Boom is planning to operate at Mach 1.7 (approx. twice that of current aircraft) with a range of about 4250 nautical miles (4900 miles, 7900 km). Over land they're only going to fly at Mach 1.3 to reduce sonic boom effects.

That's not enough range to do London - Sydney, it's not enough to do Los Angeles to Sydney either, or Los Angeles to Tokyo, it's basically a replacement for trans-Atlantic flights only because even US cross-continental Mach 1.3 is only about 50% faster than a 737 (3h vs. 5h)... It's pretty much geared to the prestige market only.

Under an hour to anywhere on the planet, meanwhile, is absolutely someone would be a premium for -- and they'll do it for most/all long haul flights if it was available.
