Thank you very much for that info, that makes sense now
However, the only time I was asked for my passport was at Passport Control in Dublin.
At the gate all the woman did was tear off the slip on my boarding pass. I suprised that it wasn't scanned (she manually checked that my destination was DUB by looking at the card) but not being asked for my passport/identification was even more suprising...the flight was behind schedule, could that be why?
Or could it have been a mistake maybe?
