Fun take on the ATC type genre but for some reason ATC style games have never really hooked me.

I'd love to see a modern take on Airport Tycoon where you layout runways and terminals etc.

I also fondly remember an airline management simulator while in college. I started playing with IdleFlightManager on iOS but it was just insanely easy so I lost interest quickly. The software I used while in college had you manually set fares and fare pool size in addition to buying aircraft, dealing with maintenance expenses, and choosing routes.
