787's are super cool. I happened to fly back from Japan on one before their (first?) grounding and it was quite enjoyable. The additional cabin pressure for a "lower altitude feeling" and lower noise do really help reduce fatigue.

Ohhh they have additional cabin pressure? I could swear the air quality was MUCH better after spending about 10 hours in the plane and not feeling any fatigue.

I thought the air was less dry too, but didn't really have means to measure that.

It is less dry. The 787 can be held to a higher RH% because of its carbon fuselage. No worries about rust. Furthermore, it's not pressurized with engine bleed air which is very hot and dry.

787 is indeed comfortable but during landing every single time I thought the plane is going to burst into pieces - the loud rattling noise and visible bending of the interior was just crazy. But other than that really cool.

Aluminum planes also bend visibly if you're sitting in a rear aisle.
