Plan is to get a million people to Mars within a few decades. You can only fly every other year when orbits sync up. Initially, I imagine many Starships will stay on Mars as shelter and raw material. Then there is the idea of using Starships for very fast transport on earth. Fly from NYC to Sydney in half an hour. If that catches on, they may be replacing part of the airplane fleet. Then there is lunar shuttle services, satellite transports and asteroid mining. My guess is: a lot.
