IIRC, our first 747 flights were a couple in 2010, SFO-SYD in the knee-grinding bulkhead row (19) in E+, but then have had a span of 1k years & somewhere around 30 TPAC legs in Business, the vast majority in a 747 Upper Deck. Latest was earlier this year (ICN-SFO Upper Deck) ... didn't realize until recently that it was our valedictory 747 experience. Farewell ... it was great while it lasted. Wondering if other carriers will be still be using 747s or turning to that great big Airbus? Oh wait, aren't the new POTUS planes 747s ?
