I fly SF->NYC redeye regularly. The practical side of takeoff and landing is that I get 4 hours of sleep max. I also start to sleep around 2AM NYC time. If I could reduce flight time to 2.5 hours, I would rather land in NYC at 2AM and get to bed there so I can start my day much better rested.

But do you fly in first class? Because for cheaper than Concorde, that's what you could get (and that's what Concorde was competing against) and usually in first, they don't wake you up for breakfast or whatever before you land...

And the other issue in your case is flying supersonic over land but I hear you.

First class is all very well, but you don't escape the unfamiliar bed; the noise of the engines and other passengers; the weird air pressure; the fact you're in your travel clothes; the strangely corporate environment; or the jostling and noise of landing and takeoff.

Of course, some people are less sensitive to these things than others - and jobs with a lot of travel probably select for people who find the experience of flying tolerable.

Yes I do and they absolutely do wake you up before you land. It's an FAA requirement that the seat be upright.

it might be an FAA requirement to be upright, but iirc some other international airlines (eg. virgin atlantic, air new zealand) allow you to keep your biz class seat in seating position during takeoff and landing.

At some point, I decided I'm too old for redeyes unless I really have no choice. Yes, it means getting up early to get in at a reasonable time but at least I sleep in a real bed.

I've flown London to Washington DC for meetings and then immediately returned to the airport to fly back, and I'd have loved to have had the ability to fly supersonic for trips like that.

So while "just" flying East might be less attractive, very brief return flights will be attractive even if one of the legs doesn't seem very beneficial.

There are plenty of scenarios cutting hours off will improve. Whether there are enough of them to make Boom profitable is another matter.
