Radically this problem is not rare around the world in which the children become a pain. In a way, it is so natural for children to make a noise at public places due to immature moral consciousness. So, as far as I'm concerned, as the news title says, it is the best way for now to run a Child-Free flight for someone whose sensitive to this kind of things. That way, the airline can cost these people more fee for this exceptional service, in order words, these people can get satisfying services for added fee.
But if they can't afford to do so, preparing some toys or snacks, candy(?) could be good measure... in order to have their mouth zip shut = keep their mouth shut. maybe haha lol
