Commercial bus one way is roughly $219-231 from Austin, TX to San Francisco.
One way flight thru Orbitz.Com is only $112 for the same trip.
Some things never change. When I was joining the Navy in high school (through the Delayed Entry Program), the cost to fly me the airport closest to my in-processing military base (Fort Douglas) for interviews, physicals, paperwork, etc. was half of what a Greyhound bus trip cost. But their travel office would put up a fuss and fight the flight every time. It’s like they wanted it to cost more. For some perverse bean-counter reason, they probably did.
How much would a nice cruise from San Diego to San Francisco cost? On a container ship, of course.
