Unfortunately, Giessen doesn't have an own airport anymore as it was closed after WWII. Therefore the nearest airport is the Frankfurt/Main Airport. It's about 70km away and approached by most important airlines. If you fly with Ryanair for example, your destination airport will be Frankfurt/Hahn. It's 150km away but has a good connection to the Frankfurt city center from where you can go by train, bus or taxi. It's only approached by Ryanair, Sunexpress and Wizzair.
