Baggage allowance for this journey

Your baggage allowance depends on the ticket, cabin class, operating airline and, sometimes, the countries on the journey. A common or advertised allowance does not automatically apply to every fare. You can check available fare-specific policy details, then verify them with your airline before you pack.

Passports, entry rules and connecting flights

This journey involves airports in Ireland and United Kingdom. Check the current passport, visa or electronic travel authorisation rules for your citizenship, transit points and booking before travel. If your journey includes separate tickets or connections, confirm who handles checked baggage and how much time you need between flights.

What if your flight is delayed or cancelled?

Flight disruption rights depend on the applicable territory, operating airline, delay at the final destination and the reason for the disruption. A live plane position does not establish whether a flight is officially on time.

For this route, start with the passenger rights framework relevant to Ireland. Keep the flight notification, booking details and receipts in case you need assistance or make a claim.
