I received email today from a Principal Operations Inspector at the FAA, who indicated that although “air travel by unaccompanied minors is a subject that is not regulated by the FAA… your complaint has caused us to look at other issues surrounding your daughter’s situation, and we are investigating those issues.”
I asked him for additional details about what they are investigating, but he was unable to provide any at this time. He did, however, say that I would be notified when the investigation is complete, and I hope they’ll give me more details then.
My guess, and my hope, is that what they are investigating is how two different planes could take off with the wrong number of passengers, and how a passenger could go down a ramp onto the tarmac and then not get on the plane without anyone noticing. That issue is relevant not only to the correct routing of unaccompanied minors, but also to travel security.
