Some of memory is a bit sketchy but as a child i flew to florida from the uk as a um. I did this a few times but i do remember that my dad would pay the extra charge to have someone meet me the other end and escort me through the airport. He would never have considered skimping in this area or booking me on a flight with a connection no matter what cost, I would have been terrified at the thought! Parents have to take responsibility instead of placing ALL blame on the airline.
