Flying from USA into FCO a few hours before son flies in from LHR. Would like to meet up with him at airport, hopefully before immigration/customs. Any suggested easy to find meeting places pre- and post- secured areas?
That might not be possible. First, you have to go immigrations since you are arriving from the US. He will not IF he is only catching a flight from LHR and you could be using different terminals.
Ron in Rome has great info on this: the link is: http://www.roninrome.com/2009/06/10/where-to-meet-at-fco/
