There are plenty airports in Microsoft Flight Simulator. Thanks to our community, more than 700 Intl. Airports are now even more detailed! Any reasonably major airport that regularly operates commercial worldwide flights and has more than one runway is considered to be an international airport. You can pick any airport from this category and add it to your simulator to enhance your experience during flight. While some airports add great visual value, others expand the current airport scenery or fix bugs included in the vanilla game. Have fun!
