Nothing wrong with the 787. I had the "privilege" to fly in one as a passenger with PornStar from Sydney- Honolulu. I have picked the emergency exit seat since I am a tad over 6 feet so I can stretch my legs. Mind you the flight was during the night so it was extremely smooth and I can't sleep unless I am in the cockpit.
...I thought it was a comfortable aircraft to be passenging. If you were into peeking outside the 40% larger windows were a plus...
