Mass tourism began in the 1970s. Airliners needed something that could carry 350 tourists to Spain or Hawaii cheaply.

A supersonic transport can carry twice as many passengers per day as a subsonic widebody.

How does cost per passenger-km compare?

[rbanffy]

Ticket should cost anything between 2 to 4 times a normal one. If it works, it’ll capture a lot of business and first class tickets from normal airliners

I meant cost to the operator... ;)

My guess is that it'd be twice as much. It uses about 3 times more fuel than a modern widebody, but flies about 3 times faster than them too, so they'd be able to fly at least twice as frequently. All things considered, I'd expect ticket prices at twice the price of coach, perhaps less, but the added convenience of extra departure times and shorter flights would enable a lot of elasticity.
