Cheap flights from Dublin to Cardiff

Travel costs tend to rise during holiday periods and school breaks in December and January before settling into lower fares. October offers some of the most reasonable prices for this crossing, with September and November also showing competitive rates if you plan ahead. Weekday departures generally cost less than weekend flights on any given month.

Full-service carriers like KLM Royal Dutch Airlines, British Airways, Aer Lingus and Air France typically include checked baggage in their fares but require connections through Amsterdam or Paris. Low-cost options such as Ryanair and Emerald Airlines keep base prices lower while charging separately for extras on direct services. Regional operators including HOP! and BA CityFlyer provide additional scheduling flexibility across the route.

Cardiff Airport sits a reasonable distance from the city centre, with bus connections running regularly to downtown destinations. Taxis are available outside arrivals but expect higher costs during peak hours or late evening flights. The transfer usually takes around half an hour depending on traffic conditions and your final destination within Cardiff.
