Crying children is one of the many dilemmas of air travel, whether you're a fellow passenger or a poor parent landed with the responsibility of trying to keep your little one quiet.

"There’s nothing that sets off the fireworks as much as Other People’s Kids (OPKs)," notes Christopher Elliott of National Geographic Traveler magazine. "On a recent flight from Honolulu to Los Angeles, I watched an elderly passenger who had the bad luck of being surrounded by screaming kids, one of them, unfortunately, my daughter, who, he remarked, 'acted as if the plane was her personal playground'.

"OPKs are unfixable. All the responsible parenting in the world can’t make up for boredom or pressure in the ears or a really bad in-flight movie. May I recommend a nice pair of earplugs?"
