Wide-body aircrafts with lots of space inside to walk around every few hours in a 12 hour flight are great. For such long trips, I prefer the big B747 or A380 over these ultra long wide-body but still quite claustrophobic narrow low ceiling noisy aircrafts (e.g. B777) that barely have enough restrooms fitted in.
