Zurich International (ZRH), Switzerland
To be clear, Zurich International isn’t nearly as bad as the other airports on this list. It’s comfortable, has a great collection of shops, plenty of restaurants, and if of course run with Swiss efficiency.
Why then, is it on our list? Let’s just say I hope you never have a customer service issue at ZRH. The staff here have a terrible attitude, security is tight to the point of annoyance, and it generally just takes forever to get issues resolved. Well, at least it’s not LAX.
