Why do you assume intercontinental flight will use the same configuration as the orbiter? First of all, the orbiter still needs lots of oxygen on board, even though they can save around half of it with their hybrid jet/rocket engine. Furthermore it needs heavy heatshields. Both things that are not needed (or to a much lesser extent) in an intercontinental craft. The saved weight for oxygen alone should allow you to go from 30 to 200 passengers, giving you another order of magnitude - and suddenly you're at first class ticket prices.

By the end of the process you'll be pining for the days of having to just lug around a little oxygen.
