I live in Italy and I think you were never stopped because it was an internal flight. Again, you are not likely to be stopped at any airport in europeEurope that is part of the schengenSchengen agreement. For instance, I have never been stopped at aiportsairports in Belgium and Holland even though I am a non-europeanEuropean. On therthe other hand, I have to go through normal aiport procedures on my arrival in the UK and Ireland which are not part of the schengenSchengen.
