Flew on several AF 744 flights from North America to CDG and an AF 743 from Orly to Reunion Island of all places. Paid to be a pax on AC, TW, Pan Am, RAM(747SP), Aerolineas Argentinas, CP, JAL, and KLM.
Did do one
JS landing into Tampa on a 742 a long time ago. Entered the FD below 10K. 25 some years later, I got the type endorsement and 2000 hours flight time on the queen.
It is all downhill from there I think.
