I read that Malaysia Airlines is attempting to have a separate section for families with kids:
If there is an airplane built for creating a zone where you won’t find children, it’s the double- decker Airbus A380. Malaysia Airlines begins flying this whale of an aircraft July 1 and is attempting to restrict families traveling with children to the all-economy lower deck…
So far no U.S. airlines enforce children-only seating sections.
While I don’t like this idea as it seems a bit discriminatory, at least if there were no children allowed in adult-only sections, men would not have to worry about being discriminated against when a child is seated next to them.
