What does upgrading an airport actually do

pocket-planes

In Pocket Planes on iOS, you have the option of upgrading your airports, but what advantage does that give you, and is there a finite number of times you can upgrade?

It's quite an expensive option, so don't want to waste my coins!

Best Answer

It adds more jobs and layovers. This way an airport is more profitable.

I think you can upgrade three times, but I am not sure about that.
