Surely nobody keeps records of all the different types they've flown in as pax?
As a tyke I used to, and wish now that I had kept up the practice. Once had a passenger pass a notebook to the cockpit with the request to fill it out, a logbook for all intense purposes. It was interesting to leaf through it and find some long previously known identities and what they were now doing eg ex instructor I had who was 20 YO at the time I knew him now left seat in a 744.
