> I'm surprised to hear you say that, since I find the two very different. 747s are much noisier (unless you're up top) and have less humidity & cabin pressure, making them materially less comfortable on long flights. IMO even on the lower deck the A380 is the quietest jetliner I've been on. The last 747 I was on (United) still had the old, comfy, interior. The 787 may have the benefits of a quieter, more humid cabin but the slimline seats and tighter seat pitch made it a much less pleasant experience for me (United was among the worst of the bunch).
