I spend between 600-800h a year in the air as pax, vast majority in J or F, and as much as I can assure everyone here that the 787 is the worst product I've flown on in decades, this means squat to the managers that make the decision on what to buy. They base it purely on cost benefit. I am yet to experience the A350 - I've considered taking a detour on one of my next trips just for that purpose, I'm curious whether I perceive the 787 as so crappy just because of its small cabin size and noise level. For pax comfort, the A380 is hard to beat in my view. Spending serious time stuck inside aircraft, what matters to me is noise level, personal space, and lavatories. The 787 has shortcomings in all of those categories, regardless of operator.
