Dublin airport airside interconnection
I have a friend without a Schengen visa who is likely to be travelling to the US on a route involving a transfer in Dublin. Dublin on a low-cost flight would be much easier and cheaper for me to reach than either the US or their home base, so I was wondering about the feasibility of us meeting up airside for a couple of hours.
Does the terminal arrangement at Dublin allow, legitimately, SLF to disembark from an incoming Schengen flight and stay airside to move to a departure lounge (if necesseary in another terminal) before exiting?
