Developer’s Description
By LVGameDev
Construct your terminal, hire staff, sign airline contracts, tweak the daily flight schedule, configure standby gate availability, plan & design your infrastructure -- bag handling systems, roads & taxiways, fuel systems, runways, gates, hangars, service vehicles, and everything in between. Deeply simulated gameplay where each detail makes an impact -- down to the trash cans.
