However, being there is no such epidemic of child abuse on airplanes in mid flight, then if the airline wants to "protect" the children they should do so in a gender neutral manner.
Solution: Always place children next to an open seat, regardless of how many paying passengers are displaced. In this manner, the airline can put its money where its mouth is, so to speak.
But did you also see the story about the Swiss Santa Clauses who are now forbidden to carry children on their laps, for fear of being accused (falsely or otherwise) of child abuse? Seems the Swiss authorities are doing this to "protect" the Santas, as a proactive measure.
Doc, good to hear from you again, how's the weather in your part of the world?
Good Luck.
