Across the skies, there's a growing debate over whether airlines should do more to segregate the seating of passengers -- with designated areas for kids, for example. At a time when increasingly crowded jets have helped to make flying less pleasant for many passengers and social media allow them to instantly tweet their frustrations to the world, a comfortable perch on the plane -- and some tranquility around it -- has become ever more precious.
Polls of fliers by the travel search site Skyscanner and of business travelers by Britain's Business Travel & Meetings Show indicate a majority of airline passengers want sections set aside for families, or cabins that are for adults only. Overweight passengers have complained about being humiliated as airlines enforce rules that they pay for a second seat so they won't crowd their fellow fliers. And some passenger advocates say that designated rows for those who are tall, heavy or disabled would be a good idea.
