BA6501 am not sure if you should call it harassing, there is a lot of child trafficking and run away kids. When my children weren't off age yet, even up until 18 years of age, I would travel with them having a notarized letter from their father allowing them to fly with me. And would give them such a letter when traveling solo. It is just a precaution with all the s....t that goes on.
Part of what modern society I guess.
