Do we know how much more it's likely to cost? I could easily see people paying 1.5x - 2x.
Anything beyond 2x I imagine would start to price out the average person and anything beyond 5x would probably price out the vast majority of potential customers.
People pay more than that for domestic first class, which doesn’t even have lay-flat seats. $2,500 or even $5k for a New York <> San Francisco 2-hour flight would absolutely sell.
A number of US carriers offer lay-flat seats for at least some of their coast-to-coast domestic flights. UA has over a half dozen Dreamliners flying back and forth daily, all with Polaris cabins. I know AA and Delta have routes with them, too. I agree, a two-hour flight time would be better!
Their business model for a long time has theorized that they can deliver an operating cost that would allow airlines to offer tickets at roughly current business class ticket costs, which would be a fraction of Concorde ticket prices expressed in current dollars.
I don't know if those theorized efficiencies will be delivered (a lot depends on that engine) or if airlines will price tickets at that level. But it's the theory so far.
