I get your point and I haven't left Europe in more than a decade, but as Juan Trippe said so eloquently "Mass travel by air may prove to be more significant to world destiny than the atom bomb."
If 10%-20% more of the US electorate did visit other countries by means of these fabulous machines...just sayin'
Not following the electorate part of that but there aren't that many countries I'd want to visit. And there are plenty of them that don't like American's anyway.
Now the reason I wouldn't want to fly on an A350, or a 787 and certainly not a A380 is quite simple, and it may seem ridiculous to most of who, but I hate quiet planes. The 777 isn't the loudest out there but it's pretty up there. I have no desire to hear someone scratching their ass crack from 30 rows in front of me and I doubt anyone wants to hear me snoring.
Simple thing, people won't hear you snoring, and people are not going to hear someone else scratching themselves. The A380 is a quiet plane, but it is not silent. It still has engine noise, and there is still the air-conditioning noise. Just that it doesn't thunder away like a 747 or a 777. Even on the A380, I'm still putting on my headphones to block the engine noise.
Perhaps you really should be travelling in the back rows of the IL-62 or near the back of a TU-154 instead. I know your comment was hyperbole, but it's a bit over the top.
Probably because the 779 is a derivative of a plane that's been in service for 22 years, while the A359 is a brand new plane that's still a rare sight at most airports.
To this day, I've only ever seen a LATAM A350-900 in Munich. Never any others. It was only chance because I was going through that airport.
