I live in Australia and occasionally have to fly to the U.S. for business (the Pacific flight alone is a 15 hour trip one way and an 18 hour trip return). I would lower my consulting fees and channel the money into my airfares if I could get a flight that would do it in half the time. 24+ hours travel time (including connecting flights airports and taxis) is torture. Sadly, I don't think I'll get the opportunity for anything quicker in my lifetime. I predict there will be humans on Mars before a supersonic cross-Pacific passenger aircraft.
