Interesting that this organization works with Courage Worldwide. They are involved with a training program for flight attendants http://airlineamb.org/our-programs/human-trafficking-awareness/aai-presentation/. From the powerpoint slides (re: slide 31) you can see that flight attendants are told NOT to: confront anyone, or try to rescue a child, or display any concern. Instead to call a trafficking hotline.*

And that would be the National Human Trafficking Hotline (NHTH) https://humantraffickinghotline.org/about-nhtrc/join-team. And they are run by a charity called Polaris https://polarisproject.org/about. And they share data and collaborate with the Clinton Foundation https://www.clintonfoundation.org/blog/tag/human-trafficking
