I think the real advantage would be for transpacific flights. San Francisco to Tokyo is currently about 11.5 hours, assuming a similar ratio (maybe slightly better due to flying supersonic for longer), Boom’s time would be around 6.5 to 7 hours. Savings would be more significant for East Coast flights, ATL-HND would go from 14.5 hours to under 8.5.

East Coast US to Japan supersonic? This is the stuff of fantasy. With the insanely high fuel burn and very small aeroplane body size, where are you going to put all the fuel for a trans-Pacific flight? NYC<->LON was already nearly the limit for the Concorde. As I understand, they had high priority when landing due to low fuel.

Interesting, I hadn’t realized the range was so short. I guess if they did trans-Pacific it would mostly be limited to Seattle to Tokyo, or routes with a stopover in Hawaii.
