Using a long series of estimations whose details can be found in Rick's article he concludes that the annual operating cost for an airliner is about million (not counting fuel, landing fees, and taxes).

That is, selling price at destination MINUS purchase price at origin must be 0,000 or more.Assumption: starship purchase price will only be about

That is, selling price at destination MINUS purchase price at origin must be $100,000 or more.

Assumption: starship purchase price will only be about $1 million per ton of cargo capacity instead of $2 million, because starships are orbit-to-orbit, need no landing gear, need no wings, can use lighter structure because they accelerate under 1 g, and we will assume they can carry twice as much cargo per deadweight (inert mass) as a cargo jet.

Assumption: cargo starship operating cost is similar to cargo jet.

Therefore the starships will do fewer trips per year than airliners, so the starship passenger ticket price (and cargo waybill) will have to cover a larger share of the starship's yearly expense.

For comparison purposes we need an airliner's average cost of running, but the corporations are remarkably closed-lipped about that.
