Transit rules depend on your specific routing, so check the country you connect through separately, or analyse your full itinerary.

Your IE citizenship gives you freedom of movement to this destination under EU Treaty rights and the EEA Agreement (Directive 2004/38/EC). This is more than visa-free entry: you may enter with a valid passport or national ID card, stay without a visa, and take up residence, employment, self-employment, or study with no permit. After three months you simply register with local authorities if the country requires it. Your spouse/registered partner and dependent family members can accompany or join you, including non-EU/EEA family members (who may need an entry visa but cannot be charged for the residence right itself). No onward or return ticket is required.
EU/EEA free movement is your right, but on mixed itineraries (a leg outside the area, a codeshare, or a non-EU carrier) check-in agents sometimes apply generic third-country rules and ask for a return ticket or proof of funds you do not need. Carry a valid passport or EU/EEA national ID card; if questioned, reference your EU/EEA citizenship and the right of free movement (Directive 2004/38/EC).
