an airline in the current world picture..
