What is the range?

Saving 3.5 hours between NYC and London is better, but not vastly better than the status quo. Your total door-to-door travel time will still be about 7-8 hours.

But in my office, just about everyone flies transpacific, or else even longer distances to Europe at least once an year. Mostly business class. And for us, halving the time would be a huge win. But for that to work, the planes need to be able to make the distance.

Good question. It's the longest flights that are the most irritating, so the willing to pay may be higher. The example given on the Boom site of Los Angeles -> Sydney becoming 7 hours instead of 15 is compelling.

The reverse is true for me, I'd choose 15 hours in a flat-bed vs 7 hours in an ordinary seat.

There is a point here. I am so used to travelling to and from Australia, that I find flights less than 7 hours to be annoying. You go through all he hassle of getting onto the dang plane, but don't have time to experience your flight in a relaxed, enjoyable way.
