I guess the main challenge for all of us is time. Alternatives to flying simply take longer in many cases. I live in Sweden, a country with an excellent train network and with great connections to other European countries. Still taking the train from my home, Lund, to Berlin takes me about 8 hours. A flight from nearby Copenhagen Airport takes 45 minutes. But that is just half the story. I have to work with an administration and a travel system which is entirely catered towards flying. At my university’s travel agency I often have to explicitly demand alternatives to flying, even if cheap and convenient alternatives are available. One example is the trip to Oslo. There is a direct bus from Lund to Oslo which takes about 8 hours but the default option is the airplane.
I appreciate long train rides because they give me a feeling for the distance I cover on a trip. It is also often a way to travel with way fewer interruptions compared to flying where one has to go through numerous security checks and whatnot before boarding the plane. To my that is significantly less stressful.
