Also, there's a huge difference between trading off high-value time for middling-value-time, versus actually spending the time. If I'm using my time on the plane to read or catch up on sleep or prepare for my presentation, it is less important to me that my flight be over quickly.
I would pay more and tolerate slower flying times if the trade off was a less hellish flying experience. The TSA sucks. Flight attendants suck and the seats suck. Airport public transportation is usually lousy.
In fact I often tolerate substantially longer travel times to ride on Amtrak rather than deal with the nightmare that is modern air travel.
