I'm off to the USA next month for work. My choices are as follows: QF11 (A380) or QF73 (747) into San Fran The reason I'm considering QF73 is that this particular flight won't have any F cabin seats. However my understanding is that QF will allow Biz class passengers access into the F cabin assuming based on status. The service in F will simply be Biz but of course the seating will be better. However it's unknown at this moment whether qantas will actually do this. I would assume that if Biz is not crowded then they'll stick everyone in the one cabin for ease of service. So should I take my chances on QF73 or just suck it out on the A380? QF73 is my choice at the moment because if I don't get into F, then I will end up with a skybed anyway. Whereas the A380 has better biz seating.
