Not taking away from your point, just for comparison:

A British Airways first class LHR-JFK roundtrip is $10K today for an 8h flight. Supersonic would be 3h.

Is Boom aiming to be faster than the Concorde? I don't think so.

Their website says:

    > Overture will carry 64-80 passengers at Mach 1.7
Concorde flew NYC<->LON in 3.5 hours. I guess Boom will fly the route in about 4 hours. Also, regular commercial flights on NYC<->LON are currently 7 hours.

Also, using Google Flights, I priced LHR<->JFK on first class about T+1month for 7 days (Mon->Mon). It is about 5.3K USD round trip. I am surprised that it is so cheap. I guess that route is very competitive.

I don't understand the excitement on HN about Boom. The market is tiny. This is a terrible investment. What is the global demand for this aeroplane (if they ever build it)? Maybe... max 200. Look at the order book from the 1960s when the Concorde first flew. Less than 100 total orders. Are people forgetting about how incredibly loud is a sonic boom? It is unlikely that it will get rights to fly over land, just like the Concorde. Also, it is terrible for the environment. The Concorde burned fuel (passenger miles per liter) at roughly twice the rate of non-supersonic aeroplanes.

Remember a few years back when the Canadian-made Bombardier C-Series was selling well, so Boeing got their allies in the US government to impose a 300% tax on them as an "America First" policy?

Well, the rules around sonic booms were similar. Were there sonic booms? Sure. But the real reason for the ban was that they were foreign-made sonic booms.

Now the world's only supersonic passenger plane is being made in America, you might find Congress is much less worried about sonic booms.

Is it? I lived in Kansas in the 1960s. Sonic booms from the AF base were common. They weren't that loud. Electric storms (a regular in Kansas) were considerably louder.

5-7 times as much.

My dad said when he pushed his jet supersonic, you could watch the gas gauge unwind.

The one new factor is the route fragmentation that occurred over the Atlantic with the 757 and 767 and the fragmentation that occurred over the Pacific with the 777 and 787. These changed from a model where only hub to hub flights where every seat had to be sold to be viable from a financial point of view to enabling many city pairs to work, and airlines still to make a profit, even if the business class seats are not fully sold. This led to a much larger market, which plenty of room for 3-10k "business class" tickets on these flights.

If boom can hit that same number, they will have success out of the USA <-> Europe market and premium intra-asia flights - the two most profitable route systems in the world.

They claim they have sonic boom solved by modifying the airframe shape. Otherwise, i agree with you. It will be a thing of no real consequence just like the original Concorde.

One of the unique selling points of their proposed aircraft is that it won't be so loud:

> Boom says Overture will be a lot quieter than Concorde and the supersonic military aircraft that were flying at the time the FAA ban

I feel that you're getting diminishing returns at the point of reducing 4 hours to 3h30, given that flight time is just a part of the whole "door to door" time, there are several hours at least that aren't flight time, and that the expensive tickets all come with an hour or three in an airport lounge.

I think the real advantage would be for transpacific flights. San Francisco to Tokyo is currently about 11.5 hours, assuming a similar ratio (maybe slightly better due to flying supersonic for longer), Boom’s time would be around 6.5 to 7 hours. Savings would be more significant for East Coast flights, ATL-HND would go from 14.5 hours to under 8.5.
