There are a couple routes that I always would take a train on though. Milan to Paris is 100€ on a flight 70€ on a train and takes a similar amount of time considering pre and postflight security
I mean the processing stuff. Like finding your bag and stuff. It's true though in the eu I can usually make it out of an airport 10 minutes within getting to the terminal if I have a carryon and the epassport gates are not broken

Btw there is postflight security in the eu, sometimes. It's very rare though. I had to go thru an ID check once in frankfurt once in lisbon
