I believe that was on British Airways BA and the standby fare was $100 with a SA return on a BA 747.
If you got on going London getting back was not a problem.
Frightening NOISY takeoff; the fuel burn was the same as the 747; carrying 1/3 the passenger load.
Cruise altitude was 12 miles up (55000-60000 feet) speed twice the speed of sound.
While on temporary assignment at JFK saw it many times and wished I was on it - but not to be !
