apologies if there’s an existing thread- I did a search and couldn’t find anything recent

i’m looking to fly in the pointy end of a 747 before they’re retired. Qantas don’t sell first class on theirs anymore so I started looking at BA

so far the only semi workable option I can see is CPT (would connect from JNB which has a qantas service)
Dubai is out as qantas cap status credits
i heard Beijing is a 747 route but not showing as such on the dates I searched (into London around the 17th December and back out again on the 23/24th)

any help gratefully received!
