I flew on Wunala Dreaming from Melbourne to Sydney in 2002 as part one of a connecting international flight to Honolulu - but the onward aircraft was just a plain-jane Qantas 747. Flew back on a 747SP I think. This was pre seatback entertainment, and I recall getting two Woody Allen movies on the way home which annoyed me no end.
Also took a SQ 747 from Singapore to Melbourne overnight in 2005. I got an emergency exit seat - but the one right by the door, meaning I ended up with less leg room than a regular seat due to the protrusion from the door. It was not comfortable.
I also managed one from Nadi to Sydney with Air Pacific/Fiji Air at around the time they were retiring the ex-Ansett 747s and rebranding. I'd taken a brand new A330 on the way over so I got the best of both worlds.
Last 747 flight was last year, Thai from Tokyo Haneda to Bangkok. It was a pleasant flight with a great view of Mt Fuji. I expect that will remain the last 747 flight I take, mores the pity.
I believe I took other 747s when I was a wee lad, but these are the ones in my living memory.
