If this isn't precisely what this forum is used for, then I apologize. Just looking for a different angle, perhaps one based more on personal experience since this has never happened to me or anyone I've spoken to. A plot involves a minor boarding a plane alone from US to England. Through complications involving a predesignated adult to meet him not showing up, he is left alone in Heathrow to figure out what to do next. Basically, I'm looking for aid (hopefully personal experience) in finding out: - Other than passport and arrangements made with adults to deliver him to/pick up from respective airports, what else does the minor need to successfully board the plane? Perhaps a note of permission from a parent/guardian? - What steps are taken by airport officials in the event of an unaccompanied minor? - Furthermore, what would be ways for the minor to remain in the country for a short amount of time? So much as viewing this earns my thanks, let alone any offered aid or insight.
