You play as the owner of an indie airline company, slowly building your empire by choosing bitizen(s) or cargo to transport in between different airports located in real world cities. Played this one a ton as a kid, I loved choosing flight paths to maximize profit from my armada or watching my planes, and the fact that flights took an approximation of the time they would take in real life was kinda genius (although progress is entirely too slow, as you were forever locked out of any kind of high-level planes if you weren't willing to spend real cash on 'em).
