I had the pleasure of flying on a 787 recently and was very impressed. The wide cabinand those dimming large windows and the smoothness of takeoff through landing was very nice. Never been on an A380 but would like to experience it once for bucket list reasons.
I would expect the A380 to be comfortable, but that many people on board gives me the willies.
I read the Joe Sutter book “747”, and if you like aviation, it is a must read!
