The unaccompanied minor is a part and parcel of every airline service. The child is accompanied by an airplace employee from the time the child is taken to the aiport until surrendered to the other adult at the landing site. I cannot tel you if a judge will order it, and you can certainly express your concerns, but the father is within his rights to see the child, and I doubt a court will be too concerned about a child travelling in the manner I have described. This would be a completely different answer for a train or bus, but airlines are set up for this type of situation.
