I was wondering if folks with ample experience flying F on both the A380 and B777 could opine on the differentiation between the two products as related to external noise levels, and degree of impact during turbulent weather. Mrs B does not sleep well on long haul flights and we have our first trip to Asia on the horizon, and total flight time will be the longest flights we have ever done. I suspect external noise levels are in part a function of location of F cabin, but otherwise no discernible difference. I am particulary wondering if A380 due to its overall size is less affected by turbulent weather. Any opinions greatly appreciated.
