This is a false equivalence. Air travel is a tightly regulated business and all flights are registered with and regulated by the FAA, which requires certain information about all flights to be publicly exposed. Thus, a function of air travel is that publicly available information is governmentally mandated to exist. The usage of this publicly available information is clearly enshrined. The day to day of a child on the other hand is something that should not have information published publicly about, and entities who were to collect and share this information may be violating the law. I will not comment too much on the legality, but the ethics of such an action as described are also extremely questionable.
