What started out as barnstorming became the world's airline system, thousands of flights a day all over the world. This is how it started. It's small with only a few passengers on a high. Later it could grow into something big.
The difference, though, is where they're going. The airline system carries people between 2 cities. At the end of the flight they have family or friends, business to conduct, maybe an elk hunt. Since there are no places or people in space to visit, there is no real destination. It's up and back, just seeing the sights out of a window. I can't see it growing much beyond a few flights like this one.
