S.o.S.
I have also flown many miles in 747, mostly 200model onwards. Always liked sitting upstairs as it was like a private club with better staff to customer ratio, especially when it was BA back in the day. However times change for both 747 and BA. I will still fly on 747-8 with LH as they are used on some routes I am currently (hopefully !) going to be using, indeed my last 747 flight was on an series' 8 earlier this year. I have to say the 380 is a better AC as a passenger experience, though in a historical context the 747 was a game changer which the 380 will never be.
Kind regards
Mr Mac
