Yes, the benefit of private jets and charters is that you can land just about anywhere, including both large commercial airports and smaller private ones.
People who fly privately tend to prefer landing in private airports, an option that saves time.

There are fewer planes, affordable landing, ramp, and fuel prices, not to mention the time savings from avoiding commercial traffic on runways and long TSA queues.
