As an American I think they’re tacky too. That style of architecture for an airport doesn’t make sense really. Well. I bet it could be pulled off. But the “architects” designing the airports are the same people designing Greco-Roman architecture on disfigured American McMansions.
Art Decó, on the other hand, would look pretty Americana and elegant for your buildings. It's basically the classical American city depiction for Europeans (noir movies, Superman, old comic strips from newspapers...)
