I'm biking to the Zürich airport tomorrow on a national cycle route. According to Komoot there is a cycle path leading to the airport entrance. When I get there i'm going to purchase a bicycle box and pack my bike.
I tried to do this on a local airport and I didn't find any place to park my bike despite the big parking lot, then I locked it in a random light post and kept praying the whole time so it would be there when I come back
