Why flying remains out of reach for most people

A commercial flight depends on more than an airplane: passengers need an airport within reach, a route that serves their destination, and enough money and time to make the trip. Those conditions are concentrated in wealthier regions and major cities. For people living far from airports—or where flights are expensive, infrequent, or impractical—air travel may never become part of ordinary life.

That uneven access is easy to miss because airports and airline routes make flying seem ubiquitous to frequent travelers. But the people most visible in those places are a small slice of the world’s population. A full cabin can carry hundreds of passengers while saying little about how many people have ever boarded a plane.

Turbulence is a consequence of being airborne

Turbulence is the irregular movement an aircraft encounters when it passes through shifting air currents. It can feel dramatic in the cabin, but the sensation is a feature of flight, not an experience shared by people who have never flown. The large number of people who have never encountered turbulence on a commercial flight follows from the same basic divide: they have never been on one.

The striking contrast is that a routine moment for a frequent flyer—a seat-belt sign lighting up and the plane jolting briefly—remains entirely hypothetical for most of humanity.
