I think there are two kinds of people: Those who fly often and those who fly a few times a year. Regular flyers know their airports, the days and vacation times. Then you can reduce to 30 minutes airport time. If you only fly a few times a year or don't know the airport well and are traveling during the vacation season, you have to play it safe. Then 1 hour of flight time can quickly add up to 4-6 hours. However, as long as airplane fuel is subsidized, few people will pay twice as much for trains, even if they are just as fast or faster and much more comfortable.
