Airports work great in real life. But in real life airlines have hubs. If we could have special contracts to hub an airline, for long term. Those couple of game years you can have a nice well paying airport. Players could hub a regional airline, like horizon in real life. Hub a major airline, like Alaskan. Or hub an airline like delta, and get both kinds of gates. This with an addition of check-in desk and gates reserved for certain airlines, would allow for customization, and more flights, consistently coming from a couple airlines, would make the game nicer and more realistic.
I know that the idea of dedicating airlines, to gates has been brought up before, this added with hub bing would be cool. Like I would be able to make a terminal just for a couple of airlines, or hub one airline in a terminal.
This idea would require changes. For every gate, check-in desk, baggage bay, and baggage carousel, players should be able to chose which airlines, can use them. An airline can not have any flights if they do not have each.
For this idea you should probably add:
-I would also like to see boarding desk being able to be shared for small gates only.
-a predestined baggage carousel, which has a slider to change length and width. That looks like those at IRL airports.
-Pre-determined, baggage bays, gates, service vehicles, check-in desk which players can change airlines, using a check box system like that of those for employee lounges.
-hub contracts: giving player some cash to get the terminals and gates ready for them to hub.
-Airport staff with designated airline focuses, which can be set for certain airlines.
-a new flight planner interface. Once played decide what airlines to get a contract with, they will then go and dedicate equipment and employees as they see fit. Once an airline has everything it needs in the aiport. The players click what gate they want.
-gates have been pre-designated, so by clicking on the gate, you
See only the airlines for that gate. Then the interface works like it
does now
-hub connections, that go through the airlines which have a hub contract with you.
- bus stands that will connect passengers between terminals, with an ability to set up routes and dedicate busses to them.
-tunnels of service vehicles to get under runways, so terminals can be not connected to the main part of the airport, and be across a runway from one another.
