For bizjets, that's another good use case, thanks. I don't know how much travel there is along these routes, but you could probably shrink Dubai-Mumbai, say, from 3 hours to 1 hour, and that would be handy for meetings- only a 1.5 hour time difference with IST. But regular subsonic flights can also give you meetings in a day over that, so I'm not sure how much extra companies would be willing to pay for a commercial flight along those routes.
