-'Average' people got to fill the seats not taken by the rich and famous on occasion. (I flew it once - BA 747 LHR-JFK, Concorde JFK-LHR, mid-nineties. The round trip was organized by an aviation magazine, once the ‘wow, I’m on the Concorde’ novelty wore off (a couple of minutes after going supersonic), the experience was rather underwhelming.
Glad to have experienced it, though.
