They have business class, first class, coach etc. Maybe it is time for a family area. And, I am not being facetious. Seriously, seating that is more kid-friendly/family friendly and maybe with some sort of insulated divider. I would also be willing to pay a little more for an adults only flight. There are so many ways to address this. I am also someone who believes that, if I am willing to pay for the seat, I should be able to bring my well-behaved, crated/kenneled pet in the cabin with me, belted in a seat.
I know none of that will ever happen. They are aiming for smaller to non-existent seating, not gearing for customer friendly, at all.
