I'm a big train fan and do impractical train rides quite often. I dont think millions of people share our appreciation of trains. Most people use whatever is faster, or cheaper. Trains over 3 hours tend to be neither. Paris to Flensburg is both slow and expensive. By most people's standards, the 6h additional duration of the trip offsets the airport annoyance by far.
