4700nm in a narrow body ???
Although the distances were shorter but before the 747 came along, everyone travelled in what we call today a 'narrow-body'. I've absolutely no recollection of anyone ever comparing about the lack of comfort in a B707 or DC8. I think people are much softer and more spoit in 2021 than they were 40 or 50+ years ago! Our ancestors, wherever they are, must be laughing at us.
