I've never noticed anyone from the department of social protection checking boarding passes at the airport. Most people leaving through Dublin Airport use the self service scanners. People arriving have their passports checked by I don't travel that much now but up until a few years ago I was averaging about 40 outbound flights a year from Dublin. Those arriving go through passport control which is staffed by the Border Management Unit (BMU), which is under the directorship of the Irish Naturalisation and Immigration Service (INIS) of the Department of Justice and Equality. Are you saying those guys check to see if people are on welfare?
