Still there are not much other routes you can go supersonic in one flight but trans-atlantic, which Concorde could do.
Trans-Pacific which could have been the big money making route, like LAX to Tokyo, you need to be able to do 4737 nm... which makes the 4250 nm just short to make it.
They would face the same problem the Boeing 2707 team had (or even Lockheed with the L-2000 project), no matter how they tried, too short range for trans-pacific in one Hop. So they would have had to make a stop to Hawaï, but then what's the point if you can take first class in a B777 and make the journey shorter in one subsonic flight.
All other routes would be over land, and there again you can't go supersonic (for time being).
In part that will depend upon its ETOPS capabilities, i.e. how far it can be trusted to fly after an engine fails. The Great Circle mapper is fun for playing "what if" games with potential routes: e.g. here's the direct Seattle-Tokyo routing with dark shading showing parts where flying for 60 mins at 410 knots wouldn't reach an airport. So if that was the ETOPS performance for a Boom aircraft (and I've no idea; I just picked a B777 as an example) then the route would have pass a little closer to Alaska and Sakhalin to keep the possibility of a safe diversion at all times, and that in turn might make the route too long.
