IIRC the plan was for 100 passengers per launch to Mars. Assuming only Earth based point to point travel this could probably be increased as you're not also running supplies & equipment. But assuming 100 passengers and assuming they get the launch cost down to $5MM (as proposed in the article) that is $5000/seat which is easily comparable to a first class ticket. Further (optimistic) extrapolating with more and more Starships available, the tech becoming cheaper/more reliable as time goes on I could see that price dropping over the decades. Just as air travel changed over the years from being out of most people's reach to being routine I could see something like this supplanting planes for those ultra long haul routes.
