"People scheduling their travel around limited flights" drove extra operational complexity and expenditure for Concorde; it's not a hassle-free business case.
BA and Air France understood that people paid extra to be able to quickly travel transatlantic[0].
That premium value proposition depends heavily on passengers' expectation that the flight WILL go at the scheduled time. The airlines had to invest significant extra resources in spare parts, additional staffing, and standby airframes to ensure on-time performance.
If the Concorde were to ever develop a reputation for six-hour departure delays or days of cancellations in a row, no one among their premium customer base would bother paying extra for it.
British Airways and Air France did profit from them prior to the 9/11 hijackings and the flight 4590 crash, so it's not an impossible hurdle to clear for Boom. But the value proposition for a new SST is going to be vulnerable to operational concerns that don't affect the rest of an airline's fleet.

These people haven't got a clue what they paid for their Concorde flight today. They just tell their secretary, 'book me on tomorrow's Concorde, I need to get to New York in a hurry!'"
