If true, concord alone would be viable, but a combination of concord and regular planes on the same route would lead to all the business passengers taking concord, and the economy ones left in standard planes, which would no longer be viable.

In that case you could raise the price of Concorde tickets to push surplus business customers back to regular planes. But this raises the question, why would you even want to bother with Concorde in the first place?

It only makes sense if you could attract new business class customers, who would take the faster trip but wouldn't take the slower one at all.

At the same time, when Concorde stopped flying after the accident in 2000, people who used to fly on her, flew on other things, so these passengers weren't lost revenue wise.

Some people didn't fly at all when they would've flown if a Concorde had been available. And those who did fly on other planes paid significantly less.

A significant share of those customers must have been lost by the two companies that flew the Concorde, as the alternatives to it are commoditized and offered by many other companies.
