> quite a bit more money

You can get a taste of this when you look at the cost of long distance rail— for example, a trip like The Canadian (four days in total), which VIA understandably sells as a cruise ship type experience rather than practical travel:

Obviously some of the cost difference is just the massive economy of scale enjoyed by airlines, but at the end of the day there are certain fixed costs associated with being in their care for such a long period of time. Even with a cheap ticket where you don't get a sleeper bed and have to buy/pack your own food, they still have to staff the train that whole time.

The last time I needed to go to Chicago (from Boston), just for kicks I looked at taking a sleeper train. There was really no way I could justify either the time or the money for a business trip.

I did take the overnight from London to Edinburgh a year or two ago. It was actually pretty convenient but it still almost certainly cost more than flying.
