There is no reason to fly short distance if you want to go from city center to city center. I used to travel quite a bit between two cities where the option was a 3 hour high speed train and a ~45 minute flight. And while the train was great in theory (fast, comfortable, free wifi etc.) it wasn't quite reliable enough. Being 1-2 hours late was common enough that you basically had to take it into consideration when making plans. If it was an important meeting I would normally fly in the morning to increase the chance of being on time, and take the train home in the afternoon when I could just chill with a glass of wine and watch a movie and being an hour+ delayed wasn't a big deal.
