Raz just in case you're not aware, the Dreamliner is a big advance, carbon composite plane (rather than traditional aluminium) meaning its lighter & stronger kg for kg.
It allows the cabin pressure to be kept at around 6000 ft altitude, about 2000 ft lower than on other planes, and the humidity level is kept at a more comfortable level for pax (because water is extra weight on a plane & corrodes aluminium) so much reduces passenger fatigue, dry eyes & nose, headaches etc. Also the extra strong carbon composite allows the cabin windows to be about 30% larger so much nicer looking out at the view.
There certainly is quite a difference in terms of passenger comfort matching like for like configuration.
Lighter weight also better economics for the airline.
