I don't know though, it may be worth buying the game just to laugh at the tutorial. I sure had a few laughs. Keep your receipt for good measure. Once we started a new game you select your location from areas all over the globe. You then select a designated set of land in that city to start your airport.
Cost depends upon the proximity to the city, but the city brings people and money.
After getting your area laid out, then you begin your building. You can pick pre-fab terminals or build a terminal from scratch. You then build runways, control towers, parking lots, roads, cargo and maintenance facilities, and airplane parking. Once you get your airport in place, you open up the runways and start business. While your airport is running, you approve contracts from airlines that want to use your airport for landing and loading.
