Cheap flights from Cardiff to Dublin

Dublin sits on the same latitude as much of Britain, so winter days are short and damp, while late spring brings long evenings and milder air. January is the cheapest month on this route, which fits the pattern: fewer people cross for city breaks once the festive season ends. School holidays and Christmas push fares up in both directions, and summer weekends are pricier than midweek. If your dates are flexible, travelling outside those peaks and midweek rather than Friday tends to cost less.

Start with the connecting carriers: KLM Royal Dutch Airlines and KLM Cityhopper route you through Amsterdam Schiphol, and German Airways adds another routing — useful if you want a stopover, but it turns a short hop into a day of travel. Ryanair and Emerald Airlines fly nonstop and keep fares low, though luggage beyond a small bag usually costs extra. Aer Lingus and TUI Airways also serve the route with full-service fares that typically include a checked bag. Weigh the total price with bags against the nonstop fare before deciding.

Dublin Airport is the only airport serving the city, sitting a short distance north of the centre. Buses and coaches run into town regularly and are the usual way in; a taxi is straightforward too. Allow extra time if you land in the late afternoon when commuter traffic builds. Since every carrier on this route uses the same airport, your onward plans do not change whichever airline you book.

Country facts: Wikidata

• If you book a connecting itinerary through Amsterdam, check whether it is on one ticket or two, since a separate ticket means you protect yourself if the first flight is late.
• Check the baggage allowance before you pay: on Ryanair and Emerald Airlines a small bag may be the only thing included.
• Check that your passport meets Ireland's entry requirements and, if you need one, that any visa is arranged before departure.
• Check the month you plan to fly against the price calendar, since January fares differ sharply from summer ones.
• Check which terminal your airline uses at Dublin so you know where buses and taxis leave from.
