Ever been on a plane headed to or from MCO?
My god.
But, as others have said, the kids paid one way or another to sit there. It's up to the parents to keep them in check, and not go off duty and assume it's the FA's job to entertain the brats...I mean well behaved angels.
I flew up front with my parents a lot when I was young. They always had an arsenal of things to keep me busy, i.e. books, snacks, games, toys, etc. My bro and I were always well behaved thanks to good parenting.
