Re: A380 is great, so silent inside! Scrap those noise old B747 and B777!!
"Sadly customers do not seem to care about their experience and always choose cheaper one, which happens to be with more denser seating."
It is not like we have a choice! Once you have chosen your start and destination, and the dates to travel, you are lucky if you have more than 2 airline choices. After rejecting the 'I'd never fly with them' airlines, you are usually left with 1 or 2, and they don't even tell you which plane make/type/config you will be flying on.
The first time I know what plane I'm flying on is usually when I go to book my seat online.
