Airports what are they good for (Little Upsilon)

i built a airport corporation and contracted full production to my country and let it run for years. I can't find where to see how many i have or if they do any good or cost money.

You can see the number of defensive and offensive airports you have in stock by clicking Trade -> Products in Stock.

I don't think it's possible to deploy an airport from country stock, that your only options are to keep them in stock or sell them.

Hope that helps until someone can offer more definitive advice.

Uh this game is a bit weird although your county would own many airports they will not be operating. Airports are used by air transport corporations only, if you have 10 air transport corporations you will have 10 operating airports (even if your country owns 100 airports).
